UN talks agree to build a new-style climate deal in 2015

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. 

Some environmental groups, however, said the deal, reached at a tent city on a military base in Lima, was far too weak. 

"We went from weak to weaker to weakest," Samantha Smith of the WWF conservation group said of successive drafts at the Lima talks. "This leaves a huge amount for governments and everyone else to do in the next 12 months." 

NEW STYLE 

The idea of a UN deal with obligations for all nations marks a shift from the 1997 Kyoto Protocol, which obliges only the rich to cut emissions. 

"What we are seeing is a new form of international cooperation on climate change where all countries participate with a new set of rules," said Jennifer Morgan of the World Resources Institute think-tank. 

But it leaves a lot of work for 2015.  "I am not going to say it will be a walk in the park in Paris," said Ed Davey, British Secretary of State for Energy and Climate Change. 

The U.N. Climate Change Secretariat say that the combined pledges by all nations likely in Paris will be too weak to achieve a goal of limiting warming to an agreed goal of 2 degrees Celsius (3.6 Fahreneit) above pre-industrial times. 

Under the Lima deal, national pledges will be added up in a report by Nov. 1, 2015, to assess their aggregate effect in slowing rising temperatures. 

But, after opposition led by China, there will not be a full-blown review to compare each nation's level of ambition. In a deal with the United States last month, China agreed to cap its emissions by around 2030. 

And the text lays out a vast range of options for the Paris accord, including the possibility of aiming for zero net global emissions by 2100 or earlier in a drastic shift from fossil fuels towards renewable energies such as wind and solar power.
