CarbonDiem may help save the planet
An invention by Andreas Zachariah, a student from the Royal College of Art in London, may help to save the Earth from disaster.
Every journey you make by car or public transport results in a significant amount of carbon dioxide (CO2) being pumped into the air. This is known as your carbon footprint. Many people are now concerned about global warming, which is thought to be caused by rising levels of CO2. They are looking for ways to reduce their carbon footprint. One option is to use public transport and limit journeys by car and plane. But how can you measure the benefits of choosing a bus or a bicycle over a train or car?
CarbonDiem is a prize-winning personal carbon calculator. It consists of a key ring sensor that detects a person’s movements. Using data from navigation satellites, it can track the distance and method of travel for every journey. It then calculates how much CO2 has been generated and displays the results on a mobile phone. Once they know the carbon footprint for each journey, travellers can choose the method of travel most likely to reduce the amount of carbon dioxide released into the atmosphere.
"We have now tested our application using GPS and it has proved to be very efficient,” said Zachariah. “Once Galileo, the European global navigation satellite system, becomes fully operational, its increased accuracy will help CarbonDiem to measure journeys and then determine their carbon footprint.”
