Sustainable Events: Choosing a Green Hotel for Your Conference

To choose a genuinely sustainable hotel for your conference, look for third-party certifications (ISO 20121, EU Ecolabel, Green Key, LEED), ask for measurable sustainability data (energy sources, food waste reduction, single-use plastic policy), and embed specific ESG criteria in your RFP so venues must address them in writing before you shortlist.

Key Sustainability Certifications to Recognise

ISO 20121 — international standard for sustainable event management (most relevant for planners). EU Ecolabel — EU-recognised, strong on energy and waste. Green Key — hospitality-specific, widely recognised in Europe. LEED / BREEAM — building-level certification (good signal, not event-specific). Avoid self-declared badges with no third-party auditing.

Questions to Include in Your Sustainability RFP Section

What percentage of electricity comes from renewable sources? What is your policy on single-use plastics during events? How do you handle food waste from events (composting, food bank donation)? Do you offer a plant-based DDR menu option? Can you provide a post-event carbon footprint report? Is your conference waste separated and recycled?

Practical Sustainability Wins That Cost Nothing Extra

Ditch printed programmes — use QR codes or event apps. Request digital delegate badges (reusable or recycled). Ask for F&B with seasonal local produce (hotels often do this anyway and it reduces cost). Choose venues within walking distance of public transport hubs to reduce transfer emissions. Offset residual emissions via a certified scheme (Gold Standard, Verra).

Embed ESG in Your RFP Scoring

Add sustainability as a weighted criterion (10–15% of total score) in your RFP evaluation. Ask hotels to self-score against your criteria and provide evidence. Hotels with genuine programmes will welcome the question; greenwashers will struggle to answer with specifics.

Frequently Asked Questions

What makes a hotel conference sustainable?
A sustainable hotel conference uses renewable energy, minimises food waste, eliminates single-use plastics, sources F&B locally, and can provide measurable post-event sustainability reporting. Look for third-party certifications like Green Key or ISO 20121.
What is ISO 20121?
ISO 20121 is the international standard for sustainable event management. A hotel or venue with ISO 20121 certification has demonstrated a management system for reducing environmental, social, and economic impacts of events.
Do sustainable hotels charge more for events?
Not necessarily. Many sustainable practices (seasonal menus, LED lighting, digital materials) reduce hotel operating costs. Some certified hotels charge a small premium (5–10%) but offsetting and reporting services are usually included.
How do I add sustainability to my hotel RFP?
Add a dedicated 'Sustainability' section to your RFP with 5–6 specific questions about certifications, energy sources, waste management, and F&B sourcing. Ask venues to respond in writing and score their answers as part of your venue evaluation.
