Building a Backbone for ESG Data and Reporting

Updated by Onye Dike on November 20th, 2025
Anthesis Mero is an ESG data management and reporting platform that consolidates scattered sustainability information into a single, auditable system. Developed by conTREEbute with Celsia and now part of Anthesis Group’s digital suite, it targets organisations with complex disclosure duties, from utilities and retailers to financial institutions and private equity portfolios. By digitising workflows that once depended on spreadsheets and email, Mero helps teams manage indicators across environmental, social and governance topics, align data to multiple frameworks over time, and surface trends that support strategy, risk management, performance tracking and board-level decision-making across global operations and investments.

Core Features

Mero approaches ESG information management as a data backbone rather than a stand-alone reporting front end. It is delivered as a cloud-based SaaS platform that aims to bridge the technological gap between sustainability strategy, day-to-day data collection and evolving disclosure frameworks, while remaining closely integrated with Anthesis’ advisory services. Against this backdrop, some of its main features are:

  • Centralised ESG data hub: Provides a unified cloud platform for environmental, social and governance indicators, replacing spreadsheets and email chains so organisations can view portfolio and entity-level data in one place with improved traceability.

  • Configurable data collection workflows: Uses configurable forms and workflows to gather ESG information from business units and portfolio companies, standardising questionnaires while allowing industry-specific fields and enabling ongoing, not just annual, monitoring.

  • Multi-framework reporting engine: Maps data once and produces outputs aligned with multiple regulatory and voluntary standards, helping organisations prepare reports for frameworks such as CSRD-related ESRS, ISSB-aligned standards and broader ESG disclosure requirements.

  • Systems and analytics integrations: Integrates with existing systems and BI tools so that transactional data can feed into dashboards and advanced analytics.

  • Governance, controls and audit trail: Supports data validation steps, approvals and role-based access, aligning with assurance providers and audit processes by maintaining clear ownership, sign-off flows and documentation of changes across reporting cycles.

  • Secure, scalable cloud service: Delivered as ISO-certified, high-security cloud software with 24/7 availability, designed to scale across multiple countries and subsidiaries while maintaining full control and traceability of ESG data.

Closing Insights

Mero began as a joint initiative between Colombian consultancy conTREEbute and energy company Celsia, replacing fragmented ESG spreadsheets with a single auditable platform. Now part of Anthesis Digital, it functions as Anthesis’ core ESG information backbone, helping organisations consolidate indicators and respond consistently to evolving disclosure rules across markets. Celsia, retailer Grupo Éxito and financial institution Corficolombiana illustrate Mero’s breadth, using it to centralise data, automate portfolio collection and power dashboards for sound management decisions and stakeholder communications.

Recent developments include integration into Anthesis through the conTREEbute merger, an international trademark filing in 2024, and expansion via country-specific Mero offerings and partnerships. Operated alongside Anthesis’ reporting and private-capital advisory teams, Mero combines configurable workflows, system and BI integrations, and embedded expert support making it a strong option wherever ESG and regulatory oversight must rest on robust traceable data.
