Starbucks nears 2025 goal for 10,000 “greener stores”

Key takeaways

  • Operations are among the biggest sources of emissions for fast-food restaurants.
  • The Greener Stores framework outlines 25 practices store managers can use to reduce energy and water consumption, and minimize packaging and food waste.
  • Starbucks focused first on new locations, but existing cafes are encouraged to embrace Greener Stores habits.

Starbucks has verified 9,400 cafes for meeting strict requirements related to energy efficiency, waste diversion and water stewardship. 

That’s more than double what it reported in 2024 and just shy of the 10,000 locations it aims to certify by the end of 2025, the coffee chain said in an April 22 update.

Starbucks manages close to 40,200 retail locations globally, so roughly one-quarter of its locations are now certified. It introduced the Greener Stores initiative in 2018, and saves an average of $60 million annually in operating costs as a result. That’s due to the 30 percent average reductions in energy and water consumption that these stores report.

Starbucks is one of several high-profile fast-food restaurant chains encouraging waste, energy and water efficiency to help curb emissions. KFC, for example, builds certain requirements into franchise agreements. Scope 3 emissions tied to these locations are among the biggest contributors to these companies’ carbon footprint.

Starbucks’ Greener Stores framework, which it developed in collaboration with World Wildlife Fund, covers 25 practices that define the construction and operation of new cafes and retrofits of existing locations.

Examples of measures that count toward certification include sourcing electricity from solar, wind or other clean power sources; using energy-efficient equipment such as refrigerators with low global warming-potential coolants; and embracing initiatives for diverting packaging and food waste. 

Starbucks stores can also get credit for adding renewable energy installations, such as solar panels, or for investments that support electrification, including electric vehicle charging stations.

In the U.S., Starbucks is pushing for the installation of more than 100 direct current systems that speed charging, starting with a corridor between northern California and Washington state that it described as a charging desert. It has so far installed 34 units in collaboration with Mercedes-Benz, according to the April 22 update.

Lessons from the emerging effort to advance ‘circular’ textiles in health care

Key takeaways

  • New regulations and global pressure are accelerating the shift toward more sustainable medical garments.
  • Most medical textiles are not recycled, contributing to health care’s large climate and plastic waste footprint.
  • Startups FIGS and AmorSui are serving sector professionals seeking to reduce those impacts, with “circular” scrubs and lab coats.

The lives of medical textiles are brutish and short. Nurses and doctors often wear scrubs and lab coats to death within a year. Some masks and exam gowns only last for minutes before landing in the trash.

Small wonder that health care, which creates 4.7 billion tons of annual waste, contributes more than 4 percent of the planet’s climate emissions, according to the United Nations. More than two-thirds of that comes from indirect Scope 3 sources, including textiles and other medical supplies.

But a growing number of small makers of “circular” scrubs, lab coats and gowns are finding a niche among health care institutions that strive to reduce waste and emissions — and satisfy emerging regulations.

Meanwhile, researchers are testing ways to keep medical textiles in circulation. For example, scrubs maker FIGS and lab coat brand AmorSui are expanding recycling options.

Regulations and waste piles

Starting in 2026, part of a new California law takes effect that will force health care customers and distributors to manage worn-out lab coats, gowns and drapes in environmentally friendlier ways. The state’s Responsible Textile Recovery Act, which took effect Jan. 1, is among the early extended producer responsibility (EPR) laws in the U.S., and the first to govern garments rather than packaging.

Efforts to expand textile recycling and reuse also come as multinational negotiations continue over a Global Plastics Treaty.

“We want to encourage more circular approaches, where waste is avoided, the materials are reused,” said Will Clark, executive director of Health Care without Harm in Europe. “It’s this hierarchy of preventing waste, reusing products or avoiding single use.”

Textiles make up between 14 and 31 percent of waste in the industry, according to nonprofit Health Care Without Harm, based in Reston, Virginia. Single-use items, such as polypropylene masks, examination gowns, surgical drapes and shoe covers, account for nearly 10 percent of plastic waste in hospitals.

Gowns and scrubs, at least, are already “circular” in some sense because health care professionals re-wear them. Yet these garments often blend synthetic polyester and spandex with cotton, making them hard to recycle. Fluid- or microbe-resistant finishes add further complexity.

