The graph illustrates the amount of nitrogen oxide – a harmful gas – emitted by four types of vehicles: diesel cars, petrol cars, lorries, and buses.

At first glance, diesel cars are the most environmentally friendly. According to statistics, an average car that runs on diesel releases less than 10g/km of nitrogen dioxide, and the number doesn’t rely on speed. Petrol cars also emit more than diesel cars.

In contrast to smaller vehicles, lorries and buses contribute significantly to greenhouse gas emissions, which adversely impact the environment. Lorries typically emit between 25 and 35 grams of carbon dioxide per kilometer, while buses have a slightly higher range, emitting from 25 to 40 grams per kilometer. This considerable output underscores the need for more sustainable transportation solutions.

In conclusion, the environmental impact of lorries and buses is substantial, as they release significantly more nitrogen oxides than other vehicles, such as cars.

Task Response

The report identifies some main features but contains inaccuracies and omissions. The statement about diesel cars being the most environmentally friendly is incorrect based on the data, and the report incorrectly refers to carbon dioxide instead of nitrogen oxide in the third paragraph. To improve, ensure accurate data representation and focus on the key trends and comparisons between all vehicle types.

Coherence & Cohesion

The report is generally well-organized with a clear introduction, body paragraphs, and conclusion. The information is presented in a logical order, making it easy to follow the main points. However, there could be stronger transitions between paragraphs to enhance the flow of ideas. For example, when transitioning from discussing diesel and petrol cars to lorries and buses, a more explicit link could be established to highlight the contrast effectively.

Lexical Resource

The report demonstrates a good range of vocabulary related to environmental impact and vehicle emissions. Terms like 'nitrogen oxide,' 'harmful gas,' 'environmentally friendly,' 'greenhouse gas emissions,' and 'sustainable transportation solutions' are used appropriately. However, there's room to incorporate more precise and varied language to describe the trends and comparisons in the graph. For instance, instead of just saying 'emit more than,' you could use phrases like 'exceed,' 'surpass,' or 'outstrip' to add nuance.

Grammatical Range & Accuracy

The report demonstrates a strong command of grammar with very few errors. The sentence structures are varied and appropriate for the task. Punctuation is also accurate throughout the report. To further enhance the grammatical range, consider incorporating more complex sentence structures, such as using a wider variety of subordinate clauses or participial phrases, where appropriate.
