The Emissions Gap Report 2023, subtitled “Broken Record – Temperatures hit new highs, yet world fails to cut emissions (again)”, was recently released by the United Nations Environment Programme (UNEP). The report highlights the crucial need for urgent climate action to counter the alarming trajectory of global temperature rise. This is the 14th edition in a series that enlists some of the world’s top climate scientists to examine future trends in greenhouse gas emissions and propose potential solutions to combat global warming.
About the Emissions Gap Report
The Emissions Gap Report is an annual initiative by UNEP that provides insights into the state of global emissions prior to the Annual Climate negotiations. The report readily tracks the difference between the current direction of global emissions guided by national commitments, and the desired trajectory to limit global warming to a 1.5°C increase.
Key Highlights of the Report
The report shows concerning trends. The existing pledges under the Paris Agreement are directing the world toward a 2.5-2.9°C temperature rise above pre-industrial levels by the end of this century. Substantial emission cuts of 28-42% would be necessary by 2030 to limit warming to 1.5-2°C. Additionally, greenhouse gas emissions hit a fresh record of 57.4 Gigatonnes of Carbon Dioxide Equivalent in 2022, marking a 1.2% increase from the previous year. Fossil CO2 emissions, which account for approximately two-thirds of current GHG emissions, increased between 0.8–1.5% in 2022, contributing significantly to the overall increase in GHG emissions.
Emissions across Different Sectors and Regions
Emissions widely vary across sectors, with energy supply contributing most to emissions in 2022 (20.9 GtCO2e or 36% of the total), followed by industry, agriculture, transport and buildings. The report also notes varied trends among G20 countries, with increases observed in China, India, Indonesia, and the USA, and decreases in Brazil, the European Union, and the Russian Federation. Collectively, the G20 accounts for 76% of global emissions.
Challenges: Mitigation Efforts and Net-Zero Pledges
According to the report, if current policies and pledges persist, global warming could reach 3°C above pre-industrial levels by the end of the century. Unconditional Nationally Determined Contributions could limit this rise to 2.9°C, while conditional NDCs might cap it at 2.5°C. However, the report also points out that none of the G20 countries are reducing emissions at a pace consistent with their net-zero targets. Under the best-case scenario, the chance of limiting warming to 1.5°C remains only 14%.
Policy Progress and Challenges
There has been some progress since the Paris Agreement in narrowing the implementation gap, albeit not adequate. Nine countries have updated their NDCs, which could result in an annual reduction of about 9% in emissions by 2030. But additional reductions are essential to establish least-cost pathways for limiting global warming to 1.5°C.
Recommendations to Bridge the Emissions Gap
The Emissions Gap Report calls for several measures. Global low-carbon development transformations, particularly focusing on the energy transition, are required. Support and financing must be extended, especially from countries with greater capacity to generating emissions, to developing nations. Implementing new methods of carbon dioxide removal is stressed upon, though it is acknowledged that the technology is not yet fully developed.
The Efforts of India to Reduce Emissions
India has launched several initiatives to curb its emissions. These include the transition from Bharat Stage-IV to Bharat Stage-VI emission norms, launching the UJALA scheme and the International Solar Alliance, formulating the National Action Plan on Climate Change, and plans for Ethanol Blending by 2025. India has also updated its NDCs.
United Nations Environment Programme: A Brief Overview
Established on 5th June 1972, UNEP is a leading global environmental authority. It sets the global environmental agenda, advocates sustainable development within the United Nations system, and acts as an authoritative advocate for global environment protection. Its campaigns include Beat Pollution, UN75, World Environment Day, Wild for Life, among others.
