Analyzing Foreign and Domestic Policy to Determine a Pathway to Achieving the US' NDC with a Focus on Advanced Reactors and Hydrogen

The United states in 2021 released a nationally determined contribution indicating goals to reach 50-52% reduction in CO2 emissions by 2030 compared with 2005 and to achieve zero carbon electricity by 2035. Current policy does not put us on course to achieve these goals, so we investigated policies that could form a pathway to achieve these goals in the US. We focused on the use of advanced nuclear reactors and hydrogen, but analyzed all relevant sectors to achieve our goals. This report also focuses on analyzing existing foreign policies and determining the most effective policies in each sectors. By combining the most effective policies from around the world in each sector, we find that we can set policies that form a pathway that is ambitious enough to meet the NDC goals.

The Joint Convention, Its Global Impact and U.S Continuing Involvement - 16645

The Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management (hereafter called the Joint Convention) is an international convention, conducted under the auspices of the International Atomic Energy Agency (IAEA). It is one of a suite of international instruments dealing with nuclear safety and physical security, which serve to promote a global culture for the safe use of radioactive materials. Unlike other safety or security conventions, however, the Joint Convention deals exclusively with the end of the nuclear fuel cycle. The Joint Convention focuses on the lessons to be learned from past experience and existing facility operations, which can be implemented in the policies and designs for future operating facilities in the nuclear fuel cycle. The U.S. has participated fully in the review process, as well as setting forth initiatives to sponsor increased ratification. The U.S. holds the current Joint Convention presidency for the Fifth Review Cycle. Because of the important benefits associated with active participation, the U.S. has strongly supported a Regional Conference Initiative outreach program to increase membership. We also provided an expert for each of the conferences to assist in advancing the message to non-Member States, in particular developing nations considering ratification. The Joint Convention process also provides opportunities to identify future areas of bilateral and multilateral technical and regulatory cooperation with other Parties. Furthermore, the Joint Convention is consistent with U.S. foreign policy considerations to support, as a priority, the strengthening of the worldwide safety culture in the use of nuclear energy.

Looking up, down, and sideways: Reconceiving cumulative effects assessment as a mindset

Despite all the effort that has gone into defining, researching and establishing best practices for cumulative effects assessment (CEA), understanding remains weak and practice wanting. At one extreme of implementation, CEA can be described as merely an irritant to the completion of a project-specific environmental assessment (EA). At the other extreme, the conceptual view is that all effects in EA should be deemed cumulative unless demonstrated otherwise. Our purpose here is to consider how we might reconceive CEA as a mindset that is at the heart of absolutely every assessment of valued ecosystem component (VEC) to ensure that we understand the relative contributions of various stressors and can decide when cumulative effects may foreclose future activities due to impacts on VECs. Conceptually, we ground the CEA mindset in the context of three lenses that must all be functioning and working together for the mindset to be operative: a technical lens; a law and policy lens; and a participatory lens. Our arguments are based on a review of the CEA, strategic effects assessment (SEA) and regional effects assessment literatures, an examination and consideration of Canadian EA and SEA case practice, and our combined professional experiences. Through using the Bay of Fundy in Canada as a case example, we establish the concept of the CEA mindset and an approach for moving forward with implementation. - Highlights: • Conceptualization of cumulative effects assessment as a mindset. • Elaboration of technical, law and policy and participation lenses critical to CEA • Coordination and integration of cumulative effects for valued ecosystem components • Application in Bay of Fundy ecosystem and terrestrial watershed.

Resolving potential energy conflicts among allies: The 2015 United States-Republic of Korea nuclear cooperation agreement

After four years of sometimes contentious negotiations (that at one point required a two-year extension from the U.S. Congress), the United States and Republic of Korea signed a new nuclear cooperation agreement in the summer of 2015. These negotiations caused strain in one of the closest bilateral relationships the U.S. has in Asia – a regional priority for the foreign policy of the Obama administration. This paper examines energy conflict within the confines of an otherwise cooperative and productive partnership. It examines the strategic, technical, economic, and political factors that extended the negotiation period and the creative compromises that led to a final agreement. It then considers the potential pit-falls in implementing the agreement and the implications, in terms of process and substance, for future negotiations regarding civilian nuclear cooperation.

China-Pakistan Economic Corridor.

