Going underground? The innovations cleaning up freight transport

• Switzerland is building an underground network to transport freight that should be operational by 2031.Underground pods for freight alleviate surface traffic congestion, reduce emissions and help ensure consistent delivery schedules.As populations increase, transportation of people and goods needs to improve in tandem and the future of mobility is a key plank of the World Economic Forum’s work.

British punk rock band The Jam sang about “going underground” back in 1980 and, almost a decade before that, fictional children’s TV characters The Wombles created a subterranean network to collect and recycle human rubbish beneath London’s Wimbledon common.Now, as populations grow around the world, the idea of going underground is once again moving back up the agenda. Many of our most pressing economic and social development challenges are interlinked with transport, which accounts for about 64% of global oil consumption, 27% of all energy use, and 23% of the world’s energy-related carbon dioxide emissions, according to the International Institute for Sustainable Development. The future of mobility and transportation is a key plank of the World Economic Forum’s work to help businesses and policymakers develop smarter, cleaner and more inclusive practices.In Switzerland, a company called Cargo Sous Terrain is building a vast underground network of tunnels for self-driving pods to transport freight across the country. The underground cargo system has a target date of 2031 and would reduce reliance on trucks.

The planet’s population is growing and the need for logistics is increasing lockstep, with transportation networks being stretched to their limits. Going underground could relieve the strain on our green spaces and help to reduce emissions. Global transportation activity is expected to double by 2050, and that will boost emissions unless serious decarbonization plans are put in place.

What is the Forum doing to help cities to reach a net-zero carbon future?

In a major step, nine cities and more than 70 organizations in 10 different sectors have come together to build further momentum for a new multi-year initiative: Net Zero Carbon Cities.Together with the Forum, they have created a vision for the future and launched a new framework to help cities rethink urban ecosystems, ensuring that they are greener, efficient, resilient, circular and more equitable.

From policy-makers to businesses, city administrators, civil society and the financial sector, the World Economic Forum is convening a range of stakeholders with a role to play if global cities have a chance of reaching the net-zero carbon goal by 2030.Companies can join the integrated approach to help shape city ecosystems to become net zero carbon by joining a Forum platform.

At the same time, there’s increasing demand to move goods from one place to another and many of us now expect the speedy delivery of items to our homes. The global logistics industry had an approximate market size of $10.4 trillion in 2022 and is forecast to expand to $14.1 trillion by 2028, according to Statista.

Billionaire Elon Musk was inspired to launch The Boring Company, an infrastructure and tunnel-building company, in late 2016 after getting stuck in traffic and thinking that going underground could save time and cut emissions. “To solve the problem of soul-destroying traffic, roads must go 3D, which means either flying cars or tunnels are needed,” the Boring Company’s website says. “Unlike flying cars, tunnels are weatherproof, out of sight and
