A single train fitted with the system could remove thousands of tonnes of carbon every year.



A visualisation of the team's design.Retrofitting direct air capture tech to trains to recover CO2 could help us get back on track in the fight against climate change, a study carried out at the University of Toronto has found.

The tech is already well established, but stationary, ground-based facilities require a lot of land. This has historically led to many residents in the areas near to proposed sites objecting to their construction, the researchers say.

“It’s a huge problem because most everybody wants to fix the climate crisis, but nobody wants to do it in their backyard,” said co-author Prof Geoffrey Ozin, director of the solar fuels group at the University of Toronto.

“Rail-based direct air capture cars would not require zoning or building permits and would be transient and generally unseen by the public.”
