When it comes to reducing your carbon footprint, it turns out that not everything is simple. Even anything like installing solar panels or hydrogen as fuel can be greener than green if you’re not careful. As with the maximum things in life, making the right selection becomes more confusing as you take a closer look at the problem. Electric cars are no exception. While they seem very at first glance, The Next Web writes in a report released this week, when you look at it more closely, it becomes transparent that they have a really extensive carbon footprint and some drawbacks in terms of lithium extraction. cobalt and other metals.”
The challenge of rare terrestrial metals and expensive minerals included as essential ingredients in electric vehicle batteries is multiple. Not only to increase the value of the car itself, which makes electric cars less available and therefore less used, but it also creates unique and monopoly demanding situations along the chain of origin of electric vehicles. China’s near-general dominance in the lithium-ion battery market has given Beijing an oblique place in the global electric vehicle market for years and has led many corporations to move all of their production to Asia. Meanwhile, cobalt is so expensive that its concentration on the battery of the electric vehicle accounts for a wholly 40% of the total cost of the car.
And then there’s the fact that those metals are not renewable and that their extraction is still green. “The increasing use of lithium-ion batteries as a primary power source in electronic devices, adding cell phones, laptops and electric cars, has contributed to a 58% increase in lithium extraction over the past decade worldwide. It turns out that there is little short-term threat to lithium extraction, but there is an environmental drawback,” writes The Next Web for The Conversation.
So the consultation is: do you value it? How many emissions can electric cars save us and how successful are they to fight catastrophic climate change? Fortunately, I did a lifecycle assessment so we can verify and give us answers.

“Emission lifecycle research takes into account 3 phases,” writes The Next Web. “The production phase (also known as cradle-to-gate), the well-to-wheel phase and the fall-to-cradle phase.” But it temporarily becomes complicated. The numbers in New Zealand, for example, will be very different from those in China. In this sense, the position where your electric vehicle is manufactured is very and where the electrical energy that powers your car is produced is produced. For example, “in New Zealand, 82% of the energy for electricity generation came from renewable resources in 2017. With those maximum degrees of renewable electric power for electric car charging, compared to Australia or China, say, electric cars are higher suited for New Zealand.” But, of course, even this is not so simple. This does not necessarily mean that a Kiwi electric vehicle is impartial in terms of car emissions or that it is not destructive to the environment. That’s why a full lifecycle assessment is so useful.
In the use phase, the electrical power source that the customer uses to force their car comes into play. So, actually, there’s no one-way answer. “To be consistent with perceiving how emissions from electric cars vary by the consistent percentage of a country of renewable electricity, Australia and New Zealand,” the report continues. In 2018, Australia’s steady share of renewable strength in electricity generation was approximately 21%. By contrast, the consistent share of renewable force in New Zealand’s electricity generation combination was around 84% […]. The upward emissions of electric cars (for a battery electric vehicle) in Australia can be estimated at approximately 170 g of CO? consistent with km while upstream emissions in New Zealand are estimated at about 25 g of CO? consistent with km on average. As a customer, your possible options are as smart as your options, and your car is as eco-friendly as your country’s strength combines.
Finally, in the recycling phase, we read about vehicle dismantling, vehicle recycling, battery recycling and curtain recovery. “The estimated emissions at this stage, based on a study in China, are approximately 1.8 tons for a fossil fuel car and 2.4 tons for an electric car (including battery recycling). This difference is basically due to emissions similar to battery recycling that are 0.7 tons. While electric cars generate more greenhouse fuel emissions to recycle than a popular combustion engine, “it is essential to note that recycled parts of cars can be used in the manufacture of long-lasting cars, and that batteries are recycled through direct cathode recycling can be used in the following batteries. This can have significant benefits of long-term emission relief. »
So, here’s what to remember: electric cars are more environmentally friendly, at all grades and at each and every level of life cycle analysis. But maybe they’re not as green as you thought. In fact, there is room for improvement and electric cars are likely to continue to reduce their emissions as they improve technologies. As we speak, Tesla runs on a battery with a lifespan of one million kilometers and no cobalt. The real challenge is to drive the global energy transition towards greener energy production. By then, New Zealand will outperform the most productive of us by 62%. By Haley Zaremba to Oilprice.com
