Longest UN climate talks end with no deal on carbon markets

Marathon international climate talks ended Sunday with negotiators postponing until next year a key decision on how to regulate global carbon markets.

After two weeks of negotiations in Madrid on tackling global warming, delegates from almost 200 nations passed declarations calling for greater ambition in cutting planet-heating greenhouse gases and in helping poor countries that are suffering the effects of climate change.

But despite holding the longest climate talks ever in 25 nearly annual editions they left one of the thorniest issues for the next summit in Glasgow, in a year’s time.

Carbon markets put a price on emission of carbon dioxide, the main greenhouse gas, and allows countries or companies to trade emissions permits that can be steadily reduced — encouraging the uptake of low-emission technologies.
