Many firms are making net-zero and carbon neutral pledges. In principle, these pledges should help consumers identify sustainable options, but often they do not correspond to meaningful actions. In response, both in the U.S. and in Europe, courts and policymakers are requiring firms to disclose...

Regulatory uncertainty has been inherent to climate change in the absence of a successor to the Kyoto Protocol and with ongoing policy discussions on how to proceed. To facilitate steps to help address the issue, many companies have called for more certainty and a stable policy framework. What...

An appropriately conceived and well-designed border climate adjustment scheme, as a policy mechanism potentially utilizable by many States party to the United Nations Framework Convention on Climate Change, may lead to desirable consequences for the development of comprehensive global greenhouse...

Climate cooperation increasingly looks like individuals reaching out beyond traditional interactions to expand new networks, work with others to spot patterns, and take initiative to learn new complex systems; adapt these shared insights into new solutions; develop empathy, patience, and...

We analyze a dynamic multi-pollutant problem where abatement costs of several pollutants are not separable. The pollutants can be either technological substitutes or complements. Environmental damage is induced by the stock of accumulated pollution. We find that optimal emission paths are...
