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.
