A study, prepared by some of the nation’s top climate change policy advisers, proposes that with the right policies emissions growth could slow by 2020 with levels peaking around 2030. “As soon as possible, study and draft relative and then absolute targets to cap the total volume of carbon dioxide emissions,” says the preface of the report, obtained by Reuters. “Establishing and acting on quantified targets and corresponding policies to address climate change in the medium to long-term is already a matter of great urgency.” The call for “quantified targets” to cap greenhouse gas pollution marks a high-level public departure from China’s reluctance to spell out a proposed peak and date for it. This also signals that Beijing wants to play an active role in seeking agreement for a new international climate change pact.
