We are

From our own experience, we know how complex and time-consuming it is to find sustainable solutions for your own company. From green hosting and sustainable electricity to industry-specific, innovative technologies. But companies in particular can make a major contribution to climate change.

With this challenge and over a long journey THE CLIMATE CHOICE was born.

Our Mission

We enable every company to successfully implement climate transformation and reduce 50% of supply chain emissions by 2030.

Our Vision

As Climate Champions, companies make every procurement decision as a climate decision.

Our actions, transparency & network

THE CLIMATE CHOICE also does not want to release even more emissions, but rather prevent them as far as possible and operate in a climate-neutral manner. We want to save more emissions than we release. To this end, we use solutions that allow us to do this from the very beginning. We host this website at biohost.de, use windcloud.de for our software, we use GLS Bank for finances, we use green electricity from Naturstrom.de in our home office and use co-working offices that are equipped to be as sustainable as possible, we cover all distances in Berlin by bike, we travel in Germany only by train, we pay attention to predominantly vegetarian, regional and seasonal food and we offset our footprint according to the guidelines of Leaders for Climate Action. Nevertheless, we are only at the beginning of our journey and will keep you informed about our progress towards becoming a “climate positive” company.

We are part of several entrepreneurial networks and initiatives for climate action in business. Among others, we are allowed to support Leaders for Climate Action, Entrepreneurs4Future as well as the EntrepreneursPledge and are members of the German Sustainable Business Association. We are also particularly pleased to be honorary members of the Impact Hub Leipzig!
