With Klima, a carbon neutral life has never been simpler. Calculate your carbon footprint and neutralize 100% of your CO2 emissions in just three minutes. How? By funding science-based climate projects that capture or prevent the same emissions elsewhere. Next, learn how to shrink your own footprint sustainably and watch your positive impact grow.

It’s easy to measure the climate impact of your lifestyle with our natural language chat tool. Just answer a few quick questions to learn how much CO2 you emit each year.

Support world-class climate projects that capture CO2 and neutralize your footprint with an affordable monthly subscription. You can choose between tree-planting, solar power, and social impact projects — or support all three! All projects are independently measured, verified, and monitored by the highest international standards.

Enjoy a carbon neutral life and celebrate your personal milestones. Our real-time tracker shows you the impact of your offsets on the ground. Share your achievements with the world and inspire your friends!

Offsetting is a smart choice — and we even help you go beyond. Klima helps you reduce your overall footprint sustainably, with personalized tips, ideas, and inspiration from our Climate Checklist. As you shrink your footprint, so does the cost of your monthly offset. It’s a win-win!

Join the climate-conscious movement and offset your footprint with Klima.

Klima is free to download. After calculating your personal carbon footprint, you can offset your emissions by funding on-the-ground climate projects with a monthly offset plan. The price of your offset plan is personalized and based on your footprint calculation. If you decide to offset, payment for the total monthly fee will be charged through the payment method you selected (e.g. Apple Pay, or Credit Card) at the time you confirm your purchase. Once purchased, refunds will not be provided for any unused portion of the term. Offset plans renew automatically unless cancelled at least 24 hours prior to the end of the monthly period. There is no increase in price when renewing. You can manage your plan and disable the automatic renewal at any time via the app settings.

Great approach and execution

This is exactly what we need-a streamlined approach to estimate your carbon footprint that allows regular people to get involved without having to be high powered control freaks.

I was a bit worried about how they would deal with offset payments. After looking around though, I feel pretty comfortable with their strategy: most $ (70%) goes directly to offsetting projects while 20% goes to funding “impact marketing” and the final 10% is for a service fee. Initially weird but now I does make sense to me as if done well, engaging outreach/marketing really will help get more and more people involved. Makes sense, is sorely needed (ain’t nuthin’ gonna happen on its own). I’ll hover in undecided land for a while, but I like the idea of offsetting my (and my family’s) carbon footprint via Klima!

Excellent interface! Easy to go carbon neutral and track impact.

This app is truly well designed. It allows you to get an estimate of your carbon impact and immediately go carbon neutral. It’s really cool because you get to track how much solar energy you’re producing and how many trees have been planted. You have options on which methods you use so if you’d just prefer to only plant trees that’s an option too! I highly recommend this app!

Ecologi is better

I like the idea as someone a few years into my sustainability journey, but I think Ecologi is better (even though they don’t have an app yet) because they let you choose where you plant your trees, there’s different projects every month, and you can offset your pets and family members’ emissions. You can also add additional trees/C02 offsets mid-month and they have gift packages as well. Ecologi also has business plans (because while the consumers can help, at the end of the day 100 corporations are responsible for 70% of emissions.)

Not sponsored, just some thoughts for improvement. Ecologi is Uk based and doesn’t have an app, so for some people this might work better.
