De Duurzame Adviseurs

What De Duurzame Adviseurs does

De Duurzame Adviseurs B.V. (DDA) is a Netherlands-based sustainability consulting firm founded in 2011 and headquartered in Amersfoort, delivering advisory and certification support to enterprises, governments, and SMEs across the Dutch and Belgian markets. Its service portfolio is organized around three pillars — CO2 (footprint assessment and CO2-Prestatieladder certification for both the Netherlands and Belgium), ESG (strategy, B Corp, EcoVadis, VSME, and circular economy), and CSRD compliance (including a CSRD Kickstart onboarding product) — executed through a proprietary "Data, Drive & Actie" methodology that emphasizes practical action plans over lengthy policy documents.

The underlying technology is human-delivered professional services: there is no proprietary software platform, and the firm relies on standard web analytics (Google Analytics, Piwik) and lead-generation tooling (Leadinfo) rather than purpose-built applications. Knowledge content — a knowledge bank, 10 years of webinar programming, the Positieve Impact Podcast, and whitepapers — functions as a community-led top-of-funnel acquisition engine, supported by SEO, email, and direct sales.

DDA operates a project-based, quote-priced professional-services revenue model with multi-year contracts. Distribution runs through dedicated CO2 and ESG account managers, inside-sales follow-up on website quote requests, and event-driven engagement (webinars, podcasts). Since 2026, the firm has operated as a subsidiary of Apave Impact, a French TIC conglomerate, which provides international reach and capital for further expansion. The team numbers approximately 25 employees and freelancers, and the firm has supported 1,500+ clients (including 63+ governments and municipalities) with an 8.5 customer-satisfaction score.
