Not surprisingly, the fruit and veg box, aimed at households who struggle to cope with our more farm-based, seasonal boxes, has easily the highest sourcing emissions while the more seasonal, home grown boxes tend to have the lowest. For us it has been interesting how large the impact of a single item can sometimes be on the footprint of a single box and it is these items that we are first working on replacing.
For our customers we will make these ratings available on the main Riverford website, alongside the predicted box contents, to allow informed choices to be made. An example of the ratings scale is shown below. To give these some context, a box sourced entirely from our farm would score around 8gCO2/kg and one sourced entirely from South Africa, by sea, would hit 300gCO2/kg, at the top of the scale.
