The next day headlines will celebrate the «stunning» reduction in GHG and Peter Kent will be quoted as saying that Canada has met half of its Copenhagen target (a 50 - something Mt drop would mean total emissions of around 680Mt), etc., neutralizing any criticism of Canada's inaction on climate change on a hot political year, with 7 provincial elections and, in all likelihood, a federal one.

That is, every national ghg emissions reduction target is implicitly a position on: (a) a safe ghg atmospheric stabilization target; and (b) the nation's fair share of total global ghg emissions that will achieve safe ghg atmospheric concentrations.

Any national ghg emissions reduction is implicitly a position on a safe atmospheric ghg concentration and that nation's fair share of total global emissions that will reach that target.

According to the Tailpipe Rule, CO2 emissions due to air conditioner - related loads on automobile engines account for 3.9 % of total passenger car greenhouse gas emissions, and various technologies could reduce air conditioner - related CO2 emissions by 10 % to 30 %.51 A 30 % reduction of the 3.9 % of motor vehicle emissions associated with air conditioner engine load would decrease fuel consumption by only 1.1 %.

(1) Japan: accepted the strongest emission reduction targets, appropriately prides itself on having the most energy - efficient industry, and yet its use of coal has sharply increased, as have its total CO2 emissions.

Just a short list: — you go on and on about SMB causing a net reduction of sea level in Antarctica (and sometimes Greenland), completely ignoring that SMB is not the total ice mass balance — you routinely mentioned that human emissions aren't increasing the CO2 concentration because those emissions didn't increase for several years in a row, but concentration did.

China has indeed promised large reductions in its own carbon intensity, but these actually just means it continues on a path already set and that its total emissions would continue to grow with its economy.

Using a global model based on the marginal abatement costs of 12 countries and regions, this paper estimates the contributions of the three Kyoto flexibility mechanisms to meet the total greenhouse gas emissions reductions required of Annex 1 countries under the three trading scenarios respectively.

According to a new report from the Organization for Economic Cooperation and Development, «Economic Assessment of Biofuel Support Policies», not only is public support of biofuels costly it has little impact on reducing greenhouse gas emissions: All the tax incentives, blending targets and other public support policies in the EU, US, and Canada total $ 25 billion per year, but will ultimately result in less than a 1 % reduction in emissions from transport by 2015.

«Many scientists concede that without drastic emissions reductions by 2020, we are on the path toward a 4C rise as early as mid-century, with catastrophic consequences, including the loss of the world's coral reefs; the disappearance of major mountain glaciers; the total loss of the Arctic summer sea - ice, most of the Greenland ice - sheet and the break - up of West Antarctica; acidification and overheating of the oceans; the collapse of the Amazon rainforest; and the loss of Arctic permafrost; to name just a few.

«Let's define X as the total emissions reductions per year required... about 95 % of X has to come from behavior changes... The Windfall proponents on this blog also reject the behavior changes responsible for the 95 % Why then do they [the moderators] allow posts that recommend ignoring a component responsible for 95 % of the emissions reductions...»

In its report the IPCC emphasises the futility of subsidies for renewable energy parallel to an emissions trading system: «The addition of a CO2 reduction policy to a second policy does not necessarily lead to greater CO2 reductions,» it says in a literal translation of the IPCC's Technical Summary: «In an emissions trading scheme with a sufficiently stringent cap other measures such as subsidising renewable energy have no further influence on total CO2 emissions.»

The rebound effect — the phenomenon whereby improvements in the efficiency of energy services leads total energy use to decline and then rebound as consumers re-spend savings on increases in the same or other energy services — seriously undermines climate mitigation models that rely on efficiency for emissions reductions but ignore rebound effects.
