Transforming a company

The energy transformation at General Motors is the first part of the company’s bold vision of zero crashes, zero emissions, and zero congestion. GM is a big energy purchaser but procurements account for only 1% of the company’s carbon emissions. Scaling zero emissions efforts requires the transportation industry’s transformation to electric vehicles. GM aims to be an all-electric vehicle manufacturer of all its light-duty vehicles by 2035. That goal requires the company, which has built ICE vehicles for the last 100 years, to transform into an all-electric vehicle manufacturer in just twelve years.

Moving transportation to decarbonization

How can the vehicle industry truly achieve zero emissions? Many changes will have to occur on the state and federal levels. Changing the car industry goes well beyond General Motors and will require everyone in the entire industry. It is critical to work closely with the supply chain to move it down the path of decarbonization. If the production of supplies is interrupted, vehicles can’t be made.

GM’s renewable energy U.S. footprint is about 3.5 terawatt hours, and the company has accumulated about 1500 megawatts of renewables across projects over several states and RTOs. The company looks specifically for projects located within its manufacturing footprint. GM has been working with utilities to create green tariff programs and to find ways to expand those programs beyond just General Motors.


Energy Solutions

GM recently announced the energy side of its business is enabling solutions in the whole energy ecosystem. Matching these renewable solutions with manufacturing will be critical to decarbonizing utility and transportation and ultimately driving a more resilient grid. As GM grows its EV portfolio, the company needs to ensure that demand matches the generation portfolio and continues to scale.
