- Title:
- Historical data on Gekentekende_voertuigen_brandstof
- Requested data:
- Good day. I am a PhD student in Economics and I would like to look into how the introduction of the fijnstoftoeslag in 2020 has impacted the composition of the Dutch vehicle fleet. In particular, I want to investigate whether the fijnstoftoeslag accelerated the scrappage of Diesel vehicles that were subject to paying the fijnstoftoeslag.
I have found the data set "RDWNPACTTAB", which contains yearly data on the composition of the Dutch vehicle fleet from 2010. However, it is unclear whether this data set also contains the relevant fine dust emissions data that are required to identify vehicles that would be subject to the fijnstoftoeslag. Its open data equivalent, "Open Data RDW: Gekentekende_voertuigen", does not contain emissions data but only technical information.
Basically, I would need the historical versions (with past data) of the data sets "Open Data RDW: Gekentekende_voertuigen" (which contains technical information on the current Dutch vehicle fleet) and "Open Data RDW: Gekentekende_voertuigen_brandstof" (which contains emissions data on the current Dutch vehicle fleet).
- Requested format:
- CSV
- Requested period:
- 01/01/2010 - 00:00 till 01/01/2023 - 00:00
- Usage:
- I want to start a research project that investigates whether the introduction of the fijnstoftoeslag accelerated the de-registration of affected Diesel cars from 2020 onwards. For that matter, I would need historical data on the Dutch vehicle fleet, including fine dust emissions data, which is the relevant metric to identify vehicles that are subject to the fijnstoftoeslag.
- Impact:
- The provision of the data would enable me to proceed with my research idea.
What have you already done yourself?
- What is your problem finding data?:
- Data is er maar voldoet niet
- What data is avalible?:
- Current data on emissions of the current Dutch vehicle fleet are available. There is also the data set "Motorvoertuigenpark met kenmerken van voertuigen op kentekenniveau (RDWNPACTTAB)", which contains historical data on the Dutch vehicle fleet since 2010. However, it is unclear whether this latter data set only contains technical vehicle data or whether it additionally encompasses emissions and fine dust emissions data of vehicles, which would be necessary to identify vehicles that are subject to the fijnstoftoeslag.
- Why isnt this data sufficient?:
- This data may not be sufficient because it is not clear whether the historical data set "RDWNPACTTAB" on the Dutch vehicle fleet also contains emissions data.
- What have you already done to find the data?:
- I have looked deeply into the CBS microdata base and went through all kind of descriptive PDFs and metadata, however, it is still not clear to me whether the data that I would need would be readily contained in any of those data sets.
