We who reach our climate goals with The Carbon Contract:

ElinderSten
It is thanks to the architects at ElinderSten – their dedication and commitment to achieving their climate goals through concrete, local, and credible actions – that The Carbon Contract became a reality.
ElinderSten works actively to reduce its climate footprint, and through the purchase of Swedish carbon credits, they are already reaching their goals. Their vision, “Connecting Places to People”, truly resonates with our own. Because The Carbon Contract is all about creating new connections – for example, between the city’s architects and the countryside’s biochar producers.
With collaborations like these, we will rise to the climate challenge together!

ISOS Partnership
ISOS Partnership supports governments and public authorities in developing strategies and policies in the UK and internationally.
They know that development and climate goals aren’t achieved through empty words. It takes real actions and collaborations built on trust. Through The Carbon Contract, ISOS reaches its climate goals by supporting activities that have been challenging to realise in London – but are made possible through biochar on the Swedish countryside.
We share the same conviction: that the solutions to the climate crisis require collaboration across borders.

Swedish soil and property companies
In many cases, carbon credits are sold separately from the biochar that generates them — but not always. We’re truly grateful to all the Swedish agricultural, construction, and property companies that choose to purchase their biochar together with certified carbon credits. By using biochar themselves, they directly reduce the climate impact of their construction projects, while also creating multiple added benefits beyond the carbon credits: more greenery in our cities, cleaner stormwater, and greater resilience to flooding and drought on farmland.
These co-benefits make biochar an unbeatable way to create meaningful, verifiable carbon credits!

EcoTopic
The consultancy firm EcoTopic has worked with both the production and use of biochar for many years. They believe in leading by example — doing the right thing themselves before pointing at others — and naturally, they reach their climate goals through The Carbon Contract.
“Cleaning your own doorstep first” is also one of the core principles behind The Carbon Contract: to create certified carbon credits for Swedish companies, here in Sweden.
