Cleaned-up and consolidated car fuel consumption and emissions data for years 2000 to 2013. Data is published by the Vehicle Certification Agency (VCA), an Executive Agency of the United Kingdom Department for Transport.
Data is available to download at http://carfueldata.direct.gov.uk/downloads/default.aspx.
It is assumed that the data is released under the UK Open Government License.
For more details about the data, please check the information booklet http://carfueldata.direct.gov.uk/additional/aug2013/VCA-Booklet-text-Aug-2013.pdf.
The original data is published in separate CSV file starting from 2000, but
the format is not consistent across years. Data has been consolidated for
machine using OpenRefine. The script with the tasks
performed on the 2013 CSV files is included in the scripts
folder. Some
example operations performed include:
- Consolidate different field names across different years
- Consolidate measure units for emissions data across different years
- Set proper field types to allow indexing and analysis (eg numeric fields)
- Normalize manufacturer and model descriptions
- Trim excess whitespace
- Fix encoding for special characters
- etc
Note that the resulting dataset does not include all fields in the original data, only those deemed more relevant.
