Volunteering offers many of the same social benefits, with the added bonus of helping others and developing useful skills to put on your CV. Plus, students are in a unique position to help, suggests Tom Fox. "They can take their enthusiasm and excitement for opportunities and share their passions, subject knowledge and experience with people." The idea of giving up time for nothing might seem impractical at first, especially once the pressures of study and coursework or exams begin to mount up. However, Michelle Wright, CEO of charity support organization Cause4, suggests seeing volunteering as a two-way street. "I think it is fine for undergraduates to approach volunteering as a symbiotic relationship where doing good is just one part of the motivation for reaching personal and professional goals."
Katerina Rudiger, head of skills and policy campaigns at the Chartered Institute of Personnel and Development (CIPD), says: "Volunteering can be a valuable way of gaining that experience, as well as building confidence, broadening your horizons, becoming a better team player and developing those all- important 'employability skills' such as communication and decision making." Amanda Haig, graduate HR manager, agrees that volunteering can help your employment prospects. "Volunteering can demonstrate positive personality traits and skill sets, such as proactivity, and teamwork," she says.
A positive side-effect of volunteering is improving your time at university by getting involved in the local community. Leaving the student bubble can make your time as an undergraduate much more varied. At Bath Spa University, more than 1,000 students volunteered over the past year, doing everything from working on local environmental projects to helping in schools or assisting the elderly. ”Quite often there can be a divide between students and permanent residents," says students' union president Amy Dawson, "but if students invest a little time now, they will be giving something back to the local community and will reap the benefits in the future."
“You might also find that volunteering helps your studies if you choose the right program. At Lancaster, volunteering is linked into academic modules in some cases", explains Fox. "This has multiple wins. Students get to apply their learning in the classroom and share their interests with children in local schools or community organizations, while schools gain skilled students with a passion for a subject that enthuses their pupils."

Read the passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

We seem to be entering a boom era for greenwashing - the tactic of covering routine pollution in eco-friendly language. [I] Picture running a high-emitting corporation: meaningful decarbonisation would demand painful negotiations, huge capital outlays, and a full redesign of the business model. Hiring an expert agency to splash "carbon- neutral" or "net-zero" across products is far easier, buying time while emissions remain untouched.

Consumers meet this sleight of hand everywhere. Airlines sell "carbon-neutral" flights, filling stations boast about "net-zero" fuel, and breakfast bacon is re-labelled as planet-safe. Advertising spin is old, yet today it is manipulated to conceal ongoing environmental damage. Social media influencers and glossy sustainability reports amplify these claims, broadcasting the narrative far beyond traditional marketing channels.

The term greenwashing emerged in the 1980s, an era of oil spills and growing climate science, but the practice has exploded only recently. [II] Intensifying public anxiety over global heating and ecosystem collapse has placed companies under sharp scrutiny; many boards therefore choose eye-catching PR over the tougher route of restructuring supply chains, energy sources, and product lines. Regulators on both sides of the Atlantic are struggling to police false eco-claims, yet enforcement still lags behind corporate ingenuity. Investors, eager to protect short-term returns, frequently applaud these surface-level initiatives, reinforcing the cycle. [III] No sector illustrates the issue better than oil and gas. Having realised that denying climate science now backfires, the industry has swapped denial for "green" paint. Press releases trumpet potential renewable ventures while drilling plans expand unabated.

Why does this matter? Greenwashing and climate denial share a core objective: to postpone the deep emission cuts claimed by scientists as urgent this decade. [IV] Whereas denial disputes the crisis, greenwashing misleads the public into believing problems are solved, thereby eroding consumer advocacy of genuine environmental actions and stalling regulatory reforms. In effect, it acts as a soothing lullaby, guiding society ever closer to ecological breakdown while fostering a false sense of progress. Exposing the facade-and insisting on verifiable, measurable carbon reductions-is essential if rhetoric is to give way to real action.
