Forward Firms is Forward Law Review’s annual review of leading sustainability and ESG law practices. Based on detailed firm submissions and FLR’s own reporting, it profiles firms we regard as credible advisers for sophisticated sustainability-related legal work. The 2026 edition brings together 30 firms from across Europe, North America, Latin America and Asia-Pacific, offering a snapshot of a market shaped by energy transition, regulatory change, investor scrutiny and climate-related disputes. Read together, the profiles reveal how sustainability law is taking shape across jurisdictions, sectors and practice areas.
