The detrimental effects of climate change are growing, yet investments in clean technologies are still grossly insufficient, making it necessary to re-think how these projects should be evaluated, structured and financed in order to render them viable and attractive opportunities to polluting alternatives.

The international community is essential in resolving this financing challenge, and host governments need to create an environment that levels the playing field for green investments vis-à-vis their conventional alternatives.
