About Climatise
We got tired of watching companies burn money on spreadsheets and manual reporting. So we built the engine that does the heavy lifting.
Climatise is a carbon accounting platform built by people who've done the reporting themselves. We handle the data collection, the calculations, the methodology, and the compliance frameworks — so sustainability teams can focus on the work that actually moves the needle.
Our Story
Born from frustration. Built with conviction.
Every organisation we worked with had the same problem. The data to produce a carbon report already existed — buried in energy bills, fuel receipts, invoices, and supplier records. But instead of software that could read it, companies were paying consultants five figures to manually wrangle spreadsheets. The output? A static PDF, delivered months late, outdated on arrival.
"The entire carbon reporting industry was built on manual labour disguised as expertise. We decided to automate the labour and democratise the expertise."
Climatise was founded in London in 2021. We started with SECR — the regulation most UK companies actually need — and built outward. Scope 3 supplier engagement. AI-powered data extraction. CSRD and ISSB modules. White-label infrastructure for consultancies who want to scale without hiring.
Today we work with everyone from 10-person charities to Premier League football clubs to multinational manufacturers. One platform. Every scope. Every framework. No consultants required.

The Team
The people behind the platform
Sustainability practitioners, engineers, and operators who've lived the problem we're solving. No one here learned carbon accounting from a textbook.
Lennon Harding-Wade
CEO & Founder
Spent years watching organisations haemorrhage money on consultants who delivered PDFs nobody read. Built Climatise to kill the spreadsheet-and-guesswork era of carbon reporting for good. Background in technology transformation and environmental consulting.
Kirill Marketin
CTO
Treats carbon data with the same rigour as financial data — because it should be. Architects the platform that turns messy invoices, bills, and receipts into audit-ready emissions numbers. Previously built data infrastructure for high-volume financial systems.
Ollie Ford
Sustainability Lead
The person who makes sure every number is defensible. Leads methodology, emission factor updates, and regulatory alignment across SECR, CSRD, ISSB, and ESOS. The team's bridge between policy and product.
Rebecca Scholl
Sustainability Analyst
Gets into the weeds of client data so they don't have to. Runs calculations, validates outputs, and ensures every report stands up to scrutiny. The reason our clients sleep well before audit season.
Ben Wakefield
Partnerships Lead
Builds the relationships that scale Climatise beyond direct sales. Works with sustainability consultancies, energy brokers, and member bodies who want to white-label the platform under their own brand.
Daisy Sokerova
Customer Success Lead
Owns the client experience from onboarding to annual report delivery. Turns first-time users into self-sufficient carbon reporters. The voice clients hear most — and the one they trust.
Plus a growing engineering and product team building the infrastructure for what comes next.
What We Believe
Principles, not platitudes
Accuracy is non-negotiable
GHG Protocol methodology. DEFRA emission factors. Full audit trails on every calculation. We don't estimate when we can measure, and we never hide our working. If it's not defensible, it doesn't ship.
Complexity is our problem, not yours
Carbon accounting is genuinely hard. Scope 3 supply chains, location vs. market-based methods, CSRD double materiality — we absorb that complexity so our clients get clarity.
Outcomes over output
We don't count features shipped. We count reports filed on time, emissions actually reduced, and hours given back to sustainability teams. That's the scoreboard.
Where We're Going
Carbon reporting should be as routine as financial reporting. We're building the infrastructure to make that happen.
Right now, most organisations treat carbon accounting as a once-a-year compliance exercise — painful, expensive, and disconnected from how they actually run. We're building toward a world where emissions data flows as naturally as revenue data. Where every procurement decision, every energy contract, every supplier onboarding has carbon baked in.
The platform already handles measurement, reporting, and reduction planning across every scope and every major framework. What comes next is the connective tissue: real-time data pipelines, embedded carbon intelligence in business systems, and an ecosystem where consultancies, member bodies, and enterprises all operate on the same infrastructure.
