What Is Climate Change?
Many of our daily activities contribute to climate change. Using energy in our homes and offices or driving a car generates greenhouse gas emissions, such as carbon dioxide (CO2). These greenhouse gases act like a blanket, trapping heat near the Earth's surface and warming the planet.
If the Earth's warming continues, scientists predict potentially extreme climate changes—causing more frequent and intense heat waves, rising sea levels affecting coastal areas, and other serious impacts.
But there is good news: working together, we can make a difference.
Calculate Your Carbon Footprint
Your "carbon footprint" is a measure of your impact on the environment, in terms of the carbon dioxide emitted as a result of your daily activity.
Use this calculator to estimate your carbon footprint from the energy you use and the vehicle you drive—and learn how PG&E can help you reduce your footprint.

If you are working to estimate your company's or community's carbon footprint, PG&E provides a GHG Emission Factor Info Sheet (PDF, 111 KB) to assist with the preparation of voluntary greenhouse gas inventories and climate action plans.
