The Next Steps For Meeting Nationally Determined Contributions After COP26

Reductions in emissions of carbon dioxide and other greenhouse gases (GHG) must be achieved in the coming decades to avoid catastrophic global temperature rises. Limiting global warming to within 1.5°C will require rapid, far-reaching, and unprecedented changes in all sectors. GHG emissions in Asia and the Pacific now account for over 50% of the world’s total.

These warnings and the urgent need for climate action and solutions were discussed at the 2021 ADBI Annual Conference on Climate Change Mitigation and Green Finance, held on 1–3 December, which featured a keynote speech from Jim Skea, Co-Chair of the Intergovernmental Panel on Climate Change’s Working Group III, and remarks from Asian Development Bank President Masatsugu Asakawa.

During the conference, COP26 President Alok Sharma highlighted in his keynote speech the role of the Glasgow Climate Pact (UNFCCC 2021) in bringing countries to the table to revisit and strengthen their 2030 emission reduction targets in alignment with the Paris temperature goals.

Junhong Chang, Executive Director at the World Bank Group, noted that climate finance commitments by major multilateral development banks rose to a total of $66 billion in 2020 from $61.6 billion in 2019, and 58% ($38 billion) was committed to low- and middle-income economies.

We highlight some of the key findings and recommendations from the ADBI Annual Conference.

Greening the energy sector

The energy sector in developing Asia heavily depends on fossil fuels, and energy prices are often subsidized, or government controlled. Huge investments are needed to promote clean and renewable energy. Yet, public expenditure in the region is constrained, and this has been especially compounded by high COVID-19-related expenditures. The intermittency of variable renewable energy (due to clouds and wind speed changes) requires investments not only in renewable energy but also in energy storage, electricity transmission lines, and other infrastructure. The power sector is undergoing significant transition, and variable renewables will be the main building block for low-carbon power systems. Electricity systems will also have to handle the challenges from rising variable renewables. Flexibility is the key to electricity security, which requires timely investments in flexible resources such as dispatchable power plants, grids, demand side, and energy storage. The following solutions were proposed:

  • Stanford University Professor Fran Wolak proposed that short-term market design and a long-term resource adequacy mechanism are crucial for achieving a given renewable energy goal with minimal above-market costs.
  • International Energy Agency Lead Analyst Peerapat Vithayasrichareon proposed varying solutions across six distinct stages of the growing share of renewable energy (RE) in energy systems, depending on the current stage a particular country is at.

Achieving a multilateral regional power market

Regional cooperation for climate change mitigation is needed in many areas, including electricity markets, cross-border renewable energy trade, low-carbon technology transfers, carbon markets, and many others. The panel discussion on this topic identified some key points for regional cooperation on cross-border power trade:

  • Enhancing regional energy connectivity with a focus on power grids is an important means of enhancing the sustainability, reliability, and security of the region’s energy supply.
  • The importance of cross-border power trade to accommodate intermittent renewable energy grows as the share of renewable energy grows.
  • UN ESCAP Chief of Section for Energy Connectivity Matthew David Wittenstein proposed that countries from the same region (such as those from Central Asia or South Asia) work together to plan a multilateral regional power market rather than just bilateral power trade, due to the increased cost savings and efficiency improvements that are expected to grow as the share of renewable energy increases.

Realizing the potential of buildings

The building and manufacturing of building construction materials sectors account for approximately 38% of global GHG emissions and consume 35% of total energy (Figure 1). As University of Birmingham Professor of Cold Economy Toby Peters explained, 20% of all electricity used is in buildings, and cooling accounts for more than 7% of global GHG emissions and is the fastest-growing source of hydrofluorocarbon emissions. The manufacturing of steel and cement, which are widely used as construction materials in buildings, accounts for 14%–16% of global energy-related CO2 emissions (S&P 2021). If the cement industry were a country it would be the third-largest emitter (The Economist 2021). Five countries—the United Kingdom, India, Germany, Canada, and the United Arab Emirates—have pledged to support demand for low-carbon steel, cement, and concrete. Recommendations at the conference included:

