COP31 is in Antalya - Turkiye. I built Turkish companies a free compliance radar that never sees their data

COP31 opens in Antalya on November 9, and for Turkish companies the timing is not abstract. Türkiye's first Climate Law took effect in July 2025, and the regulation for its national emissions trading system came into force this August, starting with a pilot phase for large emitters. Companies above set size thresholds report under TSRS, the Turkish sustainability reporting standards. And since January, EU importers of steel, aluminium, cement and fertilisers have been in CBAM's definitive phase, which means Turkish exporters of those goods are being asked for verified emissions data, with the first certificate purchases due in February 2027.

Keeping track of where a company stands across all of this is hard. So I built COP31 Uyum Radarı ("compliance radar"): a free, browser-based self-assessment that maps a company's readiness across Türkiye ETS, TSRS, EU CBAM, CSRD and the main voluntary frameworks, in Turkish and English.

The design decision I'd like your take on:

There is no signup, no backend and no data collection. It's a single HTML file. Everything a company enters stays on their own device.

I originally planned an anonymous benchmarking pool, so companies could see how they compare to their sector. I dropped it. Compliance data is exactly the kind of information companies don't want leaving the building, and I decided that "we never see your data" was worth more than the benchmark. The cost is real: no comparison feature, and no data to learn from.

Some context: HBR Türkiye interviewed me about sustainability measurement and the tool in September. It's free under CC BY-NC 4.0, and the source is on GitHub.

My question for the room: for a tool that asks for sensitive company data, is refusing to collect it a weakness, or the best selling point you have? Has anyone here made the same trade-off, and did you regret it?
