Joel Clement writes that because the Biden administration  has moved to repair the damage done by the Trump administration, colleagues from around the global Arctic are optimistic once again about partnering with America on solutions to regional crises .

A large part of operating costs in urban water supply networks is usually due to energy use, mostly in the form of electricity consumption. There is growing pressure to reduce energy use to help save operational costs and reduce carbon emissions. This study shows how a hybrid linear and multi-objective optimization approach can be used to identify key energy consumption elements in a water supply system, and then evaluate the amount of investment needed to achieve significant operational gains at those points in the supply network.

The Belt and Road Initiative (BRI) is an important cooperative framework that increasingly affects the global economy, trade, and emission patterns. However, most existing studies pay insufficient attention to consumption-based emissions, embodied emissions, and non-CO2 greenhouse gases (GHGs). This study constructs a GHG emissions database to study the trends and variations in production-based, consumption-based, and embodied emissions associated with BRI countries

Harvard University has created a Presidential Committee on Sustainability (PCS) to advise President Larry Bacow and the University's leadership on sustainability vision, goals, strategy, and partnerships. The Harvard Gazette spoke with committee chairs Rebecca Henderson, the John and Natty McArthur University Professor; John Holdren, the Teresa and John Heinz Professor of Environmental Policy at Harvard Kennedy School; and Katie Lapp, executive vice president, about why it is so important to act now; the role of the PCS in developing collaborative and innovative projects; and how the campus community can get involved.

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.

The Policy and Action on Plastic in the Arctic Ocean workshop was held at the Harvard Kennedy School on 30–31 October 2019. The speakers' bios and presentations are now available.

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 Arctic Transformation and Resilience Study Group, led by Arctic Initiative Senior Fellow Joel Clement, will give students the opportunity to learn about and work on issues of Arctic resilience. Working together to deliver a compilation and brief analysis of existing policies that support or inhibit resilience in the Arctic, students will have the opportunity to meet with top Arctic scientists, policymakers, indigenous knowledge-holders, and finance experts, while developing a report that will be delivered to the Secretariat of the Arctic Council Sustainable Development Working Group.

This study group will be held on Tuesdays, from 6pm–7:30pm, beginning Oct 29, and including Nov 5, 12, 19, and 26. For more information or to sign-up, please contact brittany_janis@hks.harvard.edu. Space is limited; please register by October 21.

Bruce Schneier  explains that there is no escaping the technology of inevitable surveillance. Consumers have little choice but to rely on the companies that build their computers and write their software, whether in  smartphones,  5G wireless infrastructure, or subway cars.  China is more likely to try to get data from the U.S. communications infrastructure like the United States does rather than try to produce a subway car outfitted with surveillance apparatus.

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.
