Why We Built Carbon Simple
There are hundreds of carbon footprint calculators on the internet. Some are backed by governments, others by NGOs, universities, or corporations. So why build another one?
The Problem with Existing Tools
After using and reviewing dozens of carbon calculators, we noticed three recurring problems:
1. They Make You Feel Guilty, Not Empowered
Many calculators end with a shocking number — "You emit 12 tonnes per year! You need to plant 540 trees!" — without explaining what that number means, how it compares to averages, or which specific actions would have the biggest impact. The result: anxiety without direction.
2. They Treat All Actions as Equal
Most calculators give you a generic list of tips: "Drive less. Eat less meat. Switch to LED bulbs." But switching to LED bulbs saves about 15 kg CO₂e per year while switching from beef to chicken saves 500 kg. These actions aren't even close to equal — and the calculator doesn't tell you that.
3. They Hide Their Math
Where do the numbers come from? How is a 2,000 km flight calculated? What emission factor is used for electricity? Most calculators don't say. You enter your data, get a number, and have no way to verify whether it's reasonable.
What We Do Differently
Carbon Simple was built around three principles:
Data First
Every number on this site — every emission factor, every comparison, every recommendation — comes from peer-reviewed research or official data sources. We cite our sources. We show our formulas. If you want to check our math, you can.
Our Emission Factors Reference lists every coefficient we use, with its source. Our calculation method articles walk through the formulas step by step.
Impact-Ranked Actions
We don't just give you a list of tips. We rank them by actual CO₂ reduction potential. Our 50 Most Effective Actions article tells you exactly how many tonnes each action saves — so you can focus on what matters most.
The result: a 30-minute read that changes your behavior more than a 3-hour guilt trip.
Practical, Not Preachy
We write for real lifestyles. Not everyone can install solar panels or buy an electric car. Our guides are organized by situation: apartment dwellers, office workers, people who like food. We don't moralize — we calculate.
Our Goal
We want Carbon Simple to be the site you visit when someone asks "Does my individual action actually matter?" and you want to give them a real answer — with numbers.
The average global per capita emission is about 4.7 tonnes CO₂e per year. The Paris Agreement target requires getting that below 2.3 tonnes by 2030. That's a big gap, but the data shows which actions close it fastest.
That's what Carbon Simple is for.
What's Next
We're building out our content library, improving the calculator, and working on new features. Check our latest update to see what's new.
