Greenhouse-cuts bill 'could reach 41 trillion yuan'

China's post-2020 climate action plan will be "quite ambitious" and may involve estimated investment of more than 41 trillion yuan ($6.6 trillion) by 2030, according to a lead climate negotiator.

The action plan is to be announced by the end of this month.

The country's intended nationally determined contribution will differ from those of other countries because it will announce a series of objectives in addressing climate change up to 2030, Xie Zhenhua said.
