🌍 Sustainable Development Goals (SDGs)

What are the SDGs?: The Sustainable Development Goals (SDGs) are 17 global goals created by the United Nations in 2015 to solve major problems facing the world by 2030.
  • They aim to reduce poverty and inequality
  • They protect the environment and climate
  • They support peace, justice, and prosperity
  • They apply to all countries, not just poorer ones

🧩 How the SDGs fit together

The SDGs can be grouped using the nested dependencies model.

  • Environment → supports everything else (planet first)
  • Society → depends on a healthy environment
  • Economy → depends on both society and the environment
If the environment fails, society and the economy cannot survive.

🎯 SDGs, targets, and indicators

Each SDG is broken down into targets, and each target is measured using indicators.

  • Goal → the big aim (e.g. clean energy for all)
  • Target → a specific objective within the goal
  • Indicator → data used to measure progress
In exams, indicators are how we know if a target is being achieved.

⚡ Example: SDG 7 – Affordable and Clean Energy

  • Goal: affordable, reliable, and clean energy for everyone
  • Target example: universal access to modern energy
  • Indicator example: percentage of people with access to electricity
  • Another indicator: share of renewable energy in total energy use

📉 Global progress on the SDGs

Progress towards the SDGs has been uneven and slower than expected.

  • Only a small proportion of targets are on track
  • Over half of targets are off track
  • Some targets have stopped improving or worsened

Global events such as pandemics, conflicts, and climate disasters have slowed progress.


🌍 Income and SDG progress

  • High-income countries tend to make faster progress
  • Low-income countries face bigger challenges
  • Progress depends on access to funding, technology, and support
Countries that contributed least to global problems often face the greatest barriers to achieving the SDGs.

⚖️ SDGs and global fairness

Achieving the SDGs is also an issue of environmental and social justice.

  • Wealthier countries are expected to provide funding and technology
  • Support helps poorer countries meet basic needs sustainably
  • Global cooperation is essential for success
The SDGs cannot be achieved by countries acting alone — cooperation matters.

🌍 Uses and Limitations of the Sustainable Development Goals (SDGs)

Big idea: The SDGs are a global framework that helps guide sustainable development, but like all models, they have strengths and weaknesses.

✅ Why the SDGs are useful

  • Common language: governments, businesses, and organisations can use the same goals, targets, and indicators
  • Universal: the SDGs apply to all countries, rich and poor
  • Ambitious vision: for the first time, countries agreed on shared social and environmental goals for the planet
  • Data-driven: many SDGs use measurable indicators to track progress over time
The SDGs help coordinate global action and make progress easier to compare.

⚠️ Limitations of the SDGs

  • Silos: goals are sometimes treated separately instead of as connected systems
  • Lack of context: the same goals may not reflect local challenges faced by different countries
  • Not ambitious enough: some critics argue the SDGs do not challenge harmful economic systems
  • Data gaps: some targets lack good indicators, so progress is hard to measure
If something is not measured well, it is harder to improve.

📝 Exam-ready thinking

  • SDGs provide a shared global framework
  • They support monitoring through indicators and data
  • However, they may oversimplify complex local realities
  • They do not always reflect a full systems approach
In exam answers, always balance uses with limitations when evaluating the SDGs.
