Environment & Climate Change

For many, integrating “decarbonization” into public policy, corporate and financial strategies has become a requirement, not an option — yet, what happens when the critical link between climate stability and decarbonization breaks?

At one point in human history, water’s importance in war went beyond bearing convoys, hiding submarines, and slaking soldiers’ thirst. Water was often itself a weapon. In areas where it was scarce, armies took action to make it scarcer to force besieged enemy cities to capitulate, and in areas where it was abundant, combatants destroyed dams and watched the resulting floods carry their adversaries away. Today, however, most combatants recoil at the use of water as a weapon, and only the most depraved deploy it.

Since the end of World War II, nation-states in international conflict have made concerted efforts to restrain the weaponization of water. Distinct from realist and rationalist explanations, the historical record reveals the rise of an international normative inhibition—a “water taboo”—on using water as a weapon.

The nine issue papers contained in this report were proposed and written by graduate students at the Belfer Center for Science and International Affairs at Harvard Kennedy School. They present fact-based, nonpartisan analysis to help focus the next Administration on the key policy debates that must be resolved. And, they aim to create a platform for our students to engage with the most pressing policy issues of the day as they continue their careers in public service.

Today’s economic crisis leaves us with an unsettling and perplexing regret. Why weren’t financial portfolios already adjusted for risks that stem from health events such as pandemics? After all, financial portfolios are adjusted for liquidity risks, market risks, credit risks, and even operational and political risks.

To accelerate the global transition to a low-carbon economy, all energy systems and sectors must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, renewable hydrogen is drawing increased attention today as a versatile and sustainable energy carrier with the potential to play an important piece in the carbon-free energy puzzle. Countries around the world are piloting new projects and policies, yet adopting hydrogen at scale will require innovating along the value chains; scaling technologies while significantly reducing costs; deploying enabling infrastructure; and defining appropriate national and international policies and market structures.

What are the general principles of how renewable hydrogen may reshape the structure of global energy markets? What are the likely geopolitical consequences such changes would cause? A deeper understanding of these nascent dynamics will allow policy makers and corporate investors to better navigate the challenges and maximize the opportunities that decarbonization will bring, without falling into the inefficient behaviors of the past.

For decades, Singapore has been a premier refinery hub and gatekeeper between Asia and the Middle East, but its position is increasingly threatened as producer countries are shifting into the downstream activities that helped make Singapore the “Houston of Asia”. Oil and petrochemicals drive about one quarter of Singapore’s net exports. Greater competition in the global oil and gas value chain could take a heavy toll on the city-state’s national budget and economic growth prospects.
