Arunabha Ghosh, an internationally recognized public policy expert, author and columnist is the founder-CEO of the Council on Energy, Environment and Water (CEEW), one of Asia’s top climate think-tanks. In numerous reports, articles and speeches, Dr. Ghosh has convincingly argued that confronting the challenges of climate change will require better policies at the national level and massive levels of cooperation between government and businesses and between nation states across international borders. We will need to address the linkages between the growth of renewable energy and our changing geopolitical landscapes, the role of investment and finance in creating a green future, and persuade ourselves that pessimism at the lack of progress in reducing emissions is not an option. A green future is not an end in itself, but rather the means to an end: a more prosperous and secure future for all. The time to act is now.
