The intention is to cap these emissions at the already low levels being achieved. The fleet average GHG emission value takes into account emissions of carbon monoxide (CO) and hydrocarbons (HC). This ensures that carbon-containing exhaust emissions that ultimately contribute to the formation of CO2 a...

The amendments to the CO2 emissions targets follow the publication by the European Commission, at the end of 2020, of the 2030 Climate Target Plan; this sets a target for 2030 of 55% Greenhouse Gas emissions reduction, compared to 1990. The European Union also has a target of achieving carbon neutrality by 2050. The European Commission identified that the implementation of this strategy requires a revision of the original post-2025 l...
