New paper finds CO2 emissions self-regulate as economic prosperity increases, without carbon taxes
A paper published today in Global Environmental Change finds that CO2 emissions are essentially self-regulating, that after countries reach a higher GDP level, CO2 emissions stabilize or even decrease, without the imposition of carbon taxes. According to the authors, "Evidence from recent four decades indicates that per capita carbon dioxide emission first significantly and monotonously increase at low income level and flattens after per capita income reaches at about 22,000 $ (2005 constant price)." "A 'first-rise-then-flat' relationship of carbon dioxide per capita and GDP per capita was found", which suggests carbon taxes are unnecessary to stabilize emissions in higher GDP countries.
