FACTBOX-Global green economy stimulus plans

(Updates throughout)

March 26 (Reuters) - The United States, Europe, China and
South Korea lead global "green" spending plans after committing
$300 billion-500 billion to boost low-carbon technologies and
protect the environment, under wider plans to boost the global
economy.

Green spend accounts for about 15 percent of total economic
stimulus cash of $2 trillion-3 trillion [ID:nL6918662].

Views vary on how much money is needed to fight climate
change. Actual global investment in low-carbon technologies was
about $150 billion in 2008.

Estimates on the long-term investment required, and of
short-term, green stimulus spend committed so far, follow.
