Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.

Economics of the Environment: Selected Readings

| 2019

Now in its seventh edition, Economics of the Environment serves as a valuable supplement to environmental economics text books and as a stand-alone reference book of key, up-to-date readings from the field. Edited by Robert N. Stavins, the book covers the core areas of environmental economics courses as taught around the world; and the included authors are the top scholars in the field. Overall, more than half of the chapters are new to this edition while the rest have remained seminal works.

Revitalizing Nuclear Security in an Era of Uncertainty

| January 2019

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

Both energy production and consumption can simultaneously affect regional air quality, local water stress and the global climate. Identifying the air quality–carbon–water interactions due to both energy sources and end-uses is important for capturing potential co-benefits while avoiding unintended consequences when designing sustainable energy transition pathways. The authors examine the air quality–carbon–water interdependencies of China's six major natural gas sources and three end-use gas-for-coal substitution strategies in 2020.

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 Sobering Reasons Congress Must Step Up On Arms Control

| July 19, 2018

Congress is asserting itself by passing additional sanctions to hold Russia accountable for its meddling in U.S. elections. Now it needs to step up its work on arms control — not despite the current tensions with Russia, but because of them.

Trump and Putin Face an Urgent Arms Control Deadline in Helsinki

| July 12, 2018

As US-Russian relations continue to deteriorate, Presidents Trump and Putin appear eager to find common ground on arms control when they meet in Helsinki on Monday. The reason for their urgency is clear: The framework that has stabilized the US-Russian strategic balance since the fall of the Soviet Union is in danger of collapsing.

Climate, Air Quality and Human Health Benefits of Various Solar Photovoltaic Deployment Scenarios in China in 2030

Solar photovoltaic (PV) electricity generation can greatly reduce both air pollutant and greenhouse gas emissions compared to fossil fuel electricity generation. The Chinese government plans to greatly scale up solar PV installation between now and 2030. However, different PV development pathways will influence the range of air quality and climate benefits. Benefits depend on how much electricity generated from PV is integrated into power grids and the type of power plant displaced. Using a coal-intensive power sector projection as the base case, the authors estimate the climate, air quality, and related human health benefits of various 2030 PV deployment scenarios.
