The report reflects a year of continued progress across the firm’s sustainability strategy, with a focus on environmental stewardship, social mobility and trust in the profession.

As a firm, we see ourselves as stewards of not only of our business, but also our communities and the environment. This report reflects the growing maturity of our sustainability approach and the steps we are taking to embed ESG considerations more deeply across everything we do. By strengthening our environmental foundations, investing in our people and culture, and championing quality and trust across our profession, we are focused on delivering impact that lasts.

Environmental progress and climate action

During the year, Forvis Mazars maintained its 100% zero‑waste‑to‑landfill status across UK offices, supported by ongoing investment in circular economy principles and sustainable buildings. The firm also maintained a ‘B’ rating from CDP for Climate Change disclosures, reflecting a consistent and structured approach to managing environmental impacts.

The report highlights continued progress towards the firm’s science‑based net zero targets, supported by enhanced emissions data capture, supplier engagement and a strengthened environmental management system.

Alongside this, the firm has released its first Climate‑related Financial Disclosure report, aligned with the TCFD framework, setting out its approach to managing climate‑related risks and opportunities.

Advancing social mobility and inclusion

Social impact remains a central pillar of the firm’s sustainability strategy. In FY25, Forvis Mazars supported 523 students through its partnership with IntoUniversity, helping young people from under‑resourced backgrounds access mentoring, skills development and insight into professional careers.

The firm also continued to make progress on diversity and inclusion, with female partner representation reaching 31%, up from 22% in 2021, reflecting sustained focus on progression, inclusion and leadership development.

Following more than 40 years of charitable giving, the Mazars Charitable Trust awarded £811,298 in grants in its final year, before transitioning to the newly established Forvis Mazars Foundation UK in April 2025. The Foundation will focus on improving social mobility across the UK through more targeted, impact‑led funding and skills‑based support.

Strengthening trust and audit quality

The report also underscores Forvis Mazars’ commitment to governance, quality and public interest outcomes. During the year, the firm became a founding member of the Centre for Public Interest Audit, reinforcing its role in championing audit quality and helping to restore trust across the UK audit market.

By continuing to invest in governance, risk management, technology and people, Forvis Mazars aims to support both its clients and the wider profession in navigating an increasingly complex and regulated environment.

The Forvis Mazars UK Sustainability report 2025 is published in accordance with recognised reporting frameworks and provides a transparent account of the firm’s progress, priorities and future direction.
