How will the emissions trading mechanism for greenhouse gases work?
FREQUENTLY ASKED QUESTIONSFirms that have an emission intensity lower than their targets will receive credits that could be sold to those who are unable to meet their obligations. Credits could also be "banked" for future use. Firms that have an emission intensity that is above their target could use credits from previous years, or purchase credits from other firms that have a surplus.
Related QuestionsHow will the emissions trading mechanism for air pollutants work?
FREQUENTLY ASKED QUESTIONSA Canada-wide trading system will be introduced for emissions of sulphur oxides (SOx) and nitrogen oxides (NOx). The rules for this trading system will be determined as the regulations are developed. Trading will be restricted in areas that have poor air quality to help maintain a minimum level of local or regional air quality. Canada will pursue linking its domestic sulphur oxides (SOx) and nitrogen oxides (NOx) emissions trading system with the existing U.S. system.

Global Warming: Frequently Asked Questionsa car with its windows rolled up on a sunny day keeps the sun's warmth inside the car, carbon dioxide or any other greenhouse gas has the ability to prevent the reflection of solar radiation back out into space. The greenhouse effect is a natural phenomenon. It is the reason our day and night temperature differences are so narrow.
Related QuestionsWhere do greenhouse gases come from?
ETF FAQsGreenhouse gases are emitted from a variety of natural and anthropogenic (human) sources. Carbon dioxide has the greatest effect on climate change because of its abundance. CO2 is emitted from the burning of fossil fuels (coal, oil, and natural gas), solid waste incineration, and wood burning (deforestation). Only a small proportion of CO2 emissions come from natural sources, such as plant decay, volcanic eruptions, and animal respiration (BBC 2004).
Related QuestionsWhat are greenhouse gas (ghg) emissions?
ETF FAQsGreenhouse gas emissions are gases that trap heat in the Earth's atmosphere. Without greenhouse gases the average global temperature would go from 59 degrees Fahrenheit to 0 degrees Fahrenheit. The most notable greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), halocarbons that contain fluorine such as hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) (EPA 2003c). Each greenhouse gas differs in its ability to hold heat.
Related QuestionsWhy is there concern about greenhouse gas emissions?
ETF FAQsScientists know for certain that human activities are changing the composition of Earth's atmosphere. Increasing levels of greenhouse gases, like carbon dioxide (CO2 ), in the atmosphere since pre-industrial times have been well documented. There is no doubt this atmospheric buildup of carbon dioxide and other greenhouse gases is largely the result of human activities. It's well accepted by scientists that greenhouse gases trap heat in the Earth's atmosphere and tend to warm the planet.
Related QuestionsCan we prevent climate change by reducing emissions of greenhouse gases?
FAQs - SWCCIP - Our South WestExperiments run on global climate models show us that when we reduce emissions of carbon dioxide, we reduce the rate of rise of average global temperatures and so lessen the rate and impacts of climate change. We can therefore slow the rate of warming by changing our behaviour. However, once released into the atmosphere, carbon dioxide remains there for about 100 years.
Related QuestionsGreenhouse: questions and answersAtmospheric trace gases that keep the Earth’s surface warm are known as greenhouse gases. About three-quarters of the natural greenhouse effect is due to water vapour. The next most significant greenhouse gas is carbon dioxide.

FAQs - SWCCIP - Our South WestGreenhouse gases are gases in the atmosphere that have the capacity to absorb long-wave radiation emanating from the Earth's surface. By absorbing this energy and re-radiating it, the gases cause the temperature of the Earth's lower atmosphere and surface to increase. The most common greenhouse gases are water vapour and carbon dioxide. Back to topRelated Questions
David Suzuki Foundation: Climate Change: FAQsGreenhouse gases trap heat in the earth's atmosphere. Without these gases, the earth's temperature would not support the variety of life on this planet. But when we burn large amounts of fossil fuels such as oil, coal and gas, we are dramatically increasing the atmospheric concentration of these gases. Like the glass in a greenhouse, this raises the average air temperature in the lower atmosphere. More energy is retained as heat or manifested as increased atmospheric activity.Related Questions

Frequently asked questions about climate changeThe main greenhouse gases are water vapour, carbon dioxide, methane and nitrous oxide. They are called greenhouse gases because their role in the atmosphere is like the glass of a greenhouse (or a blanket), trapping heat. Without this protection the earth would be too cold for life. The concentration of greenhouse gases in the atmosphere is changing because of human activities.Related Questions
Carbon Reduction Fund | Frequently Asked QuestionsEach greenhouse gas (GHG) has a different effect on global warming; however, it is most convenient to refer to the combination of gases in terms of Carbon Dioxide Equivalence (CO2e). Each gas has a different global warming potential, or GWP score which determines its relative strength in producing global warming effects, with CO2 having a score of 1. The GWP for Methane, for example is 23, making it 23 times as potent as CO2.Related Questions
middot; What will happen to Earth's climate if emissions of these greenhouse gases continue to rise?
ESRL Global Monitoring Division - FAQ'sBecause human emissions of CO2 and other greenhouse gases continue to climb, and because they remain in the atmosphere for decades to centuries (depending on the gas), we're committing ourselves to a warmer climate in the future. The IPCC projects an average global temperature increase of 2-6°F by 2100, and greater warming there after. Temperatures in some parts of the globe (e.g., the polar regions) are expected to rise even faster.

By using the otherwise wasted methane contained in the collected landfill gas to generate electricity or directly as a fuel, fossil fuels such as oil and coal are displaced.
Related QuestionsQuestion: What greenhouse gas emissions are associated with natural gas in the U.S.?
Natural Gas FAQs - Energy Information AdministrationNatural gas is primarily methane, which is a major greenhouse gas. Methane is emitted directly to the atmosphere from sources such as leaks in natural gas wells and pipelines and is produced in landfills, sewage treatment facilities and livestock operations. Other major greenhouse gases, carbon dioxide and nitrous oxides are produced when natural gas is burned for heating and electric power production.
Related QuestionsWhat is emissions trading?
Climate Change FAQ 4-Emission Trading vs RegistriesEmissions trading is the transfer in ownership of emission credits. The most common type of emissions trading program is called cap and trade. This scheme places a cap on emissions for a group of sources that becomes the highest limit for the group. Each source within the group is allotted a certain fraction of the total emissions. Entities that intend to exceed the prescribed limits may buy emissions credits from entities that are likely not to exceed their limits.

FREQUENTLY ASKED QUESTIONSOur targets are ambitious enough to lead to absolute reductions in emissions as early as 2010 and no later than 2012, not just reductions per unit of production. All our action announced to date to tackle climate change, including these industrial targets, will put us on the path to absolute reduction in Canada's greenhouse gases by 20% by 2020 compared to 2006 levels.
Related QuestionsYou only mention CO2. What about the other greenhouse gases?
Climat Mundi - Basic FAQsIt is simpler just to talk about CO2, but of course there are the other greenhouse gases such as methane (CH4), nitrous oxide (N2O), the hydro fluorocarbons (HFC), and sulphur hexafluoride (SF6). We include them in our calculations as "CO2 equivalents". Thus 1 ton of methane (whose heat-trapping qualities are 20 times more powerful than those of CO2) is equivalent to 20 tons of CO2. However, we have chosen to simplify even further on this website and only talk about CO2.
