Republican presidential candidate John McCain traveled to Europe and the Middle East last week, meeting with various European leaders to discuss climate change and U.S. foreign policy. McCain broached climate change in separate meetings with French President Nicolas Sarkozy, current U.K. Prime Minister Gordon Brown, and former U.K. Prime Minister Tony Blair, who recently announced his quest to secure a meaningful worldwide climate change agreement in the next two years. McCain also penned an editorial for the Financial Times about international cooperation. “We need a successor to Kyoto, a cap-and-trade system that delivers the necessary environmental impact in an economically responsible manner,” he wrote. “We need to unleash the power and innovation of the marketplace in order to meet our environmental challenges. Right now safe, climate-friendly nuclear energy is a critical way both to improve the quality of our air and to reduce our dependence on foreign energy sources.”
