ICCA proudly announces a landmark sustainability partnership with EarthCheck, unveiled during the 64th ICCA Congress in Porto, Portugal. This collaboration marks a pivotal moment in ICCA’s mission to embed sustainability and measurable climate action across the global business events industry.
Under a new two-year agreement, EarthCheck becomes ICCA’s sustainability partner, reinforcing ICCA’s commitment to reducing environmental impact, strengthening best practices, and empowering its global network to take meaningful action.
To launch the partnership, EarthCheck applied its EventCalculator tool to measure the carbon footprint of the 2025 ICCA Congress in Porto. These insights will inform ICCA’s long-term sustainability roadmap and set clear, evidence-based targets aligned with the Net Zero Carbon Events initiative.

EarthCheck CEO Stewart Moore said: “Both ICCA and EarthCheck recognise that sustainability must be measurable, transparent, and actionable. This partnership strengthens the industry’s ability to act with purpose. ICCA connects a vast global community, and EarthCheck brings the metrics and methodology to support credible action. Together, we can help destinations and organisers make informed decisions that create real impact.”
The partnership will see ICCA and EarthCheck collaborate on sustainability strategies, events, training, and communications, ensuring sustainability principles are integrated across ICCA’s operations and major activities. ICCA members will also gain access to EarthCheck’s guidance, tools, and certification support to advance their own sustainability goals and reporting practices.
Together, ICCA and EarthCheck aim to accelerate progress across the global business events community, demonstrating how science-based frameworks and collective leadership can help the sector thrive in a low-carbon future. This collaboration underscores ICCA’s vision for a more resilient, inclusive, and sustainable global events industry — one where progress is measured, shared, and celebrated.
