You’ve got the questions, we’ve got the answers!

Actually, the opposite is true. Studies show that people who offset their carbon emissions are more climate friendly in other parts of their lives, too. That makes sense: When you’re personally invested in a cause, you want it to succeed.

We wrote a full blog post about this here. Read on for a tl;dr:

We only choose projects from the most impactful climate solutions worldwide, as identified by Project Drawdown, a nonprofit that conducts rigorous assessments of climate solutions and represents a leading resource in our field.

Also, all our projects must meet the highest international quality standards for certified carbon offsetting, and are verified through the Verified Carbon Standard, or the Gold Standard developed by WWF and other NGOs.

On top of that, all our projects provide at least three additional benefits to their local communities that align with the UN Sustainable Development Goals. These range from combating poverty, protecting endangered species, empowering female entrepreneurship, or advancing access to healthcare and education.

Klima is a social startup from Berlin, with a growing team of mission-driven designers, engineers, marketeers, and changemakers from five continents. Together, we’re united by one goal: making a measurable dent in the fight against global warming. 

Klima was founded in 2019 by Markus Gilles, Jonas Brandau, and Andreas Pursian-Ehrlich. They first met 10 years ago while working for different sustainable development NGOs and have since founded several tech-for-good companies, aimed at promoting civil discourse, quality journalism, and women’s empowerment. They started Klima to commit their resources to the most important challenge of our lifetime — and empower others to do so as well.

We calculate your footprint based on precise lifestyle questions that we combine with a national baseline of the country you live in. This gets us a close estimate based on your individual circumstances and personal choices. 

All questions are designed for intuitive responses via a multiple-choice chat interface, and the setup takes about three minutes. Examples of questions include “What best describes your diet?”, “What kind of shopper are you?”, or “How many flights do you take per year?”

After the initial setup is complete, you can customize your footprint further by using the advanced calculator mode. This offers 38 additional questions for more granular results.

There is no single solution to stop climate change — it’s going to take creativity, dedication, and action from us all. Carbon offsetting is one big piece of that puzzle.

While political regulation or cleantech inventions can take decades to be implemented, offsetting allows you to take your footprint off the planet. right. now. That’s a big advantage and it’s why Klima starts here and then shares ways to reduce your footprint further.

We encourage the Klima community to adopt climate-healthy lifestyles and support political action to fight climate change. It's crucial that we work on every front, pushing for short-term and long-term solutions that make our societies carbon neutral.
