Conservatives 

The Conservatives still don't believe the Kyoto targets can be met by the 2008-2012 compliance period without triggering a recession. Instead, the Conservatives want to reduce emissions by 20 per cent below 2006 levels by 2020.

The Harper Plan of October 2006 entails:
→ imposing intensity-based regulations on automakers and big emitters over the next five years and extending to 2020.
→ Relying on incentives such as the $230 million as an inducement to companies to adopt clean-energy technologies
→ allowing Canadian companies to buy carbon credits under the Kyoto agreement's clean-energy mechanism in developing countries, something they used to criticize the former Liberal government for contemplating.

Also, Stephen Harper announced that his party will cut the excise tax on diesel fuel in half if re-elected in an effort to reduce the price of consumer goods.

According to their website, other aspects of the Conservative plan include:
→ Reducing greenhouse gas emissions by 20 per cent by 2020 and cut air pollution in half by 2015
→ Creating an "ecoENERGY" plan to encourage more efficient energy use, which would include incentives for individuals and businesses when they adopt pollution reducing practices
→ Creating a trust fund for clean air, which includes support of BC's proposed "hydrogen highway"
→ Planning to regulate chemicals
→ Money earmarked to produce renewable fuels
→ Preserving ecologically sensitive land

Liberals 

The Liberals are focusing on the Stéphane Dion's Green Shift plan; a carbon tax proposal he says is good for the environment and also "good for the wallet".

Here are the main points of the Green Shift Plan:

→ reducing greenhouse gas emissions by 20 per cent below 1990 levels by 2020, with an increase to at least 25 per cent if other countries take on comparable efforts.
→ reduce green house emissions by 80% below the 1990 baseline by 2050
→ investing in renewable energy and conservation,
→ implementing a carbon tax on polluters, which will thereby fund a personal and corporate tax cut
→ proposing a an estimated $15 billion in broad-based income tax cuts to Canadians facing higher energy and goods prices as a result of new taxes on Canadian industries that produce high carbon emissions.
→ new measures, worth about $900 million,aimed at helping farmers, truckers and fishermen adapt to the Green Shift.

According to the Liberals, these methods are meant to help Canadians, but especially low-income earners against rising energy and other costs.

 NDP

→ The NDP wants the Kyoto targets met by 2012; it also wants a further 25 per cent cut in emissions over the 1990 baseline by 2050.

→ The NDP proposes to meet 35 per cent of Canada's energy needs by 2020 with renewable energy, including biomass, wind power and renewable fuels
→ The NDP would legislate short-, medium- and long-term regulations for emissions from the industrial sector beginning in 2008 and requiring overall reductions from that sector of at least 45 MT a year.
→ The NDP plan says it would help underwrite 10,000 megawatts of wind power by 2010

 As part of their platform, the NDP has a "5-point Green Agenda for Canada:"

→ Greener Homes: Make homes energy-efficient resulting in fewer emissions and less expensive home heating bill
→ Greener Communities: Support efforts to expand local renewable energies and retrofit infrastructure
→ Greener Transportation: Mandatory fuel efficiency standards, more green cars, investment in sustainable transportation alternatives
→ Greener Industry: Shift subsidies from dirty energy to clean energy, make industry accountable for greenhouse gas emissions
 → Greener Canada & World: Green the government, work in tandem with international partners

 Green

The Green party has argued for a 30 per cent reduction over the 1990 baseline by 2020 and an 80 per cent reduction by 2050
→ It would also allow for a cap-and-trade carbon market, as well as require solar heating and highest possible energy standards in all new government facilities.
→ the Greens are also calling for a carbon tax, in this case what the party calls a graduated carbon tax that would impose a higher cost on the "dirtier" fossil fuels, such as coal, and less on natural gas.The Green Party also favours a carbon cap-and-trade system as well as more energy efficient rules for cars and trucks, and commercial and residential housing.

     The Green Party supports Kyoto and additionally would regulate polluters through a strengthened Canadian Environmental Protection Act:
→ aiming to keep, conserve and protect water resources, natural parks and habitats
→ attracting the best and brightest scientists for environmental solutions R & D
→ having a goal of zero waste through more aggressive recycling

The Bloc wants Kyoto met, and wants to concentrate on mandating and helping automakers to produce more fuel-efficient vehicles. It would offer rebates to consumers who bought energy-saving cars and tax credits for mass transit users, an initiative the Conservatives brought in). The Bloc also wants government incentives to encourage alternative energy and wind power in particular.
