Sustainability data and technology company ESG Book announced today the appointment of Leon Saunders Calvert as Chief Product Officer. Saunders Calvert is the current Head of Research and Portfolio Management at the London Stock Exchange Group (LSEG) and will join ESG Book in October.

In his new role, Saunders Calvert will be responsible for leading the expansion of the company’s product suite and driving its market differentiation through next-generation sustainability solutions.

Saunders Calvert has previously served as Head of Sustainable Investing, Lipper, and Research at financial markets data and infrastructure provider Refinitiv, prior to its acquisition by LSEG, and ran the M&A and Capital Raising business at Thomson Reuters. At Refinitiv, he launched the Sustainable Leadership Monitor with the World Economic Forum, acted as formal advisor to the Chartered Institute for Securities & Investment in the creation of the Certificate in Climate Risk, and he also serves on the Advisory Board of the online mission empowerment platform Aidhub.

Dr Daniel Klier, CEO of ESG Book, said:

“I am delighted to welcome Leon to the team to lead our product development and expansion. He joins ESG Book with a strong track record as a driver of growth and innovation in market data businesses, with demonstrable expertise in delivering industry-leading sustainability products.”

The appointment follows ESG Book’s announcement last month that it has raised $35 million in a Series B funding round aimed at advancing the adoption of its ESG data platform and helping the company expand into new product areas.

The ESG Book platform was launched in December 2021 by an alliance of financial institutions, investors, and sustainable investment-focused service providers, aiming to provide a central source for accessible, transparent, and comparable ESG data. ESG Book was made to be available to all companies, investors, standard-setters, and stakeholders, and supports the principles of the UN Global Compact, which encompass human rights, labor, environment, and anti-corruption.

Saunders Calvert said:

“ESG Book is extremely well positioned to enable the mainstreaming of sustainable outcomes into financial markets. Rich data and analytics are needed to empower financiers and investors to raise and allocate capital towards economic decarbonisation and to companies and institutions who demonstrate the values of a fair society. ESG Book has a high quality team, strong IP, and a business model primed for value creation to our customers. I am incredibly excited to help the firm drive further differentiation with our product suite.”
