Environment & Climate Change

This paper is a background review representing part of the initial phase of the Financing the Urban Transition work program. The review builds on a growing body of research that highlights both the importance of national sustainable infrastructure and the need to develop more effective and efficient financing mechanisms for delivering compact, connected cities that meet the UN’s Sustainable Development Goals. While progress has been made in both these areas over the last five years, there remains a policy gap between the international/national level and the municipal level.

Despite substantial progress in improving nuclear security in recent years, there is more to be done.  The threats of nuclear theft and terrorism remain very real.  This paper recommends learning from the much stronger national and international efforts in nuclear safety, and in particular taking steps to build international understanding of the threat; establish effective performance objectives; assure performance; train and certify needed personnel; build security culture and exchange best practices; reduce the number of sites that need to be protected; and strengthen the international framework and continue the dialogue once leaders are no longer meeting regularly at the summit level.

In pursuit of a workable successor to the Kyoto Protocol, this study offers a framework of formulas that produces precise numerical targets for emissions of carbon dioxide (CO2) and other greenhouse gases, in all regions of the world in all decades of this century....Firms, consumers, and researchers base their current decisions to invest in plant and equipment, consumer durables, or new technological possibilities on the expected future price of carbon: If government commitments are not credible from the start, then they will not raise the expected future carbon price.

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.
