Many companies say it is imperative for countries to agree to the five-yearly reviews so that investors get clear, long term policy signals.
From cloned cows in China to coal's woes across the world, Financial Times writers explore all the issues in the debate around global warming and climate change.

The debate is just one of the many bones of contention likely to arise during the two-week conference. Developing countries say the Paris accord should acknowledge developed nations' responsibility for carbon pollution since the industrial revolution.

"We need to discuss chapter by chapter," the French minister said.
Mr Fabius has told delegates from 195 countries converging on Paris this weekend to hand over their drafts of the accord by noon on Saturday December 5, leaving another week to try to overcome sticking points.
