What is "Carbon Neutral"?
Every time we travel or turn on our computers, we add
to the atmosphere. Most of the energy we use comes from oil, coal, and gas. Solar and wind power does not cause climate change
. But it often costs more.
Being "carbon neutral" means removing as much carbon dioxide from the atmosphere as we put in. How can we remove carbon dioxide from the atmosphere? One way is to buy "carbon offsets". This supports projects like a wind farm or solar park. It helps make clean energy cheaper. It removes future greenhouse gases to make up for our energy use today.
Start with the Carbon Calculator link below. Find out how much carbon dioxide comes from the things we do every day. Then explore the list of projects that provide Carbon Offsets. We are on our way to being "carbon neutral"!
