'Honeymoon Over', Rules for U.N. Climate Pact May Take Two Years

A first United Nations meeting on implementing a 2015 global agreement to combat climate change showed it could take two years to work out a detailed rule book for a sweeping shift from fossil fuels, delegates said.

The May 16-26 talks marked a return to technical work and the end of a "honeymoon period" since the Paris Agreement was worked out by almost 200 nations in December to cut greenhouse gas emissions and limit rising temperatures.

"My bet is 2018, everything will be done (in) a maximum two years," Laurence Tubiana, France's climate ambassador, told Reuters when asked how long it would take to negotiate a set of rules. Several other delegates gave similar estimates.

Tubiana said the Bonn talks had not exposed big, unexpected problems with the Paris text that could mean an even longer haul.  "There was no shouting, no crying," she said.

Details left vague by the 31-page Paris Agreement include how countries will report and monitor their domestic pledges to curb greenhouse gas emissions and adapt to changes such as more floods, storms, desertification and rising seas.

Under the Paris deal, most countries' goals for combating climate change are for the years from 2020-2030.
