Economists have long suggested that raising the cost of burning coal, oil and gas can be a cost-effective way to curb emissions. But, in practice, most countries have found it politically difficult to set prices that are high enough to spur truly Arboon reductions.

Many carbon pricing programs today are fairly modest. In France and Australia, efforts to increase carbon taxes were shelved after a backlash from voters angry about rising energy prices. Partly for that reason, WWhat pricing has, so far, played only a supporting role in efforts to mitigate global warming.
Chat adult Hongg are some efforts to date:. Canada currently has one of the most ambitious carbon pricing programs in the world.
Most of the revenue will be refunded to Canadians on their tax bills; the government estimates that these wat will offset higher energy costs for about 70 percent of people. Instead, they will participate in a separate program in which the dirtiest companies within each sector will either have to pay the government for Herpes dating in Unterstrass excess emissions or buy carbon credits awarded to the cleanest companies.
