Despite leading the world in clean energy investment in recent years, China continues to engage in massive expansion of coal power thanks to policies that effectively subsidise and (over)incentivise coal power investment. This column examines the effects of the 2014 devolution of authority from the central government to local governments on approvals for coal power projects. It finds that the approval rate for coal power projects is about three times higher when the approval authority is decentralised, and provinces with larger coal industries tend to approve more coal power.

Philippe Aghion of Harvard University talks to Romesh Vaitilingam about his research on how government interventions can encourage firms to shift from ‘dirty’ to ‘clean’ innovation, thereby sustaining growth while mitigating climate change. He describes the microeconometrics of climate change as virgin territory, where research can make a real difference to the green policy agenda. The interview was recorded at the annual congress of the European Economic Association in Glasgow in August 2010. [Also read the transcript]

How will proposed increases in energy R&D funding affect other types of R&D spending? This column provides evidence that should dampen concerns about crowding out – increased R&D in response to policies designed to enhance clean-energy innovation most likely comes at the expense of R&D in dirty-energy technologies.

No climate-change strategy will work unless it is consistent with developing countries' continued growth. So curbing emissions requires cheaper clean energy than is currently available. And that requires innovation.
