isla releases European Temperature Check Report 2025, the first data-led snapshot of carbon emissions across European business events

Event sustainability body isla today publishes its European Temperature Check 2025, a follow-up to their 2023 UK-only study and the most comprehensive look yet at carbon impacts in the European events market.

Launched at isla’s Made Possible Festival (6 May, Barbican Centre), the study analyses data from almost 1,000 events measured in TRACE, isla’s carbon measurement platform, and blends it with survey responses and in-depth interviews from brands, agencies, venues and suppliers.

Report highlights include:

• Verified emission benchmarks for conferences, exhibitions, meetings and brand experiences across Europe
• Hotspot analysis that pinpoints high-impact reduction opportunities in energy, travel, and materials
• Clear guidance on how legislation will impact businesses 
• Insights on how extreme weather and supply-chain risks are reshaping business travel and event design
• Practical actions for building climate-resilient events

Anna Abdelnoor, CEO & Founder, isla: “As climate pressures intensify, the sector faces growing urgency to adapt to a changing world. Our new European report gives the event industry the data to act. We analysed almost 1000 TRACE-measured events and took insights from a Europe-wide survey to set clear benchmarks and pinpoint fast, practical opportunities to act with impact. Without comprehensive measurement, we cannot track trends, set realistic benchmarks, or drive evidence-based change. Our ambition is to make ‘start measuring’ a given, not a rallying cry.”

Why it matters:

• Legislation is tightening. Disclosure and circular-economy rules now carry real deadlines.
• Climate impacts are immediate. 2024 was the hottest year on record; extreme weather already disrupts programmes and supply chains.
• Data drives decisions. Without verified figures and credible targets, real progress to reduce collective environmental impact cannot be made 

The European Temperature Check Report’s purpose is to transparently share information, providing carbon data to empower conversations to accelerate industry-wide progress and highlights the growing need for formal reporting to comply with regulations, retain clients, and attract new business.
