Asian cities currently contribute 80 percent of Asia’s economic activity and account for
54 percent of the region's carbon emissions. By 2050, Asia’s urban population could grow by 1.1
billion and reach 3.4 billion, which is the equivalent size of today’s global urban population. In
the absence of significant climate adaptation measures, the most significant increase in energy
consumption and green house gas emissions is expected to take place in Asian mega-cities.
Existing infrastructure and urban development pathways could lock cities into unsustainable
growth and consumption models, with worsening impacts on climate change. Hence, smart and
effective urbanization is the order of the day and all measures need to be put in place to make the
Asian cities smart, robust, livable keeping in mind the global issues of climate change. The
future expansion of urban areas on agricultural lands and forests could also lead to the
destruction of natural carbon sinks and important climate adaptation systems. Limiting climate
change therefore means decarbonizing Asian cities. The good news is that there is a strong value
proposition for Asian cities to accelerate their decarbonisation. Physical climate risks and their
associated social and economic costs are already significant. Their impact, if unmitigated, could
increase substantially, and have a material effect on Asia’s 597 million urban poor. As the
majority of Asia’s economic activity takes place in cities and urbanization is still progressing
fast, there is a significant opportunity to increase resource efficiency and transform Asian urban
growth models to make them more circular, regenerative, and inclusive. It is seen that the Asian
cities contribute significantly to climate change, urban population growth creates opportunities to
decarbonize at scale, and that Asian cities are also exposed to climate risks.
