Environment & Climate Change

Dramatic growth in nuclear energy would be required for nuclear power to provide a significant part of the carbon-free energy the world is likely to need in the 21st century, or a major part in meeting other energy challenges. This would require increased support from governments, utilities, and publics around the world. Achieving that support is likely to require improved economics and major progress toward resolving issues of nuclear safety, proliferation-resistance, and nuclear waste management. This is likely to require both research, development, and demonstration (RD&D) of improved technologies and new policy approaches.

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.

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.

Policies facilitating innovation and large-scale adoption of low-carbon technologies will need to play a central role in global efforts to address climate change, alongside policies targeted directly at reducing emissions.  This paper considers opportunities for improved and expanded international technology development and transfer strategies within the broader context of international agreements and institutions for climate, energy, trade, development, and intellectual property.
