At CleanTechnica, we focus on electric vehicles, from small city microcars to massive performance sports cars. And why not? The transportation sector accounts for more than a third – 37 % according to the IEA – of all carbon emissions. But that means almost two-thirds of carbon emissions come from other sources – like cement, which is responsible for around 8 % of global carbon emissions. In other words, the EV revolution is vital, but even if every vehicle on Earth – cars, trucks, planes and ships – were powered by electricity, our planet would still be too hot to sustain human life.
