BONN, Germany – As UN diplomats convened in Bonn Monday, developing nations were balking at the latest draft of a global climate agreement to be inked in Paris in December, negotiators and experts said.

The five-day session is the last formal parlay before heads of states and ministers gather in the French capital to seal a deal to beat back the threat of global warming and help poor nations cope with its impacts.

Monday will be the first opportunity for rank-and-file negotiators to weigh in on a new draft whittled down from 80 pages to 20 by two senior diplomats — one from Algeria, the other from the United States — leading the process.

Reactions from developing nations and veteran analysts of the talks, now in their third decade, suggest that sparks will fly at the opening session of UN climate talks.

Many countries are likely to insist that deleted passages be restored before the arduous job of line-by-line revisions can even begin.

“The text… cannot be used as a basis for negotiation, as it is unbalanced,” the African Group said in a statement released hours before the opening session.

The new draft “does not reflect the African Group positions, and crosses the group’s red lines,” it said.

The draft agreement “completely ignored the submissions of (the) G77 on finance”, said Gurdial Singh Nijar, a Malaysian negotiator and spokesman for the Like-Minded Developing Countries, a grouping which includes China and India, as well as many African, Asian and Latin American nations.

There is nothing, for example, “on the obligations of developed countries to provide the means of implementation” for relevant technology, he told AFP.

Another key element that many countries say was sidelined is a timetable for reviewing and ramping up national commitments — submitted ahead of the November 30-December 11 conference — to slash carbon emissions.

The pledges are a key pillar of the agreement, which would take effect in 2020.

In a related complaint, nations across the development spectrum expressed disappointment that the goal of “decarbonising” the global economy — essentially switching away from fossil fuels — was dropped from the draft.

Running through most of these issues is a deep divide between developing and developed countries on how to share out the task of curbing carbon emissions.
