The 17 Sustainable Development Goals (SDGs): Meaning, Challenges, Solutions & Success Stories

The 17 Sustainable Development Goals (SDGs) were launched by all 193 Member States of the United Nations when the UN General Assembly adopted the resolution “Transforming our World: the 2030 Agenda for Sustainable Development” on 25 September 2015 at the UN Sustainable Development Summit in New York.

The agenda was stewarded by UN Secretary-General Ban Ki-moon and grew out of a multi-year, global consultation that involved governments, civil-society groups, scientists and millions of citizens.

The resolution distils the world’s most urgent social, economic and environmental priorities into 17 global sustainability development goals (SDGs) and 169 targets. They provide a shared framework for governments, businesses, NGOs and citizens to:

  • Eradicate extreme poverty and hunger
  • Protect the planet’s climate, oceans and forests
  • Promote peace, justice and strong institutions
  • Foster inclusive, sustainable economic growth

Unlike previous development frameworks, the Sustainable Development Goals break down complex, interlocking challenges – climate change, inequality, health crises, and more – into clear, measurable targets that governments, businesses, NGOs, and citizens can rally behind. Each goal comes with a set of indicators that allow us to track progress in real time, focus investments where they matter most, and hold decision-makers accountable.

This article gives you a practical, roadmap to all 17 Sustainable Development Goals including a concise yet comprehensive overview of each of the SDGs. For every SDG we provide:

  • A real-world example of the SDG in action
  • Key problems hindering progress
  • Actionable solutions that work in multiple contexts
  • Positive outcomes the world can expect when the SDG is achieved

Also included is a compact reference guide to all 169 official targets that sit beneath the 17 United Nations Sustainable Development Goals (SDGs).

What are The 17 Sustainable Development Goals (SDGs)

Goal 1 – No Poverty: End Poverty in All Its Forms Everywhere

Ending poverty in all its forms is the foundation for sustainable development. Goal 1 focuses on guaranteeing that every person has the resources, opportunities, and resilience to meet basic human needs and withstand economic or climate-related shocks.
