CSDDD for Construction Companies: 2026 Compliance Guide
- →Construction companies in CSDDD scope must report on ESRS modules E1, E2, E5, S1, S2, G1. Average sector readiness is only 24%.
- →Key compliance risks: Materials embodied carbon (Scope 3) and Worker safety (S1).
- →CBAM also applies to this sector — embedded carbon reporting required from 2026.
Which CSDDD requirements apply to Construction?
Construction companies, civil engineering firms, infrastructure developers and building contractors.
For CSDDD compliance, Construction companies must report on the following ESRS topical standards where material: E1, E2, E5, S1, S2, G1. The double materiality assessment will determine which of these modules require full disclosure.
Average compliance readiness across the Construction sector is currently 24% — significantly below the threshold needed for a clean assurance opinion. Most companies in this sector have work to do before their reporting deadline.
Key ESG risks for Construction companies
CSDDD requires Construction companies to disclose impacts, risks and opportunities across all material topics. The most commonly material topics for this sector are:
Materials embodied carbon (Scope 3)
Worker safety (S1)
Waste (E5)
Pollution (E2)
Construction companies that fail their double materiality assessment risk under-reporting material topics. Auditors pay particular attention to this sector's materials embodied carbon (scope 3).
Scope 3 emissions for Construction
Scope 3 emissions are typically the largest part of a Construction company's carbon footprint. The most material Scope 3 categories for this sector are categories 1, 3, 4, 11 under the GHG Protocol.
For CSDDD compliance under ESRS E1-5, you must:
1. Screen all 15 Scope 3 categories 2. Report on material categories with documented methodology 3. Set Scope 3 reduction targets for material categories 4. Obtain third-party assurance over your Scope 3 data
ESGMaster automates Scope 3 calculation for Construction companies using DEFRA 2026 emission factors.
Start with a spend-based Scope 3 screening across all 15 categories. This identifies which categories are material without requiring detailed activity data — you can then focus detailed calculation effort where it matters most.
CSDDD compliance roadmap for Construction
Phase 1 — Assess (Months 1–3) Determine your CSDDD scope status, complete a double materiality assessment, and run a gap analysis against ESRS E1, E2, E5, S1, S2, G1.
Phase 2 — Collect (Months 4–9) Build data collection processes for all material ESRS metrics. For Construction, focus on materials embodied carbon (scope 3) data first — it is typically the hardest to collect and the most scrutinised by auditors.
Phase 3 — Report (Months 10–12) Draft your CSDDD report, engage third-party assurance, implement XBRL tagging, and file with your national authority.
ESGMaster compresses this timeline by automating Phases 1 and 2 — delivering your gap analysis in 8 seconds and your draft report in hours.
ESRS modules for Construction — materiality guide
| ESRS Module | Topic | Typical materiality for Construction | Key data required |
|---|---|---|---|
| E1 | Climate change | High | Scope 1, 2, 3 GHG emissions |
| E2 | Pollution | High | Pollutant emissions, waste |
| E5 | Circular economy | High | Waste generation, circularity |
| S1 | Own workforce | High | Headcount, pay gap, turnover |
| S2 | Value chain workers | High | Supplier audits, child labour |

Frequently asked questions
Does CSDDD apply to Construction companies?
Yes, if your Construction company meets the CSDDD size thresholds: 1,000+ employees AND €450M+ net turnover (post-Omnibus). Even companies below these thresholds face CSDDD-equivalent data requests from their large customers.
Which ESRS modules must Construction companies report on?
Based on typical Construction business models, the most commonly material ESRS modules are E1, E2, E5, S1, S2, G1. However, you must conduct your own double materiality assessment — the final list depends on your specific operations and value chain.
What Scope 3 categories matter most for Construction?
The most material Scope 3 categories for Construction companies are categories 1, 3, 4, 11 under the GHG Protocol. Category 1 is typically the largest source of emissions in this sector.
How long does CSDDD compliance take for a Construction company?
From zero to first CSDDD report typically takes 12–18 months for Construction companies. The biggest time bottlenecks are Scope 3 data collection and third-party assurance provider engagement. ESGMaster reduces the data collection phase to weeks rather than months.
What does CSDDD compliance cost for a Construction company?
Consultant-led CSDDD compliance for Construction companies typically costs €100,000–€400,000 in year one, depending on complexity and number of subsidiaries. AI-powered platforms like ESGMaster reduce first-year costs by 60–80%.
