Term	Description
BioCCS	The process of capturing biogenic CO₂ at a point-source and securely storing it for over 1,000 years in a geological storage reservoir.
Bioenergy	Renewable energy derived from organic materials, such as plant and animal waste, agricultural crops, and forestry residues, that are converted into heat, electricity, or fuels through processes like combustion, gasification, or fermentation
Biogenic CO₂	CO₂ originating from biomass sources. Its capture and storage leads to net carbon removals, and is eligible for removal carbon credits.
Fossil CO₂	CO₂ originating from fossil fuels. Its capture and storage is not eligible for removal carbon credits.
Fugitive CO₂ emissions	Unintended leaks of CO₂ from equipment (e.g., reactors, pipelines, trucks). Not to be confused with Leakage
Leakage	Displacement of emitting activities from the project scope to areas outside the project scope, resulting in an indirect transfer of GHG emissions rather than the absolute removal of emissions.
Point-source	A localised, identifiable origin of CO₂ emissions from which a concentrated CO₂ stream can be captured.
Retrofit scenario	The baseline scenario for the addition of a carbon capture unit to an existing site.
Greenfield scenario	The baseline scenario for the construction of a new site, where CO2 capture and product or service generation are co-designed.
Biomass fraction	An accounting construct to delineate which fraction of biomass is used for what purpose. baseline vs additional biomass (retrofit) biomass allocated to CO₂ generation vs allocated to bioenergy generation (greenfield)
Biomass category	The qualitative type and source of biomass eligible under this methodology.
Baseline biomass	A biomass fraction of a retrofit scenario, defined as the biomass consumed by the underlying facility as it existed prior to the retrofit.
Additional biomass	A biomass fraction of retrofit scenario, defined as any extra biomass used in addition to the baseline biomass in a retrofit scenario.
Marginal energy crop	A biomass category for energy crops grown on marginal, degraded or contaminated land, or as a cover crop or intermediary crop.
Primary energy crop	A biomass category for energy crops grown as primary culture on agricultural land, if this land has been repeatedly cultivated for energy crops for at least 20 years prior to the start of the project's activity.
Post-crediting monitoring period	Period up until the point at which responsibility for all geological storage sites used by the activity has been transferred to the relevant competent national authorities, in accordance with national regulations
CRCF	The European Commissions Regulation 2024/3012 on establishing a Union certification framework for permanent carbon removals, carbon farming and carbon storage in products, also called Carbon Removal Certification Framework. URL
RED	The European Commissions Directive 2018/2001 on the promotion of use of energy from renewable sources, also called Renewable Energy Directive. URL
Nameplate energy generation capacity	Mrmaximum theoretical (power) output of a facility, determined by the operator and registered with authorities.
Segregated CO₂ stream	A project's CO₂ stream that remains at all times separated from CO₂ streams from other sources.
Non-segregated CO₂ stream	A project's CO₂ stream that gets mixed with one or more CO₂ streams from other sources after capture.
