Why we process the personal data

The Carbon Footprint Calculator produces an estimate of an organisations carbon footprint by using their spend/consumption data for different items and multiplying them by specific carbon emission factors.

The purpose of the calculator is to provide businesses with an easy-to-use tool to allow them to calculate their carbon footprint for the selected financial year, to help highlight areas where carbon emissions can be reduced.

RCT will then advise and signpost the business to assist them in reducing their carbon footprint.

Our lawful basis for processing the personal data

Under the General Data Protection Regulation (GDPR), our lawful basis for processing the personal data to calculate a carbon footprint is;

  • Public Task - Article 6 (e) – processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.

The primary legislation, regulations and guidance that supports this includes, but is not limited to;

  • Climate Change Act 2008
  • The Well-being of Future Generations (Wales) Act 2015
  • Making Rhondda Cynon Taf Carbon Neutral by 2030 – RCT Council Climate Change Strategy

Who or where we get the personal data from

  • The calculator will be made available to any business that want to use it  - both current RCT suppliers and potential future suppliers. Only data input by these businesses is used to calculate the carbon footprint.

Who we share personal data with

We do not share the personal data with any other organisations.

Data Processors

A data processor is a company or organisation that processes personal data on our behalf. Our data processors act only upon our instruction. They cannot do anything with the personal data unless we instruct them to do so. They will not share the personal data with any organisation apart from us or use it for their own purposes. They will hold it securely and retain it for the period we instruct.

The category of data processor we use for the purpose of calculating and storing a carbon footprint is;

  • IT system supplier.

How long we retain the personal data

We retain the personal data contained within carbon footprint records for:

Length of time


3 years

In order to track the efforts made by suppliers (both current and potential) in reducing their carbon footprint. Each carbon footprint result should be at financial year apart.

In keeping with the General Data Protection Regulation storage limitation principle, records are periodically reviewed. Not all personal data is retained. Only personal data that is relevant to the record is retained for the entire retention period.   Information that has no long term or evidential value is routinely destroyed in the normal course of business.
