Sustainability as a business philosophy and strategy

The firm was founded in 2005 on the principle that infrastructure investment should be long-term, responsible, and sustainable, with clear benefits to local communities. And, on the belief that the proper qualification of Environment, Social and Governance (“ESG”) and impact is essential to effective stakeholder management.

Meridiam has since developed robust ESG principles to include not only relevant global standards, such as the UN Principles of Responsible Investment (“UN PRI”) and the Equator Principles, but also to consider the ESG criteria of leading Development Finance Institutions (“DFIs”) (including the European Investment Bank (“EIB”), European Bank for Reconstruction and Development (“EBRD”) and the International Finance Corporation (“IFC”) Standards). These principles form the core of Meridiam’s sustainable development charter and are integrated throughout our investment and portfolio management process.

Our track record

By acquiring the status of certified benefit corporation, Meridiam went further in formalizing its sustainability strategy. Our  mission “delivering sustainable infrastructure that improves the quality of people’s lives” is now enshrined in its by-laws, confirming its commitment to achieving the United Nations Sustainable Development Goals (“UN SDGs” or “SDGs”) and a rigorous evaluation of the impact of our investments.

Our five pillars

Our five strategic pillars are:

  1. ”Deliver resilient infrastructure and develop resilient cities”
  2. ”Accelerate energy transition”
  3. ”Avoid & reduce emissions”
  4. ”Promote good work conditions, inclusion, diversity & gender equality”
  5. ”Protect & enhance biodiversity”


These pillars shape our organisation and our investment approach. They align with the UN Sustainable Development Goals and with our mission to improve the quality of people’s lives. What stands us apart is our pure focus on creating public infrastructure with a positive economic, social and environmental impact across Europe, Africa and the Americas.

Different countries and regions have a wide variety of social and environmental priorities. And every infrastructure project serves a different purpose – from the provision of quality healthcare to efficient mass transportation, or access to reliable, renewable energy. Each needs an individual approach linked to an overarching strategy.

Our pillars help turn our mission into deliverable goals, enabling us to target our initiatives and measure our firm’s impact on a global basis. They keep our sustainability strategy focused and help us identify ways to further improve our assets and our organisation

Meridiam’s Mission Committee meets at least three times a year to review and discuss Meridiam’s
achievements, challenges, and new initiatives aligned with the Mission Objectives.

Meridiam monitors its CSR performance every two years based on an assessment conducted by a third-party ESG/SDG ratings agency – Moody’s. Since 2020, this assessment is even more comprehensive and covers the whole sustainability approach of Meridiam and how it is implemented in all its activities.

The Sustainability Assessment was first carried out in 2020 and again in 2022 on Meridiam and its portfolios, and covered SDG-orientated topics. In the 2022 Sustainability AssessmentMeridiam obtained a scoring of 65/100 (versus an objective of 70), hence rating “Advanced”*, as was the case in 2020 (see Advanced Sustainability Rating by Moody’s and learn more here). 

[*] Recognition was received in December 2022. Members of Moody’s ESG Solutions are required to pay for their application to be analyzed and scored against Moody’s benchmarks.


Finally, in 2018 Meridiam created SIMPL. – the ‘Sustainability Impact Measurement Platform’ – an online platform that tracks and monitors the impact of assets against ESG targets and the United Nations Sustainable Development Goals (UN SDG). The interface is intuitive, easy to use and shows in real time the concrete impact of assets.

This monitoring and management tool is now a Software as a Service (SaaS), commercialized for financial market clients and corporates through an independent company*. Meridiam is now a client of SIMPL. and not the only user of this pioneering impact evaluation solution.

* joint venture between Meridiam and Blunomy (the specialized consultant with whom the tool has been historically developed).
