No Green Growth Without Innovation

This Policy Brief attempts to change the terms of the debate surrounding climate change policy. The authors argue that policymakers should do more to encourage innovation and investment in green research and development rather than focusing solely on the setting of a carbon price. Using a model developed by Aghion in a previous paper, they argue that a carbon price would have to be about 15 times higher in the first five years and 12 times higher in the next five years if innovation is not properly subsidized by governments. The authors also provide several policy recommendations for incentivising this type of green growth in the private sector.