  • Green buildings and low-carbon cooling are promising for developing Asia, especially Southeast Asia, due to its climatic conditions.
  • Sustainable solutions for meeting the fast-growing demand for cooling are not just about renewable energy but also include thermal energy storage, passive cooling, and behavioral changes.
  • The promotion of green buildings can provide demand for low-carbon construction materials, such as steel, cement, and concrete, as well as other measures for environmentally friendly construction (such as the 3Rs: reduce, reuse, and recycle).
  • COP26 highlighted the importance of fossil fuel subsidy removals. Subsidies for green (or energy efficient) buildings and energy efficient cooling and heating could be used to provide sustainable support for low-income and vulnerable groups.

Enhancing the resilience of agriculture, forestry, and land use

Agriculture is both a major cause and a victim of climate change. Agriculture and land-use change contribute to about a quarter of global GHG emissions. However, agriculture is very dependent on weather and climatic conditions, making it is the most vulnerable sector. Achieving food and nutritional security for growing populations is severely threatened by climate change. Failure to act quickly to reduce GHG emissions and improve the resilience of the agricultural sector could increase food insecurity, malnutrition, and even lead to famine. Although climate change is pervasive, developing countries suffer the most due to a lack of resources for investing in adaptation. It also disproportionately affects the poorest and vulnerable populations, especially in low- and middle-income countries.

Junhong Chang, Executive Director at the World Bank Group, explained how climate change may push over 130 million into poverty by 2030 and could drive 216 million people to migrate within their own countries by 2050. Proposed solutions for agriculture, forestry, and land use included the following:

  • The agriculture sector requires investment to improve the resilience of smallholder farmers and ensure food security in the light of climate change, environmental degradation, and rising populations.
  • There is a need to expand digital advisory services, access to insurance, finance, markets, and adaptive technologies for smallholder farmers.
  • Policy makers should prioritize scalable, cost-effective, and feasible solutions to get the best out of investment in climate-smart agricultural technology. Forests, as an important component of nature-based climate solutions, present tangible opportunities to significantly reduce GHG emissions.
  • Managing forests to sequester carbon has the combined advantage of producing goods and services while conserving biodiversity and preventing environmental degradation.

Decarbonizing the transport sector

Road transport accounts for over 10% of global GHG emissions, with emissions rising faster than in many other sectors. A declaration to sell only zero-emission transport vehicles (ZEVs) globally by 2040, and by no later than 2035 in leading markets, was signed at COP26 by many governments, local and regional authorities, and automotive companies and investors. These new targets aim to accelerate the transition to ZEVs in a bid to achieve the Paris Agreement’s goals.

Largely due to an increase in income, urbanization, and population, the demand for transport services will increase significantly. Robin Hickman, Professor of Transport and City Planning at University College London, highlighted projections by the International Transport Federation that estimate that by 2050, the number of vehicles globally would increase to 2.4 billion from 1 billion vehicles in 2015. Although battery electric vehicles could be a better alternative to fuel-based automobiles for mitigating air pollution, their higher cost and the lack of ubiquitous charging infrastructure networks are major bottlenecks. Recommendations for decarbonizing the transport sector included:

  • Investment in clean energy technology in the transport sector is crucial to meet the 1.5°C target.
  • Marvin Stolz, Transport Policy Advisor at GIZ, explained that to achieve the 1.5-degree target, the global community should phase out the sale of new internal combustion engine vehicles by 2030, increase walking and cycling to 50% of trips, double public transport capacity by 2030, electrify at least 70% of railways, and prioritize electricity as a primary transport fuel.

Next steps

Greening the energy sector is important, but other sectors, such as the transport, building, and agriculture sectors, also need to play their role in climate change mitigation. Developing Asia has some common barriers and issues, but there are also regional and country-specific disparities due to differences in climatic and geographical conditions, energy market development, and the quality of existing infrastructure. The 2021 ADBI Annual Conference offered many promising solutions, but not all questions could be answered. The remaining challenges include a commonly accepted green finance taxonomy and harmonized carbon taxes. The solutions to these and other issues will require strong regional cooperation and resolve.
