Negotiators Tackle Rules for Implementing Paris Climate Pact

Moroccan Foreign Minister and COP22 President Salaheddine Mezouar (L) and French Minister for Environment Segolene Royal launch the opening of the UN Climate Change Conference 2016 (COP22) in Marrakech, Morocco, Nov. 7, 2016.

Negotiators from nearly 200 countries are meeting on how to implement the Paris Agreement on global warming.

Top U.N. climate top official Patricia Espinosa told delegates to the two-week meeting in Morocco, ”no politician or citizen, no business manager or investor'' can doubt the world is determined to shift toward a `”low-emission, resilient society.”

The immediate task is writing a detailed "rule book," including how to measure and report emissions.

They are also expected to explore how the world could make the shift to using virtually no fossil fuels responsible for greenhouse gas emissions.

So far, 100 countries have formally endorsed the agreement adopted last year in Paris, including top polluters China, the European Union, India and the United States. The deal aims to hold global temperature rise to an ambitious target of well below two degrees Celsius.

On a per-capita basis, rich countries like the United States, Australia and oil-rich Gulf nations, have the highest emissions.

The United Nations has said global emissions rise every year, reaching 52.7 billion tons in 2014, primarily driven by the rapid expansion of China, India and other Asian economies.

Meanwhile, average temperatures keep hitting new records globally. Last year was the hottest since reliable record-keeping began in the 19th century and this year is expected to be even hotter.
