Climate Change and Sustainability

8pm Singapore | 9pm Tokyo

Massive flooding in Germany. Typhoons in Asia. Heatwaves and wildfires in Europe, Australia and North America. Even as climate impacts intensify and affect more people, goals like net zero emissions and limiting global warming to 1.5˚C seem more and more unreachable. What are the decisions and policies now required from all levels of government to combat climate change?

With COP26 still fresh in the mind, how should policymakers, policy professionals and students of public policy now approach the climate problem? Should we look to governance, trade or diplomacy to move the needle? Will sustainability emerge as a new ‘organising principle' of policy? If so, what might that practically mean?


Hear from and question thinkers and practitioners who have negotiated climate pacts, advised world leaders and authored seminal works on climate, sustainability, energy and the environment.
