“The team at SustHub delivered SECAD’s ‘Sustainability Training for Food & Drink Businesses’ programme over 2021/2022. Their depth of knowledge, expertise and insight of the SustHub team was invaluable to participating businesses and the training was professional and supportive at all times. Many of the businesses have implemented positive, practical and sustainable changes to their operations as a result of this support.”

SusHub’s have a deep understanding of the subject matter and the developing needs of business, ensuring the Academy’s offering continually evolves to meet these needs.

“I can without hesitation highly recommend SustHub and Clearstream solutions.  I-RES have been working closely with Susthub and Clearstream solutions over the last 18 months to help us evolve and develop our organisations knowledge and skills in ESG and sustainability.

We have found the SustHub team to be very supportive and flexible in helping us meet our ever evolving needs with excellent communication and time dedicated to finding out what I-RES needs in terms of ESG/ Sustainability training. The learning experiences have been carefully designed through effective conversations with employees, and address a broad range of knowledge, expectations and roles.  We are continuing our relationship and looking at meeting further training needs that enables us to achieve our strategy and sustainability impact.”

Our team had the pleasure of attending Clearstream/SustHub ESG masterclass training session in October 2023, and I must say it was nothing short of fantastic. The session’s primary focus on carbon accounting and reporting was incredibly insightful and eye-opening.

What truly set Clearstream and SustHub apart was their engaging and interactive approach to the training. The session wasn’t just a one-way lecture; it was a dynamic and collaborative learning experience. The instructors were not only experts in the field but also excellent communicators, making complex concepts easy to grasp. The interactive ESG topics and discussions encouraged active participation and deepened our understanding of ESG and carbon accounting.

Our team left the masterclass feeling not only well-informed but also inspired to apply the knowledge gained. SustHub’s commitment to educating and empowering their participants shines through in every aspect of their training. I would highly recommend SustHub to anyone looking to enhance their ESG knowledge and skills. It was an great learning experience. Thank you!
