An image to illustrate the Master of Environmental Science
An integrated masters is an undergraduate degree combining undergraduate and postgraduate study. The Master of Environmental Science (MEnv) takes an interdisciplinary approach to understanding, managing, and protecting the environment. You’ll explore conservation, ecology, ecosystems, environmental management, and renewable energy, while addressing global challenges like climate change, sustainability, and biodiversity loss. The MEnv also covers socio-economic, political, and ethical dimensions. You’ll gain scientific knowledge, technical skills in remote sensing and climate modelling, and transferable skills in communication, project management, and research. By the end of your degree, you'll be equipped to assess environmental issues and propose effective, science-based solutions.
This course is accredited by:
Chartered Institution of Water and Environmental Management (CIWEM) logo.
Institution of Environmental Sciences (IES) logo.
Stages 1–2 of this integrated masters degree are the same as our Diploma of Higher Education in Environmental Science (W47) and Stages 1–2 of our BSc (Honours) Environmental Science (Q52).
This master of environmental science (MEnv) has four stages, each comprising 120 credits.
You’ll study a 60-credit module introducing topical environmental issues and a 60-credit module exploring scientific ideas that underpin the further study of science.

By studying this degree, you’ll:
You’ll be supported by expert tutors, rich materials and field school experiences.
You’ll be awarded a Master of Environmental Science upon successful completion.
Your honours classification (first, upper second, lower second or third class honours) will depend on the grades you gain at Stages 3 and 4.
You'll also have the opportunity to attend a degree ceremony.
If you plan to work or study outside the UK, we recommend checking whether this qualification meets local requirements. Find out more about the international recognition of Open University qualifications.
As a student of The Open University, you should be aware of the content of the qualification-specific regulations below and the academic regulations that are available on our Student Policies and Regulations website.
We regularly review our curriculum to keep it up to date. This means the structure, availability, and content of the course or modules may change. We’ll update this page as soon as possible if there are any changes. If you have already registered for this qualification, we’ll inform you in good time of any upcoming changes where practicable. For more details, see our Academic Regulations or contact us.
You can achieve this integrated masters in as little as three years and have a maximum of 16 years to complete it. Our module-by-module approach gives you the flexibility to complete your qualification at a pace that works best for you.
You can complete this degree in four years by studying at a pace equivalent to full-time. That’s similar to a student at a campus-based university.
You can complete this degree in eight years by studying part-time. That’s roughly half the rate of a student on a full-time course at a campus-based university.
Your last module (S840) ends in September, so you’ll receive your final results in November rather than June/July. You should consider this if you’re planning further study and wish to use your MEnv as an entry qualification.
At the OU, flexibility and support go hand in hand. You’ll be in control of when and where you study, with clear deadlines to guide your progress. Whether you’re balancing work, family or other commitments, our approach helps you fit learning into your life. Students consistently praise the support we provide, and from the very start, you’ll be part of a vibrant OU learning community.
As you progress through your qualification, you’ll have access to a dedicated online study space, expert tutor guidance, optional live tutorials, and a wide range of resources to help you succeed. The sections below outline what you can expect.
Your module website will be a central hub for your learning, giving you easy access to:
Discover how the OU’s module websites, course materials, and support tools help you study online with confidence.
Each module has a dedicated tutor who will guide you through your studies. They’ll provide feedback, help you find resources, mark your assignments and support your learning journey.
For extra support, you can attend optional live tutorials with your tutor. These are usually conducted online, and most are recorded so you can review them later.
See how OU tutors and tutorials help you build confidence, connect with others, and get the support you need to succeed in your studies.
Our assessments reinforce what you’ve learned and show your understanding. Assessment types vary by module and may include:
Throughout your studies, you’ll have access to a wide range of support services and be part of a vibrant learning community. Our subject-specific Student Support Teams can help with general queries and any updates to your OU account. You’ll also benefit from:
Discover the support network and learning tools you'll have access to throughout your studies.
There are no formal entry requirements for this qualification.
If you’ve studied at university level before, you may be able to transfer the academic credit you've been awarded towards an OU qualification. This could save you time and money by reducing the modules you need to study.
It’s not just university study that can be considered; you can also transfer study from a wide range of professional or vocational qualifications, such as HNCs and HNDs.
You should apply to transfer credit before registering, at least four weeks before the registration closing date. We will need to know what you studied, where, and when, and you will need to provide evidence of your previous study.
