Our data comes from public sources, refreshed daily and dated on the page. We document the method so the numbers can be checked. No black box.
The paid data houses build their products on the same public registries everyone can access, then sell access and proprietary price estimates on top. We use those public sources directly, and we show our working.
The backbone of the project tracker is public carbon registry data, the same source the global vendors start from. Registries publish project details, issuances and retirements openly.
We filter these sources to our 12 covered nations, so the figures reflect the region rather than a global average.
We publish reference benchmarks, not executable quotes. The EU ETS allowance (EUA) is a live compliance price refreshed daily from public market data. The voluntary figures, nature-based removal, avoidance, the Gold Standard premium, blue carbon and durable removal, are benchmark ranges from public market reporting, each dated on the terminal.
Granular over-the-counter voluntary prices are not public, because most voluntary trades are private bilateral deals. Even the paid vendors estimate these. Rather than dress an estimate up as a quote, we label our reference clearly and, over time, are building a transparent Sifr MENA reference from the registry and exchange data we already collect. When that index publishes, its method will sit on this page.
Each tracked project carries its registry, standard and methodology, vintage, developer, status, credit nature (removal, avoidance or reduction) and co-benefits. Announced initiatives are marked as such until they reach a registry. We name public initiatives where they are genuinely associated, for example NEOM, Red Sea Global or the Royal Commission for AlUla, and we never attach an invented transaction to a real name. Figures are indicative for the credit class and region, and we say so.
Soil organic carbon and vegetation data draw on Sentinel-2 and Landsat satellite imagery and published dryland science, aligned to Verra VM0042 and Gold Standard methodology. We are honest about arid soils: they sequester slowly, roughly 0.1 to 0.5 tonnes of carbon per hectare a year on grazing land, so credible measurement matters more than optimistic headlines.
The intelligence feed and the EUA price are refreshed daily by an automated job, with the date shown on the terminal. Schemes, country profiles and the project tracker are reviewed on a rolling basis as the market moves. If we get something wrong, tell us and we will correct it and date the change.
Sifr Collection does not broker credits, rate them for a fee, or run a trading venue. We have no position in any credit, project or scheme on this site. That independence is what makes the data worth trusting.
