How It Was Delivered
Daiwa Capital Markets Europe Limited (DCME) have worked closely with Carbon Numbers Investments for nearly 10 years now in a partnership driven by the joint belief that by reducing our carbon footprint we can realise savings that can be recycled into further energy saving initiatives. The key learnings are that ‘quick wins’ matter and can make a big difference. Also that in order to make the right decisions you need the available data to be put into a logical format in order to target specific projects and measure the before and after to get a true result.
Carbon Numbers Investments designed and installed an LED lighting programme throughout 5 King William Street that was delivered efficiently with minimal business disruption to the occupants of the building and provided savings in excess of 92,121 kWh per year.
Through the life of our partnership we have reduced energy by over 50% from the original baseline and continue to seek innovative ways to reduce energy.
All systems and processes were delivered in line with ISO 27001, 9001 and 50001 standards

The Results
The programme has delivered measurable, verified outcomes:
“Working with the Carbon Numbers ESOS team made the compliance process straightforward from start to finish. They conducted a thorough energy assessment, identified practical cost-saving opportunities, and guided us through every stage of the ESOS submission. Their expertise and clear communication gave us confidence that we met all regulatory requirements while uncovering valuable energy efficiency improvements. We would highly recommend their services to any organisation preparing for ESOS compliance.”
