Businesses account for 50% of U.S. energy consumption. Switching to renewable energy significantly reduces greenhouse gas emissions and is an effective strategy for combating climate change. Buying certified offsets can help reduce your contribution to climate change for emissions you can't reduce further, like those from onsite heating and vehicles.
