Professor Valérie Masson-Delmotte:

There are risks associated with ramping up ambition for mitigation now. It is a risk associated with, for example, negative effects of ambitious mitigation for specific sectors and people. There is the risk of stranded assets in the economic world. As the report shows, we are at a crossroads in dealing with these risks and it is important that we examine them and identify the risks, in respect of which we understand the consequences, and those that are uncertain. For me, large-scale use of bioenergy, with capture and storage, is uncertain.
