MARYSVILLE - Seven Honda U.S. manufacturing plant locations have earned the 2025 U.S. Environmental Protection Agency (EPA) ENERGY STAR certifications for Outstanding Energy Efficiency, company officials announced earlier this month.
Locally, the Marysville and East Liberty Auto Plants also earned a unique distinction for the EPA certification - receiving the designation for the 20th consecutive year since the EPA Industrial Program’s inception in 2006.
In addition, the Anna Engine Plant garnered its eighth award and the Honda Transmission Plant in Russells Point received its sixth award.
ENERGY STAR certification is awarded to plants in the top 25th percentile of all plants in the nation with regard to energy performance. The award is based on energy used per unit produced.
Also among Honda’s U.S. plants earning ENERGY STAR certification for 2025 include:
Indiana Auto Plant achieved certification for the 14th year in a row.
Alabama Auto Plant’s engine plant received its seventh award.
Honda Transmission Plant-Georgia earned its sixth award.
Honda of Canada Mfg. also earned its seventh awards for its auto and engine plants.
The EPA certification demonstrates Honda’s dedication to reduce energy use and greenhouse gas emissions.
“The ability of Honda to earn U.S. EPA Energy Star certification is based on the continuous efforts of our associates in reducing energy use at our production facilities in America,” said Honda Environmental Department Manager Jeff Waid.
“In addition to energy efficiency, we are very proud of our commitment to minimize waste and water use as part of our comprehensive approach toward reducing environmental impact.”
Building on the company’s longstanding environmental commitment, Honda established its Green Factory initiative in 2021 to address the environmental impacts of manufacturing, including water and energy use, waste, and emissions at its facilities.
New efforts include:
Repairing compressed air leaks;
Installing a solar walkway for pedestrian travel;
Paint oven modifications to reduce natural gas usage;
Replacing gas heat sources with electric heat pumps;
Recovering and utilizing waste heat to reduce natural gas usage;
Paint Reverse Osmosis water recovery;
Cooling tower upgrades and boiler control upgrades.
Honda has also completed many decarbonization projects at its manufacturing facilities.
Recent electrification projects include the implementation of: electric boilers, electric arc furnace, Electric Regenerative Thermal Oxidizer (RTO), electric forklifts, and EV charging stations.
Additionally, Honda has implemented carbon reduction initiatives by shifting to low-carbon energy sources and covering more than 80 percent of the electricity used in its North American manufacturing operations through long-term virtual power purchase agreements (VPPAs) for renewable wind and solar power.
ENERGY STAR was introduced by the EPA in 1992 as a voluntary, market-based partnership to reduce greenhouse gas emissions through energy efficiency. To date, tens of thousands of buildings and plants across all 50 states have earned the ENERGY STAR.
