Enrico Letta, former Prime Minister of Italy, the author of the EU Single Market and Competitiveness Report (Much More Than a Market) and President of the Jacques Delors Institute, will return to the Green Transition Forum in Sofia this June for the second consecutive year.
His participation comes at a pivotal moment for European economic policy. Last week, the informal EU Leaders’ retreat placed the Single Market back at the centre of Europe’s strategic agenda. A suggestion made by Enrico Letta to the European leaders at the informal retreat shows us the path forward: the OneMarketAct. He proposes the move from 27 markets to one in strategic sectors in a way that must happen fast, with concrete deliverables in 2026, 2027 and 2028.
The discussions at the Green Transition Forum feed directly into a policy process that remains open and actively being shaped. At the Forum’s sixth edition, Letta will deliver a keynote address on Resetting Europe as a Leading Economic Power and lead an exclusive discussion with 100 of the region’s most influential CEOs and stakeholders.
Letta’s report, Much More Than a Market, published in April 2024, called for transforming the Single Market from a patchwork of national rules into an integrated economic space. Its key recommendations include completing the Single Market in sectors where barriers persist, a voluntary 28th regime allowing companies to operate across borders under one set of rules, the right to stay so that people have economic opportunity at home, and a 5th freedom of movement for research, innovation and investment.
The voice of Central and Eastern Europe remains underrepresented in the policy conversations shaping Europe’s economic future, and The Green Transition Forum is designed to change that. Letta will sit down with 100 key CEOs and stakeholders from across Central and Eastern Europe, for a structured discussion culminating in the Sofia Initiative for Competitiveness, focused on three topics.
- How to harmonise markets so that companies, talent and capital can move freely
- How to mobilise coordinated funding for startups and cross-border research
- How to accelerate permitting and standardisation to secure Europe’s industrial and technological position
The 2026 edition is expected to bring together C-level executives and institutional leaders for panel discussions, keynotes, and networking sessions over five days. The Forum’s key themes, Competitiveness, Innovation, and Security, will dive into how Europe can reinvent its industrial base, harness AI and digital transformation, and safeguard its infrastructure and people.
