Papua New Guinea formally submitted its "Nationally Determined Contribution" (NDC), committing to use 100 percent renewable energy by 2030. This first NDC submission marks a step forward in implementing the landmark Paris Climate Agreement.
The Paris Agreement adopted last year reflects the collective vision of 195 countries, but it's just the start of a longer process. While the Agreement lays out goals, the ability to achieve them depends on the rules, guidelines and processes to be hammered out in the months and years to come.
This chart outlines key tasks included in the Paris Agreement and accompanying draft decision that must be completed by UNFCCC groups and Parties before the Agreement enters into force.
Most of the discussion about the Paris Agreement focuses on countries' new climate plans, which are aimed at the post-2020 period. But the decisions made in Paris can also ramp up action in the short term, too.
One of the new Agreement's core ingredients is known as the ambition mechanism, or cycles of action. This mechanism lays out a process to continue strengthening countries' climate action every five years, starting before 2020.
Countries’ new climate plans should be seen as the floor rather than the ceiling. Low-carbon solutions will become increasingly affordable and accessible over time, allowing nations to gradually ratchet up their ambition.
Last week, International climate negotiators started their journey toward establishing a new international climate agreement.
After two weeks of difficult negotiations and a nail-biting finale, delegates in Lima laid the groundwork for a successful international climate agreement in Paris next year.
This paper reviews past practice in the UNFCCC and examines some of the most promising options to improve the effectiveness of the UNFCCC.
