Shifting to EVs is not enough. The deeper problem is our car dependence

Shifting to EVs is not enough. The deeper problem is our car dependence

CBC
Monday, August 1, 2022 12:41 AM GMT

This column is an opinion by Paris Marx, a technology writer based in St. John's. For more information about CBC's Opinion section, please see the FAQ.

Earlier this month, Prime Minister Justin Trudeau made a bold claim: Canada "isn't just going to be a global player in EVs, … we get to be global leaders." Over the past year, the federal government has been announcing a series of deals with auto companies and suppliers aimed at growing the domestic electric vehicle industry.

With gas prices soaring above $2 a litre for the first time in May and Atlantic Canada's record temperatures serving as yet another reminder that the world is rapidly warming, it's clear that we desperately need to rethink our transport system. But is the government placing too much focus on electric vehicles instead of encouraging more people to ditch their cars altogether?

Electric vehicles tend to produce fewer emissions over their life cycles than equivalent vehicles powered by fossil fuels, but the framing often used by government and industry that they are "zero emissions" is misleading.

Unlike a conventional vehicle whose emissions come from burning fossil fuels, a greater share of an EV's emissions come from its production; more specifically, its battery. This is the side of the EV that often doesn't make it into the ad campaigns.

The International Energy Agency estimates that there will need to be a significant increase in mineral extraction to fuel a green transition that places emphasis on EVs over alternatives like public transit and cycling. For example, demand for lithium is expected to soar by 4,200 per cent and cobalt by 2,100 per cent.

Those figures sound great to the mining industry, which hopes to use EVs to greenwash its operations, but they have severe human and environmental consequences throughout the supply chain.

The "lithium triangle" in South America is poised to be a significant source of the mineral, but already it's polluting the water and lowering the water table, threatening fresh water access for local communities.

Meanwhile, the site of much of the world's cobalt extraction in the Democratic Republic of the Congo (DRC) experiences high rates of birth defects, contaminated water, and around 40,000 children are believed to work in artisanal mines. In 2019, electric carmaker Tesla was among a number of companies named in a lawsuit over child deaths at cobalt mines in the DRC.

But this isn't just happening abroad. Part of the prime minister's pitch for Canada to be a global EV leader is to increase mining as well. Lithium mines in Quebec have already been responsible for environmental accidents and subject to community opposition, while Indigenous opposition is already mounting over plans to exploit the Ring of Fire in Ontario. We're sure to see more as provinces across the country look for mineral deposits to exploit.

In 2019, transportation accounted for 25 per cent of national emissions, second only to oil and gas, and that had grown by 54 per cent since 1990, in part because people were driving more and buying big trucks and SUVs instead of sedans. There's a need to address the transport sector's emissions, but the problem goes beyond tailpipe emissions.

According to Statistics Canada, 73.7 per cent of Canadians live in urban areas, but the majority are in the suburbs, not the downtown core, and those suburbs keep growing. That reality is the product of decades of government policy that incentivized suburban living and prioritized cars above other forms of mobility.

A study released in January found that 83 per cent of Canadians own or lease a vehicle, and 81 per cent of car owners felt it would be impossible not to because so many of our communities have been built to deny residents a reliable alternative. Those suburban communities also have higher carbon footprints than denser urban areas.

But car dependence isn't just an environmental problem. In 2020, an estimated 1,745 people died in motor vehicle collisions and another 7,868 people sustained serious injuries. Commute times are also getting longer in Canadian cities, and sitting in a car is associated with a whole range of adverse health impacts.
