United Kingdom

Original text. Later amendments are not shown.

For each manufacturer and each reporting period of the years Y from F12020 to 2030, a CO2 emissions reduction trajectory (ETY) is defined as follows:

ETY=∑sgsharesg×MPWsg×R−ETY×rCO2sg

where:

∑sg

  • is the sum over all vehicle sub-groups;

    • sharesg

  • is the share of new heavy-duty vehicles in the vehicle sub-group sg as determined in point 2.4;

    • MPWsg

  • is the mileage and payload weighting factor as determined in point 2.6;

    • rCO2sg

  • is the reference CO2 emissions as determined in point 3;

    • R-ETY

  • is defined as follows:

    for the reporting periods of the years Y from 2020 to 2025:

    R− ETY=1−rf2025+rf2025×2025−Y∕6

    and, for the reporting periods of the years Y from 2026 to 2030:

    R− ETY=1− rf2030+rf2030− rf2025×2030− Y∕5
    • rf2025and rf2030

  • are the CO2 emissions reduction targets (in %) applicable for the reporting periods of the years 2025 and 2030, respectively.
