LONDON (Reuters) - The G20 group of leading economies must come forward with more ambitious 2030 climate action plans, Britain's Alok Sharma, president of the upcoming United Nations COP26 climate change conference, will say on Tuesday.

With less than a month before the talks begin in Glasgow, Scotland, Sharma will seek to increase pressure on those who have yet to enhance national goals to cut greenhouse gas emissions under plans known as "Nationally Determined Contributions" that are central to the 2015 Paris Agreement.
