确保国际转让减缓成果的环境完整性，无论是通过抵消安排、市场机制还是非市场方式，都是落实《巴黎协定》第六条的优先事项。任何传统的转移缓解成果，例如涉及交换不同寿命的温室气体的抵消协议，都可能在某些时间尺度上加剧全球变暖。我们表明，关于选择此类交易中使用的指标的简单“不伤害”原则可以用来防止这种情况，并指出它也可能适用于其他情况，例如自愿和合规碳市场。我们还表明，近似和精确的“变暖当量”交换都是可能的，但在任何传统市场中实施都面临挑战。然而，变暖当量排放量可能有助于以两篮子缓解方法制定变暖预算，并在全球盘点的背景下报告对变暖的贡献。
Ensuring the environmental integrity of internationally transferred mitigation outcomes, whether through offset arrangements, a market mechanism or non-market approaches, is a priority for the implementation of Article 6 of the Paris Agreement. Any conventional transferred mitigation outcome, such as an offset agreement, that involves exchanging greenhouse gases with different lifetimes can increase global warming on some timescales. We show that a simple ‘do no harm’ principle regarding the choice of metrics to use in such transactions can be used to guard against this, noting that it may also be applicable in other contexts such as voluntary and compliance carbon markets. We also show that both approximate and exact ‘warming equivalent’ exchanges are possible, but present challenges of implementation in any conventional market. Warming-equivalent emissions may, however, be useful in formulating warming budgets in a two-basket approach to mitigation and in reporting contributions to warming in the context of the global stocktake.