Pilot projects

The nonprofit is in the middle of a two-year partnership with the Norwegian Retailers Environment Fund to encourage health care providers to adopt reusable gowns, aprons, masks, wraps and drapes. Health Care Without Harm is working with hospitals in the U.K., Colombia, Brazil and the Philippines to identify the potential for using and scaling similar materials in local markets.

The projects seek to prove the existence of demand for less wasteful practices and products. That’s challenging in a heavily regulated industry in which infection prevention specialists often gate-keep against change, added Clark, a former health service sustainability director.

“A big concern about medical waste, and recycling it back into medical products, is the biohazard risk,” said Marcian Lee, an analyst specializing in plastics at Lux Research in Singapore. “Even if we were to design medical products to be reusable, it takes energy to sterilize them for reuse. So sometimes its just that so much easier, probably cheaper and maybe safer to just use disposable.”

A scrubs solution

FIGS specializes in what it pitches as less “itchy” scrubs. “We want to make it seamless for health care professionals to easily swap out their old scrubs that suck and replace them with FIGS, and to do so without creating waste,” a spokesperson for the Santa Monica, California, company told Trellis.

On April 3, the 12-year-old business launched a recycling program that allowed customers to either mail back their unwanted scrubs or bring them to centers in Los Angeles and Philadelphia. It follows a one-month pilot last year that downcycled more than 45,000 pounds of scrubs into sporting gear filler, carpet underlayment and car insulation.

FIGS’ reverse logistics partner is SuperCircle, based in New York. The 7-year-old infrastructure startup collects, identifies and sorts garments, then provides textiles to 20 specialized recyclers. In working with brands such as Reformation, J.Crew and Guess, SuperCircle says it has prevented the waste of more than 2 million garments. These recycling efforts are profitable and drive customer loyalty, according to SuperCircle.

“Roughly 40 percent of what we process is fiber-to-fiber recycled and turned into new textiles, while about 60 percent go to open-loop recycling, becoming long-life products like insulation or industrial materials,” a SuperCircle spokesperson said. “We only work with open-loop recycling partners who extend the fiber’s life by at least five years. So nothing becomes short-term waste.”

Because scrubs lack complex fasteners and trims, they’re relatively easily shredded for recycling without a lot of prep work. However, FIGS main fabric, FIONx, blends a majority of polyester with roughly one-fifth rayon and a lesser portion of spandex. Conventional recyclers groan about such blends, a technical challenge that microbial and chemical recyclers are competing to solve.

Although it’s not a perfectly circular, textile-to-textile solution, the company is working toward other materials milestones. By 2030, it aims for 75 percent of its scrubs fabric to come from “recycled and upcycled” materials. Another goal is for 30 percent of materials for fabrics, buttons and zippers to contain 30 percent recycled ingredients or traceable fibers.

Nylon lab gowns

AmorSui, by contrast, is focusing on single-material lab jackets and other garments to simplify recycling. It also makes “zero waste” gowns, as well as fire-resistant scrub sets and hijabs.

The company’s garments are used in 15 hospitals across the U.S. In recent months, more health care systems have been asking about end-of-life solutions for textiles, according to AmorSui Founder and CEO Beau Wangtrakuldee.

Since it launched in 2018, the Philadelphia company has seen 100 percent year-over-year growth, she said. Larger hospital systems with established sustainability programs are increasingly interested as they focus their decarbonization efforts toward the carbon footprint of their supply chains.

Scope 3 emissions, including from supplies, contribute to 71 percent of the sector’s greenhouse gases, according to a 2019 study.

AmorSui is transitioning away from polyester, as well as trims such as metal snaps that complicate recycling. “We are moving towards developing a mono-material garment, meaning that all the trims and everything are made from just circular nylon,” Wangtrakuldee said. “It allows us to not have to do a lot of labor in terms of sourcing, which saves costs in a long run and also allows the garment to be 100 percent reclaimed, 100 percent recyclable and 100 percent recycled.”

Compared with polyester or cotton, nylon is light, repels fluids and dries more easily, she added. AmorSui sources the nylon in the U.S. Another partner performs chemical recycling to turn worn garments back into raw material that can be spun into a new yarn. But that involves pyrolysis, which is controversial. This nylon does not generate “forever chemical” PFAS (per- and polyfluoroalkyl substances), according to Wangtrakuldee.

