China is set to reveal how much it intends to cut its carbon emissions by beyond 2020, Chinese Premier Li Keqiang has said. Mr Li is on an official visit to France where a UN-led climate summit will be held later this year. After meeting officials in Brussels, he said the details would be announced by the end of the month, which is Tuesday. Last November, China – the world’s top greenhouse gas emitter – committed for the first time to limit its output. Chinese President Xi Jinping said the country would target 2030 for its emissions to peak.
