🇪🇺 CSRD Compliance for EU Construction

Your customers need your carbon data.
We deliver it.

Skanska, BAM, and Vinci are filing CSRD reports now. Their Scope 3 emissions run through your supply chain — and they are asking every subcontractor for carbon data. We collect it, calculate it, and get it expert-verified in 90 days.

CSRD is here. Your customer's compliance depends on your data.

If you're a subcontractor to Skanska, BAM, Holcim, or Vinci — they are already required to report Scope 3 emissions. Your materials, fuel, and logistics are their Scope 3. They need your numbers. Most construction SMEs have no way to produce them.

📋

Wave 1 contractors are filing now

Skanska, Vinci, Holcim, BAM — companies with 500+ employees began mandatory CSRD reporting in 2025. Their Scope 3 is your emissions. If you can't provide carbon data, you become a compliance liability.

⏱️

Traditional consulting takes too long and costs too much

A freelance ESG consultant charges €15,000–€40,000 for a CSRD-ready emissions report. It takes 6–12 months. Most construction SMEs don't have the budget or the runway.

💶

Green financing now requires it

EU Taxonomy-aligned loans, BREEAM certifications, and public tenders with ESG scoring all require documented, verified emissions data. No data means no deal — on contracts and financing.

🏗️

Scope 3 is the part no one tracks

Materials (concrete, steel, timber), logistics, and waste represent over 80% of a construction company's carbon footprint. No generic ESG tool calculates it at the project level. We built one that does.

Your carbon footprint is now someone else's compliance problem.

That someone else is your customer. Large contractors filing CSRD reports need your Scope 3 supply chain data to complete their own disclosures. Subcontractors who can provide verified data win the contract. Those who can't get replaced.

CSRD Wave 2 started in 2026 for companies with 250+ employees. The construction companies getting their data in order now will be ahead when Wave 3 hits 50+ employee firms.

Verified ESG report in 90 days. Guaranteed.

We are not a dashboard. We are not a consultant. We are AI-powered reporting infrastructure that takes your operational data — fuel receipts, material invoices, utility bills — and produces a Scope 1, 2, and 3 emissions report that any customer, bank, or auditor can verify.

Expert validation layer

Every report is reviewed by a CESGA- or BREEAM AP-certified ESG consultant before delivery. Not a confidence score. Not an AI-generated disclaimer. A signed, methodology-disclosed report that holds up to procurement scrutiny, green loan applications, and third-party audit.

Our validators include certified experts from
DGNB · DGBC · SGBC · FIGBC · ÖGNI · BGBC

Common questions.

Which companies need CSRD?

Wave 1 (reporting from 2025): companies with 500+ employees. Wave 2 (reporting from 2026): companies with 250+ employees or €40M+ turnover. Wave 3 (reporting from 2027): listed SMEs with 50+ employees.

But even if CSRD doesn't apply to you yet, your large customers who are filing now need your Scope 3 supply chain data. That pressure is commercial and it's real today.

We don't have our emissions data. Can you still help?

That's exactly what we do. We start with spend-based estimates derived from your invoices and procurement data — even an estimate with disclosed methodology is better than silence. We document everything transparently so your number is defensible to customers, banks, and procurement committees.

How long does it take to get started?

After signing, we schedule an onboarding session within 5 business days. Data collection templates are deployed the same week. Preliminary emissions baseline within 30 days. Full verified report within 90 days — guaranteed or full refund.

Is the report audit-ready?

Yes. Every report includes: full emission factor references (GHG Protocol, IPCC, EU grid), methodology disclosure for each Scope, data quality notes, and sign-off from a certified EU ESG expert (CESGA or BREEAM AP credential). This is what procurement committees, banks, and CSRD auditors need.

What's Scope 3 and why does it matter for construction?

Scope 3 covers indirect emissions in your supply chain — primarily materials (concrete, steel, timber), logistics, and waste. For a typical construction company, Scope 3 represents over 80% of the total carbon footprint. Without it, your number isn't credible to customers, banks, or auditors.

We already use sustainability software. Is this different?

Most sustainability software gives you a dashboard — you still have to do the work. We deliver a completed, expert-verified emissions report. The question is: does your current tool give you a signed report you can hand to a CSRD auditor, a procurement committee, or your bank's green loan officer? If not, that's the gap.

Ready to get your emissions data in order?

Book a 10-minute discovery call. No pitch — we'll ask two questions, show you what a finished report looks like, and tell you if we're the right fit for your situation.
