China and the US have signed a non-binding, five-part plan to reduce greenhouse emissions by making heavy-duty vehicles more efficient and limiting output from coal-fired power plants, Financial Times reported. The agreement between the world’s largest polluters took place during broader talks on economic and strategic issues and should be implemented in October. Other points of the plan included promoting more energy efficient buildings, collecting better climate change data and encouraging smart grids. Although the agreement is non-binding, a White House environmental policy official said it could have a noticeable effect. Experts say that the new agreement bodes well for a 2015 climate change summit in Paris.
