The contribution of energy efficiency enhancement measures could be significant in the realisation of which of the following Sustainable Development Goals (SDGs)?

Energy efficiency measures most strongly advance the goals on clean energy, cities, consumption and climate.

These are Sustainable Development Goals seven, eleven, twelve and thirteen.

Adding goals fourteen and fifteen brings in oceans and land, which efficiency touches only weakly.

Adding goals five and seventeen brings in gender and partnerships, less directly linked to efficiency.

Goal seven seeks affordable clean energy that efficiency directly supports.

Goal thirteen on climate action gains as saved energy cuts emissions.
