Governance of the Deployment of Solar Geoengineering

The Harvard Project on Climate Agreements has released a volume of 26 briefs that explores a range of topics related to how we might govern the deployment of solar geoengineering.

Russia's Energy Foray into Asia: Implications for U.S. Interests

This essay examines Russia’s growing role in Asia’s energy markets, assesses the implications for the U.S., and examines the claim that closer Sino-Russian energy ties are adding new incentives for a broader strategic alignment.

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.

Governance of Highly Decentralized Nonstate Actors: the Case of Solar Geoengineering

| November 2018

We here introduce the idea of highly decentralized solar geoengineering, plausibly done in form of small high-altitude balloons. While solar geoengineering has the potential to greatly reduce climate change, it has generally been conceived as centralized and state deployed. Potential highly decentralized deployment moves the activity from the already contested arena of state action to that of environmentally motivated nongovernmental organizations and individuals, which could disrupt international relations and pose novel challenges for technology and environmental policy. We explore its feasibility, political implications, and governance.

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.

Harvard-Tsinghua Workshop on Low-Carbon Development and Public Policy

| September 2018

The Belfer Center’s Environment and Natural Resources Program and the Center for Science, Technology, and Education Policy at Tsinghua University held the fifth annual Tsinghua-Harvard Workshop on Low-Carbon Development and Public Policy. This event brought together leading experts on climate and energy from academic, business, and government communities in both the United States and China. This year’s workshop focused on electricity systems and renewable energy penetration.

The Collapse of Civilizations

| September 2018

Five causes of collapse appear paramount: major episodes of climate change, crises-induced mass migrations, pandemics, dramatic advances in methods of warfare and transport, and human failings in crises including societal lack of resilience and the madness, incompetence, cultic focus, or ignorance of rulers.
