Methodology
This calculator implements the BELER Carbon Accounting System (SINTRA 1–2). Every figure is computed from actual consumption quantities — never from money spent. Emissions factors are sourced from published lifecycle assessment databases and are selected by geographic region (GSP) and time period (TSP). All results carry a disclosed uncertainty band per DVTP.
