Hydropower is the largest source of low-carbon electricity in the world today. And its benefits are needed more than ever. The International Energy Agency estimates that we will need to double the amount of installed hydropower capacity—which stands today at around 1360 gigawatts worldwide—in order to limit the rise in average global temperatures to 1.5 degrees Celsius above pre-industrial levels.

Meeting the immense impacts of climate change will require strong “top-down” policies to reduce emissions and remove carbon from the atmosphere, as well as building resilience in the face of climate stresses and shocks. As communities and governments undertake rapid and fundamental transformation of sectors and systems—energy, transportation, buildings and even green spaces—the need for governments to develop strategies that drive innovation and technological solutions becomes more urgent and essential.

Supply chain considerations in today’s globalized economy have expanded beyond minimizing costs. As Duncan Wood, Vice President for Strategy and New Initiatives and Senior Advisor to the Mexico Institute at the Wilson Center, noted at a recent panel hosted by the Environmental Change & Security Program as part of the Transatlantic Climate Bridge conference, issues ranging from environmental, social, and corporate governance (ESG) to national security and geopolitics, have transformed critical mineral supply chains into something that is now “inherently political.”

From climate change to COVID-19 and the war in Ukraine, the world is a landscape of increasing instability. Book-ending the Top 5 posts of June are two articles that explore different aspects of these converging risks. In the top post for June, Steven Gale and Mat Burrows write that globally, younger generations are becoming increasingly disengaged and discontent with their democratic governments, civil society, and institutions. Youth disillusionment is not a result of ignorance to current affairs, but rather a lack of faith in democratic institutions to address today’s most pressing global issues. Tackling youth disillusionment, suggest Gale and Burrows, begins with examining youth engagement trends and placing it at the top of the agenda.

In April 2021, the Biden administration announced a new greenhouse gas emissions reduction target for the United States. In the accompanying “nationally determined contribution” submitted to the United Nations Framework Convention on Climate Change, the administration highlighted the interplay between national and subnational policy in driving climate progress. The document promised that federal action will “[build] upon and [benefit] from a long history of leadership on climate ambition and innovation from state, local, and tribal governments.”

Is a “green resource curse” on its way? Kimberly Thompson, a Senior Advisor for Natural Resources and Conflict and the Industry Lead for Mining at the U.S. Agency for International Development (USAID), says that the current status quo in the green mining industry risks “inadvertently creating the conditions” for it to happen.

Few people can name from memory the materials required for wind turbines, photovoltaic panel semiconductors, and electric car batteries. The list is too long, but among the more recognizable minerals used in renewable production are aluminum, lithium, cobalt, iron, copper, lead, and nickel.

Last week saw the launch of SIPRI’s major policy report Environment of Peace: Security in a New Era of Risk, looking at how to manage the growing risks emerging at the nexus of environmental degradation, peace and security.
