In fighting of global economic recession, a greening of fiscal stimulus packages should be considered. I think this is an important massage for the leaders of most powerful economic gathering in The London Summit 2009.
I notice recent policy brief of UNEP called Global Green New Deal (GGND). The proposal says that fiscal stimulus should prioritize energy efficient buildings and investments in sustainable transport and renewable energy. In the meantime, developing countries should prioritize investment in agricultural productivity measures, freshwater management, and sanitation, as these have demonstrable and exceptional social returns.
