China told delegates at the International Cooperative Conference on Green Economy and Climate Change that it will "step up" investment to fight climate change, Bloomberg reported. China’s science and technology minister, Wan Gang, said at the Beijing conference that the government will make investments to provide technical support for combating climate change, use price reforms to conserve resources, and also cut carbon emissions per unit of GDP by 40-45% of 2005 levels by 2020. Zhang Guobao, head of the National Energy Administration, also said the country would "openly welcome" investments from foreign renewable energy companies. The announcements come after Premier Wen Jiaobao said last week that China used 3.2% more energy per unit of GDP in the first quarter – increasing pressure to cut consumption for the remainder of the year.
