The OECD designs international standards and guidelines for development co-operation, based on best practices, and monitors their implementation by its members. It works closely with member and partner countries, and other stakeholders (such as the United Nations and other multilateral entities) to help them implement their development commitments. It also invites developing country governments to take an active part in policy dialogue.

Under its mandate to track and promote financing for sustainable development from various public and private sources, the OECD undertakes data collection and reporting, analyses flows and policies, and establishes statistical measurement frameworks. On that basis, the Organisation engages with governments and private actors, and recommends more efficient and sound approaches.

The OECD analyses fast-changing global and regional development trends, to help countries of all income levels design innovative policies that meet their needs and improve their populations’ lives.

The OECD works to help middle- and low-income countries strengthen their governance mechanisms, to improve the delivery of public services, meet their development goals and achieve the overall aim of poverty reduction. The OECD also promotes policies focused on preventing the outbreak of conflict and sustaining local and regional peace tracks.

Human well-being, freedom, and dignity are at the heart of development. The OECD helps advance inclusivity, tackle inequality, and eradicate poverty in low- and middle-income countries by promoting policies that ensure people’s basic needs are met and no one is left behind. This includes efforts to increase access to decent, formal work; fight hunger and malnutrition; extend social protection; and achieve gender equality.

Achieving the twin green and digital transitions will require an abundant and regular supply of critical minerals. The technologies enabling renewable power, electric vehicles, consumer electronics require access to critical minerals. Embracing a standards-based approach to mining should ensure favourable development outcomes through responsible and sustainable mining and enable the formation of resilient critical mineral supply chains.

Official development assistance (ODA) is government aid that promotes and specifically targets the economic development and welfare of developing countries. ODA has been the main source of financing for development aid since it was adopted by the OECD’s Development Assistance Committee (DAC) as the “gold standard” of foreign aid in 1969. The OECD is the only official source of reliable, comparable, and complete statistics on ODA.

The 2030 Agenda for Sustainable Development sets out 17 Sustainable Development Goals, with concrete targets like ending child marriage everywhere, or ensuring everyone has access to affordable and reliable electricity. These goals are universal, meaning that all countries have committed to strive towards them. They aim to improve people’s lives all over the world, foster prosperity and protect the planet. To support this global endeavor, the OECD helps countries devise strategies, strengthen governance frameworks and measure progress towards achieving the Goals.

Effective taxation is vital for development. An effective tax system not only raises revenues needed for funding public services, but can also support development goals, for example by helping combat illicit financial flows, reducing inequality through redistribution and addressing health and environmental objectives by influencing taxpayer behaviour.

Fast-growing cities are transforming the economic, social and political landscapes. This is especially evident in Africa where urbanisation offer significant opportunities to accelerate progress towards the 2030 and 2063 development agendas. The OECD provides vital data and policy analysis to assist decision makers in comprehending the impacts of urban growth.
