      "content": "- Carbon pricing:\n  - Is necessary but not always sufficient to reduce emissions.\n  - Should be an integral part of any policy package.\n  - Political hurdles can be overcome, as shown by experiences in Chile, Singapore, and Sweden.\n- Complementary measures:\n  - Carbon pricing should be complemented by other mitigation instruments to address market failures and promote innovation and deployment of low-carbon technologies.\n  - A pragmatic and equitable proposal calls for an international carbon price floor, differentiated across countries at different levels of economic development.\n  - Associated carbon revenues could be partly shared across countries to facilitate the green transition.\n- Just transition and redistribution:\n  - Robust fiscal transfers to vulnerable households, workers, and communities are needed as part of a just transition.\n- Fiscal management:\n  - Governments must enhance spending efficiency.\n  - Governments must build greater capacity for raising tax revenues by broadening the tax base and improving fiscal institutions.\n- Sequencing and timing:\n  - An appropriate mix and sequencing of revenue- and spending-based climate measures enacted now can limit fiscal costs.\n  - Delays in implementing carbon pricing increase debt burdens materially (\"0.8 percent to 2 percent of GDP to public debt for each year of delay\")."