International trade and related economic activities in Central and South Asia are increasing as developing economies, particularly India and Pakistan, grow. China continues to emerge as a major regional and global power and has embarked upon numerous regional economic and political initiatives . A major development is the China - Pakistan Economic Corridor (CPEC), a host of infrastructure and trade projects worth over 40 billion American dollars . This report analyzes CPEC a nd its potential regional effects, including the trade security implications of the port and land infrastructure developments . As trade increase s in the reg ion and the major CPEC infrastructure projects are completed, there will be numerous implications on trade security and geopolitics within South Asia. CPEC projects uniquely intersect numerous regional situations, including territorial disputes in Kashmir, the Afghanistan/Pakistan border, and Chinese foreign policy a mbitions. A nuanced understanding of these effects can influence future policy adjustments in this region . The views expressed in this report are those of the author and do not necessarily reflect the position of Sandia National Laboratories or the author's current and past institutions.

Report of a Workshop on Nuclear Forces and Nonproliferation Woodrow Wilson International Center for Scholars, Washington, DC November 30, 2017

At a time which some view as the end of the post-Cold War era, geopolitics is increasingly fluid, complex and dangerous, including Russian and Chinese modernization of their nuclear and conventional forces nuclear and their increasingly aggressive foreign policies; North Korean nuclear and missile tests and provocations; Iran’s missile tests, regional ambitions and support for terrorism; Syria’s civil war and use of chemical weapons; and the growing global threat of Islamic terrorism. In this new security environment, potential adversaries are emboldened. Allies are reacting to more concrete and tangible threats. They are demanding greater assurances and, in some cases, questioning the credibility of the guarantees we offer and debating the pursuit of nuclear arms in ways we have not seen since the Treaty on the Nonproliferation of Nuclear Weapons (NPT) was created.

Embassy Science Fellowship (Final Report)

Argentina is home to the highest number of professional scientists per capita in South America. How those human and natural (biodiversity, critical minerals, e.g.) resources are utilized has significant repercussions for the security of the Western Hemisphere and should be of significant interest to US foreign policy. As outlined in the US Secretary of State’s recent (25 Jan, 2025) op-ed, the current administration is seeking to reforge ties with Latin America through “partnership and co-operation” after several decades of varying levels of neglect, a palpable sentiment amongst Argentine scientists and government ministers. This presents an opportunity to provide specific guidance on how coordinated direct policy making, bilateral cooperation, and guided investment in those areas benefits Argentina directly as well as US interests in the hemisphere.

Regional Cooperation to Strengthen Safeguards

President Obama’s decision over four years ago to ”pivot” toward Asia represented an important strategic shift in American foreign policy and a rebalancing of U.S. economic and security engagement in the Asia-Pacific countries. The United States has since supported a variety of regional initiatives aimed at promoting nuclear security and safeguards. When a new regional organization, the Asia-Pacific Safeguards Network (APSN) was established in 2010, DOE/NNSA became an early member and enthusiastic advocate. Launched on the initiative of Australia, Japan, Republic of Korea, and Indonesia, the APSN aims to strengthen the quality and effectiveness of safeguards implementation in the Asia-Pacific region.

The U.S. DOE-EM International Program - 17411

The U.S. Department of Energy (DOE) Office of Environmental Management (EM) has a mission to complete the safe clean-up of the environmental legacy resulting from six decades of weapons production and energy research. This effort is recognized as one of the largest and most diverse and technically complex environmental clean-up operations in the world. The overall strategy to address this challenge includes several components, one of which involves leveraging the expertise within the International community, when applicable. The opportunities related to international collaborations are an important component of the DOE EM strategy for the clean-up mission, providing excellent forums for EM to stay beneficially engaged with the international community and our global partners. EM has been supporting the clean-up mission of the Department through international collaborations for almost 20 years. The EM International Program is sponsored by the DOE EM Office of the Chief of Staff (EM-2.1), which directly supports the DOE-EM Office of Assistant Secretary (EM-1), in coordination with the entire EM organization. The primary objective of the EM International Program is to provide benefit to the Department in successful completion of the EM clean-up mission, through establishing strategic approaches for specific international collaboration initiatives that are focused on appropriate strategic program goals. The EM International Program strategy to support the EM mission includes many facets, but they can generally be grouped into two primary areas. First, the EM International Program maintains, establishes, and/or participates in international agreements such that appropriate mechanisms are available for conducting international collaborations with foreign government organizations, educational institutions and private industry to leverage resources and link international experience and expertise, in support of the EM mission and compliant with US foreign policy. Second, through coordination with the EM Office of Technology Development (EM-3.2), the EM International Program leverages these agreements to identify mutually beneficial opportunities to evaluate, test, and adapt technologies, capabilities, and expertise for application to EM mission needs. These activities directly support goals within the current DOE Strategic Plan 2014 - 2018, issued in April 2014. Working with the Office of Technology Development, the EM International Program is developing a process for identifying and selecting collaborative international technology projects for Fiscal Year 2017 (FY17) that have high potential impact to the EM mission. The technical scope of these activities is expected to span the entire EM mission, including tank waste and nuclear materials management; groundwater and soil remediation; deactivation and decommissioning; and radioactive waste disposal operations. Depending on budget availability, these collaborative activities are expected to be awarded by mid-FY17. (authors)

