About the Calculators

The calculators were made using BS EN 2050:2008, a British standard for carbon footprinting and all efforts have been made to make them as accurate as possible. However they may change as new data or new processes develop.

There are some basic assumptions that should be known;

  • Surfboard production is assumed to be in the UK, using a UK conversion factor for any  utilities used
  • The foam is assumed to be US made, using a US conversion factor for any utilities used
  • The resin is assumed to be US made, using a US conversion factor for any utilities used
  • The fibres are all assumed to be made in China, using a Chinese conversion factor for any utilities used
  • All overseas transport is by container ship unless known

Simple Calculator assumptions

  • A Longboard is presumed to have a 2+1 fin set up, be 23 inches wide and 2.875 inches thick.
  • A Shortboard is assumed to have a standard thruster fin set up, be 18.5 inches wide and 2.375 inches thick
  • A fish/egg is assumed to an average of a thruster and twin fin set up, be 20 inches wide and 2.75 inches thick
  • A Minimal/Funboard is assumed to be the average of a 2+1 and a thruster fin set up, be 21.5 inches wide and 2.75 inches thick.
  • An epoxy surfboard is assumed to be made with Expanded Polystyrene foam (EPS) and the average of hand shaping and glassing, machine shaped and hand glassing and Pop out manufacture in a 2:2:1 ratio
  • An Unsaturated polyester surfboard is assumed to be made with polyurethane foam (PU) and the average of a hand shaped and glassed board and a machine shaped and hand glassed surfboard
  • Maintenance is assumed to be 5 dings per lifetime, the average is around 4.75 and includes the replacement of one fin plug.

The full data is not available on the website however can be obtained by contacting rick@decarbonated.co.uk, the reason for this is the commercial sensitivity of the data.

Once the carbon footprint has been established for each constituent part, equations were made to represent how much of each material was used depending on the size and shape of the surfboard, information was gathered through literature,professional shapers and personal experience of the process.

This calculator is intended to provide an estimate of the carbon footprint of surfboards and the basic calculator is not as accurate as the full calculator but has been provided for those with less knowledge of how their surfboards have been made. However variables such as where it was made, which specific supply chain has been used and the general efficiency of the shaper can all affect the carbon footprint. The figures in the calculator are subject to change. The results are dependent on the information provided by the customer.
