How green and eco-friendly is your electric car?Electric vehicle | Sustainability
Definitely, electric car is zero-emission, more sustainable and greener and with a lower environmental impact than any combustion car.
## Reasons for the growing demand for electric vehicles Tesla, the leading brand in electric car sales in Europe and worldwide, is more valuable than the next nine competitors. This is partly due to the **rising consumer demand for electric vehicles**, and a spate of **government regulations** aimed at both phasing out traditional combustion engines within the next decade and decarbonizing countries’ economies. The reason why demand has increased is partly **economics**. Although electricity markets around the world vary, it is almost always cheaper to use an electric vehicle than any diesel or petrol car, even the initial purchase is somewhat higher.
## The electric car is excellent at tackling air pollution While there are a number of reasons why regulators (and users) are beginning to prefer electric vehicles, the most discussed are carbon emissions and air pollution. In terms of climate impact, according to European Commission, **combustion engine vehicles currently emit** around 30% of the EU’s carbon emissions (72% of which come from road transport) and 28% of the United States' carbon emissions. In addition, there have been significant concerns raised about the health of individuals living in cities with high traffic pollution due to combustion car engines. In fact, it is estimated that approximately **3.5 million premature deaths a year are due to ambient air pollution**.
So, when it comes to **local air pollution** (such as fine particulate matter or PM and nitrogen oxide or NOx), **electric vehicles are a complete win** as they are zero emission.Such chemicals are short-lived in the atmosphere. So even if an electricity plant were to produce energy from non-renewable sources, the pollution would be omitted outside city centers and would therefore cause **minimal damage**. The situation is more nuanced when it comes to carbon pollution. **The cleaner the power plant, the cleaner the electric vehicle**. But even in this case, we can't directly compare power plant emissions for an electric vehicle with the direct emissions of a combustion engine vehicle. **Direct emissions from an EV are zero**.
It's just **indirect emissions that matter and they exist for combustion-based cars too** (and at a much higher rate). Emissions from a **tank of petrol** are not just due to the petrol burned but also to the emissions needed to **extract the fuel** and those required to **transport** it to the vehicle.Another point that needs to be considered is the **secondary effect of petrol and diesel production**. In order to feed combustion engines, we need to use oil. This process has a significant impact on the environment in and of itself. Did you know that an average combustion engine car burns around 17,000 liters of oil in its lifetime? ## How green your electric car depends on where you live A major argument leveled against electric vehicles is that they don’t reduce emissions, they simply move them. While there is some truth in this argument, we must bear in mind that: **Even in the worst-case scenario, the electric car is still more green**. To be more precise, according to the Transport & Environment study, an electric car emits **22% less** **CO2 than a diesel** and **28% less** **than a petrol** (taking into account electricity that comes from burning fossil fuels, both in the manufacture of the battery and the energy used during its use). And yet, **we save tons of CO2**! But **at the best-case scenario, we save 80% of CO2!** Not to mention that an electric car generates **neither fine particulate matter nor nitrogen dioxide** (NO2) like diesel cars, which are seriously harmful to our health.
The **European Union** has proposed a measure that will include goals (and mandatory requirements) for the **whole lifecycle of electric vehicle batteries** to minimize their environmental impact.The aim is to make the production processes of these batteries significantly greener and thus contribute to meeting the climate decarbonization goals set out in the European Climate Law to combat **climate change**. The measure proposes that such **batteries** should be **carbon neutral and recyclable** for a high percentage of their raw materials by 2030 (to be more specific, 95% for cobalt, 70% for lithium, 95% for nickel and 95% for lead). To reach this target, the proposal states: - From **2024**, all batteries sold in Europe would have to publicly declare their **carbon footprint**. - From **2027**, it would be mandatory to **declare the amount of recycled raw materials** used for their production. Not only that, but Brussels is proposing to set 2027 as the deadline for not allowing the sale of any battery or electric car that does not respect the CO2 emission limits. Last but not least, this measure establishes a framework to promote the **reuse of electric vehicle batteries** with the aim of giving them a second life, either as **energy storage systems** or as part of the electricity grid as an **energy resource**. ## Progress is just around the corner A number of startups are already working on this challenge. For example, Redwood Materials is working on a breakthrough method that combines leeching and hydrometallurgy to maximize the recovery of materials from the battery. The company claims that their process can recover between 95 and 98 percent of a battery’s nickel, cobalt, copper, aluminum, and graphite, and more than 80 percent of its lithium. Other companies, such as Li-Cycle have worked on a refined leaching process that doesn’t produce any wastewater.
If these processes can be refined, and battery manufacturers put recycling at the heart of their designs, it will be possible to **significantly reduce the number of environmentally damaging materials** needed for new electric vehicles.So, there are very real challenges ahead with electric vehicles, but few of them are due to the cars themselves. The shift towards renewable energy has already begun, and even if you live in China, **electric vehicles will still be less damaging** and ultimately cheaper than buying a new combustion engine car. However, in order to **maximize the green potential of electric vehicles** and to make them 100% zero emission in all their processes, further work needs to be done to adopt 100% sustainable energy grids.
