- GHG Inventory
- A quantified account of all greenhouse gas emissions and removals attributable to an organization, measured in metric tons of CO2-equivalent (tCO2e).
- Scope 1 Emissions
- Direct GHG emissions from sources owned or controlled by the organization, such as on-site combustion, company vehicles, and industrial processes.
- Scope 2 Emissions
- Indirect emissions from the generation of purchased electricity, steam, heat, or cooling consumed by the organization.
- Scope 3 Emissions
- All other indirect emissions in a company's value chain — upstream (suppliers, raw materials) and downstream (product use, end-of-life disposal) — not included in Scope 1 or 2.
- Baseline Year
- The reference year against which all future emissions reductions are measured, typically the most recent year for which complete, verified data is available.
- Carbon Dioxide Equivalent (CO2e)
- A standard unit expressing the warming potential of all greenhouse gases relative to carbon dioxide, allowing different gases to be combined into a single comparable figure.
- Third-Party Verification
- An independent assessment by an accredited auditor confirming that reported emissions data and reduction claims are accurate and consistent with the agreed methodology.
- Science-Based Target (SBT)
- An emissions reduction target aligned with the level of decarbonization required to limit global warming to 1.5°C or well below 2°C above pre-industrial levels, as defined by the Science Based Targets initiative.
- Carbon Offset
- A verified reduction or removal of one metric ton of CO2e achieved outside the organization's boundary, purchased to compensate for emissions the organization has not yet eliminated.
- Remediation Plan
- A documented corrective action plan submitted by a party that has missed an agreed emissions milestone, specifying additional measures and a revised timeline for compliance.
- Net Zero
- A state in which an organization's total GHG emissions are reduced as far as possible and any remaining residual emissions are balanced by permanent carbon removals.
- Materiality Threshold
- The minimum percentage deviation from a reported emissions figure — typically 5–10% — that triggers a restatement obligation or non-compliance notice.
