Before the Paris climate talks, President Obama`s negotiators wanted to make sure it would take time for the United States to come to terms with a change of direction. 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.  “A safer, safer, more prosperous and freer world.” In December 2015, President Barack Obama envisioned leaving today`s children when he announced that the United States, along with nearly 200 other countries, had committed to the Paris Climate Agreement, an ambitious global action plan to combat climate change. Implementation of the agreement by all Member States will be evaluated every five years, with the first evaluation in 2023. The result will be used as an input for new national contributions from Member States.  The inventory will not be national contributions/achievements, but a collective analysis of what has been achieved and what remains to be done. “And then, in a way, you prepare for what happened.” Although this has been going on for a long time, there is still a sense of disappointment for many Americans who believe that climate change is the greatest global challenge and that the United States should oppose it. The 32-day document outlines how countries should reduce their emissions, adapt to the effects of climate change and finance the low-carbon economy in the coming decades. In 1992, President George H.W. Bush joined 107 other heads of state at the Rio Earth Summit in Brazil to adopt a series of environmental agreements, including the UNFCCC framework, which is still in force today.
The international treaty aims to prevent dangerous human intervention in the planet`s climate systems in the long term. The pact does not set limits on greenhouse gas emissions from individual countries and does not contain enforcement mechanisms, but establishes a framework for international negotiations on future agreements or protocols to set binding emissions targets. Participating countries meet annually at a Conference of the Parties (COP) to assess their progress and continue discussions on how best to combat climate change. 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). In an effort to “significantly reduce the risks and effects of climate change,” the agreement calls for the average increase in global temperature over this century to be well below 2 degrees Celsius, while continuing efforts to limit temperature rise to 1.5 degrees. It also calls on countries to commit as quickly as possible to comparing global greenhouse gas emissions and to become carbon neutral by the second half of this century. To achieve these goals, 186 countries – responsible for more than 90% of global emissions – presented CO2 reduction targets prior to the Paris conference, known as “determined national contributions” (INDC).
