We urge any company who have carbon accounting and reporting needs to engage with Conversio."

"Alex was indeed helpful in our effort to achieve Level 3 Carbon Emission Accreditation. Whilst maintaining his independent as a Verifier, he  offered significant support in ensuring that all our data are accurate and in line with the Carbon Emission framework which makes the whole process an enjoyable and easy one. I would not hesitate to engage him again in our next application."

"Dsquared Consulting engaged Alex to provide an audit of our carbon account for Climate Active Carbon Neutral certification (at that time known as the NCOS). As a small business and our first time going through Carbon Neutral accreditation, we were very appreciative of Alex for providing very thorough guidance through the requirements and expectations for the audit. Alex's professionalism, prompt responses and willingness to help, where appropriate, was essential for us navigating through the process of becoming Carbon Neutral."
