Earth Overshoot Day is the day in the year when we have used more of Earth’s resources than the Earth can regenerate in the whole year. It occurs earlier and earlier every year mainly because of our growing CO2 emissions.
Andrew Simms originally conceived the concept of Earth Overshoot Day while working at the UK think tank New Economics Foundation. Earth Overshoot Day is calculated by Global Footprint Network and is a campaign supported by dozens of other nonprofit organizations.
Each of us can take steps to reduce our carbon footprint and so move the date of Earth Overshoot Day later rather than earlier. For ideas see www.overshootday.org