Established players

In contrast to the startups, a thriving ecosystem of companies that rent reusable textiles to hospitals and clinics emerged from the informal rag trade more than a century ago. The Textile Rental Services Association (TRSA) of Alexandria, Virginia, represents hundreds of members, including uniform provider Cintas and numerous regional laundering services.

The TRSA’s North American members process 40 billion pounds of healthcare textiles, including scrubs, lab coats and bed sheets, each year. Recycling is the missing link in this near-circular industry, due partly to the complexity of blended textiles. “It’s just going to take time, and logistics is just as much of a problem as anything else,” said TRSA President and CEO Joseph Ricci.

Corporate climate policy still works: 4 lessons from 100 meetings on Capitol Hill in March

Key takeaways

  • Despite popular belief, conversations happening on Capitol Hill regarding clean energy tax credits and incentives are cordial, respectful and productive.
  • Government affairs and sustainability teams can work closely to ensure advocacy opportunities are as high impact and low risk as possible.
  • Even if lawmakers don’t care about climate change, framing environmental issues in terms of things they do care about — U.S. competitiveness, job creation and more — can transcend politics.

U.S. sustainability professionals have faced daunting challenges in the opening months of 2025. The Trump administration appears resistant to climate action and a series of executive orders and new tariffs have added to the uncertainty. All of this makes it hard to push for strong climate policies. But from where I sit, sustainability leaders have the opportunity to transcend the politics of the moment with compelling stories about the business case for long-term investments in the clean energy economy. Last month, I helped convene dozens of large companies on Capitol Hill to do just that — and I learned a lot from the experience.

In this volatile moment, here are a few ways sustainability leaders can better align their specific climate goals with their company’s policy engagement strategy:

Find strength in numbers

In March, at the outset of the ongoing budget negotiations in Washington, 80 large companies and investors took to Capitol Hill for meetings with about 100 Congressional offices, the vast majority of which were Republican, to call on lawmakers to keep federal clean energy tax credits and incentives in place. The message was direct, but the conversations were incredibly cordial, respectful and productive. Importantly, we have not heard of a single company receiving any kind of political blowback as a result. 

In fact, the feedback has been quite the opposite: just days after we left D.C., 21 Republican members of Congress released a letter emphasizing their support for maintaining the incentives amid ongoing tax debates. And this month, four Senate Republicans followed up with a supportive letter of their own.

There are many ways to attribute this success, but undoubtedly one of the most important is that the large-scale, cross-sector and collective business voice created a virtuous cycle. Not only did it provide validation to lawmakers that leading companies want and need clean energy tax credits, but the multi-sector “big tent” approach creates a comfortable and safe space for businesses to direct their advocacy, further amplifying the impact. Businesses committed to climate and sustainability leadership can join cross-sectoral opportunities such as these and consider putting their name on strategic sign-on letters and other opportunities to collectively weigh in.

Link policy priorities to business goals

Climate change will affect the entire economy, so at some level all climate policies are business concerns. But that concept is too broad and abstract to drive meaningful policy action. Effective business advocates lead with the issues that are central to their business’s operations. Ford Motor Co., for example, has publicly advocated for maintaining federal clean vehicle and battery tax credits, which have guided the company’s long-term investment decisions and are key to growing the manufacturing and adoption of electric vehicles.

While that example gets directly at Ford’s business operations, companies should have no trouble advocating for more tangential policies that have a clear business impact. With energy prices too high and the grid constrained, it makes sense for nearly every company to advocate for policies that support the rapid deployment of clean energy resources such as solar and battery storage, as they’re the most affordable and quickest-to-build forms of new power.

Prioritize government affairs

Sustainability and government affairs teams need to work closely together during this turbulent time. Government affairs staff are understandably buried by the barrage of complex and unpredictable policy changes coming their way. Sustainability professionals should flag discreet policy priorities early and often, and make a compelling case that links timely advocacy to core business priorities.

They can also ensure that advocacy opportunities are as high impact and low risk as possible. Think about ways to frame issues in a way that will appeal to lawmakers who simply may not care about climate change or pollution — but could be receptive to arguments about clean energy affordability, job creation, global U.S. competitiveness and innovation. Time and time again, we’ve seen that the economic case can transcend politics. And there are ample opportunities to work as part of a group with peer companies or with businesses across sectors.

