"Around the world, revolutionary changes are under way in transportation. More
electric vehicles are on the road, people are taking advantage of sharing
mobility services such as Uber and Lyft, and the rise in telework during the
COVID-19 pandemic has shifted the way people think about commuting.
Transportation is a growing source of the global greenhouse gas emissions that
are driving climate change, accounting for 23% of energy-related carbon dioxide
emissions worldwide in 2019 and 29% of all greenhouse gas emissions in the U.S.
The systemic changes under way in the transportation sector could begin
lowering that emissions footprint. But will they reduce emissions enough?
In a new report from the Intergovernmental Panel on Climate Change released
April 4, 2022, scientists examined the latest research on efforts to mitigate
climate change. The report concludes that falling costs for renewable energy
and electric vehicle batteries, in addition to policy changes, have slowed the
growth of climate change in the past decade, but that deep, immediate cuts are
necessary. Emissions will have to peak by 2025 to keep global warming to 1.5
degrees Celsius (2.7 Fahrenheit), a Paris climate agreement goal, the report
says.
The transportation chapter, which I contributed to, homed in on transportation
transformations – some just starting and others expanding – that in the most
aggressive scenarios could reduce global greenhouse gas emissions from
transportation by 80% to 90% of current levels by 2050. That sort of drastic
reduction would require a major, rapid rethinking of how people get around
globally."
