Your Foodprint
Foodprint is the impact dashboard that turns your local shopping into four headline numbers — money kept inside the local economy, food miles avoided, kilograms of CO₂ saved, and producers you've supported. Every time you order on Parish Larder these numbers go up.
Where to find it
Your personal foodprint lives at /account/foodprint once you sign in. You can also get to it from the Foodprint link in the main site nav, then tap "See my foodprint".
The public page at /foodprint shows the same numbers aggregated across every customer on the platform — broken down by country, region and community. Open it without signing in if you want to compare your parish to the country.
What the four numbers mean
- Kept local — of every £1 you spend, about 85p stays inside the local economy (paid to the producer, not a supermarket HQ). We total this across all your orders.
- Food miles avoided — the average UK supermarket item travels about 1,100 miles farm-to-shelf. A typical Parish Larder order moves around 10 miles. We add up the difference.
- CO₂ saved — a conservative 0.25 kg of CO₂e per £1 of local spend versus the supermarket equivalent. Calibrated to Carbon Trust food-emissions tables.
- Producers supported — the number of distinct local stalls you have bought from.
Your parish numbers
Under your personal totals you also see "your parish" — the aggregate impact of every customer in your postcode area (e.g. GU for Guildford and district). It refreshes as your neighbours shop too, so the parish total is a live picture of local-food momentum where you live.
Methodology
All the heuristics are deliberately conservative. Source figures come from Pretty et al. 2005, Defra weighted food-miles work and Carbon Trust food-emissions tables. We round down at every step — the goal is honest, defensible round numbers, not laboratory accuracy. The exact constants live in the source code at apps/web/lib/foodprint.ts and are documented on the public /foodprint page.
