Sustainability as a Business Philosophy

  • Meridiam is a pioneer in the Environmental, Social and Governance (ESG) approach, which we have applied systematically since our inception

Meridiam is certified Benefit Corporation™ (“B Corp”). The B Corp certification recognizes that Meridiam, together with its subsidiaries, has been designated as meeting high standards of social and environmental impact. Meridiam is one of a relatively small number of firms to have achieved B Corp certification.


  • In compliance with rigorous and recognized international standards

Meridiam meets the requirements of the ISO 9001: 2015 – which is a certification standard relative to quality management systems issued by the French Association for Standardization (AFNOR) (see certificate).  Meridiam’s investment process and risk management systems were certified ISO 9001:2008 first in 2012 and renewed each year since 2011.

Moody’s, one of Europe’s leading non-financial rating and auditing agencies, carried out a corporate social responsibility audit of Meridiam (as an organisation, rather than specifically as a fund manager) on a biannual basis until 2017. Following Meridiam becoming a société à mission, it was decided to conduct a more comprehensive SDG-orientated evaluation. To be performed on a biannual basis, a Sustainability Assessment was then carried out in 2020 and in 2022 on Meridiam and its portfolios, and covered SDG-orientated topics. Meridiam was rated “Advanced” on both assessments (see Advanced Sustainability Rating by Moody’s).

Meridiam also applies a proprietary methodology in relation to ESG and impact based on United Nations’ Sustainable Development Goals (SDGs).

Moreover, Meridiam was certified ISO 37001 – which is a certification standard relative to anti-bribery and corruption management systems issued by the French Association for Standardization (AFNOR)- in November 2021 (see certificate). Meridiam processes are therefore embodying business integrity aspects that prevent, detect and deal with corruption issues.

For the fifth year in a row, in 2021, Meridiam scored top quality ratings from the UN PRI. Meridiam scored 96% in Investment and Stewardship, comparable to a median score of 60%; and 96% in Infrastructure, where the median score is 71% (see UN PRI website;  Meridiam’s full assessment report is available on request).


  • Committed to creating positive impact within the United Nations Sustainable Development Goals (UN SDGs) referential

Meridiam is a member of the Association des sociétés à mission  and displays its commitments and achievements in favour of green and sustainable finance in the Paris financial centre as a member of Observatoire de la Finance Durable of Finance for Tomorrow.



Meridiam also became signatory of The Net Zero Asset Managers initiative in July 2021, committing to support the net greenhouse gas (GHG) emissions target and to support investments aligned with net zero emissions by 2050 or earlier. By joining the initiative, Meridiam specifically commits to prioritise the delivery of emissions reductions in the real economy, to address Scope 3 emissions in the portfolio, to create investment products aligned with net zero emissions and to facilitate increased investment in climate solutions. Meridiam’s commitment is made at the CEO level, with the express agreement of our CEO and founder, Thierry Déau.

The Net Zero Asset Managers initiative was launched in December 2020 and aims to galvanise the asset management industry to commit to a net zero emissions target. It is managed globally by six founding investor partner networks: Asia Investor Group on Climate Change (AIGCC), CDP, Ceres, Investor Group on Climate Change (IGCC), Institutional Investors Group on Climate Change (IIGCC) and the  Principles for Responsible Investment (PRI).



In 2021, Meridiam was certified « Best Place to Work » in France, USA, Canada, Senegal, Ethiopia, Turkey, Luxemburg, Austria, Jordan and in the Middle East.

The Best Places to Work program is the flagship employer of choice program driven in partnership with Best Companies Group. BCG is a well established US company with the purpose of identifying and recognizing best employers in many countries around the world and places of employment that are leading the way in defining the employee experience of the 21st century.

The Best Places to Work accreditations are recognized as the standard in workplace engagement. Every year, the program certifies and recognizes leading workplaces in many countries around the world, focusing on leadership, HR & people policies, compensation, benefits, teamwork & relationships, employee engagement, workplace & procedures and corporate social responsibility.
