This publication examines the enormous potential for scaling up green business development in Asia and the Pacific. It reviews green markets, technologies, and practices with a focus on developing Asian countries and offers a set of policy options to enable governments and finance institutions to accelerate green business development in the region. Direct command-and-control measures and indirect market-based instruments targeted at both large and small firms are also included. The analysis suggests that advancing green businesses is a win–win for all stakeholders, but requires mobilizing vast resources of private capital and innovative management approaches.
