Set against the backdrop of climate change and a growing global push for sustainability, more people than ever before are turning toward Electric Vehicles (EVs) as a simple swap to reduce their carbon footprint – but are EVs really more sustainable? Although they might seem more sustainable, the long-term impacts of EVs on the environment are still not entirely known. While EVs reduce fossil fuel consumption now, what happens to the battery in an EV when it dies? Can it be recycled? How are the batteries produced? All these factors contribute to an uncertainty around EVs that has governments and scientists thinking of ways to improve the sustainability of the EV industry.
