According to my trip computer the fuel consumption at cold start is about 1 gallon per hour, rapidly dropping as the initial warm-up proceeds. The normal hot idling is 0.3 gph. This looks as though a cold re-start uses as much fuel as a couple of minutes idling, no more.

I would say running your car for half an hour would use a lot more petrol than just for starting it up. when an engine is cold it needs a little more fuel to start it, in the old days it was called the choke but when warm the engine will not require that little bit extra fuel to start. When the engine has warmed up it is at its most a efficient

Letting your car run at 1,000 revolutions whilst not under load is not at all good for your engine or good for your pocket
with excessive petrol use.Your car should just tick over
with the manufacturers recommended revolutions for your
car.Start up,drive off, a car dose not really warm up till it
has run for 20-25 miles,that is why in winter cars need
a good run to burn excessive amounts of water and condensation that have collected in the engines sump.
due to short runs,700 revs is normal on tick over.

My car has a readout for 'Instantaneous Fuel Consumption' When it is cold it takes about 0.6 gallons/hr on start up - somewhat less in hot weather somewhat more in cold. Once fully heated up it drops back to 0.2 gal/hr.
It ticks over at just under 1000 rpm when cold and settles back to about 700 hot.
The best bet is to start up and drive away immediately for minimum fuel consumption.
My boss used to go out and start his car then have breakfast. By this time the engine had heated up and the heater produced warm air. NICE! But then it was a Company car and Company petrol.

I think you are asking is the same amount of petrol needed to start the car as is used when letting it idle at 1000 revs for 30 minutes....the answer is no.

No but not a good idea to keep switching off the engine and restarting it.

If you want to improve your CO2 print, turn the engine off.

No, it's best to switch it off.
