For millions of consumers, the sustainability scheme stickers found on everything from bananas to chocolate bars and wooden furniture are a way to choose products that are greener and more ethical than some of the alternatives.

Inga Petersen, executive director of the Global Battery Alliance (GBA), is on a mission to create a similar scheme for one of the building blocks of the transition from fossil fuels to clean energy systems: batteries.

“Right now, it’s a race to the bottom for whoever makes the cheapest battery,” Petersen told Climate Home News in an interview.

The GBA is working with industry, international organisations, NGOs and governments to establish a sustainable and transparent battery value chain by 2030.

“One of the things we’re trying to do is to create a marketplace where products can compete on elements other than price,” Petersen said.

Under the GBA’s plan, digital product passports and traceability would be used to issue product-level sustainability certifications, similar to those commonplace in other sectors such as forestry, Petersen said.

Managing battery boom’s risks

Over the past decade, battery deployment has increased 20-fold, driven by record-breaking electric vehicle (EV) sales and a booming market for batteries to store intermittent renewable energy.

Falling prices have been instrumental to the rapid expansion of the battery market. But the breakneck pace of growth has exposed the potential environmental and social harms associated with unregulated battery production.

From South America to Zimbabwe and Indonesia, mineral extraction and refining has led to social conflict, environmental damage, human rights violations and deforestation. In Indonesia, the nickel industry is powered by coal while in Europe, production plants have been met with strong local opposition over pollution concerns.

“We cannot manage these risks if we don’t have transparency,” Petersen said.

The GBA was established in 2017 in response to concerns about the battery industry’s impact as demand was forecast to boom and reports of child labour in the cobalt mines of the Democratic Republic of the Congo made headlines.

The alliance’s initial 19 members recognised that the industry needed to scale rapidly but with “social, environmental and governance guardrails”, said Petersen, who previously worked with the UN Environment Programme to develop guiding principles to minimise the environmental impact of mining.

Digital battery passport

Today, the alliance is working to develop a global certification scheme that will recognise batteries that meet minimum thresholds across a set of environmental, social and governance benchmarks it has defined along the entire value chain.

Participating mines, manufacturing plants and recycling facilities will have to provide data for their greenhouse gas emissions as well as how they perform against benchmarks for assessing biodiversity loss, pollution, child and forced labour, community impacts and respect for the rights of Indigenous peoples, for example.

The data will be independently verified, scored, aggregated and recorded on a battery passport – a digital record of the battery’s composition, which will include the origin of its raw materials and its performance against the GBA’s sustainability benchmarks. 

The scheme is due to launch in 2027.

A carrot and a stick

Since the start of the year, some of the world’s largest battery companies have been voluntarily participating in the biggest pilot of the scheme to date.

More than 30 companies across the EV battery and stationary storage supply chains are involved, among them Chinese battery giants CATL and BYD subsidiary FinDreams Battery, miner Rio Tinto, battery producers Samsung SDI and Siemens, automotive supplier Denso and Tesla.

Petersen said she was “thrilled” about support for the scheme. Amid a growing pushback against sustainability rules and standards, “these companies are stepping up to send a public signal that they are still committed to a sustainable and responsible battery value chain,” she said.

There are other motivations for battery producers to know where components in their batteries have come from and whether they have been produced responsibly.

In 2023, the EU adopted a law regulating the batteries sold on its market.

From 2027, it mandates all batteries to meet environmental and safety criteria and to have a digital passport accessed via a QR code that contains information about the battery’s composition, its carbon footprint and its recycling content.

The GBA certification is not intended as a compliance instrument for the EU law but it will “add a carrot” by recognising manufacturers that go beyond meeting the bloc’s rules on nature and human rights, Petersen said.

Raising standards in complex supply chain

But challenges remain, in part due to the complexity of battery supply chains.

In the case of timber, “you have a single input material but then you have a very complex range of end products. For batteries, it’s almost the reverse,” Petersen said.

The GBA wants its certification scheme to cover all critical minerals present in batteries, covering dozens of different mining, processing and manufacturing processes and hundreds of facilities.

“One of the biggest impacts will be rewarding the leading performers through preferential access to capital, for example, with investors choosing companies that are managing their risk responsibly and transparently,” Petersen said.

It could help influence public procurement and how companies, such as EV makers, choose their suppliers, she added. End consumers will also be able to access a summary of the GBA’s scores when deciding which product to buy.

US, Europe rush to build battery supply chain

Today, the GBA has more than 150 members across the battery value chain, including more than 50 companies, of which over a dozen are Chinese firms.

China produces over three-quarters of batteries sold globally and it dominates the world’s battery recycling capacity, leaving the US and Europe scrambling to reduce their dependence on Beijing by building their own battery supply chains.

Petersen hopes the alliance’s work can help build trust in the sector amid heightened geopolitical tensions. “People want to know where the materials are coming from and which actors are involved,” she said.

At the same time, companies increasingly recognise that failing to manage sustainability risks can threaten their operations. Protests over environmental concerns have shut down mines and battery factories across the world.

 “Most companies know that and that’s why they’re making these efforts,” Petersen added.
