reduce emissions per capita by 9% by 2030, while providing hope in the eyes of the conference organizers for further reductions in the future that would allow meeting a 2 °C target. Think-tanks such as the World Pensions Council (WPC) argued that the keys to success lay in convincing officials in the U.S. and China, by far the two largest national emitters: "As long as policy makers in Washington and Beijing didn't put all their political capital behind the adoption of ambitious carbon-emission capping targets, the laudable efforts of other G20 governments often remained in the realm of pious wishes. Things changed for the better on 12 November 2014 when President Obama and General Secretary Xi Jinping agreed to limit greenhouse gases emissions." President Obama insisted on America's essential role in that regard: "We've led by example ... from Alaska to the Gulf Coast to the Great Plains ... we've seen the longest streak of private job creation in our history. We've driven our economic output to all time-highs while driving our carbon pollution down to its lowest level in nearly two decades. And then, with our historic joint announcement with China last year, we showed it was possible to bridge the old divide between developed and developing nations that had stymied global progress for so long ... That was the foundation for success in Paris." Harvard University published a case study on one aspect of the negotiations, focussing on the protection of forests. Outcome On 12 December 2015, the participating 196 countries agreed, by consensus, to the final global pact, the Paris Agreement, to reduce emissions as part of the method for reducing greenhouse gas. In the 12-page document, the members agreed to reduce their carbon output "as soon as possible" and to do their best to keep global warming "to well below 2 degrees C". In the course of the debates, island states of the Pacific, the Seychelles, but also the Philippines, their very existence threatened by sea level rise, had strongly voted for setting a goal of 1.5 °C instead of only 2 °C. France's Foreign Minister, Laurent Fabius, said this "ambitious and balanced" plan was an "historic turning point" in the goal of reducing global warming. However, some others criticized the fact that significant sections are "promises" or aims and not firm commitments by the countries. Non-binding commitments, lack of enforcement mechanisms The Agreement will not
