An internationally coordinated carbon tax could raise $250 billion annually, while a small financial-transaction tax could raise another $40 billion. Likewise, regular SDR emissions to keep pace with the growth of global liquidity could yield roughly $100 billion annually for international development cooperation.
全球协调的碳排税每年能筹集2500亿美元，而低额金融交易税也能筹集400亿美元。类似地，根据全球流动性定期释放SDR能为国际发展合作带来每年1000亿美元的资金。这一资金释放将减少对美国国债和其他首选货币计价流动资产的需求。
