Our solution is to increase the use of public transportation to reduce the amount of carbon dioxide. With the chip to be added to public transport cards, the more public transport people use, the more free they get. Also, the card reader shows how less carbon is emitted to the nature by preferring the public transport to the personal vehicle and these rates are added every time when the card is scanned. In this way, people sees the benefit it has provided to the environment.It is important because when we prefer using public transportation we release 65 less carbon dioxide in atmosphere.We can organise a hackhaton about carbon footprint,prepare posters, invite famous people for representing our campain in social media. We believe people will become conscious.
