In 1943, as part of the Manhattan Project, the Hanford Nuclear Reservation was established with the mission to produce plutonium for nuclear weapons. During 45 years of operations, the Hanford Site produced about 67 metric tonnes of plutoniumâ€"approximately two-thirds of the nation's stockpile. Production processes generated radioactive and other hazardous wastes and resulted in airborne, surface, subsurface, and groundwater contamination. Presently, 177 underground tanks contain collectively about 210 million liters (about 56 million gallons) of waste. The chemically complex and diverse waste is difficult to manage and dispose of safely. Section 3134 of the National Defense Authorization Act for Fiscal Year 2017 calls for a Federally Funded Research and Development Center (FFRDC) to conduct an analysis of approaches for treating the portion of low-activity waste at the Hanford Nuclear Reservation intended for supplemental treatment. The third of four, this report provides an overall assessment of the FFRDC team's final draft report, dated April 5, 2019.

The second of four, this report reviews the results of the assessments, including the formulation and presentation of conclusions and the characterization and treatment of uncertainties.

The synthesis report is based on the assessment carried out by the three working groups of the IPCC. It provides an integrated view of climate change as the final part of the IPCC's Fourth Assessment Report.

Global change assessments inform decision makers about the scientific underpinnings of a range of environmental issues, such as climate change, stratospheric ozone depletion, and loss of biodiversity. Dozens of assessments have been conducted to date by various U.S. and international groups, many of them influencing public policies, technology development, and research directions. This report analyzes strengths and weaknesses of eight past assessments to inform future efforts. Common elements of effective assessments include strong leadership, extensive engagement with interested and affected parties, a transparent science-policy interface, and well defined communication strategies. The report identifies 11 essential elements of effective assessments and recommends that future assessments include decision support tools that make use of information at the regional and local level where decisions are made.

The Economics of Ecosystems and Biodiversity (TEEB) study is a major international initiative drawing attention to local, national and global economic benefits of biodiversity, to highlight the growing costs of biodiversity loss and ecosystem degradation, the benefits of investing in natural capital, and to draw together expertise from the fields of science, economics and policy to enable practical actions. Drawing on a team of more than one hundred authors and reviewers, this book demonstrates the value of ecosystems and biodiversity to the economy, society and individuals. It underlines the urgency of strategic policy making and action at national and international levels, and presents a rich evidence base of policies and instruments in use around the world and a wide range of innovative solutions. It highlights the need for new public policy to reflect the appreciation that public goods and social benefits are often overlooked and that we need a transition to decision making which integrates the many values of nature across policy sectors. It explores the range of instruments to reward those offering ecosystem service benefits, such as water provision and climate regulation. It looks at fiscal and regulatory instruments to reduce the incentives of those running down our natural capital, and at reforming subsidies such that they respond to current and future priorities. The authors also consider two major areas of investment in natural capital - protected areas and investment in restoration. Overall the book underlines the needs and ways to transform our approach to natural capital, and demonstrates how we can practically take into account the value of ecosystems and biodiversity in policy decisions - at national and international levels - to promote the protection of our environment and contribute to a sustainable economy and to the wellbeing of societies.
