Why data security matters in carbon accounting software
Data security in carbon accounting software rarely comes up in sales demos, yet it decides whether your emissions data can be trusted, audited and shared. Your carbon inventory holds energy bills, production volumes, supplier spend, site locations and sometimes the commercial terms behind them. In the wrong hands that is competitive intelligence. In a poorly controlled system it is a figure nobody can defend in front of an auditor.
Why carbon data is sensitive data
Emissions figures look harmless on their own, but the activity data behind them is not. Monthly electricity use reveals production rates. Fuel and refrigerant records show which plants run hardest. Supplier lists and purchase volumes expose your supply chain. For a financial institution, portfolio emissions sit next to loan balances and counterparty names.
Climate disclosures are also moving into regulated territory. Under frameworks such as ESRS and IFRS S2, emissions sit alongside financial statements and are increasingly subject to assurance. That means the controls around the data matter as much as the numbers themselves. A GHG inventory that anyone could edit without a trace will not survive a serious verification.
Seven controls that protect carbon data
1. Data residency
Many organisations, especially in the public sector, financial services and the Middle East, need data to stay in a particular country or region. A good platform lets you choose where it is hosted, or run it on your own infrastructure, so data never leaves the jurisdiction you have approved.
2. Encryption in transit and at rest
Every connection should use modern TLS, and stored data — including uploaded evidence such as bills and invoices — should be encrypted at rest. Evidence files are often overlooked; they carry the most detail of all.
3. Strong identity: MFA, SSO and SCIM
Passwords alone are not enough for a system that feeds regulatory reports. Multi-factor authentication should be standard. Single sign-on with your identity provider means people use their company login, and SCIM provisioning means leavers lose access the moment HR closes their account.
4. Role-based access
A facility manager should see their own sites. A data preparer should enter data but not approve it. A verifier should read but never change anything. Suppliers using a supplier portal should only ever see their own submissions. Role-based access scoped by entity, site and action enforces this.
5. A complete audit trail
Every entry, every edit, every change to an emission factor or setting should record who did it, when, and what changed from and to. This is the foundation of assurance: a verifier can follow any number back to its source.
6. Four-eyes approval
Maker–checker controls mean one person enters and a different person approves. For sensitive actions — base-year restatements, materiality decisions, carbon credit retirements — a second approver should be mandatory. It stops honest mistakes as well as deliberate ones.
7. Tenant isolation and certified deletion
In a multi-client platform, each client's data must be logically separated, with dedicated deployments available where needed. And when a contract ends, you should receive confirmation that your data has been deleted — ideally a destruction certificate.
A checklist for evaluating vendors
When you assess carbon accounting software, ask these questions in writing and keep the answers with your procurement file:
- Where will our data be hosted, and can we choose the country or host it ourselves?
- Is data encrypted in transit and at rest, including uploaded documents?
- Do you support MFA, SSO with our identity provider and SCIM provisioning?
- Can access be limited by entity, site and action? What can suppliers see?
- Is every change logged with the before and after values, user and time?
- Which actions require a second approver, and can we configure thresholds?
- How is our data separated from other clients'?
- Are emission factors versioned, so past results can be reproduced?
- What happens to our data at contract end, and will you certify deletion?
- Which independent certifications or penetration tests can you share, and when were they last done?
Answers to the last question vary widely between vendors. Ask for dates and scope, not just logos.
How EKOTRACE approaches security
EKOTRACE is built so that controls and calculations live in the same place. Clients can host in their chosen region or on their own servers. MFA, SSO and SCIM are available as standard. Access is scoped by role, entity and site, and suppliers only see their own data in the supplier portal. Every entry carries its evidence and a full change history. Entries & approvals enforce maker–checker review, and critical actions require a second person. Emission factors are versioned, so any figure in a report or verifier pack can be reproduced. At contract end, data is deleted and a destruction certificate issued. You can read more on our security page.
Frequently asked questions
Is carbon data personal data?
Mostly not, but it often includes names, e-mail addresses and travel records, which are. Treat the platform as you would any system holding business-confidential and some personal data.
Do we need data residency?
It depends on your regulator, sector and internal policy. Public bodies, banks and companies in several Gulf and Asian markets often do. Check before you sign.
Does security slow down data collection?
Not when it is designed in. SSO makes logging in easier, and clear roles mean people only see what they need.
