Because a car requires many raw materials and much energy to be made, the manufacturing process produces various pollutants and wastes as byproducts.
Because most cars run on a fossil fuel, they emit various gases. As the gases emitted by automobiles have been known to be harmful for human health and the environment, HMC, for the last four decades, has concentrated many efforts on developing a technology that can reduce the quantity of gases emitted by cars. However, the recent fluctuations in the oil market as well as the warning signs of climate changes now lead HMC to pursue the development of the carbon-dioxide-reduction technology and the reduction in the fuel expenses even more vigorously. In addition to the car's fuel efficiency and the amount of carbon dioxide gas it emits, another important area to consider is what types of fuel-efficient cars. In short-run, hybrid and diesel-based cars seem to have a chance. In the long-run, however, cars are expected to finally outgrow their dependency on oil. Thus, HMC, in addition to developing hybrid-electronic cars, is also leading the research and development of other types of eco-friendly cars running on hydrogen, electricity, bio-fuels, etc.
Environmental Effects of the Automobile-Emitted Gases
a well-known greenhouse-causing factor, CO2 aggravates the greenhouse effect on the surface of the Earth, leading the upward changes in the planet's temperature.
mostly in the form of fine dust, these matters cause various respiratory diseases and harm the human body.
cause acid rain and smog, affect the ozone layer, and aggravates the global warming.
produced due to incomplete combustion of the fuel, this gas poses a great threat to the human body, and is, thus, placed under strict regulation.
A car leaves behind wastes after being disposed of. HMC puts great efforts to produce recyclable cars that do not leave behind any wastes. The company vigorously pursues the principles of 3R (Reduce, Reuse, Recycle), focusing especially on the 'recycling' aspects. The final objective is to create a car based on the resource-circulatory system found in the natural ecology, using recyclable materials to build it.
Lifecycle Emission: the car emits various gases (CO2, PM, NOx, CO)
Manufacturing: produces aquatic pollutants, waste materials, and other gases as byproducts by consuming raw materials,
energy, aquatic resources, etc.