Consider corporate credibility

While it’s understandable that a changing political environment could affect companies’ approach to publicly supporting climate policy, it’s conspicuous when a business that once described something as a core principle no longer prioritizes it. No one is expecting companies to weigh in on or respond to every individual policy move. But investors — who continue to prioritize corporate climate advocacy — will take note if businesses aren’t engaging. Lawmakers will notice as well. Silence, after all, is a message of its own.

How to propose climate legislation in today’s political climate

Key takeaways

  • Two prominent Republicans have reintroduced a bill to hold foreign importers accountable for carbon emissions.
  • But the Foreign Pollution Fee Act (FPFA) could increase domestic emissions as manufacturers ramp up production to compensate for fewer imports.

Republican Sens. Lindsey Graham (S.C.) and Bill Cassidy (La.) reintroduced a 2023 bill that would impose a 15 percent tax on imported goods containing aluminum, cement, iron and steel, fertilizer, glass and hydrogen. If passed, the Foreign Pollution Fee Act (FPFA) would mean that some countries, including China, Russia, Vietnam, India and Taiwan, could face fees of as much as 200 percent after previously levied tariffs are factored in.

To avoid tariffs, companies can either purchase carbon credits or capture carbon emissions released in their business operations.

In a time of hyper-partisanship and continuous attacks on climate-mitigation funding from the Trump administration, the FPFA serves as blueprint for other bills addressing climate change.

Thibault Denamiel, a fellow at Center for Strategic and International Studies, noted the specificity of the bill’s language, explaining that transparently labeling the bill in any way would likely slow momentum towards passage. “FPFA doesn’t mention the words ‘carbon’ or ‘climate,’” he said.

FPFA impact: the good, the bad, the less innovative

If passed, FPFA’s impact on U.S. manufacturing would be significant, as it will doubtless spur production to accommodate suddenly unmet demand. But that could mean an increase in carbon emissions as manufacturers anxious to seize economic opportunities turn to suppliers that rely on energy derived from coal and natural gas.

“As you put these tariffs on foreign goods,” Denamiel said, “replacing them with domestic products will likely involve sources that are less clean.”

Denamiel also worries that pressure to fill in supply chain holes quickly will lead to a slowdown in innovation, “especially in green technologies,” as scrambling manufacturers have fewer resources to devote to R&D.

These 26 Republicans support preserving IRA energy credits

The 2022 Inflation Reduction Act (IRA) created dozens of clean energy tax credits that allowed businesses across the country to decarbonize their operations. Now, the Biden-era law is under threat, with many GOP lawmakers expressing desires to cut many of the same clean energy credits that created hundred of jobs in their states.

However, there are still ways for businesses to lobby for the preservation of certain IRA credits. At least 26 Republican senators and congressmen have publicly expressed a desire to maintain specific credits, arguing that their districts and states will lose jobs and revenue should the credits be cut.

Specifically, 21 House Republicans and four senators wrote separate letters to the Chair of the House Ways & Means Committee Jason Smith and Senate Majority Leader John Thune, respectively, while Sen. Todd Young (R-Ind.) stated in an interview that he was examining different IRA credits within his state. These 26 representatives are more likely to continue to strongly push for the permanent preservation of energy credits if businesses within their states contact them directly. Below are all 26 representatives, their contact information, and a link to the public statement they made.

The Global South: What Jamaica can teach us about climate financing

The Global South – home to most of the world’s population – is where most of the planet’s economic growth and greenhouse gas emission growth is taking place. In the runup to COP30 in Brazil later this year, we explore how a sample of these economies are shaping climate financing. 

Key takeaways

  • Jamaica has been at the forefront of climate financing since becoming the first country to issue a climate catastrophe bond in 2021.
  • By pioneering financial mechanisms to mitigate climate change, sustainability leaders have been able to make important strides in areas such as sustainable agriculture and renewable energy.
  • Investors have opportunities to diversify their portfolio through Jamaica’s stock exchange and via bank and credit unions that have climate-friendly loans for solar panels and electric vehicles.

Here’s a little-known fact about Jamaica: it was the first country to issue a climate catastrophe bond in 2021. And last year, its development bank invested equity into a sustainability-oriented venture capital fund. 

