How can design of public services could make sustainable behaviours the default

- Paraphrase: Building the physical and digital systems people use every day (infrastructure) and removing small hassles (friction) makes sustainable choices the easy, natural option — so people do them routinely without extra effort. - Key terms - Infrastructure — the physical or digital systems that enable behaviour (e.g., public transit, bike lanes, recycling bins). - Friction — any small obstacle or extra effort that discourages an action (e.g., long signup forms, distant recycle points). - Default — the option people get if they do nothing (often set by how infrastructure and processes are arranged). - Nudge — a design change that steers choices while keeping alternatives available. - Why it matters here - Increases uptake: Reliable transit and nearby recycling bins make people more likely to choose low‑carbon options because they’re convenient. - Normalises behaviour: When sustainable choices are routine and visible (e.g., frequent buses, labelled bins), they become social norms that others follow. - Reduces decision costs: Cutting small hassles (one‑click renewables, simple sorting rules) removes barriers that otherwise keep people using unsustainable defaults. - Follow-up questions / next steps - Which local public services (transit, waste collection, energy billing) should be analysed first for infrastructure or friction problems? - How will changes ensure equity — e.g., affordable access for low‑income or mobility‑restricted users? - Further reading / references - Nudge: Improving Decisions About Health, Wealth, and Happiness — Thaler & Sunstein (search query: "Nudge Thaler Sunstein book") - Designing for Behaviour Change — Samuel Salzer (search query: "designing for behaviour change public services")
