Commitments on adaptation in the Paris agreement would go a long way toward closing this gap. The international auctioning of emissions allowances and allowances in domestic emissions-trading schemes, a carbon tax, revenues from international transport, a surcharge on electricity transmission, and financial transaction taxes could generate as much as $220 billion per year in additional revenues.
巴黎协议中的适应承诺将极大地有利于填补这一缺口。国际排放许可拍卖和本国碳排交易机制、碳税、国际转移支付收入、输电附加费和金融交易税将能产生每年2,200亿美元的新增收入。
