Feb 21 (Reuters) - The U.N. Environment Programme (UNEP) said on Monday that investments of 2 percent of world gross domestic product, or about ${esc.dollar}1.3 trillion a year, could bring a shift to a green economy and promote long-term growth.
It gave the following breakdown of the effects of allocating an additional 2 percent of GDP towards greening the economy, relative to 2 percent included in a "business as usual" (BAU) scenario.
The world economy would be 0.4 percent smaller in 2020 than BAU with big green investments, for instance, but rebound to be 15.7 percent bigger by 2050.
Here are the projected figures in the report. "Green" column shows the percentage difference of a green investment scenario relative to BAU, except renewable energy demand which is expressed in all columns as a percentage:
