Testimonial Kaizen
As a data company we believe that accurate and timely data is of vital importance to manage anything. The logical order, guidance and reference material made it easy for our staff to start planning for our transition to a low carbon economy without need for outside consultants.
Testimonial Mourant
Working through the platform across our multiple sites has created ownership, pride, competition, desire for behaviour change, and enhanced team spirit.
Testimonial Cleland and Co
The unforeseen benefit to signing up is the autonomy it’s given our staff. I’ve been surprised by how many people wanted to be actively involved in the Green team, and the skills they are developing as a result. They are learning teamwork, how to enact change projects and the need to weigh up the costs and benefits of their ideas to be able to put them in front of the Board. They’ve come up with some innovative ideas that wouldn’t have featured had it been left to senior management. The bottom up approach is providing our staff with skills that they need to succeed as future leaders.
Testimonial Carey Olsen
ESI has provided us with an evidence-based framework that is transparent and cost-effective. For an organisation like ourselves it's vital to have a solution that allows you to measure your environmental impact with reliable data and empowers people to shift behaviour.
