Renault ECO vs Start Stop - Tony Swiss

What do Renault mean when they describe a car with the 1.5 dCi 100 engine as 'ECO'?

What do they mean when they describe a car with the 1.5 dCi 100 engine 'Start Stop'?

I notice that the emissions are lower and mpg is higher on the 'Start Stop'.

What is the difference?

Thanks

Don't know about the Eco but Start/Stop will mean the engine cuts out when you stop the car and put it in neutral at traffic lights, roundabouts etc and then start agin when you put it in first.
