About Di Marco Carbon
Di Marco Carbon is an independent carbon consultancy founded in 2026 by Seb Di Marco, a senior sustainability specialist with nearly a decade of experience delivering Whole Life Carbon Assessments, embodied carbon analysis, and planning-focused sustainability strategy across the UK.
The consultancy was created to address a growing need in the built environment: clear, proportionate, technically robust carbon advice that genuinely supports design and planning decisions.
Where many sustainability services have become overly complex or process-driven, Di Marco Carbon focuses on clarity, collaboration, and practical outcomes. The aim is simple - to help clients and design teams make informed, confident decisions that reduce carbon without unnecessary modelling or noise.
About Seb
I'm a carbon and sustainability consultant with nearly a decade of experience working across the built environment.
Before founding Di Marco Carbon, I spent more than seven years at Scotch Partners, progressing from Graduate Consultant to Sustainability Lead. During that time, I helped develop the sustainability team, establish the whole-life carbon service offering and deliver projects across a range of sectors including residential, commercial, education, laboratory and mixed-use developments.
Alongside project delivery, I was responsible for technical review, team development, resourcing, fee proposals and business development, working closely with colleagues, clients and design teams throughout the project lifecycle.
Following a career break travelling through South America, I established Di Marco Carbon to provide independent carbon and sustainability advice that is practical, proportionate and closely aligned with project objectives.
