“My intuition tells me that the on‑demand mobility everyone has access to — which allows us to leave our homes and go directly wherever we want — is what has locked us into the carbon emissions we are facing today. Public transport and active mobility are not as demand‑driven. I think we need to move away from the idea that once we step out of our homes, we can go wherever we please. We need to start planning and thinking ahead, because the current level of car‑based mobility is simply not sustainable. And continuing to invest in this particular type of mobility — as opposed to electric cars or private electric vehicles — does not solve the problem. We also have a limited amount of road space in our cities, and that space needs to be available for people who travel together, rather than those who travel separately.”

In this extract, Brian Caufield, Professor and Expert at the National Transport Authority, answers the question: What should be our priority when it comes to mobility?

I think the on-demand mobility that everyone has, which allows us to get out of our homes and straight to where we want to go, is what has locked us into the carbon emissions we're facing.

Public transport and active mobility are not as demand-driven. That's why we need to get away from this idea that we can go wherever we want. We need to start planning and thinking things through, because mobility by car in its current state is simply not sustainable. Continuing to invest in this mobility, as opposed to electric vehicles, doesn't solve the problem.

We have a limited amount of road space in our cities, and this space needs to be available for people who move together, rather than those who move separately.
