Additional key figures for Green Transformation
| Anticipated development | 2019 | 2020 | 2020 | |
| Specific greenhouse gas emissions in comparison to 2006 (%) | –34.8 | ~–35 | ~–33 |
| Track kilometers noise remediated in total as of Dec 31 (km) | 1,844 | 2,000 | ~2,000 | |
| Quiet freight cars in Germany as of Dec 31 | 57,644 | 61,000 | ~61,000 | |
Due to the impact of the Covid-19 pandemic, we have adjusted our expectations for specific greenhouse gas emissions in comparison to 2006. The main reason for this is that there were hardly any restrictions to the schedule between March and May 2020, while there were significantly fewer passengers on our trains.
