That's what Burke's Transport owner Graeme Burke says about a looming end to the supply of a chemical used to reduce pollution in the exhaust of diesel trucks.

Mr Burke says he is hearing different dates from those in the industry about when the nation will run out of AdBlue, but the dates all have something in common: none of them are any later than next month.

"It's pretty serious, no question about that," he said.

Federal Industry Minister Angus Taylor has blamed "global supply pressures, stemming from increased domestic use in China", for problems in securing refined urea, which is key to producing AdBlue.

Mr Burke said the chemical doesn't have anything to do with the running of a diesel truck's engine, but is injected into the exhaust system to break down the pollution produced.

And it's not optional, but a legislated environmental requirement.

"Through more good luck than good management", including securing some from a mate in the transport industry in Dubbo who sold up recently, Burke's Transport has about six months' supply of AdBlue, Mr Burke said.

"Thank god we have been a bit loyal to the people that we have been buying it from," he said.

But he said it was obvious that the Federal Government would need to do something about the problem quickly - whether through offering subsidies or support to have AdBlue made in Australia or changing the legislation "so people can temporarily take vehicles back to the manufacturer and get it [the AdBlue injection] disconnected or toned down until such time as we can get a good supply of it again".

Toning it down, he said, might mean using half a litre instead of one liter per 1000 kilometres.

The Federal Government is reported to have set up an AdBlue taskforce, which will look at options including international supply alternatives for high-purity urea, local manufacturing capabilities and changes to vehicles.
