A new study has reaffirmed what many already suspected—electric vehicles (EVs) are significantly cleaner over their full lifespan compared to internal combustion engine (ICE) vehicles. According to the International Council on Clean Transportation (ICCT), EVs now emit 73 percent fewer carbon dioxide emissions over their lifetime than gas-powered vehicles, a substantial improvement from just a few years ago. The study, which assessed vehicles across a 20-year lifecycle, highlights how advancements in EV technology and cleaner energy grids are accelerating environmental benefits.

This 73% figure marks a 24% improvement over the ICCT’s 2021 report, driven by increased efficiency in EV design and energy use. The findings account for every stage of a vehicle’s life—from mining raw materials to manufacturing, day-to-day use, and eventual recycling. Despite ongoing concerns about the environmental cost of battery production and material sourcing, EVs still offer a significantly lower overall emissions footprint.

The report also found that traditional hybrids and plug-in hybrids (PHEVs) have improved, but not nearly to the same extent. Standard hybrids now produce 20% fewer emissions than ICE vehicles, while PHEVs show a 30% reduction. However, only full battery electric vehicles (BEVs) were found to offer large-scale emissions reductions under current energy mixes, making them the clear leaders in long-term sustainability.

As more countries, including Canada, work toward stricter emissions standards and greener transportation solutions, studies like this support the shift toward electrification. Whether it’s daily commuting or long-distance travel, EVs are becoming an increasingly responsible choice for drivers looking to lower their carbon footprint—without sacrificing performance or convenience.
