A gas that contributes to climate change by absorbing and emitting infrared radiation, used in product carbon-footprint calculations.
Greenhouse gas is a gaseous atmospheric constituent that absorbs and emits infrared radiation, making it relevant to climate-change impact assessment. Greenhouse gas data identifies climate-relevant gases such as carbon dioxide, methane, nitrous oxide, and fluorinated gases, and the gas list, quantities, and conversion basis determine how source emissions become CO2-equivalent values.
This page uses ISO 14067 as non-verbatim implementation context for product-carbon work. It explains why greenhouse-gas data matters for CO2-equivalent calculations, but not every air emission is a greenhouse gas and not every emissions dataset is a complete product carbon footprint.

ISO 14067:2018 - Greenhouse gases — Carbon footprint of products
ISO 14067 provides non-verbatim implementation context for greenhouse gas as a climate-relevant atmospheric gas used in product-carbon calculations and CO2-equivalent conversion.
Non-verbatim implementation-context summary only; not a verbatim ISO definition. ISO 14067 is a copyrighted standard, so this page uses it as implementation context rather than republishing the standard text.
Reference: 3.1.2.1
Reviewed public draft page. Aligns with environmental/footprint policy: separates lifecycle boundaries, impact categories, carbon values, gas inputs, durability evidence, post-use events, and composition/circularity controls.
This term originates in ISO 14067:2018 and/or ISO 14044 LCA methodology. It is used in EU product regulation — particularly under the EU Battery Regulation (PEF method for carbon footprint) and ESPR (environmental footprint) — because both regulations require lifecycle-based quantification of environmental impacts. Practitioners applying these regulations should be familiar with these LCA/PEF concepts to correctly scope, conduct, and verify product-level environmental assessments.
Implementation records should capture gas name, quantity, conversion factor, CO2-equivalent result, source process, lifecycle stage, unit, factor version, data-quality note, and link to the product-carbon calculation or emissions evidence file.
Greenhouse gas is the substance-level climate input for product-carbon evidence. The useful record is not just a gas name or quantity; it must link the source, factor, conversion basis, product, lifecycle boundary, and calculation version.
