About 190 nations agreed on Sunday the building blocks of a new-style global deal due in 2015 to combat climate change amid warnings that far tougher action will be needed to limit rising world temperatures.
Under the Lima deal, governments will submit national plans for reining in greenhouse gas emissions by an informal deadline of March 31, 2015 to form the basis of a global agreement due at a summit in Paris in a year's time.
The texts, breaking deadlock among weary delegates almost two days into overtime after two weeks of talks, appeased developing countries led by China and India, concerned that previous drafts imposed too heavy a burden on emerging economies compared to the rich.
"We've got what we wanted," said Indian Environment Minister Prakash Javedekar, who said the text preserved the notion enshrined in a 1992 climate convention that the rich have to lead the way in making cuts in greenhouse gas emissions.
It also satisfied rich nations led by the United States who say it is time for fast-growing emerging economies to rein in fast-rising emissions. China is now the biggest greenhouse gas emitter ahead of the United States, the EU and India.
"This is a good document to pave the way to Paris," EU Climate Action and Energy Commissioner Miguel Arias Cañete told Reuters at the end of two weeks of talks about limiting more floods, desertification, heat waves and rising sea levels.
