Hi, I'm Erdinç
GHG inventory specialist with 10+ years across ministries, industrial facilities, and academic research. I got tired of rebuilding the same Excel models — so I built a proper tool.

How CarbonTiers happened
I've spent the last decade doing GHG inventories and climate modelling — for ministries, industrial facilities, research projects, and academic work. IPCC 2006 guidelines, national inventories, corporate footprints, scenario analysis. The usual mix of spreadsheets that grow too big, emission factor PDFs that never agree with each other, and verifiers asking the same questions every year.
At some point I got tired of rebuilding the same Excel models from scratch for every project. So I started writing a proper tool in Python. One sector became five. One client request became CBAM, CSRD, CRF export, FOD waste model, AR4/5/6 switching.
Most carbon accounting platforms I looked at are either expensive enterprise SaaS that hides methodology behind a sales call, or spreadsheet templates with outdated factors and no audit trail. There was no middle option — a tool that a serious practitioner can trust, a student can afford, and a verifier can follow from activity data to tCO₂e.
So I'm building that middle option. CarbonTiers.
What CarbonTiers is today
- All 5 IPCC 2006 sectors — Tier 1/2/3 where data supports it
- Corporate footprint tool: Scope 1, 2, 3 — ISO 14064-1:2018 structure
- Dual Scope 2 reporting (location-based + market-based)
- CBAM cost simulation and CRF table export
- AR4, AR5, AR6 GWP switching per calculation
- A free plan that actually does real work — not a trial gate
What it isn't
It's not a consulting firm. It's not an audited enterprise suite. It's one person writing code and methodology carefully, shipping often, and talking to users directly. If you need a 40-person sustainability agency, I'll happily point you to one.
Who I work with
Students
