From Due Diligence to Circularity: Why America must Follow the European Union’s lead on EV Batteries
By Lakshita Dey
The electric vehicle (EV) revolution promises a cleaner future but has exposed a new environmental and ethical dilemma. Essential battery materials, lithium, cobalt, and nickel, are mined under conditions frequently criticized for environmental harm and human rights violations.[1] The mining and refining of these raw materials results in toxic chemicals from lithium extraction and widespread long-term pollution from nickel production.[2] Further, concerns regarding poor working conditions, child labor, and human rights violations, particularly in the cobalt mining in the Democratic Republic of the Congo, highlight the need for reform.[3] Addressing these challenges requires a legislative response that mandates transparency in sourcing and extraction of these raw materials. This solution compels the creation of a circular battery economy—a regenerative system that minimizes resource input and waste.[4]
Due diligence laws serve as the global forefront for mitigating these risks. Laws like the European Union’s (EU) due diligence requirements ensure that companies do not contribute to conflict and respect the environment and human rights.[5] These powerful laws harness the vast consumer market to ensure global accountability for environmental and social impacts of the battery value chain.[6] The regulations adopt a value chain[7] perspective to address all activities, from the raw materials stage to the end-of-life of a product. These measures ensure that products are sourced and manufactured in a sustainable manner and contribute to curbing carbon emissions on a global level.[8]
The EU’s Batteries Regulation compels any company placing batteries on its market to comply with a set of requirements spanning the entire battery life cycle.[9] This is not a passive request; it is a legal obligation that includes due diligence policies to identify, assess, and mitigate social and environmental risks across the entire supply chain. Additionally, the regulation introduces requirements such as waste collection and recycling for circularity, carbon footprint declaration and minimum performance for sustainability, and battery passports[10] to support traceability.[11]
Moreover, Extended Producer Responsibility provisions bolster the comprehensive framework of due diligence laws by increasing waste collection and recycling.[12] Specifically, this mechanism establishes a division of responsibility that extends to the post-consumer phase of the product life cycle.[13] The legal emphasis on due diligence effectively formalizes the concept of Corporate Social Responsibility, highlighting the profound responsibility business and industry must assume to contribute to sustainable development and inclusive human well-being.[14]
Relying solely on due diligence laws, however, fails to solve the long-term resource problem. An environmentally friendly battery future demands legal instruments that alter how batteries are designed, manufactured, and used, and disposed of. The legislature must ultimately focus on advancing a circular economy for batteries through aggressive, product-based mandates. It creates value that is not only economic but also environmental and societal by designing waste out of the system and decoupling economic activity from the consumption of finite resources.[15]
First, the legislature must create an economic pull for recycled materials. The EU Batteries Regulation creates an economic pull by mandating minimum percentage thresholds[16] for recycled content in new batteries.[17] These thresholds establish an obligation for manufacturers to incorporate a minimum percentage of these materials, sourced from recycled waste, into the composition of new batteries.[18] Recycling batteries is a promising solution to resource scarcity and supply chain risks. This process recovers valuable materials, creating a circular economy.[19] Recovering these valuable materials makes a circular system a more economically viable alternative to rising raw material costs. Recycling is key to providing a more reliable and affordable supply of materials and creating a market demand for secondary materials.
The American government could create a similar market pull by mandating minimum recycled content quotas for battery materials sold or manufactured in the U.S. Legally, this could be enacted using Congress’s Commerce Clause[20] authority to regulate interstate and international trade,[21] or by the Environmental Protection Agency (EPA) using its powers under statutes like the Resource Conservation and Recovery Act.[22] The mandate could initially target government-funded projects to establish demand for recycled materials. This leverages federal spending power to create a “captive market,” thereby mitigating the initial risk for recyclers and manufacturers.[23] Requirements could then be expanded to the entire market through nationwide regulations, modeling the EU’s approach.
Second, the government should promote technological advancements that enhance design and durability, extend the battery’s useful life, and facilitate its reuse. EU regulation requires EV batteries to be easily removable and replaceable by qualified professionals.[24] This simple legal requirement prevents the premature scrapping of entire vehicle components due to a single battery issue.[25] More significantly, it unlocks the second-life market, allowing used EV batteries to be repurposed for stationary energy storage.[26]
The U.S. legislature can promote similar technological advancements by requiring standardized battery modules. This would mandate EV batteries to be easily accessible for removal and replacement, providing documentation to third-party professionals.[27] Congress could create a dedicated “right to repair” framework for EV batteries, drawing on the Commerce Clause to set national manufacturing and warranty standards.[28] This would facilitate reuse in a second-life market, effectively extending the battery’s utility, and delaying the need for recycling.
Third, the legislature should utilize information transparency as a legal tool for environmental performance. For example, the EU “Battery Passport” is a digital record containing the battery’s composition, state of health, and manufacturing carbon footprint.[29] Requiring manufacturers to declare a battery’s carbon footprint creates a performance standard. The digital traceability provides data for recyclers to efficiently process batteries. The record also gives consumers and regulators a clearer picture of a product’s true environmental cost.[30] This disclosure paves the way for future legislation to impose mandatory maximum CO2 equivalent limits, driving companies toward low-carbon manufacturing processes.
To adopt the EU’s transparency mandate, the U.S. can leverage existing legal authority. The Inflation Reduction Act (IRA) provides a foundation, as its consumer tax credits require proof of EV battery sourcing.[31] A mandatory digital tracing system is the most effective way to ensure compliance with these IRA mineral requirements. Additionally, a mandate for product-level carbon disclosure can be rooted in the power of the EPA. Requiring manufacturers to disclose a battery’s carbon footprint establishes a baseline that allows for future laws to mandate carbon limits and incentivize low-carbon production.[32]
Ultimately, creating a truly circular battery economy is the essential next step for a sustainable EV revolution. While domestic due diligence laws provide a critical foundation by addressing immediate supply chain ethics, they are only a partial solution. An aggressive, product-based legislative agenda is essential for long term environmental and resource security. By enacting policies that mandate design choices, set recycled content floors, and enforce digital transparency, the American government can mirror and enhance the EU’s comprehensive framework. Only by leveraging the full power of law to govern the entire life cycle can the EV revolution deliver on its promise of a sustainable future.

The concept of ‘second life’ applications for electric vehicles has gained global traction, aligning with the principles of a circular economy. By extending the lifespan of lithium-ion batteries beyond automotive use, we not only reduce the demand for raw materials, but also optimize the value chain of energy storage.”
