How Is KR 1.5 Tracking?
Our Miles KR ties most directly to emissions cuts. By focusing on total miles driven, it accounts for 80 percent of transport emissions and all vehicles on the road, from newly minted EVs to the oldest and dirtiest gas-powered cars and diesel trucks.
One impediment to achieving this key result is the protracted vehicle turnover cycle. In the U.S., the lifespan of the average new car exceeds 12 years. Even after we achieve 100 percent market share for sales of new EVs, it will take more than a decade to get the last combustion engines off the road. Globally, 10.4 percent of total miles were electric in 2022, up from 8.6 percent in 2019. Given the sheer scale of the 18 trillion-plus miles driven worldwide each year, getting that proportion to 50 percent by 2040–or 95 percent by 2050–will take a huge concerted effort.
