Overview Icon

Get the relevant scientific skills you’ll need to tackle these complex issues on this diverse and stimulating course. 

Whether out on field trips or doing nanoscale environmental analysis in the lab, you’ll gain the analytical and practical skills to understand, protect and improve our environment. Not only that, but you’ll get to contribute in a practical way to reducing carbon on- and off-campus in our new module, Towards Zero Carbon. 

Over the four years, you’ll gain a strong scientific core in biology, chemistry, physics and maths. This is vital to working as an environmental scientist, but also gives you flexibility when it comes to your career choice. In your third year, you’ll do a nine-month work placement and you also have the chance to study abroad. And of course, throughout the course, you’ll be able to contribute practically to reducing carbon reliance.

As the world is ever more focused on protecting the environment and cutting carbon emissions, there is ongoing and increasing demand for qualified scientists. Graduates from this course typically go on to high-impact careers as research scientists in areas such as environmental protection, and water, air and soil management and conservation.
