General Motors has cut energy intensity at 30 North American plants by an average of 25—equivalent to the emissions from powering 97,000 US homes—to meet the US Environmental Protection Agency’s (EPA) Energy Star Challenge for Industry.
Collectively, the manufacturing facilities avoided more than 778,380 metric tons of greenhouse gases. It would require the planting of 20 million trees that grow for 10 years to mitigate the same amount. The efforts saved GM $50 million in energy costs.
EPA’s program challenges manufacturing companies to reduce greenhouse gas emissions by improving their energy efficiency by 10% within five years. The GM plants agreed to establish an energy intensity baseline normalized by production volume. They set a 10% improvement goal, implemented energy efficiency projects, tracked energy use and verified savings.
