The authors examine the complexities of designing policies that can keep Earth within the biophysical limits favorable to human life.

The authors describe a process for capturing CO2 from the atmosphere in an industrial plant. The design captures ∼1 Mt-CO2/year in a continuous process using an aqueous KOH sorbent coupled to a calcium caustic recovery loop. They describe the design rationale, summarize performance of the major unit operations, and provide a capital cost breakdown developed with an independent consulting engineering firm. They report results from a pilot plant that provides data on performance of the major unit operations.

Decision-makers often seek to design policies that support sustainable development. Prospective evaluations of how effectively such policies are likely to meet sustainability goals have nonetheless remained relatively challenging. Evaluating policies against sustainability goals can be facilitated through the inclusive wealth framework, which characterizes development in terms of the value to society of its underlying capital assets, and defines development to be potentially sustainable if that value does not decline over time.

For more than a decade there has been talk of a global “nuclear renaissance,” and until recently Vietnam looked to be part of it, making plans to build nuclear infrastructure and taking the necessary steps to become a member of the international nuclear community. Then, last month, after a year or more of troubling signs, the government officially suspended its nuclear development plans.

New technology brings great benefits, but it can also create new and significant risks. When evaluating those risks in policymaking, there is a tendency to focus on social acceptance. By solely focusing on social acceptance, important ethical aspects of technological risk could be overlooked, particularly when evaluating technologies with transnational and intergenerational risks. The author examines the case of multinational nuclear waste repositories.
