Nicholas Stern, lead author of the influential Stern Review, comments on the effects of the ongoing economic crisis on climate change. In particular, he touches on green investment as an engine for stimulating growth. Others argue that additional regulation stymies growth and that an ailing world economy will lead to lower greenhouse gas emissions. Foresta takes issue with this position and believes that well-crafted regulation can jumpstart growth while making inroads against anthropogenic GHG emissions. Foresta endorses mechanisms that facilitate green investment, such as cap-and-trade's role in channeling carbon finance into renewable energies, clean technology and sustainable forestry.
