How Were India's Carbon Market Targets Set?

Testing the claim that India's CCTS targets were benchmarked to each sub-sector's best performer, using three separate measures: whether the frontier plant was spared, how much pressure fell on the typical plant, and whether each target was calculated or drawn from a short list of flat rates.
