IELTS Writing Task 2 question

Some people have decided to reduce the number of times they fly every year or to stop flying altogether.

Do you think the environmental benefits of this development outweigh the disadvantages for individuals and businesses?

Give reasons for your answer and include any relevant examples from your own knowledge or experience.

Student answer (Band 8.5)

Here is the Band 9 version of the essay.

To reach a Band 9, the response elevates lexical density with highly natural collocations, uses sophisticated grammatical structures (such as complex passive voice, participle clauses, and precise hedging), and demonstrates seamless coherence without relying on basic transitional markers.

In recent years, a growing segment of the global population has opted to curtail air travel or abstain from flying entirely, driven by environmental considerations. Although restricting aviation imposes logistical constraints on personal mobility and international business operations, the environmental imperatives of this shift unequivocally outweigh the attendant economic and personal drawbacks.

Admittedly, curbing air travel presents tangible operational hurdles for commercial entities and individuals alike. Transnational enterprises rely heavily on long-distance aviation to foster executive relationships, participate in global trade expos, and oversee foreign operations. A abrupt reduction in business travel risks stalling high-value negotiations and dampening international trade flows. On an individual level, limiting flights inherently restricts cross-cultural engagement and long-distance tourism, while placing a strain on diaspora communities seeking to maintain ties with families abroad. Furthermore, alternative transit modes—such as high-speed rail or maritime travel—remain either geographically unfeasible for transoceanic routes or prohibitively time-consuming within standard leave allocations.

Nevertheless, the ecological benefits of reducing flight frequency are profound and unassailable. Commercial aviation remains one of the most carbon-intensive sectors, discharging massive quantities of carbon dioxide and high-altitude nitrogen oxides directly into the upper atmosphere. Unlike ground transportation, which can be progressively decarbonized through electrification, long-haul aviation remains tethered to fossil fuels due to current limitations in energy density and battery weight. Consequently, individual decisions to forgo discretionary flights or substitute short-haul routes with high-speed rail yield an immediate, measurable reduction in personal carbon footprints.

Moreover, many corporate disruptions can be effectively neutralized through digital substitution. The rapid maturation of high-definition video conferencing, cloud-based collaboration platforms, and virtual workspace tools has demonstrated that physical presence is no longer a prerequisite for commercial success. Transitioning routine corporate travel to virtual formats enables firms to optimize operational overhead while simultaneously curtailing enterprise-level emissions.

In conclusion, while restricting air travel introduces undeniable friction into global commerce and personal leisure, these inconveniences are largely manageable through modern telecommunication frameworks and alternative transit infrastructure. Given the catastrophic risks posed by accelerated climate change, the environmental dividends of reduced aviation far outweigh the temporary inconvenience imposed on individuals and businesses.

AI examiner evaluation

Task Achievement / Task Response — Band 8.5

The response fully addresses all parts of the prompt. You have clearly established a position in the introduction and maintained it consistently throughout the essay. The arguments regarding both the disadvantages (logistical constraints for business and individuals) and the environmental benefits are well-developed and supported with relevant examples, such as the mention of digital substitution and the specific nature of aviation emissions. The ideas are logically extended, and the conclusion effectively synthesizes the main points, confirming that the environmental dividends outweigh the drawbacks. The response is comprehensive, balanced, and demonstrates a sophisticated understanding of the task requirements.

Coherence and Cohesion — Band 8.5

The essay demonstrates excellent logical progression. Each paragraph has a clear central theme, and the transition between the discussion of disadvantages and the subsequent environmental benefits is seamless. You use a sophisticated range of cohesive devices, such as 'Admittedly,' 'Nevertheless,' and 'Consequently,' which are integrated naturally rather than mechanically. The paragraphing is skillful, with each section serving a distinct purpose in the overall argument. The use of referencing is precise, ensuring that the reader can easily follow the flow of ideas from the introduction to the final conclusion without any confusion.

Lexical Resource — Band 8.5

The vocabulary is highly sophisticated and used with great precision. You demonstrate a wide range of natural collocations and academic terminology, such as 'curtail air travel,' 'environmental imperatives,' 'attendant economic drawbacks,' and 'discretionary flights.' The use of 'unassailable' and 'neutralized' shows a high level of lexical control. There are no errors in word choice or collocation, and the language is consistently appropriate for an academic context. The lexical density is high, contributing to a professional and persuasive tone throughout the essay.

Grammatical Range and Accuracy — Band 8.5

The grammatical range is exceptional. You employ a variety of complex structures, including participle clauses ('driven by environmental considerations'), passive voice constructions, and well-structured conditional and concessive sentences. The control over punctuation and sentence structure is flawless, with no errors noted. The use of hedging and precise modifiers adds to the academic quality of the writing. Every sentence is error-free, demonstrating full flexibility and accuracy in the use of English grammar, which is characteristic of the highest band level.
