GM Hits 100% Renewable Energy Target, First Among US Makers

General Motors (GM) has become the first US automaker to secure enough renewable energy to match 100% of its electricity use across all its facilities in the country, a milestone that could have significant implications for the company's supply chain and broader automotive value chains.

The announcement was made by Cassandra Garber, Chief Sustainability Officer at General Motors, during a fireside chat with Sustainability Magazine's Editor-in-Chief Steven Downes at Sustainability LIVE: The US Summit in Chicago. The achievement underlines the company's commitment to its long-term goal of manufacturing 100% electric vehicles.

Writing in a GM blog post, Cassandra explains that managing energy use has become a business necessity rather than simply a corporate reporting exercise. The company reached the milestone in 2025, positioning itself as a leader among US automakers in renewable energy adoption.

Supplier engagement and value chain transformation

The renewable energy achievement forms part of a broader strategy to decarbonise GM's entire value chain, with the company now actively pushing its supplier network to follow its lead. Cassandra reveals that GM is sending a clear signal to suppliers and partners to join the decarbonisation journey by enrolling in programmes like Transform: Auto, which drives renewable energy adoption through the automotive value chain.

This supplier engagement strategy could reshape procurement practices across the automotive sector, as manufacturers increasingly factor environmental performance into their sourcing decisions. Cassandra notes that the zero-emissions journey starts before an electric vehicle customer ever hits the accelerator, highlighting the importance of upstream emissions reduction.

The company's approach to supplier decarbonisation could create ripple effects throughout the supply chain, potentially requiring tier-one and tier-two suppliers to make similar renewable energy commitments to maintain their relationships with the automaker.

Operational impacts and infrastructure investment

GM's renewable energy programme has delivered measurable operational and economic impacts. Globally, the company matched 70% of its electricity usage with renewables in 2025, nearly double its 2023 level, thanks to new projects in Mexico and Brazil. The company has reduced operational emissions across Scopes 1 and 2 by 52% since 2018.

The domestic renewable energy investments have generated approximately US$1.9bn in GDP impact since 2015, with projects contracted through 2026 adding a further US$333m. According to Cassandra, projects GM has invested in also support an average of 1,500 construction jobs per year across states, including Michigan, Texas, Ohio, Arkansas and Illinois, while funding rural schools and emergency services through local taxes.

In 2025, GM's renewable sources comprised clean energy utility programmes at 40%, virtual power purchase agreements at 37%, unbundled renewable energy credits at 14%, default delivered renewable energy at 8%, and onsite generation and landfill gas at 1%.

Managing energy across regional grids

Cassandra explains that the company's annual energy "matching" works similarly to a bank account. GM contracts for enough clean energy from projects like Newport Solar and Hilltopper Wind Farm to equal every kilowatt-hour it pulls from the grid. As GM ensures a 1:1 match for all electricity used by its US operations, the company prioritises projects on the same regional grid as its facilities.

This approach to energy procurement offers several operational advantages. Long-term renewable contracts insulate GM from energy market volatility, providing price stability for operations. More clean energy on the grid could mean a more dependable system for all users, while reduced reliance on foreign energy imports strengthens local communities.

Cassandra concludes that achieving GM's renewable goal in the US and making continued progress internationally proves that decarbonising operations and driving economic growth are not in conflict. "GM is building the vehicles — and the energy systems — that will help us all enjoy an all-electric future," she said.
