| Dec. 13, 2018

The critical role that market mechanisms can play in international global climate change efforts was the focus of discussion Tuesday (Dec. 11) at an official side event at the 24th meeting of the United Nations Framework Convention on Climate Change (UNFCCC) Conference of the Parties (COP) in Katowice, Poland. The event, “Elaborating and Implementing Article 6 of the Paris Agreement,” was co-hosted by the Enel Foundation and the Harvard Project on Climate Agreements. It attracted more than 200 audience members inside the Pavilion, and thousands of others viewing the live webcast around the world.

Policy Evolution Under the Clean Air Act

| November 2018

The U.S. Clean Air Act, passed in 1970 with strong bipartisan support, was the first environmental law to give the Federal government a serious regulatory role, established the architecture of the U.S. air pollution control system, and became a model for subsequent environmental laws in the United States and globally. We outline the Act’s key provisions, as well as the main changes Congress has made to it over time. We assess the evolution of air pollution control policy under the Clean Air Act, with particular attention to the types of policy instruments used. We provide a generic assessment of the major types of policy instruments, and we trace and assess the historical evolution of EPA’s policy instrument use, with particular focus on the increased use of market-based policy instruments, beginning in the 1970s and culminating in the 1990s.

GHG Cap-and-Trade: Implications for Effective and Efficient Climate Policy in Oregon

| November 2018

Like many other states, Oregon has begun to pursue climate policies to attempt to fill the gap created by the lack of effective climate policy at the Federal level. After adopting a variety of policies to address climate change and other environmental impacts from energy use, Oregon is now contemplating the adoption of a greenhouse gas (GHG) cap-and-trade system. However, interactions between policies can have important consequences for environmental and economic outcomes. Thus, as Oregon considers taking this step, reconsidering the efficacy of its other current climate policies may better position the state to achieve long-run emission reductions at sustainable economic costs.

Governing Cooperative Approaches under the Paris Agreement

    Author:
  • Michael A. Mehling
| November 2018

This paper draws upon research, practical experience with carbon trading, textual analysis, negotiating history, and insights from stakeholders to develop principles that can help inform the elaboration of cooperative approaches set out in Article 6.2 of the Paris Agreement — and thereby enhance opportunities for ambitious mitigation. The author, Michael A. Mehling, explores, in particular, how operational guidance for implementing Article 6.2 can balance environmental ambition and flexibility in governance.

An Economic Anatomy of Optimal Climate Policy

| August 2018

The authors introduce geoengineering into an optimal control model of climate economics. Together with mitigation and adaptation, carbon and solar geoengineering span all possible climate policies. Their wildly different characteristics have important implications for policy. They show in the context of their model that: (i) whether emissions are positive or zero the optimal carbon tax always equals the marginal cost of carbon geoengineering; (ii) the introduction of either form of geoengineering leads to higher emissions yet lower temperatures; (iii) in a world with above-optimal cumulative emissions, mitigation alone is insufficient and only a complete set of instruments can minimize climate damages.
