Science, Technology, and Public Policy

This brief examines the national challenges related to deploying and scaling infrastructure to transport CO₂ from capture sites to storage or utilization sites at a scale consistent with achieving net-zero by 2050.

If the world is serious about addressing climate change, we should welcome forward momentum on this critical technology. Getting on track for net zero emissions by 2050 will require swiftly and massively ramping up carbon capture deployment.

Carbon capture, utilization, and storage (CCUS) is very likely to be a key technology for achieving the Biden administration's goal of net-zero greenhouse gas emissions by 2050. But absent regulation requiring its use, CCUS needs to become more economical in order for deployment in the United States to expand significantly.

How can China make good on its pledge to reach carbon neutrality by 2060? In Foundations for a Low-Carbon Energy System in China, a team of experts from China and the United States explains how China's near-term climate and energy policies can affect long-term decarbonization pathways beyond 2030, building the foundations for a smoother and less costly national energy transformation.

Over the last two decades, there has been a dramatic increase in the popularity of financial sanctions as an instrument of US foreign policy to address security threats ranging from weapons of mass destruction (WMD) proliferation and terrorism to human rights violations and transnational crime. Washington’s policymakers have prized these tools for their ability to rapidly apply pressure against foreign targets with few perceived repercussions against American business interests. The problem, however, is that Washington is ignoring a growing tension between financial sanctions designed to support economic statecraft (with non-financial goals) and those designed to protect the international financial system. Confusing the two sends mixed signals to adversaries as well as allies and undermines US credibility and commitment to upholding international banking rules and norms. If Washington cannot reconcile these competing processes, it is unlikely that future administrations will enjoy the same foreign policy levers, leaving the United States at a significant disadvantage.

In this report, the authors conduct a benchmarking analysis for energy and CO2 emissions intensity of the steel industry among the largest steel-producing countries.

Cement production is one of the most energy-intensive and highest carbon dioxide (CO2) emitting manufacturing processes. The goal of this study is to develop a roadmap for decarbonization of California's cement and concrete production. In this study, the authors look at the current status of cement and concrete production in California and develop scenarios up to 2040 to analyze different decarbonization levers that can help to reduce CO2 emissions of cement and concrete production in California.

The United States and Iran have engaged in a constant raising of the stakes as a means of securing leverage ahead of possible nuclear negotiations. This is a classic bargaining pattern but in the current context, such an approach is particularly risky due to the potential for misperceptions. The complexities of domestic and regional dynamics are also a factor. In such a situation, absent clear understanding of the other’s motivations and tactics, raising the stakes—rather than securing leverage for effective negotiations—could steer the United States and Iran towards a path toward war.

Although Trump did not outline his legal basis for imposing the tariffs, several analysts anticipated that he was seeking to use the authorities granted him under the International Emergency Economic Powers Act—the legal basis that presidents rely on to impose financial and economic sanctions against WMD proliferators, terrorist organizations, narco-traffickers, and human rights abusers. Mixing trade and immigration policy under the guise of a national security threat, however, may end up deflating Trump’s “maximum pressure” sanctions campaigns against Iran and North Korea.

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.
