About Us

As of February 2025, Positive Impact has a community of almost 2,000 global event professionals, over 40 corporate Head of Events, over 40 Corporate Head of Sustainability, over 160 SMEs with a Race to Zero commitment, over 5 memorandums of understanding with United Nations bodies.

For almost 20 years not for profit Positive Impact have been providing engagement, collaboration and education to create a sustainable event industry. You could describe Positive Impact as the ‘critical friend’ of the global event sector.

In 2023 we began to focus on bringing needed innovation to life by supporting two projects:

The Pavilion for People

Technology to make it easier for your event to have a positive Impact

Positive Impact is the only event sector body to be a Race to Zero Accelerator, UN SDG Action mobiliser and to have education certified by the world’s largest and leading CPD accreditation working across all sectors, so our education is accessed by heads of marketing, HR and sustainability.

Our funding comes from everywhere and nowhere, and every penny, cent or yen is used to advance the event sector so every time an event happens the UN Sustainable Development Goals are advanced and events are recognised as ensuring 'participation and inclusion in decision making’ (UN SDG16).

This is a timeline of Positive Impact's journey and the creation of a sustainable event industry. It reflects initiatives from:

  • The United Nations

  • Positive Impact

  • CEO Fiona Pelham

  • Key developments in the creation of a sustainable event industry.
