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). Developed countries have committed, under the UNFCCC, to support containment and adaptation efforts in developing countries. Under the Copenhagen and Cancun agreements, developed countries have pledged to mobilize $100 billion in public and private financing per year for developing countries by 2020. In addition, the agreement establishes a new mechanism to ”facilitate the implementation and promotion of respect.” This ”non-contradictory” expert panel will try to help countries that are lagging behind their commitments get back on track. There is no penalty for non-compliance. President Obama was able to formally enshrine the United States in the agreement through executive measures because he did not impose new legal obligations on the country. The United States already has a number of instruments on the books, under laws already passed by Congress to reduce carbon pollution. The country officially joined the agreement in September 2016, after submitting its request for participation. The Paris Agreement was only able to enter into force after the formal accession of at least 55 nations representing at least 55% of global emissions. This happened on October 5, 2016 and the agreement came into force 30 days later, on November 4, 2016. Although the United States and Turkey are not parties to the agreement, as they have not indicated their intention to withdraw from the 1992 UNFCCC, they will continue to be required, as an ”Annex 1” country under the UNFCCC, to end national communications and establish an annual inventory of greenhouse gases.  The Paris Agreement provides for a number of binding procedural obligations.
The parties are committed to preparing, communicating and maintaining successive NDCs; ”domestic mitigation measures” to achieve their NDCs; report regularly on their emissions and on progress in implementing their NDCs.
