A carbon pricing policy is needed so that, through taxation, emissions trading or regulation, people are faced with the full social costs of their actions. The aim should be to build a common global carbon price across countries and sectors.
Reducing emissions will make us better off. The long-term benefits of shifing the world onto a low-carbon path could be in the order of $2.5tr each year.
Barriers to energy efficiency must be removed. People must be educated about what they can do to respond to climate change.
Fostering a shared global understanding of the nature of climate change and its consequences is critical in shaping behaviour, as well as in underpinning both national and international action.