Such moves have helped the island in the Caribbean earn a reputation for pioneering financial mechanisms to mitigate climate change, making important strides in areas such as sustainable agriculture and renewable energy. As UnaMay Gordon, former head of the Climate Change Division in Jamaica’s Ministry of Economic Growth and Job Creation, puts it, “Investment advances in Jamaica can provide a model for the Global South.”

Because much of the climate action that will move the needle takes place in low- and middle-income countries, sustainability leaders need to be especially attuned to how the global majority approaches climate solutions. The opportunities for trade, investment and cooperation are boundless. Whether it’s to reach a science-based target or reduce a corporate carbon footprint, investing in emerging and frontier market climate opportunities is vital to a company’s contribution to a thriving global economy.

From bonds to plant-based cuisine

Since the issuance of the first climate disaster bond, the Development Bank of Jamaica (DBJ) has provided grants, loans and equity for small and medium-sized enterprises geared towards climate. Last year, DBJ invested almost $5 million into a $50 million venture capital fund that invests in climate-focused companies. Around the same time, the Jamaican government approved a 50 megawatt solar farm for SunTerra Energy to build, own and operate. 

On the heels of these investments, the Jamaican government has set a target of producing at least half of its electricity from renewable energy by 2030. To incentivize consumers, the government has set up ways for users to send electricity back to the grid and receive compensation and provided an income tax credit of 30 percent of the purchase cost of rooftop solar, up to roughly $25,000. For businesses, Jamaica gave a 25-30 percent income tax reduction for large scale renewable projects valued at $1 billion or higher, and the suspension of an import tax on many climate solutions, including wind turbines, inverters and solar panels. 

On the transportation end, government incentives for EV growth include a reduced 10 percent import duty (as opposed to a 30 percent duty for internal combustion engine vehicles) and no license fees. Businesses also benefit from the suspension of the Common External Tariff on lithium-ion batteries. 

On the food, agriculture and land use side of climate, the Jamaican market for both plant-based cuisine and natural carbon sink restoration is attractive. Jamaica is home to an authentically local vegan cuisine known as ital (pronounced eye-tal) and has the potential to expand its role as a food exporter and proponent of sustainable, plant-based diets. Jamaica is also illustrating climate leadership by embarking on an ambitious project to restore mangroves. Rachael Barrett, trustee of the Alligator Head Foundation, said the project is “a model that can be replicated in other regions facing similar challenges due to climate change and coastal development.”

Investment opportunities

For investors, emerging market stocks are an important element of portfolio diversification and alpha creation, and Jamaica is no exception. The Jamaica Stock Exchange (JSE) provided the highest returns in the world in 2019 and continues to recover after the COVID-era downturn. Apart from buying shares in JSE-listed climate companies, such as those highlighted by Carbon Collective, retail investors can open savings accounts in Jamaican banks and credit unions that include climate-friendly loans for solar panels and electric vehicles.  

And with approximately the same number of Jamaicans living outside of the island as on it, the Jamaican diaspora is a powerful economic contributor, providing roughly $3 billion annually to the country. As a result, a cottage industry of investment firms, such as Blue Mahoe Capital, have cropped up to cater to the diaspora via retail bond and equity offerings that include climate solutions. 

Looking ahead

As with all economies, a number of changes could help support a more climate-friendly society. For example, the average consumer cannot afford the $31,000 price tag on current EVs in the Jamaican market. There’s an opportunity for more affordable models to enter the island, such as those proposed by BYD Auto and Wuling Motors. And while Jamaica’s 25 credit unions and eight commercial banks provide services to about 80 percent of the population, only a handful provide a full suite of climate-friendly products. Encouraging credit unions and banks to extend affordable loans to households and businesses would go a long way in enabling climate action.

Of course, one would be remiss to not mention one of Jamaica’s most globally known attributes — its annual $4.3 billion hospitality industry. Tourism is a way for solar developers and other green manufacturers to showcase the power of clean energy: this year, Soleco Energy will install solar panels on the iconic Montego Bay resort of Half Moon Bay. Angella Rainford, CEO of Soleco Energy, foresees a bright future: “With ongoing cost reductions for battery energy storage solutions, we believe the rate of solar adoption will only accelerate.”

