Without adequate mitigation and adaptation efforts, climate risks will become a growing constraint to China’s long-term growth and prosperity, threatening to reverse development gains. Conversely, if efforts to tackle climate risks lead to a significant decline in growth and rising inequality, they would deprive millions of people of development and likely erode support for the reforms necessary to achieve a lasting economic transformation. Hence, China will need to grow and green its economy at the same time. This report offers policy options to achieve these dual objectives by easing inevitable trade-offs and maximizing potential synergies between China’s development and climate objectives. Table O.1.
