The United Nations Environment Programme (UNEP) recently published the Emissions Gap Report 2024, in anticipation of the COP29 meeting of the UNFCCC to be held in Baku, Azerbaijan.

Key Highlights:

• Current Trajectory of Global Warming:
  • If countries continue with current environmental policies, global temperatures are expected to rise by 3.1°C above pre-industrial levels.
  • This is significantly higher than the Paris Agreement target of limiting global warming to well below 2°C, with an effort to cap it at 1.5°C.
• Paris Agreement at Risk:
  • Even if all Nationally Determined Contributions (NDCs) are fully implemented (including both unconditional and conditional emissions reduction targets), the world would still experience 2.6°C of warming by 2030.
  • This presents a major challenge to achieving the Paris Agreement’s climate goals.
• Urgent Need for Action:
  • To limit global warming to 1.5°C, greenhouse gas emissions must peak before 2025 and decline by 43% by 2030.
  • The report highlights the emission gap between current pledges and what is required to meet the 1.5°C goal.
• Record High Emissions:
  • Global greenhouse gas emissions hit a record 57.1 gigatons of CO? equivalent in 2023.
  • This represents an increase of 1.3% compared to 2022, continuing the upward trend from the previous decade.
• India’s Emissions:
  • India’s greenhouse gas emissions grew by 6.1% between 2022 and 2023.
  • Per capita emissions in India were 2.9 tCO?e in 2022, significantly lower than China (11 tCO?e) and the U.S. (18 tCO?e).
• G20 Countries’ Contribution:
  • G20 countries, excluding the African Union, contributed 77% of global emissions in 2023.
  • The six largest emitters (including China, U.S., and India) were responsible for 63% of global emissions.
  • This shows a significant imbalance in emissions, with developed countries having much higher per capita emissions compared to developing nations like India and Africa.
• Necessary Emissions Cuts:
  • To keep the 1.5°C target within reach, global emissions need to be cut by at least 7.5% annually until 2035.
  • Cost of bridging the emissions gap: Achieving net-zero by 2050 will require USD 900 billion to USD 2.1 trillion annually, approximately 1% of global GDP.
• Emission Reduction Pathways:
  • Renewable Energy: Scaling up solar and wind energy technologies could contribute up to 27% of the required emissions reductions by 2030.
  • Forest Conservation: Protecting and restoring forests could provide 20% of the required emissions reductions by 2030.
  • Other crucial measures include improving energy efficiency, transitioning to electric vehicles, and focusing on fuel switching in key sectors like transport, industry, and buildings.
• Disparities in Emissions:
  • Despite changes over the past two decades, large disparities remain between emissions across regions.
  • Developed countries have three times higher per capita emissions compared to the global average, while India, the African Union, and least developed countries continue to have much lower emissions.
• Call to Action:
  • UNEP Executive Director Inger Andersen urged countries to act now, stating: “No more hot air, please.” The urgency is to ramp up climate pledges and ensure stronger actions in the upcoming COP29 talks in Baku, Azerbaijan (November 2024), where nations must work to get on a 1.5°C pathway.

United Nations Environment Programme (UNEP)

• Established: 1972, following the United Nations Conference on the Human Environment in Stockholm.
• Headquarters: Nairobi, Kenya.
• Governing Body: The United Nations Environment Assembly (UNEA), which is the world’s highest-level decision-making body on environmental matters, with 193 Member States.
• Programs & Initiatives: UNEP leads global efforts on climate action, ecosystem restoration, clean seas, and supports the Sustainable Development Goals (SDGs).
• Reports: UNEP publishes crucial assessments like the Emissions Gap Report, Global Environment Outlook, and Adaptation Gap Report, influencing global environmental policies.
