How does WARPit reduce Green House Gas and Carbon Dioxide (CO2) levels?

How does WARPit reduce Green House gas and Carbon Dioxide (CO2)  levels?

WARPit matches staff who have surplus or underused resources, with staff who were going to buy a new item.

Every item that finds a new home on WARPit,  stops the purchase of a new item.  It is a no brainer and a win win situation.  When we stop the purchase of a new item- we avoid costs, carbon and waste. Simples.

Carbon and other Greenhouse Gases (GHG) are given off in the manufacture of products. Every item transferred to a new owner using WARPit saves on carbon emissions because a new item does not have to be manufactured, transported and purchased.

The WARPit database knows the carbon value of each category and item transferred on the system and so can illustrate the savings generated when items are transferred. As far as I know this is unique and nobody else is doing this worldwide for redistribution markets. Please email me if I am wrong.

The GHG or Carbon Dioxide Equivalent (CO2e) can be measured by estimating the amount emitted during manufacture, using activity data (such as the amount of fuel used) and applying relevant conversion factors (e.g. calorific values, emission factors, oxidation factors). This conversion factor can then be used to estimate the amount of CO2 in a specified unit.

These conversion factors allow organisations and individuals to calculate greenhouse gas (GHG) emissions  from a range of activities and enable you to convert activity data (e.g. litres of fuel used, number of miles  driven, tonnes of waste sent to landfill) into kilograms of carbon dioxide equivalent (CO2e).

The Carbon Dioxide Equivalent (CO2e) is a universal unit of measurement used to indicate the Global Warming Potential (GWP) of one unit of  Carbon Dioxide.

Using conversion guidelines, we are able to apply conversion factors to various categories (eg furniture or IT) that are transferred on WARPit, producing the Carbon Equivalent saving on each transaction of items in that category.

The conversion factors are calculated by Centre for Sustainability Accounting (CenSA), York, based on previous calculations by Stockholm Environment Institute (SEI), University of York- and are nationally recognised being used by DEFRA and HEFCE.
