The voluntary carbon market is difficult to measure. The cost of carbon credits varies, particularly for carbon offsets, since the value is linked closely to the perceived quality of the issuing company. Third-party validators add a level of control to the process, guaranteeing that each carbon offset actually results from real-world emissions reductions, but even so there’s often disparities between different types of carbon offsets.
While the voluntary carbon market was estimated to be worth about $400 million last year, forecasts place the value of the sector between $10-25 billion by 2030, depending on how aggressively countries around the world pursue their climate change targets.
