Also this motion is not deciding anything. The parliament is just asking the commission (the EU equivalent to a ministry/government) to publish a study on this and take a next step. Fixing to a specific standard would also not be something done in EU law - laws are meant to be slow-changing, this would be a barrier. You might have a law that specifies that a standard should be set and/or industry bodies ought to agree on a standard to use.
