Regarding secondary data, greenhouse gas emissions from a transport service can be calculated by using default values or modelled data. Default values should be set, and modelled data should be developed and updated in a neutral and objective manner, based on trusted sources and adequate parameters. Databases should not contain default values that lead to the resulting greenhouse gas emissions being structurally understated as compared to known real-world values of comparable services. In such cases, third-party databases should not receive a positive assessment following the technical quality check.
