Abstract:
The Harvard Initiative to Reduce Global Methane Emissions released its first publication in May 2023: a research brief titled “Updating Estimates of Methane Emissions: The Case of China.” The Initiative is one of five interdisciplinary research clusters funded by the Salata Institute for Climate and Sustainability at Harvard University. The Harvard Project on Climate Agreements collaborates in the implementation of the Initiative. The brief summarizes research by Professor Daniel Jacob and postdoctoral fellow Zichong Chen, atmospheric scientists at Harvard University, with their colleagues. Jacob and Chen use high-resolution data from the TROPOspheric Monitoring Instrument (TROPOMI), onboard a satellite launched in 2017, to estimate national and sectoral methane emissions more accurately than has been possible in the past. They draw upon atmospheric transport models to invert the satellite observations of methane concentrations, using advanced statistical methods, and infer emissions quantities and locations from the observed atmospheric concentrations. This method has yielded generally higher estimates of emissions than in previous reports, including in the case of China. Future methane-initiative briefs will address similar research the authors and their colleagues are conducting in the United States, Latin America, North Africa, and other countries and regions. An accurate picture of aggregate and sector-level methane emissions is important to better target mitigation policies. It is hoped that the results of the research described here and in subsequent briefs will advance national efforts and international collaboration aimed at reducing methane emissions. The Harvard Initiative to Reduce Global Methane Emissions seeks meaningful and sustained progress in global methane-emissions reductions through research and effective engagement with policymakers in government and key stakeholders in business, nongovernmental organizations, and international institutions. Reduced methane emissions can significantly reduce, in the near term, the magnitude of climate change and its associated impacts. The Initiative’s objectives span the full range of disciplines and topics associated with this challenge. Among its objectives are to build on scientific research on measurement and attribution of emissions; understand legal, regulatory, and political opportunities and constraints to methane-emissions reductions in the United States; design policies that might best contribute to methane emissions reduction; work effectively through existing international venues, such as the United Nations Framework Convention on Climate Change; and define roles that business and international and multilateral organizations can play in this effort.

2. Outsiders Wanting In: Asian States and Arctic Governance

Abstract:
The strategic interests of Asian countries in the Arctic continue to grow despite the disruptions of the COVID-19 pandemic and the geopolitical fallout of Russia’s invasion of Ukraine. China and India have their eye on Russia’s Arctic energy resources, and China is further seeking to leverage Russian weakness to expand its operational presence in the Arctic Ocean. Japan, South Korea, and Singapore are less prominent in Arctic regional institutions, yet they have distinctive interests in Arctic science, governance, and resources and are resuming dialogue about Arctic matters amongst themselves. This policy brief reviews the key differences in how Asian states are approaching the Arctic through a survey of their strategic documents, public statements, and diplomatic and commercial activities.

3. China’s Rise and U.S. Defense Implications

Abstract:
What are the international implications of China’s rise? What developments may be expected, and what should U.S. national defense leaders do about the likely effects of these developments? China is a rising power but even if that cannot be said to translate into a security threat to the United States directly, there is little reason to believe that Beijing will not take action to get out from under what it perceives as unfriendly U.S.-led global diplomatic, economic, and security orders. In very broad terms, U.S. defense policy makers will need to address the change from military capabilities for enforcing a liberal international order, to capabilities for both advancing and protecting friendly regional or even sub-regional orders. China’s potential power is sizable and increasing based on a large population and growing national wealth and this potential power makes its neighbors fear that it will become the regional hegemon. Since other states in the region cannot predict if or when Beijing will make a bid for hegemony, relations are beset with uncertainty. Weaker neighbors, like Vietnam and Laos in Southeast Asia, can be expected to accommodate Beijing more while trying to benefit from Chinese economic growth when and where possible.1 The U.S. security allies can be expected to cooperate more with each other while calling for more visible displays of U.S. commitment (including more military force presence).2 India will become more important to U.S. strategy as a link between Australia and Thailand, and the Middle East and Central Asia, and the Pacific and Indian Oceans.

4. China: The Renewable Hydrogen Superpower?

Abstract:
President Xi Jinping’s pledge during the 2020 United Nations General Assembly, that China would reach peak carbon dioxide emissions by 2030 and achieve carbon neutrality before 2060, is a significant step in the fight against climate change. Since China is the world’s top contributor of greenhouse gases, there is no doubt that Beijing needs to be front and center of any effort to curb global emissions. In 2019, China accounted for almost 30 percent of global emissions, about twice as much as the second largest emitter, the United States.1 But while U.S. emissions have been on an overall decline since 2007,2 China’s have increased, raising concerns over whether Beijing can actually deliver on its targets. This reality should not distract from the fact that China is also the world’s top developer of renewables and other clean energy technologies. For example, China was the world’s largest installer of photovoltaics (PV) by 2013 and, in less than two years, also became the global leader in solar module manufacturing. At the same time, China leveraged its industrial might and economies of scale to drive down modules’ costs—which, by the end of 2018, were 90 percent lower than only ten years before. In this context, renewable hydrogen could significantly accelerate China’s transition to a low-carbon economy, increasing the likelihood of meeting its carbon neutrality goal. Renewable hydrogen offers significant advantages for China. It can help Beijing meet its climate and pollution goals—at a time when coal continues to dominate—while avoiding increased reliance on imported fuels. As a readily dispatchable means of storing energy, hydrogen can help to address intermittency and curtailment issues as renewable energy increases its share of China’s energy mix. As a sustainable mobility energy carrier, it can power fuel-cell electric vehicles or be the base for synthetic fuels. Finally, renewable hydrogen can open new avenues for developing clean technology manufactured goods for both internal and export markets. Today, most of China’s hydrogen is produced from coal via 1,000 gasifiers, accounting for 5% of the country’s total coal consumption. Hydrogen costs vary significantly as a function of production technology and prices of fossil fuels and electricity. Production from coal remains the lowest cost option: about 30 percent cheaper than hydrogen from natural gas. Therefore, reducing the carbon footprint of coal-based hydrogen will be critical in a low-carbon economy. In the medium term, coal-based hydrogen with carbon capture, utilization and storage will likely remain China’s lowest-cost clean hydrogen production pathway. Hence, the underlying question is whether Beijing will prioritize cost considerations or put its full industrial might behind the development and deployment of renewable hydrogen. In March 2019, the Chinese government took a significant step forward by announcing measures to promote the construction of hydrogen facilities for new energy vehicles. Wan Gang, who is known as China’s “father of the electric car,” called for China to “look into establishing a hydrogen society” and “move further toward fuel cells.”3 Given that Gang made a similar call two decades ago on vehicle electrification, which played a key role in China’s current battery electric vehicles market dominance, close attention is warranted.
