ESG reporting software is a platform that helps organizations collect, validate, calculate, and disclose environmental, social, and governance (ESG) data to investors, regulators, and other stakeholders. At minimum, ESG reporting software manages GHG emissions inventory, energy and water consumption, waste generation, and social metrics. Leading platforms also support mandatory frameworks including CSRD, SEC climate disclosures, GRI, SASB, TCFD, ISSB/IFRS S1/S2, and CDP questionnaire responses within a single auditable data environment.
01 // Use Case: ESG & Sustainability
Software for users that need their disclosures to stand up to scrutiny
Mandatory ESG disclosure has arrived and the data quality standards it requires have changed everything. CSRD, SEC climate rules, and California SB 253 demand financial-grade GHG data, third-party assurance readiness, and audit trails that regulators and investors can actually follow. Locus delivers all of this from a platform whose GHG calculation engine has been guided by certified GHG reviewers for more than 14 years.
02 // WHY THIS MOMENT IS DIFFERENT
ESG reporting has moved from voluntary to mandatory
... and the data quality bar has moved with it.
Corporate sustainability reporting has been a voluntary practice for most of its history. GRI reports were published because sustainability-forward companies believed they should be. CDP questionnaires were answered because investors and customers asked for them. ESG ratings were optimized because they influenced institutional investment flows. In each case, the underlying data quality was largely self-governed. That era is ending.

03 // The Bar Has Been Raised
Organizations must adapt to more stringent, shifting requirements
CSRD, which took effect for Phase 1 companies reporting on 2024 data in 2025, requires external assurance and applies the same data governance expectations to sustainability information that financial statements carry. The SEC climate disclosure rules require third-party assurance of Scope 1 and Scope 2 GHG data for large accelerated filers. California SB 253 requires Scope 1, 2, and 3 disclosure for companies with more than $1 billion in revenue, with third-party assurance required for Scope 1 and 2 data starting with 2026 reporting.
For organizations that have been managing sustainability data in spreadsheets and manual collection processes, the assurance requirement is a forcing function. The people conducting third-party assurance engagements need a documentation trail from the reported GHG figure back to the meter reading, the fuel invoice, or the waste disposal record. Spreadsheets do not provide that trail. Locus Technologies does.
The real challenge in ESG reporting is not understanding the frameworks, it is getting the data
Most organizations with a sustainability team understand what CSRD requires and what the GHG Protocol says about Scope 3 accounting. The challenge is that the data needed to comply with these frameworks is scattered across operational systems that were never designed to support sustainability reporting: utility billing systems, fuel procurement records, RCRA waste manifests, laboratory-measured water quality results, supply chain management platforms, and fleet management software.

GHG emissions inventory -- Scope 1, 2, and 3
Locus manages Scope 1 (direct combustion, process emissions, refrigerant releases), Scope 2 (purchased electricity and heat, both location-based and market-based), and Scope 3 (value chain categories defined in the GHG Protocol Corporate Value Chain Standard) within a single calculation environment. Emission factor libraries include EPA, IPCC, and country-specific factors. All calculations are documented with methodology references and emission factor sources, which is the documentation trail that third-party assurance requires. Locus GHG software development has been guided by certified GHG reviewers for more than 14 years.

CSRD and ESRS compliance
Locus supports the full scope of CSRD data collection — double materiality assessment, climate-related risk and opportunity data (ESRS E1), water and marine resources (ESRS E3), resource use and circular economy (ESRS E5), and social and governance indicators — within a configurable platform whose templates can be updated by your team as ESRS requirements evolve. Locus CSRD customers include organizations in Phase 1 (FY2024 mandatory reporting) who have used the platform for first-year CSRD report preparation.