Microsoft is mining hard drives for rare earths. Why it matters

Key takeaways

  • Technology giants are “mining” rare earth elements and precious metals from old computer hardware and recovered electronics to meet waste reduction goals.
  • Apple and Google are also recovering precious metals and rare earth elements.
  • The company recycled or reused almost 91 percent of its decommissioned servers and other data center hardware in 2024.

Microsoft is expanding electronic waste collection from its data centers with a new initiative to recover rare earth elements and precious metals from hard drives without using acids.

The program announced April 17 is a collaboration between drive maker Western Digital along with Critical Materials Recycling and PedalPoint Recycling. It aims to scale U.S. production of rare earth elements at a time when the world’s biggest supplier, China, has threatened to cut off exports amid an escalating global trade war.  

So far, the pilot has processed 50,000 pounds of obsolete drives collected at Microsoft data centers, extracting rare earth elements including neodymium, praseodymium and dysprosium — crucial components for magnets used in electric vehicles and wind turbines. The initiative has also recovered gold, copper, aluminum and steel.

A Microsoft executive declined to disclose how much of these materials has been recovered, what percentage of end-of-life hard drives was included under the program or whether the company received a financial benefit by participating. 

“This is the right thing to do,” said Rani Borkar, corporate vice president of Azure hardware and systems at Microsoft, pointing to the company’s 2030 zero waste goal. 

Rising demand

Microsoft, like its primary rivals in cloud computing Google and Amazon, is expanding its data center footprint at a furious pace. Hard drives will account for about 80 percent of the data storage capacity at hyperscale and cloud services facilities through 2028, according to forecasts by researcher IDC. This technology depends heavily on rare earth elements and precious metals, as do many systems enabling the clean energy transition.

The materials already recovered from several Microsoft data centers are being fed back into the U.S. supply chain, which accounts for just 15 percent of rare earth production. Other large technology companies, including Apple and Google, are also mining rare earths and other precious metals from old electronics and computer hardware.

No one is doing this at scale. The current U.S. recycling rate for rare earths is less than 10 percent, according to Western Digital. 

The project highlighted by Microsoft uses a multi-step process pioneered by Critical Materials Recycling:

  • Obsolete or old drives are shredded using traditional processes.
  • That material is sorted and processed by PedalPoint, and the magnets and steel are sent to Critical Materials for sorting.
  • Rare earth oxides are extracted using a chemical recycling process that doesn’t contain acids.

“This project isn’t just a milestone, it’s a blueprint for large-scale, domestic recycling of essential metals and materials that will drive sustainable progress for years to come,” said Jackie Jung, vice president of global operations strategy and corporate sustainability at Western Digital. 

Demand for rare earth metals is growing at 9 percent annually, and the market is projected to reach $16.3 billion by 2030.

Microsoft’s zero-waste agenda

The rare earths recovery effort is just one component of Microsoft’s strategy to keep computer hardware out of landfills. It recycled or reused close to 91 percent of the computer servers and other technologies that run its Azure cloud services in 2024, meeting its 2025 target and keeping 3.2 million components in circulation throughout its data centers.

Much of that work is being delivered by Circular Centers, regional sites that handle technology that’s become obsolete for Microsoft’s data center applications. The average lifespan of computer servers is between four and six years, depending on the application. 

Through this program, high-value components such as memory or central processing units are removed and redeployed. Some systems are donated to local organizations such as schools or community groups. 

So far, Microsoft manages six Circular Centers in the U.S., Ireland, the Netherlands and Singapore. It’s planning three more: in Australia, the U.S. and Wales.

Former Energy Secretary Granholm becomes energy strategist

Key takeaways

  • Granholm’s experience revitalizing Michigan’s automotive industry after the Great Recession offers valuable corporate perspective.
  • Her oversight of $200 billion in clean energy projects will inform companies seeking investment opportunities.
  • Her diplomatic skills will shape future public-private partnerships.

Send news about sustainability leadership roles, promotions and departures to [email protected]. Read more Executive Moves.

Jennifer Granholm, the two-term Michigan governor who served as U.S. Secretary of Energy under President Joe Biden, was named senior counselor at “commercial diplomacy” firm DGA Group.

Her job is to advise multinational corporations on energy and infrastructure issues, including the nuclear power renaissance and electric grid modernization, and to help them identify organizational vulnerabilities and opportunities for investment.

“From energy security to industrial transformation, the choices leaders make today will shape their resilience and relevance for years to come,” Granholm said in a statement.

