Leon Saunders Calvert to join ESG Book

Saunders Calvert currently runs the Research and Portfolio Management business at the London Stock Exchange Group (LSEG), where he has been leading the desktop business servicing the front office institutional investment management community. He was previously Head of Sustainable Investing, Lipper, and Research for Refinitiv (now an LSEG business), and before that ran the M&A and Capital Raising business at Thomson Reuters.

His appointment is part of the scaling of ESG Book's services worldwide, as the company accelerates its growth in response to increasing client demand for technology enabled ESG data solutions. The announcement follows ESG Book's $35m Series B, involving three of the world's leading sustainability-conscious investors, to fuel adoption of its industry-leading data platform, and further the company's continued expansion into cutting-edge new products areas.

ESG Book's cloud-based platform makes sustainability data accessible, consistent, and transparent, enabling financial markets to allocate capital towards more sustainable and higher impact assets. Covering over 25,000 companies globally, ESG Book enables companies to be custodians of their own data, provides framework-neutral sustainability information in real-time, and promotes transparency.

Leon Saunders Calvert, ESG Book's incoming Chief Product Officer, 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."

Dr Daniel Klier, CEO of ESG Book, said: "ESG Book's technology capabilities enable clients to meet increasingly complex sustainability requirements, driven by data that is comparable, transparent, timely, and actionable. As we look to disrupt the ESG data market with innovative, next-generation solutions, 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."

Since taking on the role of Head of Sustainable Investing at Refinitiv, Saunders Calvert launched the Sustainable Leadership Monitor with the World Economic Forum, acted as formal advisor to the Chartered Institute for Securities & Investment (CBI) in the creation of the Certificate in Climate Risk, and serves on the Advisory Board of Aidhub.
