Sustainable Development Goal 6

Billions of people are still living without safely managed water and sanitation. Sustainable Development Goal (SDG) 6 is to ensure the availability and sustainable management of water and sanitation for all by 2030. Achieving SDG 6 is integral to the success of the 2030 Agenda for Sustainable Development, which aims to end extreme poverty and protect the planet.

Communications should be a two-way exchange. ‘Questions people ask’ is a new feature where we answer some of the questions we get asked about important issues, such as, climate changewater scarcity and wastewater. Through responding to queries from our audiences, we aim to explain key issues in a clear and engaging way that fosters ongoing conversations.

The UN-Water SDG 6 Data Portal brings all the United Nations’ water and sanitation information into one place. Designed for decision-makers, advisors, technical professionals, researchers and students, there are tools to help visualize and analyse the information, creating a clear picture of how the world is progressing towards the various SDG 6 targets.

Monitoring progress towards SDG 6 helps policy- and decision makers identify challenges and opportunities, set priorities, communicate progress, and generate support and investment. SDG 6 Progress Reports are primarily based on national official data sources, compiled and validated by United Nations custodian agencies.

What can you do to help solve the water and sanitation crisis? In 2023, the UN is uniting the world around accelerating progress towards SDG 6. UN-Water is coordinating a global campaign asking people and organizations to ‘Be the change’ they want to see in the world. Choose from a list of #WaterActions and play your part.
