A practical sustainability certification for events – built for implementation, not paperwork.
Greentime is a sustainability certification used by festivals, sports events and public organizers to turn sustainability requirements into real, measurable action.
The certification combines a digital implementation tool with clear mandatory criteria and structured review – making sustainability work in practice, not just on paper.
What makes Greentime different
Many sustainability frameworks focus on policies, reporting or high-level ambition. Greentime is designed for real events, real teams and real constraints — where sustainability must function alongside tight schedules, limited resources and complex stakeholder environments.
With Greentime, sustainability becomes part of everyday event planning, rather than a parallel or isolated process.
The certification is built around
- Mandatory sustainability requirements that ensure a credible minimum level
- A structured digital tool supporting implementation and follow-up
- Clear responsibility within the event organization
- Documentation, review and continuous improvement over time
Together, this creates clarity, accountability and long-term impact.
Why certify?
Certification is not an end in itself. It is a tool to strengthen both operations and credibility. By certifying by Greentime, you can:
- Strengthen credibility
Certification provides proof of actual achievement, demonstrating that concrete actions have been taken to reach sustainability objectives. -

You can clearly and credibly communicate your sustainability work to audiences, partners and stakeholders. -
Attract customers, sponsors and partners

We are with you on the journey
We know from experience that event organizations often operate under significant time pressure, with sustainability being just one of many responsibilities.
Through the certification process and our ongoing support, we help bring structure and clarity to sustainability work — turning it from an additional burden into something meaningful, manageable and integrated into daily operations.
Many certified events report concrete benefits, such as:
-
Reduced costs related to waste and littering
-
Improved working environments
-
Reduced food waste
-
Clearer roles and decision-making
In practice, this often leads to a better-functioning event overall — not just a more sustainable one.