Global Energy Policy to Achieve the United States’ Nationally Determined Contributions: Potential Pathway

In 2021, the United States declared its Nationally Determined Contribution (NDC) in preparation for the COP26 climate summit, setting goals to achieve zero emission electricity by 2035, and reducing net emissions by 50–52% compared to 2005 levels. The current U.S. energy policies were found to not be adequate to meet these goals, thus it is necessary to draft a pathway to achieving these goals through policy changes. This study focused on foreign energy policies to analyze the most effective policies in a host of sectors. By identifying the most ambitious and effective policies from around the world in each sector, this study was able to suggest a policy pathway that can potentially achieve both of goals set in the NDC. In guiding the development of the proposed policy pathway, this study analyzed policies from Australia, Canada, California, China, Denmark, France, Germany, Japan, Russia, South Korea, Sweden, the United Kingdom, and the United States. This study found that the most drastic CO2 reductions came from low-carbon electricity policy, but contributions were also made from carbon capture, reforestation, hydrogen, energy efficiency, and climate smart agriculture.

Foreign direct investment with tax holidays and policy uncertainty

Abstract We study foreign direct investment agreements that entitle firms to a lower tax rate during a tax holiday period. Our model considers both finite and uncertain tax holiday period settings. We show that the tax holiday duration may have, for small tax rate reductions, a nonmonotonic effect on the investment timing. For sufficiently high tax reductions, a longer tax holiday speeds up investment. A higher tax reduction during the tax holiday and a lower uncertainty are shown to have a monotonic effect on the threshold, hastening investment. However, in case of a finite tax holiday, for exceptional high salvage values, a higher uncertainty can speed up investment. We show the usefulness of our model to design an optimal incentives package that prompts investment.

Multivariate pluvial flood damage models

Depth–damage-functions, relating the monetary flood damage to the depth of the inundation, are commonly used in the case of fluvial floods (floods caused by a river overflowing). We construct four multivariate damage models for pluvial floods (caused by extreme rainfall) by differentiating on the one hand between ground floor floods and basement floods and on the other hand between damage to residential buildings and damage to housing contents. We do not only take into account the effect of flood-depth on damage, but also incorporate the effects of non-hazard indicators (building characteristics, behavioural indicators and socio-economic variables). By using a Tobit-estimation technique on identified victims of pluvial floods in Flanders (Belgium), we take into account the effect of cases of reported zero damage. Our results show that the flood depth is an important predictor of damage, but with a diverging impact between ground floor floods and basement floods. Also non-hazard indicators are important. For example being aware of the risk just before the water enters the building reduces content damage considerably, underlining the importance of warning systems and policy in this case of pluvial floods. - Highlights: • Prediction of damage of pluvial floods using also non-hazard information • We include ‘no damage cases’ using a Tobit model. • The damage of flood depth is stronger for ground floor than for basement floods. • Non-hazard indicators are especially important for content damage. • Potential gain of policies that increase awareness of flood risks.

Determinants of land take at the regional scale: a study concerning Sardinia (Italy)

In its “Roadmap to a Resource Efficient Europe” (Communication COM(2011) 571 of 20 September 2011), the European Commission (EC) established an ambitious goal for the European Union (EU), that of achieving no land take by 2050; towards this aim, a key milestone for the year 2020 was set, by stating that European policies in the programming period 2014–2020 ought to consider both their direct and their indirect impacts on land use in the EU. Within this framework, this paper builds upon the findings of a previous paper (Zoppi and Lai, 2014), in which we estimated the magnitude of land take over a short period of time (2003–2008) in Sardinia, an Italian NUTS2 region, and we assessed whether and how land take is related to a set of variables that are regarded as important determinants in the literature, such as parcel size, accessibility, and proximity to main cities and towns, to the coastline, or to protected areas. In this paper we study the land-taking process taking Sardinia as a case study, in two larger time periods, 1960–1990 and 1990–2008. We assess if, and to what extent, these factors reveal similar, or different, effects in the two periods, and try to identify consistencies concerning the determinants of land take. - Highlights: • Population density and parcel size significantly affect the magnitude of land take. • The presence of nature conservation areas hinders land taking processes. • Extensive urbanization might effectively preserve non-artificial land. • Balanced accessibility of settlements and nature conservation regional policies can effectively contrast land take. • Size of non-artificial land parcels that become artificial is negatively and significantly connected to land take.

