UN Climate Summit hosts fuel hopes for Paris deal

The United Nations’ decision to ask countries to pledge greenhouse gas targets ahead of a global deal on climate change, has proved a “game changer” according to the Peruvian and French governments.

Hosts of the crucial UN climate change summits in 2014 and 2015 respectively.

Over the course of this year, countries have been submitting their Intended Nationally Determined Contributions (INDCs) to the United Nations, outlining the post-2020 emissions reduction targets they intend to enact under a Paris climate change deal.

Some critics argue this voluntary approach lacks the authority of a legally binding agreement, while scientists have warned the emissions reductions pledges made to date are short of what is required to ensure a reasonable chance of limiting temperature increases to the internationally agreed 2°C.
