Asian cities are especially susceptible to unpredictable environmental change, as these cities are expected to account for more than 60 percent of global population growth in the next 30 years. Measures that help the urban poor in Asian cities adapt to the changing climate and build their resilience and capacity to respond dynamically to its adverse impacts, are essential, and call for attention, funding and action from civil society, the public and private sectors. Private sector engagement in Urban Climate Change Resilience Building (UCCRB) is particularly important, as the need is vast, and grant funding from governments and donors is limited. This report aims to identify business opportunities in UCCRB, and to understand the drivers and inhibitors to private sector participation.
