IEA Technology Roadmaps


The International Energy Agency (IEA) is developing a series of global technology roadmaps, which set out scenarios for transforming particular energy sectors into low carbon sectors for 2050.

There is a pressing need to accelerate the development of low carbon energy technologies in order to address the global challenges of energy security, climate change and economic growth.

IEA, under international guidance and in close consultation with government and industry, is leading the process in developing global low carbon energy technology roadmaps covering the most important technologies. The overall aim is to advance global development and uptake of key technologies to reach a 50% reduction in energy-related CO emissions by 2050.

The roadmaps identify priority actions for governments, industry, financial partners and civil society that will advance technology development and uptake to achieve international climate change goals.

The vision for each roadmap is based on the ETP 2°C Scenario (2DS). This scenario describes how technologies across all energy sectors may be transformed by 2050 to give an 80% chance of limiting average global temperature increase to 2°C. The 2DS sets the target of cutting energy-related CO emissions by more than half by 2050 (compared with 2009) and ensuring that they continue to fall thereafter.

Each roadmap represents international consensus on milestones for technology development, legal / regulatory needs, investment requirements, public engagement / outreach and international collaboration. The following low carbon technology roadmaps are now available:
