The long-term objective of the Paris Agreement is to keep the increase in global average temperature well below 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels; and to continue efforts to limit the increase to 1.5 degrees Celsius, while acknowledging that this would significantly reduce the risks and effects of climate change. This should require a rapid reduction in emissions to achieve “a balance between anthropogenic emissions from sources and the reduction of greenhouse gases from wells” in the second half of the 21st century. It also means increasing the parties` ability to adapt to the negative effects of climate change and “reconciling financial flows with a way to reduce greenhouse gas emissions and climate-resistant development.” All remaining parties to the agreement must present their new 2030 targets before the next major UN climate meeting, to be held in Glasgow, UK, in November 2021 (this year`s climate summit has been postponed due to the pandemic). To date, only 14 revised objectives have been proposed or presented. The 32-part document sets out a framework for global action on climate change, including climate change mitigation and adaptation, support for developing countries and transparency of reporting, and strengthening climate change goals. Here`s what to do: While stepping up NDCs` ambitions is an important goal of global inventory, it assesses efforts on weakening. The five-year revisions will also assess adaptation, climate change provisions, and technology development and transfer.  According to the United Nations Environment Programme (UNEP), temperatures are expected to rise by 3.2oC by the end of the 21st century, based solely on the current climate commitments of the Paris Agreement. To limit the increase in global temperature to 1.5 degrees Celsius, annual emissions must be below 25 Gigaton (Gt) by 2030. With the current commitments of November 2019, emissions by 2030 will be 56 Gt CO2e, twice the environmental target. To limit the increase in global temperature to 1.5 degrees Celsius, an annual reduction in emissions of 7.6% is needed between 2020 and 2030. The four main emitters (China, the United States, the EU-27 and India) have contributed more than 55% of total emissions over the past decade, excluding emissions due to land use changes such as deforestation. China`s emissions increased by 1.6% in 2018 to a peak of 13.7 Gt CO2 equivalent.
U.S. emissions account for 13% of global emissions and emissions have increased by 2.5% in 2018. EU emissions, which account for 8.5% of global emissions, have fallen by 1% per year over the past decade. Emissions fell by 1.3% in 2018. In 2018, 7% of India`s global emissions increased by 5.5%, but its per capita emissions are one of the lowest in the G20.  7 David Roberts, The Conceptual Breakthrough Behind the Paris Climate Treaty, VOX (December 15, 2015), on www.vox.com/2015/12/15/10172238/paris-climate-treaty-conceptual-breakthrough. The EU has been at the forefront of international efforts to combat climate change. It played an important role in mediating the Paris Agreement and continues to play a leading role at the global level. Whoever wins the U.S. presidential election, the United States officially withdraws from the Paris climate agreement on November 4. This measure is a blow to international efforts to stop global warming.
