Chemical notation of a greenhouse gas or gas group of the Kyoto Protocol basket, used to label emissions in national inventories and emission statistics. Annex A of the Protocol lists CO2, CH4, N2O, HFCs, PFCs and SF6; the Doha Amendment added NF3 for the second commitment period. The regexp accepts plain digits or Unicode subscripts (CO₂) and the singular HFC and PFC. It does not cover single HFC or PFC species or other gases. - Personal data (PII): no - Categories: Environment (protected areas, biodiversity, water, weather, emissions, waste) (environment), Chemistry (chemistry) - Countries: global - Languages: Common to most languages (common) - Classification: categorical ## Detection Regular expression (Python `re`): ``` ^(?:CO[2₂]|CH[4₄]|N[2₂]O|HFCs?|PFCs?|SF[6₆]|NF[3₃])$ ``` ## Examples - `CO2` — Carbon dioxide; Kyoto Protocol, Annex A - `CH₄` — Methane, written with a subscript; Kyoto Protocol, Annex A - `HFCs` — Hydrofluorocarbons; Kyoto Protocol, Annex A - `NF3` — Nitrogen trifluoride; added to Annex A by the Doha Amendment - `NOx` (invalid example) — Nitrogen oxides are an air pollutant, not a Kyoto Protocol gas ## Translations - ru: Парниковый газ Киотского протокола: Химическое обозначение парникового газа или группы газов Киотского протокола — CO2, CH4, N2O, ГФУ, ПФУ, SF6 и NF3 (добавлен Дохинской поправкой). ## Sources - doc: - doc: ## Quality Score 80/100.
