What is a Carbon Footprint?

Your carbon footprint is the total amount of greenhouse gasses (GHGs) that you directly or indirectly produce in your lifetime. Take the Environmental Protection Agency’s Carbon Footprint Quiz, Nature Conservancy’s Quiz, or our own Ecological Footprint Quiz to find out just how many pounds of carbon dioxide that you produce and how you can decrease it. 

What are greenhouse gasses and why are they important? 

Greenhouse gasses, such as carbon dioxide and methane, trap heat in the atmosphere. They then release that heat back down to Earth. This environmental process is necessary for our survival, for Earth would be too cold to live on without it. However, in recent centuries, we have been emitting excessive amounts of carbon dioxide, and other GHGs, into the atmosphere. This huge influx of greenhouse gases is causing climate change.  

What am I doing in my daily life that produces GHGs, and how can I produce less?

The biggest source of greenhouse gasses in the U.S. is from transportation. It made up 28% of all greenhouse gasses emitted by the United States in 2018The second biggest source is electricity.

Climate change, a direct cause of excessive greenhouse gas emissions, will continue to have disastrous impacts on our society if we do not make a changeSea level rise, an increase in heat- related deaths, increased extreme weatherand ocean acidification are just some examples of the effects of climate change. Decreasing your personal carbon footprint will help mitigate climate change and its impacts
