East Asia is helping the rest of the world decarbonize and encouraging the domestic adoption of renewables. But there is an imbalance: even as the region’s innovation and investment significantly improve global access to green technologies, its own emissions continue to grow because of the reluctance to penalize carbon-intensive technologies. The disparity between domestic supply and demand also spills over into international trade, provoking measures that limit access to markets and technologies. Deeper reform of the region’s own policies may foster greater international cooperation on climate change, innovation, and trade in green goods.
