GHG123

Core Features

GHG123 is a climate accounting platform built explicitly around the Greenhouse Gas Protocol. Its key capabilities include:

• Scope-structured climate accounting - Emissions are organised by GHG Protocol scopes, with reports and dashboards that distinguish direct (Scope 1), purchased energy (Scope 2) and value-chain emissions (Scope 3) across categories such as fuel, electricity, transport, travel, waste and purchased materials.

• Activity and spend-based data capture - Users record operational quantities (for example fuel and electricity consumption) in structured forms, attach source documentation, and can also register spend-based data where physical quantities are not yet available,

• Emission-factor library and methods - The factor library is updated annually and, in the Enterprise tier, can be extended with organisation-specific factors and EPD data; standard factors in GHG123-based reports are primarily taken from sources such as DEFRA, NVE, IEA and AIB, with separate handling of biogenic emissions.

• Dashboards and climate reports - Status dashboards show annual trends for emissions, energy, materials and waste, while detailed climate reports present Scope 1–3 results using both location-based and market-based methods.

• Audit support and traceability - Files such as electricity bills can be attached as documentation; all changes are timestamped by user, approvals can lock data, and change logs along with raw-data reports provide visibility over every underlying transaction for internal control and external assurance.

• Scaling, integrations and reporting standards - Plus and Enterprise configurations support multiple organisational levels, role-based access, Excel imports/exports and REST API connections to other systems, while GHG123 outputs data and reports that can be used for major reporting frameworks.

Closing Insights

Emisoft has been developing environmental accounting software since 1992 and positions GHG123 as the climate-accounting part of a broader suite for environmental reporting and sustainability services. Over time, the company has specialised in translating regulatory and framework requirements into configurable software, and in 2023 it became part of Aider, a Norwegian advisory group that combines financial reporting and sustainability consulting. This acquisition allows GHG123 to sit alongside services for CSRD and VSME reporting, SBTi-aligned target setting and climate-accounting courses, so that users can connect their software setup with broader governance and strategy work.

The platform is used across sectors and sizes, with referenced customers including Equinor, Norsk Hydro, Lerøy Seafood Group, and the Serbian Environmental Protection Agency. Published climate reports from individual companies also identify GHG123 as the underlying system. Recent releases have added features such as enhanced GHG dashboards, raw-data reports for detailed QA, expanded support for biogenic emissions and dedicated VSME reporting formats, reflecting a focus on auditability and evolving European disclosure needs. Pricing is modular, depending on functionality, integrations, number of entities and advisory support, which leaves room for smaller users to start with simpler setups while larger organisations extend the system via APIs and custom factors.
