    Default Older but enlightening read - The Complete Impact of Bicycle use

    https://drive.google.com/file/d/0By8...ew?usp=sharing

    It's a long read (and a little out dated) but there's some interesting information inside.


    Total Freshwater Used & Consumed

    Of the six products considered, the carbon fiber composite products use and consume the most water. In fact, over 65,000 liters of water are used to make one Roubaix frame and over 30,000 liters are used to make one Roubaix fork. Considering Specializedís annual sales of this bicycle frame, enough water is used to fill almost 523 Olympic swimming pools each year. According to the World Health Organization, a minimum of seven and a half liters of water is needed per person per day to meet daily requirements (World Health Organization, 2014). When applying this assumption, Specialized uses enough water while making Roubaix frames to supply water needed for over 477,000 people per year. These numbers are staggering, but they do not fully represent the problem without reviewing the total freshwater consumed. About 2,300 liters of water are consumed when making one Roubaix frame compared to approximately 1,600 liters consumed to make one Allez frame. To normalize this data, the total water consumed per one kilogram of product was calculated, which reveals the true impact of carbon fiber. 2,160 liters of water are consumed to make one kilogram of a Roubaix frame compared with 1,490 liters per kilogram of Allez frame. Annually, Specializedís Roubaix frameset manufacturing consumes enough water to fill over 25 Olympic pools and provide approximately 23,000 people with water for a year.
