Global leaders are gathered in Paris for the COP21 climate summit. Given Asia Pacific’s size and its contribution to global greenhouse gas emissions, its voice and commitment are critical to achieving a comprehensive agreement on climate change.

Many Asia Pacific countries are developing and must focus on achieving sustained economic growth and development. Of the 49 regional members of the United Nations Economic and Social Commission for Asia and the Pacific, 43 have a light climate footprint, contributing only 10 percent to global emissions. For these countries, notably the least developed countries, Pacific islands and low-lying states, vulnerability to climate-related natural disasters will grow with climate change. At the other extreme, the region is home to six of the top 10 emitters in the world – China, India, Russia, Japan, Indonesia, and Iran – which account for about 43 percent of global emissions. Of these top six Asian emitters, fossil fuel-based energy is responsible for about 80 percent of their collective emissions, with emissions from industrial processes, agriculture, and waste playing a lesser role. Mitigating the emissions of these countries requires multiple actions, key among which is a switch from fossil fuels to renewable energy sources.

Of the 183 countries that have submitted Intended Nationally Determined Contributions (INDCs) to the United Nations Framework Convention on Climate Change, 43 are from the Asia Pacific region. Countries across the region have indicated both conditional and unconditional reductions of greenhouse gas emissions. These include economy-wide emissions targets or deviation from a business as usual (BAU) scenario to intensifying targets for emissions per unit of GDP. Many INDCs, particularly those from the developing countries, include an overall rise in emissions by 2030.

While this is remarkable in its own right, it still leaves a significant gap between the INDCs pledged and the cuts required to keep the temperature increase to below a two degrees Celsius warming limit. This gap is close to 16 billion tons of CO2 reductions per annum by 2030, roughly equal to the current emissions of China, India, and Russia combined. The only way we can bridge this gap is if we collectively treat the INDCs announced as the floor to be raised by enabling countries to adopt and implement additional measures needed with technical, financial, and capacity support.

Despite the present gap between the INDCs and the necessary emission reductions, progress is underway in our region. This not only sets specific economies on course for a low carbon future, but will also alter the global dynamics. China’s INDC, for instance, targets emissions to peak by 2030 at the latest, and for emissions intensity of GDP to decline by 60 to 65 percent. Progress in energy efficiency, switching to gas and the development of hydro, wind, and solar energy has now begun to show results, with China’s coal consumption having peaked in 2013. India proposes to reduce emissions per unit of GDP by 33 to 35 percent, and to ensure that 40 percent of its power generation capacity is from non-fossil sources by 2030. In support of this objective, India plans to install 60 gigawatts of wind power and 100 gigawatts of solar power capacity by 2022, a six-fold increase over the current capacity.

Changes in the energy generation mix, efficiency and conservation of energy use, and developing carbon sinks through reforestation and soil carbon will be important strategies to stabilize emissions in the Asia Pacific region. There has been some progress on all these fronts in our region, but more needs to be done. With advanced energy efficiency, the region could save 35 percent of its energy consumption against business as usual by 2035. As the region’s urban population is expected to reach 3.2 billion by 2050, there is an opportunity to pioneer low-carbon cities with energy efficient buildings, innovative urban planning, and efficient transportation systems. There is also a need to switch from coal to renewables and to promote cleaner coal technologies, as coal still accounts for 55 percent of electricity generation in the Asia Pacific. In adopting clean energy alternatives countries are also addressing the scourge of air pollution, which has emerged as a grim reality for many city dwellers across the region. While non-hydro renewables such as wind and solar currently contribute less than two percent of regional electricity generation, growth has been rapid from a small base. The expected shift to renewables will be a net benefit for Asian economies. It will reduce dependence on imported fuels as the region is a net energy importer, enhance energy security and improve the balance of payments. To harness a low carbon future, the region needs to further tap its tax potential, which could be raised by five percent of GDP. This would potentially mobilize 1.5 trillion USD while private sector savings in the region are close to six trillion USD.

The success of the COP21 climate summit is critical for all of us, as climate change does not respect boundaries and no one can escape its effects. Country submissions for emission reduction are a good starting point but remain nonbinding targets. The steep growth in energy demand in the Asia Pacific means more will need to be done to increase the overall penetration of renewable energy in the coming decades, with collective and concerted actions critical to addressing the problem at its source. The future of our region and indeed of our planet hinges on the Asia Pacific region mobilizing its skills and resources to find enduring solutions.
