Cambridge Centre for Carbon Credits (4C)


4C is committed to releasing all of our research outputs under open source licenses, so that they can be freely reused and modified. If you do have improvements you would like to contribute back, please feel free to open up an issue on the relevant code repository.  Where source code has not yet been released, this is because it is currently under peer review and will be made available on request.  Where data has not yet been released, this is often because we have reverse engineered some necessary dataset and are determining the appropriate license for it for open release with the upstream stakeholders.
