IELTS Writing Task 1 question

The graph below shows average carbon dioxide (CO₂) emissions per person in the United Kingdom, Sweden, Italy and Portugal between 1967 and 2007.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Student answer (Band 4.5)

In Portugal the Carbon dioxide emission per person increase from 1 metric ton to 5.5 metric ton its a huge increase and this shows increase in the population in Portugal. here its meet eith sweden population where as sweden carbon dioxide emission falls from 8.5 metric ton to the 5.5 metric ton this is much decrease in the emission on carbon dioxide. Similarly there is increase in CO2 emissions from 4.1 metric ton to 7.9 metric ton in Italy and drops in the emission of carbon dioxide in the UK from 11.4 metrics ton to 8.4 metric ton this whole chart basically shows the CO2 emission in different regions in different era this may be due to any environmental issue or the decrease or increase in the population in that area

Task Achievement / Task Response: Band 4.5

You identify the broad direction of change for all four countries: Portugal and Italy rise, while Sweden and the UK fall overall. However, the response only partially summarises the graph and gives no clear overview of the main comparisons, such as the UK remaining highest or Portugal rising to match Sweden by 2007. Some figures are inaccurate: Italy ends at about 7.6 tonnes, not 7.9, and the UK begins at about 10.8, not 11.4. The claim that Portugal’s rise shows population growth is unsupported; the graph reports emissions per person, not population. The response is also 19 words below the required minimum. Include a concise overview and select accurate key figures to develop the summary.

Coherence and Cohesion: Band 4.0

The response moves through the countries in a broadly understandable order, and linking expressions such as “Similarly” and “whereas” show an attempt to connect comparisons. However, the ideas are packed into one paragraph and one long sequence, so the reader has to work to distinguish the trends and comparisons. The opening focuses on Portugal, but there is no separate overview to establish the main pattern before the details. Some connections are unclear, particularly “here its meet eith sweden population,” which makes the intended comparison difficult to follow. Organise the answer into an overview and a details paragraph, and use clear links such as “By contrast” or “Meanwhile” to show how each country’s trend relates to the others.

Lexical Resource: Band 5.0

You use relevant topic vocabulary, including “carbon dioxide emission,” “metric ton,” “falls,” and “increase,” so the general subject is recognisable. However, the range is limited and several phrases are repetitive or imprecise, especially repeated references to “emission of carbon dioxide.” “Sweden population” is not an appropriate description of the data, which concerns per-person emissions, and “different regions in different era” is vague. There are also spelling and word-form problems, including “eith” and “metrics ton,” which reduce clarity. Aim for accurate, varied terms such as “per-capita emissions,” “rose steadily,” and “declined overall,” while avoiding explanations that the graph does not support.

Grammatical Range and Accuracy: Band 5.0

The response attempts to combine ideas using clauses, for example, “this shows increase in the population in Portugal,” but most sentences rely on simple patterns or become long and difficult to control. Verb forms and agreement are frequently inaccurate: “emission … increase” should be “emissions … increased,” and “here its meet” does not form a clear grammatical clause. Articles and plurals are also inconsistent in phrases such as “the Carbon dioxide emission” and “1 metric ton.” Capitalisation and punctuation are weak, with a lower-case “here” after a full stop and several ideas joined without clear sentence boundaries. Practise accurate past-tense reporting and divide comparisons into shorter, complete sentences.
