Global warming has become a major concern over the last few decades mainly due to the increase in the carbon footprints left transporting people and goods from place to place. Concerted efforts are being made by governments, corporations, and individuals to cut carbon emissions and seek more eco-friendly means of transport. While individuals opt for car-less days, cycling or slugging, factories provide electric carts and solar powered vehicles within their premises for employees and visitors. Efficient public transport systems such as monorails or Maglev’s encourage more citizens to use mass transit systems instead of personal vehicles.
