Which Countries Are Not Signed Up To The Paris Agreement
Under the Paris Agreement, each country must define, plan and report regularly on its contribution to the fight against global warming.  There is no mechanism for a country to set an emission target for a specified date, but any target should go beyond the previous targets. The United States formally withdrew from the agreement the day after the 2020 presidential election, although President-elect Joe Biden said America would return to the agreement after his inauguration.  These rules of transparency and accountability are similar to those in other international agreements. Although the system does not include financial sanctions, the requirements are intended to easily monitor the progress of individual nations and promote a sense of overall group pressure, discouraging any towing of feet among countries that might consider it. Paragraphs 6.4 to 6.7 introduce a mechanism “that contributes to the reduction of greenhouse gases and supports sustainable development.”  Although there is not yet a concrete name for the mechanism, many parties and observers have informally partnered around the name of the “sustainable development mechanism” or “SDM”.   The MDS is seen as the successor to the Clean Development Mechanism, a flexible mechanism under the Kyoto Protocol that would allow the parties to jointly monitor emissions reductions for their planned national contributions. The Sustainable Development Mechanism sets the framework for the future of the post-Kyoto sustainable development mechanism (2020). [must update] Specific results of increased attention to adjustment financing in Paris include the announcement by the G7 countries of $420 million for climate risk insurance and the launch of a Climate Risk and Early Warning Systems (CREWS) initiative.  In 2016, the Obama administration awarded a $500 million grant to the “Green Climate Fund” as “the first part of a $3 billion commitment made at the Paris climate talks.”    To date, the Green Climate Fund has received more than $10 billion in commitments.
The commitments come mainly from developed countries such as France, the United States and Japan, but also from developing countries such as Mexico, Indonesia and Vietnam.  How each country is on track to meet its obligations under the Paris Agreement can be constantly monitored online (via the Climate Action Tracker and the climate clock).
