ESG Reporting Guides: CSRD, ESRS & More

Reporting frameworks now cascade from the EU down to small suppliers: CSRD scope-3 requests, CDP scorecards, and EcoVadis ratings all reach firms that never expect regulation. These guides explain what buyers really ask for.

GRI Standards: The Reporting Framework You Can Use

You've decided to publish your first sustainability report. Maybe a customer asked, maybe a bank hinted, maybe your competitors all have one. The first decision is which framework to follow — and for most small businesses, the answer is GRI.

The Global Reporting Initiative's standards are the most widely used voluntary sustainability reporting framework in the world. Here's what they are, how they fit with the EU's mandatory regime, and how a small company puts them to work.

Scope 3: Your Customer's Spreadsheet Is Your Problem

The questionnaire arrives from your biggest customer: "Please provide your Scope 1, 2 and 3 emissions for the last financial year." Your company has never counted a kilogram of carbon. The questionnaire has a deadline.

Scope 3 is where small businesses meet climate reporting, usually unwillingly. Here's what it is, why it keeps landing in your inbox, and how to answer it without hiring a consultant.

SBTi for SMEs: Climate Targets Without the Circus

"Does your company have science-based targets?" If you sell to large organisations, you've seen that line in a tender or onboarding form. Most small companies skip it. A growing number answer it with a validated number, and the gap between the two groups is visible to buyers.

The Science Based Targets initiative (SBTi) is the body that validates corporate climate targets against what the science says is needed to stay within 1.5°C. And it has a dedicated SME route that a small business can genuinely complete. Here's what it takes.

CDP and EcoVadis: The Scorecards That Filter You

Two emails land in the same week. A large retail customer asks you to complete an EcoVadis assessment. Another asks you to respond to a CDP climate request. You are a 15-person company with no sustainability manager. Both emails are deadlines.

These two platforms are how big buyers screen suppliers today, and small companies lose business by treating them as optional admin. Here's how they work and how to survive them.

IFRS S1 and S2: What They Mean for a Small Firm

Walk into a bank meeting to renew a credit line these days and you may come out with homework: the credit officer wants to know your climate risks, your emissions and your reduction plan. The reason is less mysterious than it feels. Many banks now report under IFRS S2 themselves, and they need data from their borrowers to do it.

Nobody is going to make a 15-person workshop file IFRS S1. But the standards are becoming the grammar of sustainability data, and your business will be asked to speak it. The short version follows.

CSRD: EU Sustainability Reporting Requirements

If you think the CSRD is just an expanded version of the old NFRD, you're in for a shock. The Corporate Sustainability Reporting Directive (2022/2464) doesn't just expand the scope from 11,000 companies to 50,000 — it fundamentally changes what reporting means. 1,100+ datapoints. Double materiality. Limited assurance. iXBRL tagging. And for the first time, your sustainability data needs to stand up to external scrutiny.

The European Sustainability Reporting Standards (ESRS) are the rulebook, and they cover environmental, social, and governance topics in granular detail. If you already report under GRI or SASB, there's overlap — but the bar is significantly higher.

CSRD Compliance Software: Automate ESRS Reporting

If you're in scope for CSRD (250+ employees, €50M+ turnover, or €25M+ balance sheet), you're looking at 1,100+ datapoints across ESRS standards. That's not a number you spreadsheet your way through. The first wave of companies reporting on 2024 data already found that manual processes don't scale when you need auditable, double-materiality-assessed sustainability reports with XBRL tagging.

CSRD compliance software won't decide what's material for you, but it'll handle the data collection, validation, and ESRS tagging that makes the difference between a report that passes assurance and one that doesn't.

ESG Reporting Software: A Buyer's Guide for 2026

ESG reporting has moved from voluntary to mandatory for thousands of companies under the EU's CSRD, with the first compliance deadlines already passing in 2025 and phased rollout continuing through 2028. Whether you're subject to mandatory reporting or responding to supply chain requests from larger buyers, getting ESG data collection and disclosure right requires dedicated software.

ESG reporting software automates data collection across environmental, social, and governance metrics, maps them to reporting frameworks (CSRD, ESRS, TNFD, SASB, GRI), and generates auditable disclosures.

Modern Slavery Reporting Software

The UK Modern Slavery Act, Australia Modern Slavery Act, and Canada Bill S-211 require companies to publish annual statements detailing the steps they've taken to prevent forced labour in their supply chains. For companies subject to multiple jurisdictions, this means managing overlapping deadlines, varying requirements, and data from hundreds of suppliers — a task that quickly exceeds what spreadsheets can handle.

Modern slavery reporting software automates supplier due diligence data collection, risk assessment, statement generation, and cross-jurisdiction compliance tracking — replacing manual processes with a single auditable platform.

Biodiversity Software for TNFD & CSRD Reporting

Biodiversity reporting is rapidly moving from voluntary to mandatory. The Taskforce on Nature-related Financial Disclosures (TNFD) has set the framework, the EU CSRD requires biodiversity impact disclosures for affected companies, and the Kunming-Montreal Global Biodiversity Framework targets 30x30 protection by 2030. Companies must assess, disclose, and reduce their impact on ecosystems — and spreadsheets cannot handle the complexity.

Biodiversity impact software helps companies collect site-level ecological data, assess dependencies and impacts, generate TNFD-aligned disclosures, and track improvement over time.
