About Flag
Flag is a London-based sustainability communications agency that partners with corporations, financial institutions, and global brands navigating the complexities of environmental, social, and governance (ESG) reporting and stakeholder engagement. Founded in 1984, the agency has evolved from a traditional public relations firm into a specialist consultancy focused on the intersection of sustainability strategy, reporting, and creative storytelling. Their client base spans multinational enterprises and organizations seeking to articulate their sustainability journey with credibility and impact.
Strategic Sustainability Communications and Reporting
At its core, Flag helps organizations translate complex sustainability data into clear, compelling narratives that resonate with investors, employees, and regulators. The agency's expertise spans the full spectrum of ESG reporting frameworks, including the International Sustainability Standards Board (ISSB), the Corporate Sustainability Reporting Directive (CSRD), the European Sustainability Reporting Standards (ESRS), and the Global Reporting Initiative (GRI). Flag also specializes in double materiality assessments, a critical process under CSRD that helps companies identify and prioritize the sustainability issues most relevant to their business and stakeholders. Beyond compliance, Flag focuses on building trust through transparent, data-driven storytelling that demonstrates genuine commitment to sustainability goals.

The agency provides end-to-end support for sustainability communications, including copywriting, design for print and web, digital video production, and web development for digital engagement.

Flag also develops sustainability campaigns and marketing communications that engage employees, customers, and communities.
