Diesel is not worse than petrol:

Diesel cars tend to have lower volumetric fuel consumption figures than comparable gasoline vehicles. However, the benefit in terms of CO2 emissions is significantly lower, as the combustion of 1 liter of diesel fuel releases approximately 13% more CO2 than for the same amount of gasoline.

I believe the issue with diesel is NO2, basically it may emit less but it's worse for us

Is diesel CO2+NO2 is worse than petrol CO2+NO2 for global warming?

Potentially Diesel has less CO2 emissions than Petrol if that is the point you want to insist on.

The major issue with Diesel is NO2 emissions, on top of respiratory issues directly attributed to NO2 in city centres, NO2 is also a reducer of human longevity. [0]

I would say anything that is slowly killing us and reducing our lifespan should be pretty high on our priorities list.

But with a liter of diesel (usually) you can make more kms than with a liter of gasoline. I'm not sure the CO2/km of each class of motor, though

imho both effects stem mostly from the fact that diesel has ~11% higher density than gasoline.

(ie. mileage and co2-output become more equal if measured against mass rather than volume)
