This is a measure of waste being diverted into reuse rather than disposal. Each item that is transferred using WARPit is given an approximate average weight value (KG) based on a sector leading bulky waste guide. If the KG information for an item is not included in the reference document an average weight of the item is estimated using company specification data.
Carbon and other Greenhouse Gases are given off in the manufacture of products. Every item transferred using WARPit saves on carbon emissions because a new item does not have to be manufactured, transported and purchased. Using standard conversion factors we are able to work out the estimated carbon dioxide equivalent. The conversion factors are calculated by Centre for Sustainability Accounting (CenSA), York, based on previous calculations by Stockholm Environment Institute (SEI), University of York
Using the total CO2 saved on each transaction we can work out what the equivalent would be for taking a car off the road for one year. Based on a Ford Focus 1.6TDCi which emits 115g/KM (Source: Ford Motor Company). Assuming an average mileage of 12,000miles per year; a single vehicle would emit 2,300 KG of CO2 per year.
We assume the WARPit user who is claiming an item/s on the system, would have bought the same item/s new. Normally this would take time to get a quote, raise a Puchase Order and process the invoice. This process is avoided using the system and so there is a time saving.
