We started in the 1990s at sustainability startups, in government, a climate technology fund, and a global certification company. ClimateCHECK was launched in 2007 to advance the state of the art for MRV (measurement, reporting, verification) and we have since delivered services and solutions to over 400 organizations in over 50 countries. 

We have launched innovative solutions for climate change, cleantech and sustainability every 18-24 months throughout the 2000s, 2010s and are continuing into the 2020s, for example:
