      "heading": "Mitigating climate change: policy design and international participation",
      "content": "- Policy robustness to uncertainty is essential; example:\n  - Under a quantity-based scheme (cap and trade), faster-than-expected economic growth raises abatement costs, making original targets hard to achieve and weakening incentives for participation.\n  - Costs increase would be considerably smaller under a price-based scheme (a carbon tax), or a \"hybrid\" scheme that converts a quantity-based scheme into a price-based plan using a safety valve if abatement costs rise above a certain threshold.\n- International competitiveness is a critical consideration for business sectors evaluating participation in international agreements.\n- Advanced economies should lead mitigation efforts, but participation of developing economies is crucial.\n- Proposed international approach highlighted:\n  - Combine strong individual emissions targets for developed countries with trading schemes open to developing countries.\n- Policy context:\n  - These issues are likely to remain high on the international policy agenda as countries debate the future of the Kyoto agreement, set to expire in 2012."
