Environmental legislation dubbed a Green New Deal championed by Rep. Alexandria Ocasio-Cortez has drawn widespread attention — despite the fact that no one really knows for sure what it is.

Now, as Ocasio-Cortez prepares to release a blueprint, details are emerging.

"Next week, we plan to release a resolution that outlines the scope and scale of the Green New Deal," according to a letter the New York Democrat sent to colleagues. "In it, we call for a national, social, industrial and economic mobilization at a scale not seen since World War II."
