Almost all car makers around the world are responding to this issue and have begin their research to reduce the risk of climate change. The steps that the car manufacturers have to take to deal with this situation are to reduce the amount of CO2 emissions and waste produced by both of their manufacturing factories and vehicle by implementing new measures in their factories and by looking at using renewable fuels that produce cleaner emission. Another step could be to start producing more hybrid (petrol/electric) vehicles which consume less petrol and produce very small amount of CO2 emission. Leader car makers such as Toyota, Ford, and General Motors have developed technologies that are more environmental friendly. Toyota, as the market leader in the world, show that they are after a new car with economy fuel consumption and low CO2 with their new hybrid synergy drive program and have released an electric powered car such as Toyota Prius which use electric power that does not use petrol when running in a low speed or running out of petrol. This technology, clearly a result because of the climate change issue and they are answering to this global problem. On the other hand, the USA-based car manufacturer Ford also has been on its process in reducing the CO2 emission produced from their factories. From a report by Ford, it is a fact that since 2000, they have the cut the emission of CO2 from their operations by 15% and have benefited from the energy cost savings that go with it. Other manufacturer such as BMW have developed their own technologies in response to this issue by developing a car that only consume hydrogen and emit water vapor as the emission.
