Design for Environment
A snowboard has very low greenhouse gas emissions in use. The only emissions associated with use are the additional emissions from transport, which we consider negligable if transported inside a vehicle, but could be significant if transported externally as for example on the roof of a car which would add drag.
The emissions caused by the added drag can be estimated by considering a increase in fuel consumption of 5% when using a ski rack [X]. When estimating an average driving distance to snowboard as 200 miles, a car with 20 miles/gallon, 5 trips/year, a 10 year life span and an average of 3 snowboards in the rack, the amount of gas needed to compensate for the ski rack can be estimated to 8.3 gallons. Considering 8.9 kg CO2 per gallon of gas [Y], the total CO2 emissions from the use of a snowboard is approximately 75 kg. For such a rough estimate it is natural to round it to the order of magnitude of 0.1t CO2.
To estimate the amount of CO2 emissions from manufacturing we used the EIO-LCA method. This gave a total of manufacturing emissions as 0.25t CO2 when considering an average price of 400 dollars for a snowboard.

However the method is very unprecise in our case as snowboards only represents a small fraction of the sporting and athletic goods manufacturing sector, so the value found represents the average emissions from all sports equipment which could vary enormously from one product to another.
