"We will invest EUR7 billion until 2030 to reduce our greenhouse gas emissions to under 29 million tonnes by 2030 and thereby commit to the Science-Based Targets initiative (SBTi)." Total emissions from 2020 seems to range from 27-39 MTCO2e across reports from the company, where scope 3 is measured inconsistently: Deutsche Post DHL changed from a tank-to-wheel to a well-to-wheel calculation approach to estimate its GHG emissions in March 2021. According to the company, this approach led to an increase of its total emissions in 2020 from 27.38 to 33.3 MtCO2e, of which 8.0 MtCO2e are scope 1, 0.2 MtCO2e scope 2 (market-based) and 25.0 MtCO2e scope 3 emissions. A further breakdown of emissions is not yet available. The new estimates reported by Deutsche Post are lower than the sum of 39.10 MtCO2e in the company’s ESG Statbook, so it remains unclear whether all emission sources are included.

Interim targets for 2025 relate to carbon intensity and zero emissions vehicles rather than emissions reductions, but are not set as distinct targets.
