Events enable the human engagement, collaboration and inspiration we need to achieve the UN Sustainable Development Goals

Sport, business and cultural events bring your companies (or your clients) brand to life and implementing ISO 20121 will enable you to consider sustainability at every decision point whether you are the event owner or an SME in the event supply chain.

What is ISO 20121: 

ISO 20121 offers guidance and best practice to help you manage your event and control its social, economic and environmental impact. ISO 20121’s flexible approach means that it can be used for all types of events, from music festivals to school outings, from business meetings to exhibitions from major sport events to community parties.

The standard has been developed with input from many different stakeholders, including representatives from the event industry, to make it practical and useful. It addresses all stages of an events’ supply chain, and includes monitoring and measuring guidelines. 

Why is ISO 20121 important: 

You can make your event more sustainable, no matter its type or size, with ISO 20121.
Events take a heavy toll on resources, society and the environment, often generating significant waste. In addition to promoting more responsible consumption, this International Standard has been developed to relieve the strain on local infrastructure and utilities, reducing the potential for conflict in communities where events are hosted. 

Who is ISO 20121 for:

If you are involved in the event industry in any way, this standard is for you.
