@UK PLC and CenSA Collaboration Agreement

@UK, the AIM-traded provider of eProcurement software and The Centre for Sustainability Accounting ("CenSA") in York, have agreed to pool their respective technologies to create two new areas in sustainability analysis, targeting both the public and private sector:

·; GreenInsight, which uses @UK's SpendInsight spend intelligence data, combined with CenSA's Input-Output models, to provide a fully automated sustainability analysis of every individual item purchased; and

·; GreenMarketplace which uses @UK's automated and manual classification e2class to identify all the products on the @UK marketplace. Combined with CenSA's Input-Output models GreenMarketplace provides carbon footprints for all the individual products being purchased through the marketplace.

The two services will be available to users of @UK's online eMarketPlace. @UK and CenSA will market these services to both public and private sector organisations to enable those organisations to reduce purchasing costs, speed up purchasing processes whilst gaining a far greater insight into the sustainable nature of their purchases.

GreenInsight income share

The income from GreenInsight will be shared between @UK and CenSA on a 50/50 basis. There are approximately 5,000 public sector bodies of a significant size. Previously an analysis such as Green Insight for the NHS would have taken a number of years and would only provide aggregate figures by product category. The @UK CenSA collaboration means that SpendInsight is able to analyse the spend in a matter of days to a much higher level of accuracy by specific product. The input-output data from CenSA is then used to build up the sustainability impact as soon as the SpendInsight data is available.

This breakthrough in cost, speed and accuracy is also available to private sector companies, and allows CSR reports to be quickly generated to a much higher level of accuracy. Further information is available at http://www.green-insight.com.

Green Marketplace and carbon footprint calculation income share

All income from calculating the carbon footprint of products will be shared between @UK and CenSA on a 50/50 basis. There are approximately 3.6 million artificial intelligence classified products in the @UK system. These need to be analysed to e2class before the carbon footprint can be calculated. The manual classification to e2class costs @UK's customers approximately £3 per product (although @UK PLC is providing a 50 per cent. discount to its customers as part of the Green Marketplace launch). Carbon footprints are charged at a further £1 per product per year. Further information is available at http://www.beta.uk-plc.net.

Ronald Duncan, Executive Chairman of @UK PLC commented:

 "The combination of our granular proprietary spend analysis software with CenSA's Input-Output models for sustainable accounting mean that suppliers of products in our Green Marketplace are able to demonstrate the carbon footprint of each and every product, whilst purchasers of those products will be able to demonstrate their commitment to sustainable accounting through the offset of that carbon. We are excited about the potential of these services and believe that by making universal carbon accounting possible we are removing the barriers to Green Accounting."
