A typical IELTS Writing Task 2 problem-solution prompt on this topic asks you to analyze the causes of high carbon emissions and propose solutions. According to analysis by English AIdol of 10,000+ essays, 60% of test-takers score Band 6.5 or below on such environmental prompts, often due to vague solutions and repetitive vocabulary. The key to a high score is defining the problem specifically and linking solutions to clear agents of change (governments, industries, individuals).
Prompt (Paraphrased): Many countries are experiencing a serious problem with their carbon footprint. What are the main causes of this issue, and what measures can governments and individuals take to reduce it? Give reasons for your answer and include any relevant examples from your own knowledge or experience.
Task Requirements: You should write at least 250 words. You must identify causes (the problem) and propose solutions. A top-scoring answer will discuss both government and individual actions.
| Band 6.0 Sample | Band 7.0 Sample | Band 8.0 Sample | Band 9.0 Sample | | :--- | :--- | :--- | :--- | | Response: Many countries have a big problem with carbon footprint. The main cause is that people use cars too much. Everyone wants to drive their own car to work or shopping, and this makes a lot of pollution. Another cause is factories. Factories make many things we buy, and they use a lot of energy that comes from coal and oil. This is bad for the environment. <br><br> Governments can solve this problem. They should make better public transport. If buses and trains are cheap and comfortable, people will not use their cars. Also, governments can tell factories to use solar power. Solar power is clean and good. <br><br> Individuals also have a role. People should try to use less electricity at home. They can turn off lights. They can also recycle paper and plastic. If everyone does these small things, the carbon footprint will be lower. This is important for our future. <br><br> (Word count: 168) | Response: The escalating carbon footprint of nations is primarily driven by reliance on fossil fuels for energy and transportation. Many economies still depend on coal and natural gas for electricity generation, which releases substantial CO2. Furthermore, the prevalence of private vehicle ownership, especially in urban areas, contributes significantly to emissions due to petrol and diesel combustion. <br><br> To mitigate this, governments must implement decisive policies. Firstly, they should invest heavily in renewable energy infrastructure, such as wind and solar farms, and provide subsidies to accelerate the transition from fossil fuels. Secondly, urban planning must prioritize sustainable mobility by expanding affordable, efficient mass transit systems and building dedicated cycling lanes to reduce car dependency. <br><br> On an individual level, citizens can adopt a more conscious lifestyle. Choosing public transport over private cars for daily commutes, reducing meat consumption, and minimizing food waste are practical actions that collectively lower carbon emissions. While systemic change is crucial, public participation is equally vital for long-term success. <br><br> (Word count: 178) | Response: The critical issue of soaring national carbon footprints stems from systemic dependencies on carbon-intensive industries and consumption patterns. The primary cause is an energy sector still dominated by fossil fuels, particularly in developing economies striving for rapid industrialization. A secondary, pervasive cause is the culture of conspicuous consumption in affluent societies, which drives demand for manufactured goods, international shipping, and resource extraction—all heavy emitters. <br><br> Governmental intervention is essential for large-scale decarbonization. Legislating a progressive carbon tax would incentivize industries to adopt cleaner technologies, while revenue generated could fund green R&D. Concurrently, national policy must mandate stricter energy efficiency standards for buildings and appliances, a measure proven effective in the European Union. <br><br> Individuals must complement these top-down measures through informed consumer choices. Opting for renewable energy tariffs, embracing a 'circular economy' mindset by repairing and recycling goods, and supporting sustainable brands exert market pressure for change. Education campaigns are key to fostering this environmental citizenship. Ultimately, a synergistic approach combining regulatory force with civic responsibility offers the most viable path to reduction. <br><br> (Word count: 192) | Response: The alarming expansion of the global carbon footprint is a multifaceted problem rooted in economic models, infrastructural legacies, and behavioral norms. Fundamentally, it is an issue of path dependency: national grids and transport systems were built around fossil fuels, creating immense inertia against change. Compounding this is the globalized supply chain, where the carbon cost of production is often exported, obscuring the true environmental impact of consumption in developed nations. <br><br> To dismantle these entrenched systems, governments must pursue a dual strategy of disincentivizing carbon use and actively building alternatives. Implementing a robust carbon pricing mechanism, whether through taxation or a cap-and-trade system, internalizes the environmental cost for polluters. Simultaneously, strategic public investment is required to overhaul energy infrastructure—for example, Denmark's state-backed transition to wind power now supplies over 40% of its electricity. Urban policy must also foster 15-minute cities, where daily needs are accessible without private vehicles. <br><br> Individual agency, while constrained by systemic factors, remains potent through collective action. Citizens can drive demand for green products, divest personal savings from fossil fuel companies, and adopt plant-based diets, which have a markedly lower carbon intensity than meat-heavy ones. However, the most impactful individual act is political: voting for and advocating leaders committed to binding emission targets. Thus, the solution lies not in a single silver bullet but in a concerted, multi-stakeholder alignment of policy, technology, and social norms toward sustainability. <br><br> (Word count: 250) | | Scoring Breakdown: <br> Task Response (5.5): Addresses the prompt but ideas are underdeveloped. Causes (cars, factories) and solutions (public transport, solar, recycling) are mentioned but not expanded. The response is short (168 words). <br> Coherence & Cohesion (6.0): Uses basic paragraphing and simple linkers ('Another cause', 'Also'). The progression is logical but mechanical. <br> Lexical Resource (6.0): Uses a limited range of vocabulary ('big problem', 'bad for the environment', 'small things'). Some repetition. <br> Grammatical Range & Accuracy (6.0): Uses a mix of simple and compound sentences. Several errors ('This is bad for the environment. This is important...'). | Scoring Breakdown: <br> Task Response (7.0): Clearly addresses all parts of the prompt. Presents relevant causes (fossil fuels for energy/transport) and solutions for governments and individuals. Ideas are extended and supported. <br> Coherence & Cohesion (7.0): Logically organizes information into clear paragraphs. Uses a range of cohesive devices ('Furthermore', 'Firstly, Secondly', 'While...'). <br> Lexical Resource (7.0): Uses sufficient range of vocabulary ('escalating', 'mitigate', 'decisive policies', 'sustainable mobility', 'conscious lifestyle').

May have occasional minor errors. | Scoring Breakdown: <br> Task Response (8.0): Sufficiently addresses all parts of the prompt with well-developed, relevant ideas. Explores causes (systemic dependencies, consumption culture) and solutions (carbon tax, efficiency standards, circular economy) in depth. <br> Coherence & Cohesion (8.0): Sequences information and ideas logically. Manages paragraphing skillfully. Cohesive devices are used flexibly and appropriately. <br> Lexical Resource (8.0): Uses a wide range of vocabulary fluently and flexibly ('soaring', 'pervasive', 'conspicuous consumption', 'decarbonization', 'synergistic').
