Just Transition Mechanism

The Just Transition Mechanism (JTM) is a European Union instrument designed to support the regions and communities most affected by the shift toward a climate-neutral economy. A key pillar of the European Green Deal, it aims to ensure the move to a low-carbon model is socially fair, protecting jobs and reducing regional inequalities so that, in the EU's words, no one is left behind.

Main objectives

  • Financial support: investment and grants for areas dependent on carbon-intensive industries such as coal mining, steel and cement.
  • Green jobs: industrial restructuring and diversification to create sustainable employment.
  • Economic development: regional competitiveness through innovation, digitalisation and the circular economy.
  • Social cohesion: training, reskilling and social protection for affected workers.

The three pillars

  1. Just Transition Fund (JTF): grants for economic diversification, worker reskilling and the transformation of carbon-dependent regions.
  2. InvestEU dedicated scheme: mobilises private investment for green and digital projects through guarantees and blended finance.
  3. Public Sector Loan Facility: combines EU grants with European Investment Bank lending to fund public investment in affected areas.

How regions access funding

Member States prepare Territorial Just Transition Plans identifying the regions most in need and the projects to support there. These plans are assessed by the European Commission, which allocates funding accordingly. Eligible projects span environmental rehabilitation, deployment of clean technologies, reskilling and entrepreneurship programmes, and sustainable mobility.

Connection with other EU policies

  • Climate neutrality by 2050: the JTM supports the EU's binding goal of climate neutrality under the European Climate Law.
  • Cohesion policy: it complements the European Regional Development Fund and the European Social Fund Plus.
  • Fit for 55: the JTM helps absorb the social impact of the package's 2030 emission-reduction targets.

Challenges

  • Adequate funding: matching resources to the scale of transition needs in high-unemployment regions.
  • Local engagement: active involvement of regional authorities to design effective projects.
  • Measuring results: clear indicators to track whether funded projects deliver lasting jobs and emission cuts.

Used effectively, the Just Transition Mechanism helps carbon-dependent regions transform their economies, create green jobs and strengthen social cohesion, making decarbonization fair and regionally balanced. At Manglai we help companies measure their carbon footprint and prepare for the regulatory and social dimensions of the climate transition. Discover how Manglai can help you.
