Why does green petrol smell different from leaded petrol ... 

So-called green petrol is a preferred alternative to leaded petrol it contains about 3 per cent of the aromatic hydrocarbon benzene (C6H6, IV) as an additive, the benzene acting as a lead-free alternative to PbEt4 as an anti-knocking compound. 

The PbEt4 in petrol does not smell much because it is not volatile. By contrast, benzene is much more volatile - almost as volatile as petrol. The vapour above green petrol, therefore, contains quite a high proportion of benzene (as detected by its cloying, sweet smell) as well as gaseous petrol. That is why green petrol has a sweeter smell than petrol on its own. 

Finally, one of the better books to analyse the environmental impact of petrol is Green Chemistry An Introductory Text by M. Lancaster, Royal Society of Chemistry, Cambridge, 2002. 

The free base is obtained by rubbing the moist salt (5-10 g.) under sodium carbonate solution in a separating funnel and shaking with ether until the whole is dissolved. The beautiful emerald green solution is first concentrated on the water bath and then the solvent is allowed to evaporate from a flat dish exposed to the air. Large green plates of nitrosodimethylaniline remain. They melt at 80° and can be recrystallised from petrol ether (boiling point 60°-80°).

Finally, the cannabinoids can be extracted from the herbal material or the resin to produce hash oil. The latter is obtained from the extraction of cannabis plant material with a suitable organic solvent (for example, petrol or ether) by refluxing. Once a solution of the required strength has been obtained, the solvent is evaporated and the oil concentrated, giving a sticky green, olive or brown residue.
