Tracking Clean Energy Progress

Assessing the latest information on how 45 critical energy technologies and sectors are contributing to global clean energy transitions

Where do we need to go?

The IEA’s Sustainable Development Scenario (SDS) offers a pathway for the global energy system to reach three strategic goals: the Paris Agreement’s well below 2°C climate goal, universal energy access and substantially reducing air pollution.

But based on existing and announced policies – as shown in the IEA's New Policies Scenario (NPS) – we are far from on track.

How do we get there?

Tracking Clean Energy Progress (TCEP) assesses the status of 45 critical energy technologies and sectors and provides recommendations on how they can get 'on track' with the SDS.