Community participation in Health Impact Assessment. A scoping review of the literature

Currently, the engagement of local communities in Health Impact Assessment is becoming more and more important. A scoping review was performed to take stock of visions, methods and experiences in this field. A combined Scopus and Medline search yielded 100 articles in scientific journals. The final selection consisted of 43 papers, including case studies, evaluation studies, reviews, and opinion papers. After analysis, consultation of four experts was performed to check preliminary study outcomes. A grey literature web search was performed to check and complement the results. Results show that community participation is generally considered a core element in HIA. Views as expressed in the papers concern, firstly, the need for and value of local knowledge, secondly, the adherence to or application of democratic values and, thirdly, empowerment of communities. Three categories of methods are used in relation to community participation, often in combination: methods to facilitate knowledge elicitation, to ensure the inclusion of communities in the HIA process, and to build community capacity to participate in policy development. However, the theoretical or practical underpinning of the choice for specific methods is mostly not presented. The experiences described in the papers mainly focus on the access to local knowledge and its usability as a source of evidence in the HIA process. Described effects of community participation are (improved) relations between communities and local agencies, policy makers and professionals and the empowerment of community members. Although these effects are ascribed to community participation, many papers do not provide support for this conclusion beyond the retrospective perception of participants. Expert consultation and additional analysis of the grey literature supported the results derived from the scientific literature and provided more in-depth knowledge. In the grey literature theoretical frameworks, methods and tools for community participation in HIA were more extensively reported as compared to the scientific literature. We conclude that the visions, methods and experiences concerning community participation show that a participative approach may contribute to better, context specific knowledge. It appears that participative HIA has health promotion potential as it helps develop responsive policies. To accomplish this, HIA should, firstly, be better embedded in broader health promotion programmes. Secondly, the methods and approaches for community participation applied in HIA should be theory-informed and well described. The grey literature offers entry points. Finally, more robust and systematic evaluation and research is needed to assess the impact of HIAs on communities and policies.

Analysis of the decision-support function of policy assessment in real-world policy making in the field of poverty and social inequalities. Case study on migrant integration policies in the Brussels-Capital Region

Despite its high potential to support decision-making, the role of policy assessment in real-world policy making in the field of poverty and social inequalities remains largely questioned. In this study, we analyse policy assessment's role in a context of real-world policymaking, by means of a case study on a legislative proposal on integration policy for immigrant newcomers in the Brussels-Capital Region, for which we evaluate the potential effects on poverty and social inequalities. We first analyse the policy process surrounding the policy proposal – a process that is often treated as a black box within policy assessment research. Understanding the factors that influence and determine the decision-making process, enables us to gain insight into the potential decision-support function(s). Second, we develop an approach to policy assessment that aims to fully exploit its potential to contribute to the functions of both instrumental and conceptual learning. For this purpose, we propose to introduce the approach of realist evaluation and to focus on evaluating the underlying policy intervention theory from the perspective of poverty and social inequalities. Finally, we illustrate this new approach and its added value by applying it to the legislative proposal on integration policy and analyse its contribution to policy-oriented learning. - Highlights: •The field of policy assessment should draw on insights from policy studies. •We unpacked the policymaking black-box to identify the mechanisms of policy change. •The policy process is driven by an interaction of ideas, interests and institutions. •Policy assessment's potential lies in both instrumental and conceptual learning. •We propose to integrate realist evaluation's logic of inquiry within policy assessment.

Strengths and Limitations of Governmental Support for Environmental Technology in Japan

In recent years, Japanese government and industry have initiated a wide range of policies, programs, and investment strategies responsive to the growing agenda of domestic and global environmental problems. For the most part, these actions have not been due to any significant domestic envi ronmental political pressure but primarily because of the perception that "green" products and manufacturing methods are simply good business. These strategies have, therefore, been closely linked to export and foreign aid policies of long-term benefit to the Japanese economy. A strength of the Japanese approach to environmental policy is the govern ment's ability to bring together a range of business to create a climate for long-term investment in promising new technologies such as fuel cells and electric vehicles. Because this approach is done to advance industrial policy as much as environmental goals, industrial interests are responding to busi ness opportunities, rather than environmental constraints. The Japanese sys tem is, however, not without its own blind spots and limitations. For exam ple, very little has been done to improve the energy efficiency of consumer products, including automobiles, since the mid 1980s. Japanese industry has so far not demonstrated much awareness of concepts like "design for envi ronment" that imply a fundamental reexamination of manufacturing meth ods and materials. The Japanese response to conservation issues that tend not to have technological solutions or potential for business development has also not been as impressive.
