WASHINGTON (Reuters) - The head of the International Monetary Fund called for "decisive steps" by European policymakers to deal with the region's financial crisis and said carbon taxes could deliver more revenues for countries worldwide with budget constraints.
In a speech on Tuesday focused on the upcoming Rio+20 earth summit in Brazil on June 20-22, IMF Managing Director Christine Lagarde said economic and financial stability was critical to addressing global environmental challenges.
The summit, 20 years after the original Rio Earth Summit that led to the Kyoto Protocol on capping greenhouse gas emissions, comes amid a faltering global economy and deep concerns over Europe's financial future.
