We drive value to planet-positive projects by creating easy-to-use open source carbon retirement tools available in the public domain.

Make Devcon VI Climate Friendly
We helped to make Devcon VI climate friendly. The 228 individual addresses which contributed in the dApp helped to retire (offset) over 400 tons of carbon by supporting a carbon project in Peru. Not only did the participants help the climate, but they also got a POAP or even a second one for participating.The POAPs that were distributed to participants and votersStorydisCarbon started as a project from the ETHAmsterdam hackathon in spring 2022.

All Flight Emission Estimators Are Wrong...
…but some are usefulA benchmark of readily available flight emission estimators.All models are wrong but some are useful.George Box (Wikipedia) All flight emission estimators have to simplify the complexity of the real world in order to estimate a carbon footprint incurred by air travel. Some make more assumptions, some less. In this post, we discuss how these assumptions influence the usability, accuracy and perceived precision of some readily available flight emission estimators.disCarbonOu...
