Independent Sustainability Assurance Services
Atveris delivers independent sustainability assurance and verification services aligned with leading reporting frameworks and regulatory requirements. We support organizations in validating ESG data, sustainability disclosures, and climate‑related information across both voluntary and mandatory reporting contexts.
Our work covers ESG KPIs, sustainability and climate reporting, regulatory disclosures, product and value‑chain claims, and assurance readiness. We focus on transparent methodologies, robust evidence, and practical recommendations that support compliance, consistency, and long‑term reporting maturity.
“Our approach to sustainability assurance is grounded in independence, transparency, and proportionality. We focus on applying the right level of rigor for how sustainability information is used, while remaining pragmatic, collaborative, and outcome‑focused.”
