What are the root causes of gender inequality? Building on the fifth edition of the Social Institutions and Gender Index (SIGI), the SIGI 2023 Global Report provides a global outlook of discriminatory social institutions, the fundamental causes of gender inequality. It reveals how formal and informal laws, social norms and practices limit women’s and girls’ rights and opportunities in all aspects of their lives. Globally, 40% of them continue to live in countries where gender-based discrimination is assessed as high or very high. The report stresses how discriminatory social institutions curtail women’s and adolescents’ fundamental access to sexual and reproductive health and rights. It also sheds light on the gendered impacts of climate change and underlines how women can play a pivotal role in climate change mitigation and adaptation. To accelerate efforts aimed at achieving SDG 5 and eliminating the underlying and structural factors that hamper women’s empowerment, the report offers concrete policy actions. It calls for a gender-transformative approach to leverage crises and challenges into windows of opportunity to establish women and men as agents of change.

By 2050, the global population living in cities is projected to reach 5 billion, growing from 3.5 billion in 2015. Massive investment in infrastructure will be needed to accommodate this growth, and to adapt infrastructure to climate change and benefit from the digital transition. This report explores three ways to meet this challenge. Firstly, it outlines how new forms of urban planning can help to mobilise private finance for inclusive, resilient and sustainable urban investment. Secondly, it explores how leveraging private investment can help to strengthen cities capacity to support needed investment in a tighter fiscal environment. Finally, it considers the potential opportunities and challenges for mobilising sustainable finance – green, social and sustainable bonds and loans, sustainability-linked bonds and catastrophe bonds – for infrastructure investment by City Governments. The report also includes 17 short case studies from 12 countries that demonstrate innovative practices for creating the Cities of Tomorrow.

This report is the third focused assessment of tax and development issues produced for G20 Finance Ministers and Central Bank Governors. It takes stock of progress by developing countries in the context of their engagement with the OECD/G20 Inclusive Framework, an international collaboration of over 140 countries and jurisdictions working together to tackle tax avoidance, improve the coherence of international tax rules and ensure a more transparent tax environment. Building on the 2022 Roadmap on Developing Countries and International Tax, the report refines and focuses on the range of actions to be undertaken in support of developing countries’ key international tax priorities, including, in particular, the internationally agreed standards on Country-by-Country reporting and the Global Anti-Base Erosion (GloBE) Rules which will put in place a global minimum tax for large multinational enterprises.

Africa’s Development Dynamics uses lessons from Central, East, North, Southern and West Africa to develop policy recommendations and share good practices across the continent. Drawing on the most recent statistics, the analysis of development dynamics aims to assist African leaders in reaching the targets of the African Union’s Agenda 2063 at all levels: continental, regional, national and local. This edition explores how Africa can attract investments that offer the best balance between economic, social and environmental objectives. Its fresh data and analysis aim to help policy makers improve risk assessments, strengthen African-led partnerships, and accelerate regional integration in ways that increase sustainable investments. Two continental chapters examine Africa’s investment landscape and related policy priorities. Five regional chapters offer tailored recommendations in strategic areas including natural ecosystems, renewable energy, climate finance and agri-food value chains. Africa’s Development Dynamics feeds into a policy debate between the African Union’s governments, citizens, entrepreneurs and researchers. It proposes a new collaboration between countries and regions, focusing on mutual learning and the preservation of common goods. This report results from a partnership between the African Union Commission and the OECD Development Centre.

Located in the mid-Atlantic, the archipelagos of the Azores is an autonomous region of Portugal and an European Union Outermost Region. Once central to global trade routes, the Azores are aspiring to regain a prominent international role by leveraging their unique geographical, natural and historical attributes. To that end, this Production Transformation Policy Review (PTPR) Spotlight identifies priority actions in several areas, including scientific research and collaborations, the ocean economy, agro-food and renewable-energy value chains. It shows the importance for EU Outermost Regions, as well as for Small Island Developing States (SIDS), of building resilient international ties. It benefited from an extensive peer review process involving public and private stakeholders from Brazil, Iceland and the United States.

This Glossary defines concepts and terms commonly used in evaluation and results-based management. It provides a shared understanding to support the design, management, monitoring and evaluation of interventions for sustainable development. As a reference document, it is helpful for those commissioning, managing, or conducting evaluations, as well as people involved in strategy or programme development, management and implementation. While originally developed for international development co-operation, the Glossary can be applied in any field of public policy and is also useful for civil society, academia, and other non-state actors. This second edition includes updated content, including new definitions for the widely used evaluation criteria – relevance, coherence, effectiveness, efficiency, impact and sustainability – endorsed by the OECD Development Assistance Committee in 2019. It also provides minor updates to the original text to reflect current good practice. As concepts and language are constantly evolving, the document will be revisited and updated in due course. This publication also includes a Spanish translation 'Glosario de términos clave en evaluación y gestión basada en resultados para el desarrollo durable (Segunda edición)'.

The rapid advances of artificial intelligence (AI) in recent years have led to numerous creative applications in science. Accelerating the productivity of science could be the most economically and socially valuable of all the uses of AI. Utilising AI to accelerate scientific productivity will support the ability of OECD countries to grow, innovate and meet global challenges, from climate change to new contagions. This publication is aimed at a broad readership, including policy makers, the public, and stakeholders in all areas of science. It is written in non-technical language and gathers the perspectives of prominent researchers and practitioners. The book examines various topics, including the current, emerging, and potential future uses of AI in science, where progress is needed to better serve scientific advancements, and changes in scientific productivity. Additionally, it explores measures to expedite the integration of AI into research in developing countries. A distinctive contribution is the book’s examination of policies for AI in science. Policy makers and actors across research systems can do much to deepen AI’s use in science, magnifying its positive effects, while adapting to the fast-changing implications of AI for research governance.

The OECD’s Development Co-operation Profiles compile and analyse verified statistics and trends on how development assistance is allocated geographically, to sectors, multilateral and civil society organisations, cross-cutting priorities such as gender equality and women’s economic empowerment and the environment and climate, and to mobilise private finance. The profiles cover official and philanthropic providers of aid, official development assistance (ODA) and development finance. These providers include members of the OECD and its Development Assistance Committee (DAC), other countries and philanthropic foundations. The profiles also give an overview of key strategic and policy priorities for development co-operation, the institutional set-up and evaluation systems. The Development Co-operation Profiles are published annually and are a pillar of the OECD’s Development Co-operation Report . For more than 50 years, the Development Co-operation Report has brought new evidence, analysis and ideas to the Development Assistance Committee (DAC) and international community more broadly, shaping policy reform, behaviour change and promoting best practices in development co-operation. Each year the report analyses a fresh policy issue that is timely, relevant or challenging for development co-operation policy and finance. The main report also includes shorter profiles of each provider that present key trends through infographics.

The United States, the world’s largest economy, has made progress in reducing several environmental pressures while maintaining one of the highest Gross Domestic Products per capita in the world. It has decoupled emissions of greenhouse gases, air pollutants, water abstractions and domestic material consumption from economic and population growth. However, high consumption levels, intensive agricultural practices, climate change and urban sprawl continue to put pressure on the natural environment. Despite the recent acceleration of action to address climate change, further efforts are needed to achieve the goal of net-zero greenhouse gas emissions by 2050. The United States is also among the major contributors to marine litter with serious consequences for communities and the environment. The review provides 30 recommendations to help the United States improve its environmental performance, with a special focus on marine litter and a cross-cutting focus on environmental justice. This is the third Environmental Performance Review of the United States. It provides an independent, evidence-based evaluation of the country’s environmental performance over the past decade.
