Managed sustainability & ESG reporting,done for you.
We handle the full reporting lifecycle — data collection across your operations and supply chain, emissions accounting, framework mapping, and the final disclosures under CSRD, CDP, TCFD, SBTi, and SFDR. Whether you are reporting for the first time or replacing a firm that overcharged you, we take it end to end.
Hydrus content is educational and workflow-oriented. Reporting obligations and assurance requirements should be confirmed with qualified advisors.
Frameworks and disclosures
One team runs every framework that matters to you, from the same governed set of data — so the numbers reconcile across disclosures instead of being rebuilt for each one.
CSRD / ESRS
The EU directive and standards, assessed through double materiality.
CDP
Disclosure preparation and the data behind a stronger submission and score.
TCFD / ISSB
Climate-related financial disclosure as the market moves to ISSB.
SBTi
Science-based target setting, validation, and progress tracking.
SFDR
Article 6, 8, and 9 disclosures for financial-services filers.
Scope 1, 2 & 3
Full-scope carbon accounting on the GHG Protocol, lineage preserved.
The reporting we run for you
CSRD reporting, done for you
We run the double materiality assessment, collect the ESRS data points, and produce the disclosure — audit-ready and traceable.
CDP, TCFD & SBTi submissions
We prepare the disclosures and submissions, and keep the underlying data consistent across every framework you file.
Scope 1, 2 & 3 accounting
We calculate all three scopes — including the supply-chain data problem in Scope 3 — and keep the method behind every number.
From spreadsheets to audit-ready
The hard part of reporting is not the chart — it is proving the number. We keep every figure connected to the source, method, and reviewer behind it, from collection through disclosure.
Collect
We pull data from operations, suppliers, invoices, utilities, and systems.
Calculate
We apply the right factors and methods, recording every assumption.
Evidence
Each figure keeps its source, method, and reviewer — ready for assurance.
Disclose
We produce the audit-ready report under the frameworks that apply to you.
Why managed beats software-only or consulting-only
Software-only
A platform you operate yourself. Powerful, but you still have to staff and run the reporting.
Consulting-only
Experts billed by the hour who leave when the engagement ends — and take the system with them.
Managed (Hydrus)
Software plus experts as one service: you get the finished disclosures and keep the system that produced them.
How an engagement works
You are not buying seats and a login you have to figure out. You are buying a managed program: we assess what you have to report, build the data foundation, run the reporting cycle, and maintain it as rules change. Pricing scales with the frameworks and scope you need — sized so a growing company can afford to do reporting right the first time.
- Assess — confirm your obligations and map the data.
- Build — stand up collection and the evidence trail.
- Report — produce audit-ready disclosures.
- Maintain — keep the program current as regulation moves.
Clients often come to us mid-crisis: a reporting deadline they are not ready for, a consulting contract they can no longer justify, or an investor questionnaire with no data behind it. Within one reporting cycle, the goal is to move from a reactive scramble to a managed program you can stand behind in front of an auditor. As we publish named case studies across financial services, manufacturing, and energy, this section will feature specific engagements and measurable outcomes.
Questions, answered
Is this software or a consulting service?
Both, deliberately. Hydrus provides an AI-native platform and expert practitioners as a single managed service — the leverage of software with the judgment of a consultant, without paying two vendors or managing the handoff.
We are already in spreadsheets. Can you take over?
Yes. Most clients start exactly there. We migrate your existing data, fill the gaps, and run the program forward so the spreadsheets become a starting point, not a permanent liability.
Which frameworks do you cover?
CSRD/ESRS, CDP, TCFD/ISSB, SBTi, SFDR, and scope 1, 2, and 3 emissions on the GHG Protocol. If a new regulation applies to your industry, we build it into your program.
How is this cheaper than a consulting firm?
Software does the repetitive data work firms bill hourly for, so our experts spend their time only on the decisions that need a human — comparable outcomes at a fraction of the cost.
Facing AI regulation too?
The same team and evidence engine stands up your EU AI Act program end to end — inventory, risk classification, controls, and audit-ready documentation.
