Decisions taken under the Paris Agreement of the UNFCCC do not clarify how the principle of equity is to be operationalized. Proper consideration of different national circumstances is of paramount importance when designing any multilateral agreements, such as the Paris Agreement . Here, a methodology is presented that implements the equity principle in sharing the global climate budget among countries on the basis of their national circumstances identified by socio-economic factors such as the population size, the per-capita gross domestic product and the current net GHG emission, and physical factors such as the population density and the average temperature. The historical responsibility for net GHG emission since 1990 is dealt with by the financial commitments made by developed countries. The impact of international trade on actual net GHG emission associated with consumption of goods is deemed compensated by the carbon rights underlying the production of such traded goods. Results obtained show that without a consideration of national circumstances, large emitters can claim a larger quota. Nevertheless, national circumstances change over time because of social and economic development as well as because technological improvements. Consequently, quotas have to be recalculated over time (e.g. at each global stocktake).

根据《气候公约》《巴黎协定》作出的决定并未阐明如何实施公平原则。在设计任何多边协定（例如《巴黎协定》）时，正确考虑不同的国情至关重要。在这里，提出了一种方法，该方法在国家根据人口数量，人均国内生产总值和当前温室气体净值等社会经济因素确定的国情基础上，在各国之间共享全球气候预算时实施了公平原则。排放以及人口密度和平均温度等物理因素。自1990年以来，温室气体净排放的历史责任由发达国家作出的财政承诺来处理。国际贸易对与商品消费有关的实际净温室气体排放量的影响被认为是由此类贸易商品生产所依据的碳权所补偿的。获得的结果表明，在不考虑国情的情况下，大型排放国可以要求更大的配额。然而，由于社会和经济发展以及技术进步，国情随时间而变化。因此，配额必须随时间重新计算（例如，每次全球盘点时）。由于社会和经济发展以及技术进步，国情随时间而变化。因此，配额必须随时间重新计算（例如，每次全球盘点时）。由于社会和经济发展以及技术进步，国情随时间而变化。因此，配额必须随时间重新计算（例如，每次全球盘点时）。
