GLOBAL – ESG Book, a global leader in sustainability data and technology, and Arcesium, a leading global financial technology firm, today announced a new partnership to deliver market-leading sustainability data for institutional investors.

ESG Book’s data solutions are now available through Arcesium’s scalable, cloud-native technology for next-generation sustainability analysis on over 50,000 listed corporations globally.

Market demand for high-quality, granular ESG and climate data continues to grow sharply, driven by increasing sustainability regulations worldwide. More than 90% of executives expect to meaningfully increase their spending this year on ESG data, according to a recent Bloomberg survey*. The vast majority of respondents believe ESG data investment is required to keep pace with competitors or to develop a competitive advantage.

Through the new integration, Arcesium’s and ESG Book’s mutual clients will gain access to a range of sustainability insights for security selection, portfolio management, and analytics. ESG Book’s scores, raw attributes, SFDR, and emissions datasets will be integrated with Arcesium’s highly configurable Financial Data Stack and purpose-built data platform, AquataTM, enabling institutions to confidently make investment decisions from a synchronized source of data.

David Nable, Head of Client and Partner Development at Arcesium, said, “By combining ESG Book’s high-quality data with Arcesium’s unparalleled technology, we’re arming our clients with the tools to manage the increasing complexity of sustainable investing. With powerful tools to ingest, unify, analyze, and report on data, this integration is designed to enable institutional investors to thoughtfully deploy and manage their sustainable investment initiatives.”

Dr. Daniel Klier, CEO of ESG Book, said, “Demand for high-quality, granular ESG data is soaring across financial markets, driven by a growing need for investors to fulfill regulatory requirements and meet client demand for greater transparency on non-financial issues. We are delighted to partner with Arcesium, and enable clients to access high-quality, fully traceable ESG data for better portfolio management and risk analysis.”

ESG Book’s data-driven solutions have been developed as a response to many of the current market challenges around sustainability ratings, including opacity around score methodologies and underlying data, lack of standardization, and limited ability to measure industry- and sector-specific metrics. Arcesium’s unified, domain-aware platform built with industry-specific capabilities is designed to harmonize massive amounts of disparate data and deliver unparalleled speed, accuracy, and decision-making capabilities. Together, Arcesium’s and ESG Book’s cloud-native technologies will enable institutional investors to access, manage, and disclose ESG data in a digitized, secure, and centralized way.
