A brisk transition to zero-emission vehicles is underway, but it's still unclear whether the global transportation sector's makeover is enough to stave off the worst consequences of climate change.
Cars and trucks account for three-quarters of all transportation-related greenhouse gas emissions, including planes, trains and ships, according to McKinsey & Co., and automakers and commercial truck manufacturers will have to accelerate their push to reach net-zero targets by the middle of the century.
Those goals are firm, but the path to achieving them is less so.
"How we get there is not written in stone," Eric Hannon, partner in McKinsey's Center for Future Mobility, told Automotive News. "Frankly, we're moving too slow. We aren't on a trajectory that gets us there yet."
