The data suggest that greater focus on sustainable outcomes and social development at every income level is consistent with reduced pollution. Furthermore, a continued transition toward energy efficiency and alternative sources is relevant in reducing long-term emissions at lower income levels. Under this assumption, pollution reduction is most economically achieved by simultaneously developing the economics, environment and social programs of a society. These findings are substantial for devising long-term policy. However, no amount of data signifying the long-term economic benefits of environmentally sustainable planning will suffice unless the legitimacy of global warming, and the ability of human intervention to contradict the problem is recognized by those having decision-making power.
