Environment & Climate Change

This brief looks at the so-far inadequate responses of the Chinese government and makes the case that new institutions are needed to allow China to meet this growing challenge.

Industrial and urban water reuse should be considered along with desalination as options for water supply in Saudi Arabia. Although the Saudi Ministry for Water and Electricity (MoWE) has estimated that an investment of $53 billion will be required for water desalination projects over the next 15 years [1], the evolving necessity to conserve fossil resources and mitigate GHG emissions requires Saudi policy makers to weigh in much more heavily the energy and environmental costs of desalination. Increasing water tariffs for groundwater and desalinated water to more adequately represent the costs of water supply could encourage conservation, but also reuse, which may be more appropriate for many inland and high-altitude cities.

African agriculture is at a crossroads. Persistent food shortages are now being compounded by new threats arising from climate change. But Africa also has three major opportunities that can help transform its agriculture to be a force for economic growth. First, advances in science, technology, and engineering worldwide offer Africa new tools needed to promote sustainable agriculture. Second, efforts to create regional markets will provide new incentives for agricultural production and trade. Third, a new generation of African leaders is helping the continent focus on long-term economic transformation.

An effective international climate agreement poses formidable challenges. Existing agreements, naturally, have some good features. Further improvements are being discussed in the current negotiations. But the cost and uncertainty associated with regular renegotiation of commitments is not being addressed. The São Paulo Proposal suggests mechanisms that would avoid the need for regular renegotiation of commitments and suggests other ways to make international climate agreements more effective.

This policy brief outlines urgent priorities for U.S. energy policy at the dawn of the Obama administration, and recommends specific steps that the U.S. government should take to address the numerous energy-related challenges facing the United States. It is based on the book, Acting in Time on Energy Policy (Brookings 2009), edited by Kelly Sims Gallagher, director of the Energy Technology Innovation Policy research group at the Harvard Kennedy School's Belfer Center.

We concentrate on six topics: climate change policy, carbon capture and storage policy, oil security policy, energy-technology innovation policy, electricity market structure, and infrastructure policy. The United States cannot afford to wait any longer to enact long-term policies on these topics. In fact, acting early is clearly in the longer-term interest of the United States.

The Kyoto Protocol uses a top-down mechanism to negotiate economy-wide emissions caps. This paper proposes an alternative "sectoral" approach, which would determine industry-level emissions reduction targets based on technological analyses.
