What Sustainalize does

Sustainalize was a Dutch sustainability consulting firm headquartered in Utrecht, Netherlands, with additional offices in Brussels (Belgium) and Cologne (Germany). Founded in 2010, the firm advised nearly 200 organizations across technology, banking and finance, retail, aviation, and government sectors on measuring, disclosing, and responding to environmental, social, and governance (ESG) issues. Its service portfolio spanned four integrated pillars: ESG strategy development and execution, implementation support, external reporting, and impact measurement, covering topics such as climate change, biodiversity loss, resource availability, diversity and equality, human rights, and governance.

The firm's value proposition rested on in-house expertise in regulations, integrated reporting, and communications, delivered through a horizontal segmentation approach targeting enterprise clients. Sustainalize operated a consultative, enterprise field sales motion, with revenue generated through professional services engagements structured as project-based or retainer arrangements (specific pricing not publicly disclosed). The team grew to 30-50+ professionals in the years preceding full integration.

In April 2021, Sustainalize was acquired by ERM, the world's largest pure-play sustainability advisory firm, as a vehicle to expand ERM's continental European consulting capabilities. By September 2023, Sustainalize was fully integrated into ERM and retired as a standalone brand, with the 50+ professional team continuing to serve clients under the ERM name. As of the source date, Sustainalize no longer operates as an independent entity.
