Hedera Guardian 3.0 - Sustainability for Enterprise

As climate standards grow in complexity, Hedera Guardian Ecosystem proudly unveils Hedera Guardian 3.0 — the cutting-edge upgrade powering the world’s largest open-source, digitized climate methodology library. This latest release evolves environmental data management into a future free from error-ridden PDFs and spreadsheets, replacing outdated tools with an advanced rule-based workflow engine that brings unprecedented accuracy and efficiency to climate action.

Legacy systems often struggle to deliver the transparency, traceability, and immutability that today's ESG reporting demands. The Hedera Guardian 3.0 addresses this gap, packed with enterprise-driven enhancements that empower businesses to achieve their sustainability goals confidently. New features—like fine-tuned permission settings, real-time analytics, visualization tools, and full API access—elevate open-source digital public goods to new heights, solidifying the Hedera Guardian as a leader in sustainable innovation.

To further accelerate continuous open source development and growth of the Hedera Guardian ecosystem, DLT Earth Initiative supporters, the HBAR Foundation, and Exponential Science are proud to announce their support of this growing ecosystem through key funding programs:

Community Generated Methodologies

‍

‍The Hedera Guardian 3.0 repository introduces open source implementations of numerous methodologies, including from Clean Development Mechanism (CDM), GHGP Corporate Standard, Global Carbon Council,  Gold Standard, Verra, iREC and others. This library is kept up-to-date by automatically testing each methodology implementation for compatibility with every new Hedera Guardian release. A real-world based test project (data) is used for such test runs, the results and artifacts are then automatically compared to the original. Community maintainers are notified and guided through to resolution if inconsistency or incompatibility is found.

‍

Enterprise-Grade Security

‍
A rigorous security audit completed in September of this year has enabled an array of targeted security enhancements for the Hedera Guardian 3.0 release that will improve trust and confidence in environmental integrity systems, so enterprises can manage their climate accounting processes without compromise or concern. Hedera Guardian 3.0 enables a step forward in transparency, context, and accountability with respect to climate and sustainability data and reporting tied to real world activities that generate trusted assets.
