The relative share (%) of offset credits retired by all twenty companies in 2020–2023, organised into project start years and vintage years. Darker shades indicate a higher relative share. Project start years reflect the first year that an offset project began issuing credits. Vintage years capture the year in which a specific climate action occurred (e.g. a wind turbine generated electricity). Credits sourced from CDM are not shown as this registry does not disclose vintage years. Years after 2016, marked in blue, are illustratively used as a lenient indicator to designate a maximum age limit for project start years and vintage years set by the CORSIA, a governance mechanism for international airlines. This maximum age limit has also been adopted by other credit trading platforms.
