How ENERGY STAR Helps Fight Climate Change

Climate change is a real and urgent challenge affecting people and the environment worldwide. Heat-trapping greenhouse gases are now at record-high levels in the atmosphere, compared with the recent and distant past. Both human and natural causes contribute to climate change.

EPA’s ENERGY STAR program helps to protect our climate by reducing energy use—through both energy efficiency and efficient electrification. Reducing energy use cuts down on the greenhouse gas emissions (GHGs) that cause climate change, either by reducing the amount of fossil fuels burned at power plants or by reducing the amount of fuel—such as natural gas—that is burned on-site at homes, buildings, and industrial plants.

So what can you do? ENERGY STAR offers tips and product information to help you do your part in protecting the environment, your family, and your community from the effects of climate change, now and in the future.
