ENVIRONMENT

The largest environmental impact of our manufacturing results from the use of natural gas and production of electricity, which creates CO₂ emissions. Honda is decreasing its CO₂ generation by reducing energy usage, increasing energy efficiency of processes, installing carbon neutral equipment when equipment is at end of life, and using clean energy. Some of our efforts include:

Additionally, Honda mass production and manufacturing facilities in the U.S. continue to lead the industry in energy efficiency. All Honda U.S. and Canada auto plant locations earned the 2024 U.S. Environmental Protection Agency (EPA) ENERGY STAR Certificate for Outstanding Energy Efficiency.

Reduce Industrial Water Intake  
We make every effort to use as little water as possible in our product development and manufacturing efforts. We have set a goal to achieve zero industrial water intake by 2050. Additionally, we’ve implemented programs to effectively treat all wastewater prior to its discharge to municipal treatment plants.

Honda Supplier Sustainability Excellence Program
Building a responsible supply chain is an ongoing effort. That’s why we work closely with our suppliers to improve their sustainability performance across seven key pillars: Compliance and Ethics, Diversity, Environment, Governance, Health and Safety, Social Responsibility, and Trade Compliance. 

For environmental sustainability, we focus on enhancing biodiversity, conserving water, and reducing CO₂ emissions. We set requirements and share best practices with our suppliers to make a meaningful impact together.

We’ve collaborated with 13 other automakers to develop the Automotive Industry Guiding Principles and Practical Guidance Document to achieve supply chain excellence, innovation, and performance in a sustainable manner. The auto industry supply chain has a high degree of complexity, so these guidelines allow us to work together to attain the highest standard when it comes to the environmental performance of our supply chain.
