Plug-in hybrids (PHEVs) are marketed as environmentally friendly, yet studies reveal they are often used primarily in gas mode, leading to higher emissions than expected. In Canada, PHEVs comprise a small percentage of new car registrations but help manufacturers meet emissions standards. Recent data shows that PHEVs use electric mode only about 30% of the time, significantly lower than the anticipated 80%. As Canada reassesses its electric vehicle regulations, the treatment of PHEVs under these rules remains a contentious issue.
