This website - https://www.shiply.com/ aims to minimise  journeys by empty goods vehicles.  

The site tries to match businesses or individuals requiring deliveries with courier and transport companies who are going in that direction with an empty or part empty vehicle.  

The site claims to have saved nearly 4,000 tonnes of CO2 by linking goods with delivery companies.  The idea won the Shell Livewire Young Entrepreneur award. An ebay auction type arrangement means those wishing to have goods delivered will receive bids from interested delivery companies.  

If you try out this site, we would be interested in your feedback.
