Apply To Be a Speaker in 2025

Founded in 2015, The Big Sustainability Expo is dedicated to aiding organisations in their sustainability, environmental management, and corporate social responsibility (CSR) efforts. Our comprehensive and inclusive exhibition floor is curated to present the most effective advice and solutions currently available in the market, featuring a broad array of products, services, technologies, innovations, and expertise from leading associations, institutes, and media, as well as showcasing impactful projects.

Enhancing the Experience

The Expo is enriched by a keynote speaker theatre and a series of workshops, meticulously designed to complement the exhibition floor. These elements aim to highlight the significant achievements of organisations in sustainability, providing attendees with valuable insights and inspiration. Additionally, our programming keeps delegates informed about the latest changes in legislation and policy.

Submission Guidelines for 2025

We are inviting submissions that include:

  • Projects that offer relevant and achievable insights for our delegates, aiming to inspire and educate.
  • Updates on current legislation and notifications of new legislation.
  • Updates on current policies and notifications of new policies.
  • Contributions from industry-leading associations, institutes, or governing bodies on topical updates.
 

How to Apply

If you have worked on a notable project, have updates on legislation or policy, or represent an organisation with relevant insights to share, we encourage you to apply for a slot in our keynote speaker theatre. Please email your details and a summary of your topic to info@southernsustainability.co.uk.

Important Considerations:

No Sales Pitches: Please note that the keynote speaker theatre is not a platform for sales presentations.

Focus on Feasible Projects: While we are keen to explore the vast research, development, and projects supporting climate change initiatives nationwide or globally, our current resources limit our capacity to cover these comprehensively. If you’re interested in presenting such content on our behalf, please contact us first at info@southernsustainability.co.uk to discuss possibilities.
