Select baselines that reflect local realities: income levels, proximity of hardware stores, presence of rental shops, and cultural attitudes to repairing. Compare scenarios such as new purchase, second-hand, borrowing from a friend, or no action, then weight probabilities from surveys responsibly.
Translate activities into emissions using the latest UK government conversion factors for electricity consumption, van mileage, and courier deliveries. Pair them with hub-specific meter readings and fuel receipts, so your calculations remain transparent, reproducible, and easy to update when annual numbers change.
Guard against inflated totals by considering rebound, like extra projects encouraged by easy access to tools. Avoid double counting with partner reuse schemes. Communicate uncertainty using ranges or Monte Carlo simulations, and include sensitivity checks for travel modes, lifespans, and alternative purchasing pathways.
