Earth Day falls on 22nd April, and to mark this important date, Do You Really Know is rerunning a series of episodes about environmental issues affecting our planet. Let's take a refresher on some of the terms and concepts you need to be familiar with, in order to understand climate change. Happy listening!

What is carbon footprint?

Postponed for a year because of Covid-19, COP26 meets in Scotland from October 31 to November 12. A carbon footprint is the total amount of greenhouse gases emitted by the energy and raw material consumption of a person, organisation or event. It is measured in the volume of CO2 emitted. Per capita emissions in the USA are estimated at around 16 tons per year. That includes CO2 produced directly by an individual’s household, and emissions created by products they consume. The rough split is 70/30 between the two.

It’s a bit of a vague calculation though, isn’t it? But it must be pretty darn difficult to place an accurate value on the impact of all living beings in a country? How can I reduce my own footprint? In under 3 minutes, we answer your questions!
