Using an example, explain how a city can be made more sustainable.
Explain means: Give the reasons why something happens, developing each point with "because" or "so".
Level 1 (Basic)· 2/6 marks (band 1–2)
Cities can be made sustainable by using solar panels and having trams. Recycling also helps.
Why this level: Relevant strategies listed, but no example and no explanation of why they are sustainable. To reach Level 2: use a named example and explain how each strategy helps.
Level 2 (Clear)· 4/6 marks (band 3–4)
In Freiburg's Vauban district, the Solar Settlement's homes have solar panels that produce more energy than they use. A tram line runs close to most homes, and cars are parked at the edge of the district, so many households have no car, which cuts emissions.
Why this level: Clear, named example explaining energy and transport. To reach Level 3: develop more strategies, such as water, green space and waste, with detail.
Level 3 (Detailed)· 6/6 marks (band 5–6)
In Freiburg's Vauban district in Germany, the Solar Settlement's 59 homes have solar panels that produce more energy than they use, so they cut carbon emissions and sell spare electricity. A tram line runs within a short walk of most homes, and cars are parked in garages at the edge of the district, so about 40% of households have no car, reducing pollution and congestion. Rainwater from roofs soaks into the ground through green spaces rather than running into drains, reducing the risk of flooding. Residents sort their waste for recycling and composting, so less goes to landfill. Together, these make the district more sustainable, meeting people's needs without harming the future.
Why this level: Detailed, accurate use of a named example across energy, transport, water and waste, each linked to sustainability. This is Level 3.
