CSRD in Professional Services: What Office-Based SMEs Need to Know

Professional services firms — consultancies, IT and software businesses, engineering and design practices, marketing agencies, accountancy, legal, and advisory firms — usually have small direct emissions but face heavy supplier-questionnaire pressure from larger clients. A small consultancy serving a few CSRD-reporting banks can receive five or six different ESG questionnaires a year. The substance of what is asked overlaps; the formats almost never do.

Under the 2026 Omnibus revision, CSRD applies only to undertakings with more than 1,000 employees and more than €450 million net turnover. Almost every professional services SME is well below that threshold. The Voluntary Sustainability Reporting Standard for SMEs (VSME) gives small and growing businesses a single, comparable disclosure set that most CSRD-reporting clients will accept, and the Omnibus value-chain cap prevents in-scope clients from demanding more than VSME requires from sub-1,000-employee suppliers.

Typical Data Requests from Professional Services Clients

• Total electricity — kWh per office per year, split renewable vs non-renewable, mapped to VSME B3
• Scope 1 and Scope 2 emissions — usually small (no fleets, no on-site combustion in most cases) but still required
• Business travel — flights, rail, car rentals, and hotel nights — typically the largest emissions category for a consultancy or law firm (Scope 3 Category 6)
• Employee commuting — split by mode (car, public transport, cycle, walk) and by hybrid working share (Scope 3 Category 7)
• Cloud and IT services — emissions from purchased SaaS, cloud hosting, and data-centre services, mapped to Scope 3 Category 1 (and sometimes Category 8 for leased IT assets)
• Workforce data — headcount, gender split, training hours, sickness absence, collective bargaining coverage (VSME B8–B10)
• Anti-corruption — convictions and fines record (VSME B11), or an explicit "none" statement

Two Paths Forward

Your business can pursue full CSRD if legally required, or adopt VSME voluntarily for customer questionnaires. Almost all professional services SMEs should start with VSME Basic (B1–B11), which usually fits in a 3–8 page PDF. Once it is written, the same document answers most client requests with at most a few specific add-ons. Adding optional Comprehensive Module (C1–C9) datapoints — particularly Scope 3 — makes sense for firms whose largest clients are banks, insurers, or other heavily regulated sectors.

The articles below cover the practical realities — how to estimate office electricity when the landlord controls the meters, how to track business travel without rebuilding your expense system, how to handle Scope 3 for cloud and SaaS suppliers, and how to keep one VSME document up to date across multiple client questionnaires.
