The Scottish Environment Protection Agency (SEPA) is the principal environmental regulator in Scotland. Its main role is to protect and improve the environment by ensuring that businesses and individuals comply with environmental laws. SEPA monitors air, water, and land quality, helping to manage natural resources sustainably and tackle pollution. In addition to regulation, SEPA also provides guidance and support to communities and businesses on how to reduce their environmental impact. They work on various initiatives, such as promoting renewable energy and enhancing biodiversity, to create a healthier and more sustainable environment for future generations.
