The phasing out of diesel could be started in a matter of years.
Private diesel vehicles can go from day 1 - there are plenty of alternatives.
Commercial diesel vehicles may take longer, though there are already alternatives - fuel blending can be retrofitted as an interim solution.

Since gasoline engine exhaust was put on the list of "CHEMICALS KNOWN TO THE STATE TO CAUSE CANCER OR REPRODUCTIVE TOXICITY" in 1990, I don't believe they were only referring to gas engines which have direct injection.

The particles are the issue with diesel.
Ever better direct injection systems have created ever smaller particles, with DPFs producing the smallest particles of them all.
With petrol direct injection, we're adding the PM issues to petrol engines as well ... where the problem didn't exist before.

We live in a dangerous world, where our own advances in technology expose us on a daily basis to chemicals and products which increase the risk of cancer or birth defects or other many other illnesses that we'd not encountered before the technologies were developed.

We've replaced an ancient set of clear and present dangers, with a modern set of sneaky, obscured, and long-term hazards.
Technology has enabled us to live a lot longer - that's only one side of the coin.
The flip side is it's also endangering us to some degree.
