Investing in the Clean Trillion: Closing the Clean Energy Investment Gap

Abstract

In 2010 world governments agreed to limit the increase in global temperature to two degrees Celsius (2 °C) above pre-industrial levels to avoid the worst impacts of climate change. To have an 80 percent chance of maintaining this 2 °C limit, the IEA estimates an additional $36 trillion in clean energy investment is needed through 2050 -- or an average of$1 trillion more per year compared to a "business as usual" scenario over the next 36 years.This report provides 10 recommendations for investors, companies and policymakers to increase annual global investment in clean energy to at least $1 trillion by 2030 -- roughly a four-fold jump from current investment levels
