Hey, guess who paid a visit over the weekend? Wen Jiabao, who came to Shanghai as part of an inspection tour of east China. The Premier took the opportunity to call for a more balanced and energy-efficient economic development model, especially important considering China’s plans to cut CO2 emissions per unit of GDP by 40 to 45% by 2020. How? Through the magic of better technology. While we’ve never been quite convinced that tech would be the easy button on our environmental problems, we’re always happy for a chance to see Grandpa Wen!
