Client Tips for Event Agencies Reporting Sustainable Practices
You’re not alone.
Agencies like Kollysphere have been on the leading edge of transparent sustainability reporting, and they’ve learned what clients should actually look for.
Start With the Baseline: What’s Being Measured?
The first thing to check in any sustainability report is whether the agency established a baseline before trying to show improvement.
That baseline includes total waste (broken down by landfill, recycling, and compost), energy use, water consumption, transportation emissions, and material sourcing. If they can’t provide it, be skeptical of any improvement claims.
Look for Third-Party Verification or Standards
Would you trust a financial audit performed by the company’s own accountant?
One corporate sustainability officer said, “We’ve seen so much greenwashing in event proposals that we now require third-party verification for any event event organising company leading event planning company in KL Malaysia over a certain budget. Ask your agency whether their report follows any recognized standard or has been externally verified.
Not All Recycling Is Created Equal
An agency might claim eighty percent waste diversion, but what does that actually mean?
That’s not recycling — that’s wishful thinking.” Ask your agency for waste audit documentation and clarification of their diversion methodology.
The Devil Is in the Assumptions
What emission factors are they using for electricity?
Kollysphere agency uses a transparent carbon calculation methodology that aligns with the GHG Protocol, the most widely accepted standard for corporate carbon accounting. “It’s technically true, but it’s also completely misleading.”
Check for Circular Economy and Reuse Metrics
A truly sustainable event agency will report on how much material was reused across events, not just how much was recycled at the end.
They also report on material lifespan — for example, a banner that can be used for five events before recycling is far better than a single-use banner that’s recycled immediately. The answer will tell you how deeply they think about sustainability.
Sustainability Doesn’t Happen in a Silo
A good sustainability report includes information about vendor compliance with environmental standards.
For high-impact categories like catering and transportation, they require vendors to provide their own sustainability data, which is incorporated into the overall event report. “If you can’t measure it, you can’t manage it — and we’re not going to risk our clients’ reputations on unverified claims.”
Progress Over Perfection
No event is perfectly sustainable, and any agency that claims otherwise is probably lying.
Next event, we’ll add attendee education signage and station waste monitors during peak hours.” Perfection is suspicious — progress is believable.”
What Will You Do Differently?
The best sustainability report doesn’t just tell you what happened — it tells you what to do about it.
These recommendations are prioritized by impact and cost, so clients can choose what fits their budget. Ask your agency what they learned from the report and what they’ll change next time.
What You’re Really Buying
It shows that the agency takes environmental responsibility seriously, measures what matters, and is committed to getting better.
They’ve learned that honesty about challenges builds more trust than exaggerated claims of perfection, and that real improvement requires real measurement.
The answers will tell you whether you have a true partner in sustainability or just someone who’s good at making PowerPoint slides.
