Your guide to sustainability, net-zero, ESG and environmental events in 2026.
Stay informed. Stay compliant. Stay ahead.
2026 is one of the most significant years yet for UK sustainability and climate action. New reporting requirements are coming into force, net-zero strategies are being tested against real targets, and the pace of policy change is accelerating. For businesses serious about the transition, knowing what is happening, and when, is a competitive advantage.
The SBS Sustainable Events Calendar brings together sustainability, net-zero, climate, ESG, circular economy and environmental events taking place across the UK, from flagship conferences and industry summits to global observance days, local authority workshops, policy launches, funded SME programmes and academic webinars.
Whether you are a sustainability professional building your CPD plan, a business leader mapping your compliance calendar, a procurement officer tracking PPN 006 developments, or an event organiser wanting to reach the UK's sustainability audience, this calendar is built for you.
