“We’ve contracted Alex Stathakis for Christchurch Airport’s GHG Inventory support for coming up ten years now. His expert knowledge across airport operations, GHG Protocol/ ISO standards/ ACA programme is second to none. He helps us stay ahead of industry best practice, and level up each year in our own reporting and opportunities for improvement. We would recommend, and have recommended, Alex’s support to any airport with ambitions in the ACA programme or wanting to improve their GHG reporting”.
“Alex delivered a pragmatic and customised GHG reporting tool for Hobart Airport that met with our needs and existing systems. His extensive knowledge of the current National and International standards as well as the Airport Carbon Accreditation Program enabled him to provide actionable feedback that was invaluable in achieving our carbon management goals. I would highly recommend Alex/Conversio to any aeronautical business looking for clear guidance and solutions in an increasingly complex and regulated aspect of ESG.”.
“At Eco Green Group, we’ve been using Conversio’s services to assist us with our carbon neutral certification for 5 years now. Alex has always gone above and beyond to support us in our commitment to sustainability, and his passion for what he does clearly comes through in the service he provides. As a company that provides exceptional service and also supports small businesses like ours with affordable rates, I would have no hesitation in recommending Conversio.”.
“Alex verified Queensland Airport Limited’s ACA Level 4 application for all four of its airports. This included verifying Scope 1, 2 and 3 footprints. Alex completed the work in a timely and rigorous fashion, demonstrating high technical expertise. He always takes the time to explain things and is open to questions, discussion and robust technical debate on the application of the ACA Application Manual and the GHG Protocol. In addition, Alex is engaging and friendly and I enjoy working with him”.
“Senversa engaged Alex to complete a Third Pary Validation for our Climate Active Certification. We had tight timeframes for completion which Alex was able to meet and allowed us to submit our re-certification application on time. He was very knowledgeable on the subject and provided advice above and beyond what was required. I would happily recommend Alex’s services.”
Clear, defensible climate disclosure you can rely on.
