Gas-and diesel-swilling internal combustion engines are dirty things, which is why automakers are introducing electric vehicles as emission-free alternatives. Admittedly, "emission-free" is a relative term, as the complexity of manufacturing a vehicle-electric or otherwise-is far from the most environmentally friendly process. Nevertheless, the automotive industry has taken and continues to make steps to lessen the negative environmental impact its processes and products create. Many companies are preparing to ditch the internal combustion engine entirely, while others are committing to a carbon-neutral future to reduce or offset their carbon emissions, which contribute to Earth's warming environment.
