Environment vocabulary: the words that lift a common topic.
The environment runs through the whole test, in Task 2, in Part 1 and in Part 3. The ideas are familiar to every examiner; the marks are in precise, topic-specific language. Swap the everyday word for the right collocation and the same point reads a band higher.
Why this matters. Lexical Resource is a quarter of your mark, and on a familiar topic the examiner has heard “pollution is very bad” a thousand times. The lift is not rarer words; it is accurate collocation, greenhouse gas emissions, renewable energy, carbon footprint, sustainable development, used naturally. A common academic phrase used correctly beats a showy word used wrongly, every time.
Four clusters that cover most Environment questions.
You do not need a glossary. You need a handful of accurate collocations in each of these areas, ready to deploy.
Climate & emissions
greenhouse gas emissions · carbon footprint · global warming · fossil fuels
The warming problem and what drives it, the spine of most Task 2 environment questions.
Cutting greenhouse gas emissions is the surest way to slow global warming.
Pollution & waste
air pollution · single-use plastic · landfill · contamination
What we put into the air, water and land, and where the rubbish ends up.
Single-use plastic is a major source of marine pollution.
Conservation & resources
renewable energy · biodiversity · deforestation · natural resources
What we protect and what we use up, the balance the test keeps returning to.
Protecting biodiversity matters as much as switching to renewable energy.
Policy & responsibility
carbon tax · sustainable development · conservation · environmental regulation
What governments and individuals can do, the policy angle Part 3 reaches for.
A carbon tax encourages industry to invest in cleaner technology.
Precision beats rarity
The Lexical Resource trap is reaching for a “big” word and using it wrongly, “the ecosystem is degradating”, “contaminative gases” for ordinary emissions. A common academic collocation used correctly (carbon emissions, renewable energy) scores higher than a rare word used incorrectly. Reach for the precise phrase, not the impressive one.
The same point, from Band 6 to Band 8.
At Band 5
The environment is discussed with very general words (pollution, bad, trees, save), repeated often, with occasional wrong collocations (make pollution). Precise topic vocabulary (emissions, renewable) is absent, and meaning becomes vague when a less familiar idea is attempted.
At Band 6
“Pollution is a very big problem and we should protect the environment for the future.” The idea is fine, but the language is general, “very big problem”, “protect the environment”, and could come from almost any candidate.
At Band 7
“Reducing greenhouse gas emissions is essential, since fossil fuels remain the main driver of global warming.” Topic-specific collocations (greenhouse gas emissions, fossil fuels, global warming) carry real information.
At Band 8+
“Curbing carbon emissions is critical, since it not only mitigates climate change but also accelerates the shift to renewable energy and the green jobs that come with it.” Precise lexis, abstraction (the shift to renewable energy), and a controlled complex sentence.
The upgrade most worth making.
Each swap takes a vague, everyday phrase and replaces it with the collocation an examiner expects on this topic. Use them where they fit naturally, not all at once.
| Instead of… | Use… | For example |
|---|---|---|
| bad air | air pollution | Air pollution in cities harms public health. |
| the earth getting hotter | global warming / climate change | Global warming is accelerating ice melt. |
| using up resources | depleting natural resources | Overconsumption is depleting natural resources. |
| cutting down forests | deforestation | Deforestation destroys vital habitats. |
| clean energy | renewable energy | Renewable energy now rivals fossil fuels on cost. |
| plastic rubbish | single-use plastic | Banning single-use plastic cuts ocean waste. |
| car fumes | vehicle emissions | Vehicle emissions are a leading source of smog. |
| look after nature | conserve biodiversity | National parks help conserve biodiversity. |
Two cautions. Do not carpet-bomb the answer with every term, accuracy and natural fit matter more than density. And keep it formal but not pompous: climate change and global warming are both fine; do not force rare jargon you cannot control.

Ten to drill.
Choose the more precise, topic-appropriate option for each gap. Press Check answers for your score and the reason behind each one. Nothing is sent anywhere.
You can collect topic words. Using the right one, accurately, under timed pressure is the work.
Memorised “big” words used wrongly cost marks; precise collocations used naturally earn them, and the difference is hard to judge in your own writing.
In a lesson I mark your topic vocabulary the way an examiner does, where a collocation is exactly right, where it is forced, and where a plain word would have been stronger. Lessons are £20 for fifty minutes, one to one, in proper British English; the first step is a free 25-minute introduction.
