In 2025 and early 2026, there has been a strong focus in EU decarbonisation policy on addressing gaps or challenges in Fit-for-55 legislation to enable the EU to meet their energy transition targets and strengthen energy security. Through initiatives such as the Clean Energy Investment Strategy, the EU has been explicit that annual investment must increase to nearly three times historical levels.

Supporting and accelerating local development is reinforced across the Clean Industrial Deal, Sustainable Transport Investment Plan and the European Grids Package, which collectively focus on removing development and investment barriers and using EU funding as a strategic lever to mobilise private investment.

This guide examines how these policy instruments interact and what they mean in practice. It explores the implications of CBAM, requirements for sustainable alternative fuels produced within and outside the EU, and the evolving hydrogen market - three years on from the adoption of RED III and other key Fit-for-55 legislation - including a focused perspective on Germany. 

Project planners, designers, developers, and investors in transport and energy infrastructure all need to be aware of the continually evolving legislative landscape to stay on the front foot to capture the opportunities ahead.
