Built in Lagos

We're building from Lagos — the commercial capital of the continent, where the pressure to disclose is arriving fastest.

CarbonLenx Technologies Ltd. is a 5-person company building the carbon accounting infrastructure that West African industrial companies will be measured by, starting with the SEC Climate Risk Disclosure Guidelines and the CSRD-equivalent regimes that follow.

Origin

11 weeks. 200 suppliers. 140 marked "data unavailable."

In February 2024, Olumide was completing a Scope 3 assessment for a Lagos FMCG conglomerate. His team spent 11 weeks chasing supplier data across 200 vendors. 140 of them never responded. For those 140, the final report said: "Data unavailable — estimated using industry average."

The company's auditors accepted it. The SEC would not, once the new guidelines took full effect.

Olumide called Amara, who had been building an imputation model for climate data gaps as a side project. "I need that model," he said, "but I need it to explain itself to a CFO."

CarbonLenx was incorporated seven months later.

Team

Three co-founders. Two early hires. Five total.

Olumide Adeyemi

CEO & Co-founder

6 years as a sustainability consultant at PwC Nigeria (Lagos). MSc Environmental Management, University of Ibadan. Led Scope 3 assessments for three publicly listed Nigerian companies before leaving in 2023 to build a more accessible solution.

“I've sat in rooms where a CFO was told their Scope 3 footprint was 'unknown — data unavailable.' That answer is increasingly unacceptable to regulators. We remove that excuse.”

Amara Diallo

CTO & Co-founder

MSc Data Science, Imperial College London (2021). Originally from Sierra Leone, moved to Lagos in 2022 to work at a climate fintech startup. Deep expertise in time-series data, AI imputation, and emissions factor databases.

“The hardest part of carbon accounting is not the calculation — it’s the missing data. We treat imputation as a first-class product decision, not an afterthought.”

Temitayo Fadahunsi

Head of Sustainability & Co-founder

PhD candidate (Environmental Science), University of Lagos. 4 years as a NESREA-certified environmental consultant. Built Nigeria's first open-access industrial emissions factor database (2023, published with LASU).

“Every estimate we make has a citation. If we can't cite it, we won't use it. That's what makes our output stand up in a regulatory review.”

Emeka Nwosu

Lead Engineer

BSc Computer Engineering, University of Lagos. 3 years full-stack. Joined November 2024 as the company's first engineering hire.

Values

What we won't compromise on.

Uncertainty is data

We show confidence intervals on every estimate. A precise guess without error bars is a false comfort. Our customers' auditors deserve transparency.

African emissions factors matter

Nigerian grid emission factors, West African fuel supply chain intensities, and local waste treatment profiles differ from DEFRA defaults. We use the right numbers for the right context.

Sustainability teams shouldn’t need data scientists

If a Head of Sustainability cannot run a Scope 3 calculation without calling IT, the tool has failed.
