The Global Legal Entity Identifier Foundation (GLEIF) and Global Energy Monitor (GEM) have completed the first certified mapping between GEM Entity ID and the Legal Entity Identifier (LEI), making it possible to trace the legal ownership of energy assets worldwide through standardized, openly accessible data. The first open mapping file will be published in June 2026, with integration into GLEIF’s API and LEI Search to follow.
There are hundreds of thousands of energy assets globally – such as coal mines, combustion power plants, iron and steel plants, cement plants, oil extraction fields, and gas pipelines – which often have complex and opaque ownership arrangements. Consequently, it has proved difficult for organizations and regulators to fully assess exposure and risk.
By increasing transparency of energy asset ownership, the mapping gives companies a direct way to meet climate-related reporting and due diligence requirements under frameworks such as the EU Corporate Sustainability Due Diligence Directive (CSDDD). It also supports investor portfolio screening against verified ownership data and helps regulators cross-check reported ownership structures against authoritative open-source data.
It also meets growing regulatory and market demand for high-quality, interoperable, open data that can be used consistently across markets and jurisdictions. This highlights the growing applicability of the Global LEI System as an internationally recognized and standardized organizational identity management infrastructure and global Digital Public Infrastructure (DPI), which connects with other authoritative data sources to extend access to trusted information globally.
Alexandre Kech, GLEIF CEO, said: “Directly linking real-world assets to the legal entities that own them is the only way to really understand the world’s energy system. Our collaboration with GEM shows how trusted organizational identity data is delivering immediate value to streamline compliance with climate-related disclosure and due diligence obligations, while demonstrating how the broad public good provided by the Global LEI System is being extended to promote greater transparency, openness, and accountability throughout the global economy.”
Anna Mowat, GEM Ownership Project Manager, comments: "We are committed to making reliable, high-quality energy data freely available to the world. Mapping our open datasets to the LEI furthers this mission, marking an important step forward that will enhance visibility, usability, and impact to help enable a sustainable future."
GEM is the first Global Open Data Integration Network (GODIN) member from the energy sector to complete a mapping certification. Launched in 2025, GODIN is a GLEIF-led initiative that aims to enhance global data interoperability and accessibility by aligning open data sources to recognized global frameworks. This transforms siloed data into interoperable, actionable information that can be used across markets and jurisdictions.
GLEIF’s free LEI Mapping Certification service is key to enabling this interoperability. It overcomes the fragmentation risks posed by a single legal entity being associated with multiple identifiers by linking existing identifiers to the globally recognized LEI. In addition to GEM, GLEIF has also certified mapping relationships between S&P CIQ Company ID, SWIFT’s Market Identifier Code (MIC) and Business Identifier Code (BIC), the Association of National Numbering Agencies’ (ANNA) International Securities Identification Numbers (ISIN), and Qichacha’s QCC Code.