Granholm’s accomplishments include orchestrating Michigan’s economic recovery after the Great Recession, encouraging the auto industry’s wave of investment.

At the Department of Energy, Granholm managed a $200 billion portfolio of investments aimed at accelerating the U.S. transition to clean energy. During the last year of her tenure, in 2024, the U.S. more than doubled its solar power deployments — adding the equivalent of 30 Hoover Dams-worth of zero-carbon electricity. Plans to launch or expand more than 1,000 factories for building clean technologies — e.g., batteries, solar panels, small nuclear reactors — were announced as a result of policies she shaped.

Based on her LinkedIn post about the appointment, you can expect Granholm to focus on furthering “the great work DOE did to reshore and grow manufacturing in the U.S.,” — this time from the private sector perspective. 

“Thanks to everyone out there working to preserve the tax credits — the tool that makes the U.S. energy dominant, energy abundant, and irresistible for investment,” Granholm said.

System for “radical collaboration” on emissions data expands to the U. S.

Key takeaways

  • Multiple automotive companies have piloted the Catena-X data-sharing ecosystem
  • The system is designed to accelerate information flow through value chains
  • Catena-X could serve as the blueprint for similar solutions in other industries

A tool that allows for “radical collaboration” around sustainability data will expand from Europe to the U.S. in the next few months.

Catena-X is a data-sharing ecosystem that automotive industry companies use to exchange product carbon footprints and other sustainability information. The system, developed by BMW and other European companies, was piloted last year. Now, the Automotive Industry Action Group, a non-profit that promotes collaboration between industry partners in the U.S., is gearing up to offer Catena-X to its almost 5,000 member companies.

The system is designed to smooth the countless points of friction that automotive companies encounter when sharing sustainability data — for example, the use of different software systems. Similarly, smaller companies that typically sit deeper in supply chain find it harder to efficiently measure and share data with larger manufacturers.

Common language

Catena-X creates a common language for value-chain partners to use. Oliver Ganser, the BMW vice president who chairs the Catena-X board, likened the system to email protocols that allow users of any relevant software — Gmail or Outlook, for example — to exchange messages seamlessly. “Now SAP can talk to IBM,” he said, referring to two of the tech companies that provide sustainability software to the automotive industry.

In addition to BMW, the Catena-X board includes representatives from Renault, Siemens, Mercedes and others.

The system also includes “kits” that suppliers can use to calculate information they want to share, such as the carbon footprint associated with specific products, as well as rules that allow companies to control which partners have access to commercially sensitive data. 

Catena-X was piloted last year after around three years of development. In one test, a team at BMW’s plant in Landshut, Germany used it to receive data from Covestra, a partner that supplies the kidney-shaped grilles that adorn the front of the company’s cars. The information included all emissions involved in production of the grille, from the extraction of raw materials through the manufacturing process. After being transferred to BMW, the data was integrated with the Siemens software the company uses to track its own emissions numbers.

In another pilot, Witte Automotive, a supplier of door handles and locks to BMW and others, used Catena-X to more efficiently calculate the carbon footprint of one of its products. A third test involved data exchange between three companies — Ford, semiconductor manufacturer Micron and Flex, which designs and produces electronics. Unlike BMW, the trio was not involved in the development of Catena-X.

Expanding stateside

More than 140 companies began to use the system after those pilots were completed and registration opened last October, said Ganser. U.S. companies will soon be invited to join them. Kevin Piotrowski, chief transformation officer at the Automotive Industry Action Group, said that in the next month or two he will announce a formal collaboration with Catena-X and invite his members to use it. “They want to collaborate and share data, but they don’t want to do it five different ways or 10 different ways,” he said. “We’ve got to come up with a standard way.”

Although designed for automotive companies, the emergence of Catena-X raises the possibility that multiple industries might one day plug into a common architecture for sharing sustainability data. For example, Catena-X incorporates core principles developed by the Partnership for Carbon Transparency, an industry-agnostic initiative from the World Business Council for Sustainable Development that has created a standard for sharing Scope 3 data.

“Catena-X is intentionally designed for the automotive sector, addressing its specific complexity, multi-tier supply chains and regulatory demands,” said Ganser. “However, from the beginning it was developed as a blueprint for other industries facing similar challenges.”

