Direct air capture (DAC) is a type of technology that captures carbon dioxide directly from the air. As the negative impacts of climate change become ever more apparent, governments and private industries have funneled increasing support toward DAC as a critical pathway toward achieving a net-zero future. Although a promising technology, wide-scale deployment of DAC faces several significant challenges.

In recognition of the urgency of reducing methane emissions, several voluntary international multiparty agreements and initiatives have recently been concluded to accelerate collective action and establish formal mechanisms for monitoring the implementation of methane-related commitments. While these initiatives reflect ambition on the part of public, private, and civil society actors with regard to methane, the implementation of these initiatives presents challenges for governments, emitting sectors, and other parties.

As governments, firms, and universities advance ambitious greenhouse gas emission goals, the demand for emission offsets — projects that reduce or remove emissions relative to a counterfactual scenario — will increase. Reservations about an offset’s additionality, permanence, double-counting, and leakage pose environmental, economic, and political challenges. The authors review the role of offsets in regulatory compliance, as an incentive for early action, and in implementing voluntary emission goals

India plays a critical role in global climate and energy policy. Although India is only responsible for 7% of global greenhouse gas emissions today, it has a large population and considerable potential for rapid economic growth. This paper explores how India’s states can best address climate change, the relative roles of state and Union governments, and how relationships between states and New Delhi can constrain or accelerate climate action.

This discussion paper explores key areas of disagreement on Article 6 and explores possible outcomes from the upcoming Conference of the Parties to the United Nations Framework Convention on Climate Change (COP-26) in November 2021 in Glasgow.

Guangdong Province ranks first in economic output among China’s provinces and will play a major role in achieving China’s national climate-change goals. This paper examines the progress of Guangdong Province’s carbon dioxide emissions trading system (ETS) in reducing emissions; design features of the system; challenges it faces with regard to further development; and its relationship to China’s new national ETS.

There are potential roles for sub-national climate policies in addressing climate change. Theory and experience of nesting sub-national climate policies within a broader, national climate policy indicate that the interactions between the two levels of governance can be problematic, benign, or positive, depending upon the nature, design, and stringency of the policies. When the national system is a tradable performance standard, as with China’s national system, the consequences are similar to those with cap-and-trade, but more complex.

China’s emissions trading system (ETS) for carbon dioxide (CO₂) will become operational in mid-2021. This paper describes the trading system’s history, design, rules governing implementation, and anticipated developments over the next decade. The ETS is expected to support China’s goals of reaching peak CO₂ emissions by 2030 and of achieving carbon neutrality by 2060.

Donald Trump’s 2016 election and his nomination of climate skeptic Scott Pruitt to head the Environmental Protection Agency drastically downshifted expectations on U.S. policy toward climate change. Joseph Biden’s 2020 election shifted them dramatically upward. The authors study firms’ stock-price movements in reaction. As expected, the 2016 election boosted carbon-intensive firms. Surprisingly, firms with climate-responsible strategies also gained, especially those firms held by long-run investors. Such investors appear to have bet on a ‘‘boomerang’’ in climate policy. Harbingers of a boomerang already appeared during Trump’s term. The 2020 election marked its arrival.

By investing in the public and private sector research and development in this space, and by fostering a community of researchers, entrepreneurs, and investors literate in CO2 capture opportunities, the United States can be the leader of this new economic sector. It is essential for the Nation to build a vibrant and sustained research and development community spanning the public sector, academic and research domains, and for-profit companies, ensuring world leadership in this new technological domain.
