Environmental Science

Quick Summary

Fieldwork included – Practical investigations in real environments, collecting and analysing ecological data

Cross-disciplinary subject Combines biology, chemistry, geography, and social sciences to tackle environmental issues

Current issues focused – Study climate change, pollution, conservation, and sustainability with real-world relevance

What's it actually like?

IN A NUTSHELL

A-Level Environmental Science explores how natural systems work and how human activity affects them. You'll study ecosystems and biodiversity, pollution and its impacts, climate change science, energy resources, conservation strategies, and environmental management.
You'll learn core science (ecology, atmospheric chemistry, soil science, water systems), investigate real environmental issues, collect and analyse field data, understand environmental policies and regulations, and evaluate solutions to environmental problems.
Assessment includes written exams (essays and data analysis), compulsory fieldwork investigations (collecting environmental data outdoors), and usually coursework or a practical assessment. It's applied science – you're studying real-world problems, not just theory.

Environmental Science is interdisciplinary – you're not just doing biology or chemistry, you're seeing how different sciences connect to understand environmental systems. This appeals to some people but feels less focused to others.

Student Studying

Fieldwork is outdoors in all weather: You'll be outside collecting samples, surveying habitats, testing water – rain or shine. If you strongly dislike outdoor activities, you'll struggle with a significant part of the course.

About the course

Is this for you?

  • A Level Environmental Science explores how natural systems work, how humans affect the environment, and how environmental problems can be managed and solved.


    1. The Living Environment


    You study:
    Ecosystems and biodiversity

    The atmosphere, climate, and weather
    The lithosphere and hydrosphere (rocks, soils, water systems)
    Natural processes such as erosion, flooding, and climate changeThis is assessed in written exams.


    3. Human Impacts and Sustainability


    You study:
    Pollution, waste management, and resource use

    Assessment Structure


    All content is assessed by written exams, with practical and fieldwork skills examined within the papers.

  • Environmental Science is a good choice if you:


    • Are concerned about environmental issues and want to understand them properly

    • Enjoy being outdoors and doing practical fieldwork

    • Like the idea of combining different sciences rather than focusing on just one

    • Are interested in sustainability, conservation, and how humans impact nature

    • Don't mind getting muddy/wet doing field studies

    • Are comfortable with both essay writing and data analysis 

    • Enjoy thinking about solutions to real problems, not just learning abstract concepts


  • Scientific investigation - Designing experiments, collecting data, controlling variables – core practical science skills.

    Data analysis - Interpreting graphs, calculating statistics, evaluating reliability of environmental data.

    Systems thinking - Understanding how different parts of ecosystems and Earth systems interact and affect each other.

    Fieldwork skills - Sampling techniques, using equipment, recording observations, working safely outdoors.

    Problem-solving - Evaluating environmental challenges and assessing potential solutions critically.

    Scientific communication - Writing clear reports, presenting data, explaining complex environmental issues accessibly.

  • It's still proper science: You need solid science skills – understanding chemical processes, interpreting biological data, grasping physical principles. It's not "soft" just because it's applied.


    Maths matters: Calculating concentrations, statistical analysis, interpreting graphs – you need reasonable maths ability (GCSE Higher level comfortable).


    It's broad, not specialized: You'll touch on biology, chemistry, geology, geography, policy – some depth in each, but not as deep as single-science A-Levels. If you want to specialize heavily in one science, choose Biology/Chemistry/Physics instead.


    University requirements vary: Some universities accept Environmental Science for science degrees; others prefer Biology/Chemistry. Check requirements for courses you're interested in – Environmental Science alone might not meet entry for some degrees.


    There's policy and human geography too: It's not purely natural science. You'll study environmental law, sustainability policies, human impacts. If you want only lab-based science, straight sciences suit better.

  • Environmental Science + Geography + Biology = Strong environmental career pathway
    Environmental Science + Chemistry + Biology = Solid science portfolio with environmental focus
    Environmental Science + Geography + Psychology = Understanding environmental behavior and policy

  • Environmental Science rewards understanding connections and applying knowledge. Here's how to succeed:


    Make connections between topics – Link pollution to ecosystem impacts to policy responses. Environmental Science is about seeing the bigger picture, not isolated facts.


    Master data interpretation – Practice reading graphs, spotting trends, evaluating data quality. Much of your assessment involves analysing environmental data critically.


    Take fieldwork seriously – Accurate data collection matters. Learn proper techniques, record carefully, understand why each method works. Fieldwork investigations carry significant marks.


    Follow environmental news – Current examples strengthen essays enormously. Reference real cases, recent studies, ongoing environmental debates.


    Evaluate solutions critically – Don't just describe environmental problems. Assess proposed solutions – what are their advantages, limitations, costs, effectiveness?


    Understand the science properly – Know the chemistry of pollution, the biology of ecosystems, the physics of climate. The science underpins everything – you can't fake it.

  • Environmental graduates can go on to work in:

    • Environmental consultant

    • conservation officer

    • sustainability advisor

    • environmental scientist

    • ecologist

    • waste management

    • renewable energy sector

    • environmental policy

    • climate change analyst

    • parks/wildlife management.

  • Environmental Science is valued by universities. It develops understanding of environmental issues and scientific thinking.


    Environmental Science A-Level opens doors to degrees in:


    • Environmental Science

    • Ecology and Conservation

    • Geography

    • Marine Biology

    • Climate Change Studies

    • Environmental Management

    • Sustainability


    Top tip: Environmental Science bridges multiple sciences - some universities prefer traditional sciences like Biology or Chemistry for competitive courses, so check individual requirements.

  • Ask yourself:


    • Am I genuinely interested in environmental issues and sustainability?

    • Do I enjoy outdoor activities and fieldwork, even in bad weather?

    • Am I comfortable combining different sciences rather than specializing?

    • Do I want to study science that addresses real current problems?

    • Can I handle both essay writing and scientific data analysis?

    • Am I happy with science that includes policy/human geography, not just pure science?

    • Does the idea of working on environmental solutions appeal to me?

Broader application: Understanding environmental issues is increasingly important across all sectors – businesses need sustainability experts, governments need climate advisors, every industry faces environmental regulations.
