This report, published by SDSN partner Evolved Energy and DDPP Director Jim Williams, inaugurates a series of annual updates that aim to move pathways analysis in the U.S. beyond isolated proofs-of-concept towards becoming a practical implementation tool for addressing next-stage challenges in energy and climate change mitigation. These are detailed technical blueprints for the transition to a net-zero economy, including the production and use of energy, the land carbon sink, and non-energy greenhouse gas emissions. We used sophisticated, fine-scaled software modeling to map the infrastructure changes, technologies, and costs required to reach carbon neutrality by mid-century along various alternative pathways, while maintaining U.S. economic productivity and a reliable energy system. A growing list of long-term pathways studies in the last few years indicates increasing interest in this type of work. However, a lack of transparency and standardization across these studies renders comparison of results, methods, data sources, and input assumptions difficult. Pathways studies to date are largely a set of one-off snapshots of possible futures, with relatively little coordination between research efforts or continuity over time. The objectives of this project, supported by Breakthrough Energy, are similar in some ways to those of the U.S. Department of Energy’s Annual Energy Outlook (AEO): providing an annually refreshed objective benchmark for use by a wide variety of audiences. The AEO is an indispensable tool, but where the AEO’s focus is a long-term forecast of business as usual, our analysis is focused specifically on pathways to deep decarbonization to enable better decision making by policy makers, better informed advocacy, and more clarity for the business community. In the wake of the newly passed Inflation Reduction Act, which our initial modeling estimates will decrease U.S. greenhouse gas emissions by 40% by 2030, this study charts a course to their complete elimination by mid-century. It analyzes multiple pathways to net-zero and how it can be reached given many potential twists and turns along the way, such as the rise and fall of oil prices, technology breakthroughs or stagnation, and public preferences. The timeline below shows key milestones in a Central scenario that maintains an ambition to reduce emissions by 50%-52% from 2005 levels by 2030 and achieves net-zero emissions by 2050.

Le Bénin est le premier pays africain à bénéficier d'une analyse détaillée de la part du Réseau de Solution pour le Développement Durable (SDSN). Parmi les pays à revenu intermédiaire de la tranche inférieure, le Bénin est l’un des seuls avec un fort engagement pour les Objectifs de Développement Durable (ODD).

The Sustainable Development Report (SDR), including the SDG Index and Dashboards tracks progress on the Sustainable Development Goals (SDGs). The report shows that multiple and simultaneous international crises have halted progress on the universal goals adopted by all UN member countries during the historic 2015 summit.

The Sustainable Development Solutions Network (SDSN) was set up in 2012 under the auspices of the UN Secretary-General. SDSN mobilizes global scientific and technological expertise to promote practical solutions for sustainable development, including the implementation of the Sustainable Development Goals (SDGs) and the Paris Climate Agreement. SDSN works closely with United Nations agencies, multilateral financing institutions, the private sector, and civil society. This overview summarizes the major projects, programs, and initiatives SDSN is undertaking in 2022, including the work of the national and regional networks, SDSN Youth, the FABLE and FELD initiatives, the SDG Index and Dashboards, the World Happiness Report, TReNDS, and the SDG Academy.

The Center for Global Commons, Together with the Potsdam Institute for Climate Impact Research, The Sustainable Development Solutions Network and SYSTEMIQ, sets out an actionable, Science-based framework for global Commons stewardship

The COVID-19 pandemic has shown us that the world is capable of acting with urgency to tackle crises on a global scale. It has demonstrated that the focused and coordinated efforts of global experts can lead to rapid and radical changes to address an emerging threat – for example in global mobility, ways of working, and medical advances. It also highlighted the crucial importance of tackling misinformation, demonstrated that individual behaviors can benefit society collectively, and shown how structural inequalities predetermine who is most affected and how - all issues that have clear parallels to the climate crisis. This white paper explores the development of strategies through an interdisciplinary approach to motivate behaviour change, tackle misinformation and address inequality in times of crises.

Wide-ranging EU policy initiatives of 2020-2021 are tangible examples of the willingness of EU leaders to adopt SDGs as Europe's economic development framework. The substantial alignment of the European Green Deal with SDGs is a clear finding of our report’s analysis. However, even this ambitious framework may fall short of the necessary action to tackle major sustainability challenges. Moreover, since the inancing needs are huge, sustainable finance aspects will be the main topic of further work of this Senior Working Group in the coming years.
