Growth in last-mile deliveries over the next decade could contribute to slower commutes and greater carbon emissions in the world’s major cities, according to research published Friday by the World Economic Forum.
Citing a projected 36% rise in the number of delivery vehicles in the top 100 cities globally by 2030, researchers estimate emissions from delivery traffic will increase by nearly a third and congestion will rise by over 21%. That congestion would translate to an additional 11 minutes of commute time for each passenger every day.
Already, cities are feeling the pinch from the explosion of e-commerce. Delivery trucks regularly pull over in bike and bus lanes or double-park, disrupting public transit and creating a bottleneck for other drivers attempting to pass.
The Forum’s analysis suggests that effective double-parking enforcement or allowing the use of express lanes for delivery vehicles could reduce congestion by up to 29% and 18%, respectively. Mandated night time deliveries could have a similar impact, reducing congestion by 15 percent and cutting delivery costs by 28%.
Coupled with the rise in everyday e-commerce, companies have ramped up competition over delivery times, creating a greater urgency for last-mile delivery. In 2019, for example, Walmart was quick to roll out its own plan for next-day delivery less than a month after Amazon announced it would offer one-day shipping to Prime members.
The Forum’s researchers call same-day and instant delivery the “fastest-growing segments in the last-mile environment,” estimating that by 2025, same-day deliveries will account for 15% of all products ordered online in the U.S.
If current trends continue alongside this rise in the number of delivery vehicles, cities will be hard-pressed to meet decarbonization targets.
A few e-commerce players are already touting efforts to mitigate their CO2 emissions. Amazon, for one, announced a 100,000-vehicle order of electric vans from start-up Rivian Automotive in September and said 40% of its delivery fleet already runs on renewable energy. It aims to reach 100% by 2030.
Actions like these can offer clear improvements on their own, the Forum’s report indicates, but could be more effective with mandated changes from regulators.
For instance, in a scenario where electric vehicle-adoption is mandated by policy, the researchers project a whopping 60% reduction in CO2 emissions by 2030, versus a 24% decline in the alternate, “customer choice” scenario which includes some regulation but is primarily based on voluntary changes in behavior.
Without any voluntary or mandated intervention by government and players in the last-mile ecosystem, the report’s authors warn, “e-commerce and correlated last-mile traffic will immediately pose severe challenges to cities in the next one to three years.”
