A new paper, Implementing effective carbon pricing, from the New Climate Economy shows that carbon pricing works and doesn’t harm the economy. It urges developed and emerging economies, with the G20 in the lead, to commit to introducing carbon prices of roughly comparable levels by 2020.

A new paper from the New Climate Economy shows there is large untapped potential for fuel efficiency gains in both aviation and shipping sectors that would cut costs and reduce emissions. International aviation and shipping have grown dramatically in the last few decades along with their emissions: aviation and shipping now produce 5% of global CO2 emissions, and by 2050, that share could rise to as much as 32%. Much of the potential to reduce emissions in aviation and shipping can be unlocked through existing technologies and practices that leading companies in each sector have already embraced. However, as this new paper shows, market failures and political barriers are hindering progress.
