Your footprint explained
Your footprint is calculated in CO₂e (carbon dioxide equivalents) using around 30 public data sources.
The science is grounded in the Exponential Roadmap, which sets a personal climate budget of 2 tonnes of CO₂e per year to keep global warming below 1.5°C. The good news? About 80% of your footprint is within your control, and we show you exactly where.
We look at emissions across three areas of your life: housing, travel, and consumption.

I am a high school Biology teacher, so I LOVE to use this program with my students when we discuss sustainability, pollution, and the Biogeochemical Cycles! The students love seeing their impact and working together to come up with their solutions to make the world a cleaner place!

This measurement tool has completely changed how I view my life and business decisions. I can now track how my choices are having a positive effect on my footprint, and it drives me to do more.

I'm proactive when considering the effect my life has on my granddaughter's future. I'm 79 but she is only 13 so I won't be around for much of her adult life and it's important to me to do my best for her future. Completing the Climate Hero carbon calculator gives me an opportunity to see how the way I live my life compares to others and how I can continue to improve my carbon footprint.

Was looking for a new carbon calculator to see my footprint 5 years later, really simple and quick to do. Alongside actions I can do, for the carbon I cannot address there is an easy carbon offset option to help feel part of doing my bit and set up a monthly subscription.

Personal carbon footprint was easy to assess. I liked the second part where you set goals to reduce your CF. Great to have something to measure. Keep up the good work - it is so important for each of us to do our share of reducing CO2 emissions