CDP questionnaire alignment
CDP Climate Change, Water Security, and Forests questionnaires are data-intensive exercises that draw on the same GHG, water, and waste data that CSRD and GRI reports require. Because Locus ESG software uses a unified data model, CDP-relevant data from environmental monitoring programs, utility integrations, and waste tracking is all available from the same validated environment that generates other disclosure outputs. CDP questionnaire preparation is supported through configurable data collection templates aligned to CDP's question structure.
GRI, SASB, TCFD, and ISSB/IFRS alignment
Locus ESG supports GRI Standards indicator data collection across environmental topics — GHG emissions (GRI 305), energy (GRI 302), water (GRI 303), and waste (GRI 306) as well as SASB sector-specific metrics for the industries Locus serves. TCFD-aligned climate risk and opportunity data collection and ISSB/IFRS S2 metric tracking are supported through the same configurable platform, allowing organizations that must simultaneously satisfy multiple voluntary and mandatory frameworks to work from one data set.
Supplier and value chain data
Scope 3 reporting under CSRD and the GHG Protocol requires data from suppliers, logistics providers, customers, and other value chain partners. Locus supports supplier data collection through configurable survey-style intake forms with conditional logic, automated completion reminders, and data validation before submission is accepted. Supplier response data flows directly into Locus's Scope 3 calculation environment, eliminating the manual collection-and-reconciliation cycle.
06 // Verification Experience
ESG software built by the people who review GHG inventories for a living
Locus is the only EHS and ESG software company whose GHG calculation engine has been shaped by certified GHG reviewers throughout its entire history — more than 14 years of direct emissions verification experience embedded in the platform. The professionals who developed the Scope 1/2/3 calculation logic hold doctoral, master's, and undergrad degrees in biochemical engineering, chemical engineering, and environmental engineering, and have prior careers managing GHG compliance for global oil, gas, and chemical companies.
This matters because third-party assurance of GHG data is no longer optional for the largest filers. Assurance providers look for exactly what those credentials represent: calculation methodologies aligned to recognized protocols, emission factor documentation, boundary definitions, and version-controlled records that can be traced from the reported figure back to the source data. Locus generates all of it — not as an add-on export, but as a property of how the platform stores data.

Frequently asked questions about ESG and sustainability reporting software
10 // FAQ
Organizations use a range of tools for ESG reporting, from basic spreadsheet models to purpose-built ESG software platforms. Among purpose-built platforms, leading options include Locus Technologies, which offers a unified EHS and ESG software environment with 14+ years of GHG verification expertise, plus several other enterprise ESG platforms. Key evaluation criteria include GHG calculation depth, assurance-readiness, data validation, framework coverage (CSRD, SEC, GRI, CDP, SASB), and whether the platform connects to operational data sources rather than requiring manual data entry.
Scope 1 emissions (direct combustion, process emissions, refrigerant releases) are tracked from fuel consumption records, process monitoring data, and refrigerant service logs. Scope 2 emissions (purchased electricity and heat) are tracked from utility bills and energy procurement records, with both location-based and market-based accounting supported. Scope 3 emissions across all 15 value chain categories require data from suppliers, logistics partners, product use data, and end-of-life disposal records, which are typically sourced from a combination of supplier surveys, purchase records, and spend-based estimation where primary data is unavailable. Platforms like Locus automate GHG calculations from these inputs using emission factor libraries.
The EU Corporate Sustainability Reporting Directive (CSRD) requires large companies to report on environmental, social, and governance data aligned with the European Sustainability Reporting Standards (ESRS). ESG software helps with CSRD compliance by managing double materiality assessment data, collecting ESRS-aligned indicator data from operational systems, generating audit trails that support external assurance, and producing disclosure-ready reports. Locus CSRD software flexes to support the full ESRS data collection scope with configurable templates that your team can update as ESRS requirements evolve.
These terms are interchangeable in most contexts. Both describe software platforms designed to help organizations manage and disclose their environmental, social, and governance performance. "Sustainability reporting software" is often used by organizations with a longer history of voluntary GRI or CDP reporting, while "ESG software" has become more prominent as investor-driven and mandatory ESG disclosure frameworks have expanded. Locus addresses both — it manages operational sustainability data for continuous internal tracking and generates disclosure outputs for every major voluntary and mandatory framework.
Third-party assurance of ESG data requires that assurance providers can trace reported figures back to their source data — verifying that the GHG calculation used the correct emission factor, that the Scope 2 calculation applied the right market-based accounting approach, and that the boundary definitions are consistent across reporting periods. Locus supports assurance by maintaining calculation methodology documentation, emission factor version history, data transformation records, and reviewer attribution on every record, and making it all accessible from the platform rather than reconstructed from spreadsheet archives.
Yes. Locus supports Scope 3 supplier data collection through configurable survey-style intake forms with automated reminders, conditional logic, and validation before submission is accepted. Supplier response data flows directly into Locus's GHG calculation environment for all upstream Scope 3 categories.
