The financial benefits of limiting global warming to 1.5ºC outweigh the high cost of doing so, even at a median cost global price of more than $100 per tonne of carbon dioxide, according to a study by UK researchers and academics. Their cost-benefit analysis, The Economics of 1.5°C Climate Change, argues that ambitious carbon pricing programmes can reduce mitigation costs in the medium-to-long term by comparison with scaling up fragmented regulatory measures. This could be particularly effective for developing economies, where mitigation costs could be relatively low.
