In other words, global rules and institutions can make it easier and more likely that all involved will hew to their own citizens’ broader interests – and thus to the global commonweal as well. For example, pledges to cut carbon emissions, while lacking any enforcement mechanism, may be helping countries to do the right thing for their own citizens’ children and grandchildren.
换句话说，全球规则和机构令所有各方都可以更容易也更乐意去维护本国公民的更广泛利益——以及因此产生的全球福利。例如削减碳排放的承诺虽然缺乏任何强制执行机制，却可能有助于让各国为自己的子孙后代做出正确的行动。
