The July 16 summit in Helsinki between Presidents Donald Trump and Vladimir Putin presents a unique opportunity to reverse the dangerous nuclear competition between the United States and Russia and should be welcomed, despite its inherent risks. The opportunity to stabilize U.S.-Russian nuclear relations by extending New START, a key nuclear treaty that is set to expire in 2021, is paramount and worth the issues that come with any meeting between Trump and Putin.

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.

With the world focused on the United States and North Korea, it’s easy to forget that every president for a quarter-century has said preventing nuclear terrorism was a national security priority. This includes the Trump administration, which identified in its Nuclear Posture Review that nuclear terrorism is one of “the most significant threats to the security of the United States.” It appears, however, despite this strong rhetoric, the administration may not be putting its money where its mouth is.

President Trump surprised almost everyone—probably not the least Kim Jong-un—when he agreed to meet the North Korean leader at the end of May (now maybe early June). By accepting Kim’s invitation, President Trump overturned decades of conventional wisdom on how to separate North Korea from its nuclear and other WMD programs. If Trump and Kim meet—as of now this is still a big “if,” although North Korea has now confirmed its willingness to meet directly—the summit could be an important ice breaker and open up a chance to resolve the North Korean nuclear crisis and bring peace to the Korean peninsula. But success, however remote it may seem, will require new thinking and entail major risks. It will also require a plan.

This edited volume provides a fresh analysis for researcher and practitioners regarding United Nations Security Council resolution 1540, the status of its implementation, and its future by providing an original evaluation of progress in implementation and challenges faced during the resolution’s first decade. In doing so, the book will consider the resolution’s utility as a non-proliferation tool with a view to identifying what further actions are required for the objectives and goals embodied by UNSCR 1540 to be achieved and sustained.  The book progresses by exploring the history of the resolution, implementation trends, implementation from a regional perspective, challenges, and future ways forward. The book appeals to a wide readership of scholars, policymakers, and other stakeholders of the 1540 process.

Electric vehicles maintain the fastest development in China and undertake the responsibility of optimizing energy consumption and carbon emission in the transportation field. However, from the entire life cycle point of view, although electric vehicles have a certain degree of energy consumption and carbon emission reduction in the use phase, they cause extra energy consumption and carbon emission in the manufacturing phase, which weakens the due environmental benefits to some extent. The recycling of electric vehicles can effectively address the issue and indirectly reduce the energy consumption and carbon emission in the manufacturing phase. China is setting up the recycling system and strengthening regulation force to achieve proper energy consumption and carbon emission reduction benefits of electric vehicles.

The major global nuclear powers are building up their arsenals once again, sparking fears of a new nuclear arms race. How serious is the danger? We ask Matthew Bunn, former White House adviser on Science and Technology Policy and co-principal investigator from the Belfer Centre on Managing the Atom.

Electrification with decarbonized electricity is a central strategy for carbon mitigation. End-use electrification can also reduce air pollutant emissions from the demand sectors, which brings public health co-benefits. In this article, the authors focus on electrification strategies for China, a country committed to both reducing air pollution and peaking carbon emissions before 2030. Considering both coal-intensive and decarbonized power system scenarios for 2030, they assess the air quality, health, and climate co-benefits of various end-use electrification scenarios for the vehicle and residential sectors relative to a non-electrified coal-intensive business-as-usual scenario.
