“This is by far the most useful and practical course I have been on and has been the deciding factor in our actual implementation of a business carbon assessment. This is because it has given us the correct details on how to actually go about doing the calculation, rather than just why it is important. We now have the knowledge in our company to continue with this work and improve our performance.”
Maggie FennellR&D Environment and Education Manager
“Tunley Engineering were very efficient from start to finish of our project. For our team, it was very new and untouched territory going into the sustainable, carbon neutral world but our engineers were very patient at explaining the different scopes and what was required from us to reach our sustainable goal. They are stuck to our timelines so we were able to show off the hard work we had put in during our awards presentation, the day after we had our final meeting. As a company we will be doing more projects under carbon neutral banner so would be willing to use Tunley again to make this happen.”

“It w an absolute pleasure to work with Tunley right from the quotation stage to the final presentation. Everything was explained perfectly and all questions answered.”
Rachel MarshallPurchasing Manager
“At Sound United, one of our core values is that 'Our Obligation is Bigger than Us'. When implementing ESG, we needed to understand our baseline for carbon footprint in order to understand how we could reduce our impact on the environment. Tunley's knowledgeable team of professionals knew what we were looking to do, and worked quickly with our global team to gather and analyse our data. Throughout the process, they were easy to work with and on time on their delivery schedule. I highly recommended Tunley's service.”
Leeanne SchererSR. Director of Global Service Operations
“Tunley Engineering has been great support through our carbon assessments. Torill completed an embodied carbon report on one of our products, we used the embodied carbon report and submitted to MAKE UK sustainability regional awards and won for our region. Great to be working with Tunley and the team and look forward to reaching our goal of net zero which I know we can with the support and expertise of the team.”
Scott CommonsHSQE Manager
“The COVID-19 pandemic has deomnstrated how the unimaginable can change the world overnight. Human-made climate change has the same potential to impact our world and requires the right decisions and urgent action now. Optima Products Ltd has committed to achieving net zero GHG emissions in its own operations by 2035, as a manufacturer this will necessitate significant changes. We hve therefore engaged with Tunley Engineering to partner us in delivering this commitment.”
Christian MabeyManaging Director
“I'm very grateful to Tunley Engineering for their professional and thorough approach to our business and product assessment. We brought some complicated and novel requirements and they tackled these with enthusiasm, including tackling novel research. I would highly recommend them to anyone requiring a carbon assessment.”
