The Manitoba government released more of its action plan on climate change Monday, but critics said it consisted mostly of hot air.

The 60-point plan calls for energy-efficiency standards _ which have yet to be developed _ for residential and commercial construction.

It also calls for new incentives to persuade owners of older cars to trade up to newer models, and for a reduction in stubble-burning on farms.

But the government was not prepared to reveal details such as how car owners would be induced into buying more eco-friendly vehicles.

NDP Energy Minister Jim Rondeau told reporters they would have to wait for specifics.

"It's 60 initiatives that will be rolled out, and as a government, you want to work with your partners to roll out the initiatives,'' Rondeau said.

"I don't want to drop all 60 today because we'd be here all day.''

Other parts of the plan already announced include a commitment to fund 50 per cent of municipal transit and fuel efficiency standards for new vehicles by 2010.

"To me, it looks like more of the same political spin without much substance,'' said Opposition Leader Hugh McFadyen.

Liberal Leader Jon Gerrard said the government's plan is weak. He suggested the province follow British Columbia's lead by imposing a carbon tax on fuel while cutting income taxes by a similar amount.

"We need to be paying lower income tax in this province, and we need to offset that with higher costs for producing greenhouse gases,'' Gerrard said.

The NDP is trying to meet its Kyoto target and cut greenhouse gas emissions to six per cent below 1990 levels by 2012. That requires a cut in annual emissions to 17 megatonnes from 20 megatonnes, the equivalent of pulling a half-million cars off the road.

The province has already made progress on several fronts, most notably by reducing coal use at the Crown-owned Manitoba Hydro.
