CADWEB - Project extranet and project collaboration extranets
The table below allows you to calculate how much carbon you will save on your project by employing Cadweb, rather than using traditional methods of document exchange and control.

We only calculate CO2 emissions saved from travel, print and post. Therefore, this calculator shows the most conservative carbon offset figure that results from the use of Cadweb. In reality this figure will be much higher, but as it varies between projects we do not include it.

The calculator uses the UK government’s vehicle emissions data and the DEFRA carbon offset methodology.

Please insert the Design and Construction cost of your project less the land acquisition cost (e.g. for a £10,000,000 project put in 10)

Assumptions 
An average issue of information contains 6 files. 
- The average distance for a reprographics delivery is 3 Km. 
- All calculations based on the use of a Ford Transit Connect Diesel 1.8 Van travelling one way 
(It is assumed that the return journey would usually be taken up with another delivery). 
- 10% of the information is still printed and delivered. 

Emissions figures, formulas, calculations and methodologies are taken from the Vehicle Certification Agency www.vcacarfueldata.org.uk
