The Conference of the Parties (COP) convenes member countries annually to determine climate measures, responsibilities, and ambitions. COP 28, held in Dubai in 2023, focused on developing a roadmap towards achieving net-zero emissions, a critical step in combating climate change. It was a significant event in the global effort to address climate change and transition towards a sustainable future.

Overview: A global summit on climate change and sustainability 

• Sets the stage for discussions on key environmental challenges and steps to achieve a net-zero future.
• Aims to promote collaboration among countries, industries, and civil society.
• Signals renewed urgency to tackle climate change.
• Emphasizes collective responsibility and innovative solutions for a sustainable world.

Key takeaways from COP28 discussions:

1. Transitioning Away from Fossil Fuels: The conference emphasized the need to transition away from fossil fuels in a just, orderly, and equitable manner to achieve net-zero emissions by 2050. This marked a significant milestone, as the UN Climate Agreement was the first official agreement for a transition away from fossil fuels, defining them as stranded assets. The agreement also emphasized the phasing out of inefficient fossil fuel subsidies and highlighted the need to accelerate action in this critical decade to address climate change effectively.
2. Global Stocktake: Nearly 200 countries pledged to move away from fossil fuels, a breakthrough that came in the waning hours of the UN Climate Change Conference (COP28). The decision taken during the Global Stocktake highlighted the significance of countries submitting new and improved Nationally Determined Contributions (NDCs) well before the COP30 conference scheduled to take place in Brazil in 2025. These revised NDCs include updated targets for 2030 along with new targets for 2035 and should be more ambitious, reflecting the transformation across several sectors to drive down emissions and enhance adaptation efforts. The outcomes from the global stocktake at COP28 have laid the foundation for increased climate ambition and collaboration toward achieving global climate goals.
3. Investments in Renewable Energy: The final text of COP28 stipulated the tripling of new investments in renewable energy and the “transitioning away” from fossil fuels in power systems. The UAE Consensus, a key outcome of COP28, aims to triple renewable energy and double energy efficiency by 2030. The International Energy Agency (IEA) has stated that $4.5 trillion will be needed each year for clean energy alone by the early 2030s, up from $1.8 trillion now. However, the energy sector still faces critical issues, such as the need for innovative funding, encompassing both governmental and private sector investments in research and development.
4. Methane Pledges: Several countries have joined the Global Methane Pledge, aiming to reduce methane emissions by 30% by 2030. GMP partners have announced over $1 billion in grant funding for methane action mobilized since COP27, which will lead to the mobilization of billions of dollars in investment to reduce methane emissions. This funding represents more than triple the current level
5. Buildings Breakthrough: 27 countries pledged to participate in the Buildings Breakthrough, aiming to improve building energy efficiency. The governments of France and Morocco, in collaboration with the UN Environment Programme (UNEP), have launched the “Buildings Breakthrough” initiative during COP28. This effort aims to unite countries to accelerate the transformation of the building sector, which is responsible for 21% of global greenhouse gas emissions. The goal is to make near-zero emissions and climate-resilient buildings the new standard by 2030.
6. Global Cooling Pledge: More than 60 countries joined the Global Cooling Pledge, aiming to reduce air conditioning and refrigeration use. The goal of this initiative is to promote higher levels of international collaboration by establishing global targets to decrease emissions related to cooling by 68% by 2050 from the current levels, to significantly improve accessibility to sustainable cooling by 2030, and to increase the average efficiency of new air conditioning units globally by 50%.
7. Funding for Loss and Damage: The conference operationalized the Loss and Damage Fund, established during COP27, to provide support for countries experiencing climate-related losses and damages. The fund, established at a conference, received over $700 million in pledges from countries like the UAE, Germany, the US, and the EU. However, concerns arose about long-term financing and the World Bank’s use as an interim host.
8. New Finance Pledges: Several countries and organizations made new finance pledges to support climate action. During its second replenishment, the Green Climate Fund (GCF) received a significant funding boost. Countries such as Australia, Estonia, Italy, Portugal, Switzerland, and the United States pledged a total of USD 3.5 billion, which will enable the GCF to provide essential resources to developing nations. These resources will help address climate change impacts and support vulnerable communities.
9. Emissions Gap Report: The 2023 edition of the Emissions Gap Report released during COP 28 by the UN Environment Programme emphasized the urgent need to reduce predicted 2030 emissions by 28–42% compared to current policy scenarios if we are to achieve the Paris Agreement goals of limiting global warming to 2°C and 1.5°C, respectively. To limit the global temperature increase to 2.9°C, the report suggests implementing unconditional Nationally Determined Contributions (NDCs), while achieving additional conditional NDCs could lead to a warming of 2.5°C above pre-industrial levels.
10. Climate equity: COP 28 explores the potential use of artificial intelligence (AI) and Earth observations (EO) for climate adaptation, specifically in the development of insurance and financial mechanisms. The conference highlighted the importance of private sector involvement, as it plays a key role in implementing risk transfer mechanisms based on AI and EO. This collaboration offers new solutions and opportunities in the field of climate adaptation. These key takeaways from COP 28 underscore the collective commitment of nations, industries, and civil society to address climate change and transition towards a sustainable future.

Challenges ahead at COP 28

• One of the biggest challenges is making sure national net-zero plans are credible; to date, ~75% of targets set by countries fall somewhat short. This poses a critical challenge as nations strive to align their commitments with the ambitious goals outlined in the global climate agenda.
• The interplay between government bodies and private companies will be crucial for implementing effective policies and initiatives to reduce emissions and achieve net-zero goals. This collaborative approach would need high-level political and collective action to accelerate efficiency improvements and scale renewables. 
• Globally the transport sector accounts for over one-fifth of CO2 emissions. The adoption of sustainable transportation practices, such as the use of electric vehicles and shared mobility services to reduce CO2 emissions remains essential. However, this may face resistance from the public due to concerns about cost, convenience, and perceived loss of personal freedom.
• The Global Renewables and Energy Efficiency Pledge aims to achieve 11,000 GW of renewable capacity by 2030 and double the energy efficiency improvement rate from 2% to 4%. However, it’s worth noting that China and India did not sign up to the pledge. India, despite being a global renewables leader, abstained from signing the pledge due to concerns related to the focus on phasing out unabated coal. This poses a concern in transitioning away from fossil fuels towards cleaner energy sources. 

Conclusion

COP 28 served as a platform for robust discussions on transitioning towards a net-zero future. While challenges exist in phasing out fossil fuels and embracing cleaner energy sources, the conference highlighted the shared dedication needed to address climate change effectively. By fostering coalitions and innovation, stakeholders can work towards realizing a sustainable and resilient world for future generations. This blog encapsulates the essence of COP 28’s roadmap towards achieving net zero carbon emissions and underscores the urgency of taking decisive action to combat climate change.