Progress report: Apple’s push to use recycled aluminum, rare earths and 13 other materials

Key takeaways

  • A transition to recycled sources also pays off in emissions reductions.
  • Recycled content represented 24 percent of the materials (by mass) in products shipped to customers in 2024. 
  • Barriers to recycled content include trade treaties, limited origin data and scarce supply chain capacity.

Apple’s push to source 15 priority materials entirely from recycled or renewable sources — including aluminum, rare earths and lithium — is paying off in appreciable emissions reductions for its manufacturing processes.

Apple has reduced its greenhouse gas emissions by 60 percent since 2015, on its way to a 75 percent cut by 2030, according to the 2025 Apple Environmental Progress Report published April 16. (Emissions were 15.1 million metric tons, down from 22.6 million in the baseline year.) During the period in question, Apple’s revenue grew 65 percent, to $391 billion.

Much of Apple’s reported reduction came from renewable electricity investments, but sourcing recycled and other lower-carbon materials helped the company avoid 6.2 million metric tons of emissions in 2024. Avoided emissions, sometimes called Scope 4, are calculated by estimating the amount of greenhouse gases that weren’t emitted because of production changes or other measures and subtracting them from historical emissions trends. 

Apple claimed 41 million metric tons in avoided emissions for 2024. Moving to recycled materials accounted for 15 percent of that claimed reduction. For context, product manufacturing activities represent 54 percent of Apple’s overall carbon footprint.

Recycled content from sources certified to ISO 14021 specifications accounted for 24 percent of the materials in Apple products in 2024. The product containing the most recycled materials was the MacBook Air, at 55 percent. A close second is the latest Mac mini: 50 percent of its components come from recycled sources and it is manufactured using renewable energy, making its footprint 80 percent smaller than a mini created using a business-as-usual scenario, Apple said.

The company is prioritizing 15 materials in its recycled content transition, representing 87 percent of its production by mass: aluminum, cobalt, copper, glass, gold, lithium, paper, plastics, rare earth elements, steel, tantalum, tin, titanium, tungsten and zinc.

“Our strategy is to transition to materials that are manufactured using low-carbon energy and recycled content,” the company said in its environmental report. “We’ve prioritized the materials and components that make up a large part of our product carbon footprint to move us closer to our goal of carbon neutrality.”

Spotlight on aluminum

Case in point: Apple used recycled sources for 71 percent of the aluminum it bought in 2024 — a strategy that could prove prescient as manufacturers reckon with Trump-era aluminum tariffs. 

Recycled aluminum is used for the enclosures of pretty much every Apple product: the latest Apple Watch series and Mac mini models, MacBook Air and MacBook Pro, iPads and iPhones. Apple reclaims a portion of that aluminum from old Apple products that it takes back through trade-in programs and procures the rest from other post-consumer and post-industrial sources. 

That initiative has reduced aluminum-related emissions 76 percent since 2015. The material represented 7 percent of Apple’s product manufacturing footprint for 2024, compared with 27 percent in the baseline year.

Apple is also investing in a Canadian venture, called Elysis, commercializing a process to smelt aluminum without emitting direct greenhouse gases. The material isn’t yet available at industrial scale, but it’s been used in some iPhone SE models, circa 2022.

Work in progress

Apple has several other near-term goals for recycled metals and rare earth elements that it’s close to meeting. They include:

  • Recycled cobalt for all Apple-designed batteries: It’s at 99 percent for the batteries; 78 percent of the cobalt sourced for all products in 2024 was recycled, compared with 52 percent in 2023.
  • Recycled sources for all tin soldering and gold plating in certain circuit boards: They represented 99 percent in 2024.
  • Recycled rare earth elements for all magnets: They represent 99 percent of what’s used in Apple batteries and 80 percent for all of Apple’s rare earth needs.

In addition, Apple’s progress on sourcing recycled gold — used in circuit boards, connectors and chips — accelerated from 2021 to 2024. In 2024, recycled gold was used for 40 percent of material in all products, up from 1 percent in 2021. The company doubled the number of suppliers certified to manufacture these materials over the past 12 months.

Challenges to future increases in recycled materials usage include overcoming technical concerns such as durability and potential contamination; constrained supply availability; limited data that traces origins; and international regulations that may inhibit cross-border shipments. “Addressing these takes a collective response,” Apple said.
