Carbon Accounting
Neoni® App is a cloud-based carbon accounting platform designed to produce transparent and auditable greenhouse gas emissions inventories by applying financial accounting principles to emissions data. Originating from a Scottish Government innovation challenge won in 2021, the first public iteration of the software (Neoni® Borealis) evolved into Neoni® App, with a beta release available for industry testing. The platform uses a recursive allocation approach aligned with the E-Ledger Method to calculate direct and indirect emissions across complex value chains and supports reporting aligned with major frameworks such as the GHG Protocol, ISO standards, and the Science Based Targets initiative. and PCAF. Neoni® App integrates financial data, engages suppliers for primary emissions inputs, and identifies emissions hotspots to inform decarbonisation strategy. Positioned for organisations seeking methodological rigor and auditability beyond traditional carbon footprinting.
