The Emissions Gap Report in 60 seconds. The new edition of the Emissions Gap Report urges the world to take drastic and unprecedented measures to reduce emissions starting in 2020 and throughout the rest of the decade in order to slow global warming by 1.5 ° C.
- With current climate commitments, the world is heading for a temperature rise of 3.2 ° C by the end of the century, reveals a new UN report.
- The technologies and policies required to reduce emissions already exist, and must be implemented immediately.
- Only 5 members of the G20 have committed to a timeline to achieve emissions neutrality.
Geneva, November 26, 2019.- Global greenhouse gas emissions must fall 7.6% each year between 2020 and 2030 for the world to slow global warming by 1.5 ° C this century, warns a new report from the United Nations Environment Program ( UNEP) launched today in Geneva.
The landmark Emissions Gap Report indicates that even if all the unconditional commitments of the Paris Agreement are implemented, temperatures will rise 3.2 ° C by the end of the century, leading to far-reaching and destructive climate impacts. and to achieve the 1.5 ° C target, emission reduction commitments must be fivefold.
The tenth edition of the UNEP report will feed the debate at the 25th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP25), which will take place from 2 December in Madrid, Spain. In 2020, at COP26 in Glasgow, United Kingdom, nations are expected to strengthen the ambition of their climate commitments.
“In the last ten years the Emissions Gap Report has sounded the alarms. And in those ten years the world has only increased its emissions, "said UN Secretary General António Guterres." There has never been a more important time to listen to science. If we do not heed these warnings and we do not take drastic measures to To reverse emissions, we will continue to witness deadly and catastrophic heat waves, storms and pollution, ”he added.
The Intergovernmental Panel on Climate Change (IPCC) warned that global warming above 1.5 ° C by the end of the century will increase the frequency and intensity of the impacts of climate change.
"Our collective failure to act decisively and in time against climate change means that we must now make more drastic reductions in emissions - more than 7% every year for the next decade," said Inger Andersen, UNEP Executive Director.
“This shows that countries simply cannot wait until the end of 2020, when new climate commitments come into force, to step up action. National governments and every city, region, company and individual must act now, ”Andersen added.
“During 2020 we need, first, effective measures to reduce emissions as much as possible. Next, we must strengthen Nationally Determined Contributions (NDCs) to drive the necessary transformations in our economies and societies, making up for lost time. If we don't do this, the 1.5 ° goal will be out of reach before 2030 ″, he warned.
G20 nations are responsible for 78% of all global emissions, but only five of these countries have committed to a long-term zero emissions goal, the report indicates.
In the short term, developed countries will have to reduce their emissions faster than developing countries, for equity reasons. However, all countries should contribute more for the collective good. Developing countries can learn from, and can even surpass, successful efforts in developed countries and adopt cleaner technologies at a faster rate.
The report indicates that by 2020 all nations should substantially increase ambition in their NDCs, and follow up on policies and strategies to implement them. Solutions are available to make it possible to meet the targets agreed in Paris, but they are not being implemented at the required speed or on a sufficient scale.
Each year, the Emissions Gap Report assesses the disparity between projected 2030 emissions based on current commitments and levels consistent with the 1.5 ° C and 2 ° C targets set in the Paris Agreement.
The report reveals that greenhouse gas emissions have increased 1.5% annually over the last decade. In 2018, they reached a record 55.3 gigatons of CO2 equivalent - including changes in land use, such as deforestation.
To limit the rise in temperature, 15 gigatons of CO will be required2 equivalent less for the 2 ° C goal, and 32 gigatons of CO2less equivalent for the 1.5 ° C target. This implies that emissions cuts of 7.6% per year are necessary between 2020 and 2030 to meet the 1.5 ° C target and 2.7% per year for the 2 ° C target.
It is still possible to limit climate change to 1.5 ° C, according to the report. The solutions are plentiful. There are many ambitious efforts by governments, cities, businesses and investors, and there is a greater understanding of the additional benefits of climate action, such as clean air and the push for the Sustainable Development Goals.
As it does every year, the report focuses on the potential of selected sectors to achieve emissions cuts. In this edition we analyze how the energy transition and the potential for efficiency in the use of materials can contribute to closing the emissions gap.
