The Internal Market Act (IMA) is a post-Brexit piece of legislation designed to regulate markets within the UK nations. However, it can significantly impact environmental legislation across Scotland, Wales, England, and Northern Ireland.
Scotland’s deposit return scheme was delayed for a third time and watered down, partially due to the implications of the Internal Market Act. This shows the potential for the Act to undermine environmental legislation, and under the IMA a reduction in environmental standards in one UK nation can hinder the rest of the UK in making positive environmental legislation. The Act was passed by a majority in the UK Government, though Scotland, Wales, and Northern Ireland did not consent to its introduction.
This page summarizes what we have discovered and why this is important to anyone interested in improving environmental policy-making in the UK.
