Other metal components, such as aluminum used in some engine parts and wheels, for example and copper used for wiring are also largely recycled. The lead and acid in batteries are poisonous and dangerous. But batteries can be recycled, if they are returned to a service station, a parts store, or brought to a municipal hazardous waste facility. Plastics, which are mostly made from petroleum, are more difficult to recycle.
In any case, some degree of pollution is associated with all of these components, much of it due to the energy consumption, air pollution, and releases of toxic substances that occur when automobiles are manufactured and distributed. Most of the environmental impact associated with motor vehicles occurs when they are used, due to pollution in their exhaust and pollution associated with supplying the fuel.
In the United States, nearly all of today's automobiles use gasoline; a lesser number use diesel fuel. In some areas, various alternative fuels are being introduced, but these are not widely available for most drivers. When gasoline, diesel, or other fuels are burned in car engines, combustion is never perfect, and so a mix of hazardous pollutants comes out the tailpipe. If combustion were perfect and didn't create noxious by-products, the exhaust would contain only water vapor and carbon dioxide.
Carbon dioxide CO 2 isn't directly harmful to health, at least not in low concentrations. After all, co 2 is also what we exhale after "burning" the calories in the food we eat.
However, co 2 from fossil fuels like gasoline and diesel is very harmful to the environment because it causes global warming-more on this pollutant shortly. Motor fuel is itself a product and so, like a car, environmental damage occurs throughout its lifecycle as well. For gasoline and diesel, the product lifecycle begins at the oil well and ends when the fuel is burned in the engine.
Fuel cycle impacts are the forms of pollution and other environmental damage that occur between the oil well and the fuel tank. Gasoline and diesel fuel are poisonous to humans, plants, and animals, and their vapors are toxic. This issue can be difficult to tease out of other factors, such as population growth and resource consumption, but it is also not easily addressed by technological advancements like fuel efficiency and electric propulsion.

Because electric cars store energy in large batteries the larger they are, the bigger their range is that have high environmental costs. This happens because these batteries are made of rare earth elements REE like lithium, nickel, cobalt or graphite that only exist beneath the surface of the Earth and therefore depend on mining activities with very polluting processes.
In spite of these pollution issues, research tells us not to worry about the availability of these rare earth elements and when it comes to lithium, there is data estimating enough worldwide reserves for the next years, even if the EC market triples, according to the Deutsche Bank. As for cobalt, graphite, and nickel, they also seem to be in a comfortable situation, since the demand for the years to come is expected to stay far away from the reserves Earth has to offer.
Nevertheless, forecasts show that the electricity generation is improving and there are more renewable sources entering the grid, which would help decrease the ecological footprint of building up these batteries. On the other hand, developing renewable energy systems has its impact as well, again using energy and REE. In the end, we should be reasonable about this and despite their initial footprint, the impact of lithium-ion batteries, when compared to conventional cars, is offset within 6 to 16 months of average driving using clean energy in the US or 2 years in the EU.
From this moment on, EC keep being a better eco-alternative to conventional cars until their battery gets to the end of its life cycle. But what happens next? Nevertheless, the more batteries that are out there, since the electric cars market is growing, the more interesting it gets to try to figure out how to recycle them or recapture rare earth elements. So the chances are that a strong recycling industry for these batteries will keep developing and allowing electric cars to become greener.
Meanwhile, another solution might have to do with reusing these batteries and giving them a second life since they are able to support the electric grid of buildings and to store energy from wind or solar electricity sources. This would also help offset the environmental impacts of making the batteries in the first place since they are amortized over a longer period of time. No, electric cars they are not zero emissions vehicles. We have seen that although they do not emit CO2 while being driven, they might do it in 3 other stages: during manufacturing, energy production and at the end of their life cycle.
In the first case, the need for mining activities to extract the rare earth metals that are used in batteries is very energy consuming and polluting. As for the energy production, if the car is being powered with energy from burning fossil fuels, it is still releasing CO2 in the atmosphere, not from the tailpipe but from some distant power plant. When it comes to batteries being recycled, it is still an expensive and ongoing process and most batteries are not being recycled yet.
In spite of this, solutions to make electric cars greener and more eco-friendly and sustainable are being developed. And although there is room for improvement, we have also seen that electric cars, as they are today, are already, in general, more eco-friendly along their lifecycle than the conventional fossil fuel cars, especially if they are powered with clean electricity. In fact, countries like Norway, Germany or Costa Rica are simultaneously increasing their bet on renewable energies and setting deadlines for the end of conventional cars in their roads.
But in the end, are electric vehicles the solution for our sustainability problem on mobility? But is preventing the bad the same as planning for the best? We have REE for some time but do we truly have enough for the long run? At the same time, some scientists say that the sharing economy of cars, or even motorbikes or bicycles, will be the next stage in the evolution of mobility, with new business models already being developed.
