If you don’t know which Extended Essay subject to choose, think about Environmental Systems and Societies. It’s an ideal blend of science and humanities, because you can analyze the environmental issues through quantitative data alongside the impact of human decisions.
According to IB criteria, ESS is an interdisciplinary subject, which means it combines the best aspects of scientific research and social impact. Before you start, though, consider this: Do you enjoy combining statistics with critical discussion? If you said yes, ESS might be the right place for you. But as an IB tutor, I know it’s not always easy.
So, this piece will explain what the ESS Extended Essay subject is about, who should choose it, and how hard it is.
What Is the Environmental Systems and Societies Extended Essay Subject?
Because you must balance environmental and social sciences, the Environmental Systems and Societies subject is distinctive. You are not restricted to laboratory tests or geographic mapping, in contrast to an Extended Essay in Biology or Geography. ESS, on the other hand, makes it more flexible but still academically difficult by allowing you to mix several approaches.
According to IB standards, ESS is concerned with human-environment connections, sustainability, and the influence of society on natural systems. This, in my opinion, makes it very relevant because practically every policy choice takes into account the environment.
Let’s now discuss the main fields of research related to this subject. Students often concentrate on three areas while choosing ESS:
- Human-environment relationships – for example, how urbanization affects biodiversity.
- Sustainability and resource use – such as renewable energy policies or water scarcity management.
- Scientific and social evidence – you must combine experiments, surveys, and policy analysis in one essay.
As an IB writer and tutor, I can say that Environmental Systems and Societies is a subject that changes over time. You can look at real-life natural processes, think about how they affect people, and gain a well-rounded view.
Oh, and what makes ESS especially convenient is that it counts for both Group 3 (Individuals and Societies) and Group 4 (Sciences). So, you can use it as either one (or even as both), giving you a lot more flexibility when choosing your subjects.
Who Should Select Environmental Systems and Societies for an Extended Essay?
You may want to jump into the IB ESS for the Extended Essay because it sounds current or “green,” but not everyone will like it the same way. I can tell you precisely what kind of student is most likely to do well in this subject since I’ve been there.
☑️ Students who enjoy both Science and Humanities.
ESS is an excellent choice for students who enjoy both conducting experiments and debating them in class.
From what I’ve seen, it works best for students who don’t want to be limited to either science or social science, but would rather mix the two.
☑️ Those interested in real-world environmental issues.
In line with IB standards, ESS connects theory and practice. It means that students who want to write an Extended Essay about something useful, like climate change, water scarcity, or waste management, will enjoy it.
In my experience, students are more inspired to write when they choose a topic relevant to their community.
☑️ Learners with critical and reflective thinking skills.
The IB puts more weight on analysis than explanation, and ESS is no different. This subject is suitable for students who can think critically, question their beliefs, and evaluate answers.
For instance, you won’t just need to show recycling numbers; you’ll also need to look into how well those recycling programs really work.
☑️ Students planning future studies in Sustainability or Geography.
Many students who choose ESS are already considering careers in geography, environmental science, or policy. So, writing an essay on this subject might help your college applications by demonstrating that you have a defined academic goal.
Is the Environmental Systems and Societies Extended Essay Hard?
The answer, in my opinion, relies on how you look at it. As with any IB subject, Environmental Systems and Societies isn’t always harder than others, but it does have its difficulties.
Doing well in ESS requires picking the right topic, planning well, and finding a good mix between science and social points of view.
Why It Can Feel Challenging?
In contrast to essays in Biology or History, the ESS requires compliance with the criteria of both Group 3 and Group 4. You will need to show that you can analyze things well and make sure that your study focuses on environmental systems and social effects. Many students naturally lean to one side, which can make this balance hard.
For instance, some go into it with good lab skills but find it hard to talk about how their results affect society. Other students are great at writing essays on Geography or IB Economics, but they find it hard to work with science facts.
The real task in ESS is to show that you can write an essay that makes sense from all of these points of view.
Don’t let the stress of the IB curriculum hold you back.

Common Difficulties Students Face
I’ve found over the years that students often have the same problems when they are writing their ESS essay:
- Choosing a research question that’s too broad (e.g., “How does climate change affect biodiversity?”).
- Many students rush to gather surveys, statistics, or samples without deciding how they’ll interpret them.
- Writing essays that are heavy on description but light on evaluation. You must evaluate what those numbers mean and why they matter.
- Forgetting to link their findings back to the ESS syllabus.
If you choose this subject, keep in mind that the examiner wants to see a clear link to the course outline, not just an interesting essay about the environment.
Why It’s Still Manageable?
Still, I always tell my students that the IB ESS Extended Essay subject is not difficult. Often, it’s easier to get to than most people think, because you are freer to choose how to gather and show data than a pure Science EE.
As an example, surveys, case studies, policy reviews, and secondary studies are all good places to get data. In other words, you don’t always need a lab or expensive tools to do your work. Often, you can use resources in your neighborhood.
Another reason it seems doable is that the IB ESS topics often have clear ties to real life. It feels important to look into things like the air quality in your neighborhood or how the recycling rules in your area really work.
How to Write an Environmental Systems and Societies Extended Essay?
Start by coming up with a clear research question. From what I’ve seen, your work will be better if you make your question narrower and detailed.
You could ask, “How has the use of fertilizer changed the amount of nitrate in the Thames River over the last five years?” instead of “How does pollution affect water?” That change is very important.
When you have a clear question, the next step is to plan how you will answer it. Find a mix between the science and social aspects of ESS. That means you’ll need facts, but you’ll also need to figure out what it all means in the bigger picture.
Here is a quick list of the things I generally recommend students:
| STEP | WHAT TO DO | WHY IT MATTERS |
|---|---|---|
| 1. Narrow the Question | Focus on a specific issue, location, or time frame | Keeps the essay manageable and analytical |
| 2. Plan Data Collection | Decide on surveys, case studies, or experiments | Ensures evidence supports your argument |
| 3. Balance Perspectives | Include both environmental and social analysis | Meets IB’s interdisciplinary requirement |
| 4. Use Visuals | You must add graphs, tables, and maps | Makes data clear and persuasive |
| 5. Link Back to Syllabus | Connect findings to ESS themes | Shows relevance to the subject framework |
By the way, students write the best when they do more than just list facts; they also think about how important those facts are. If you ask yourself “So what?” over and over again while you’re writing, your essay will meet IB criteria.
Should You Choose the IB ES&S Extended Essay Subject?
Yes, if you’re the type of student who enjoys making connections between science and everyday life and solving real-world problems. The Environmental Systems and Societies is an interesting subject for your Extended Essay, but it requires constant work, careful planning, and a real interest.
From what I’ve seen, the best students for this subject are those who care about the environment and want to know how choices made by people affect it.
If you’re still not sure, ask yourself: Will I enjoy studying sustainability, environments, and how people affect them for weeks on end? If the answer is yes, ESS is likely the best choice.
