CO2e emissions are equivalent emissions of all the greenhouse gases and particles that cause warming and converted to CO2.

There are also some contexts, however, that can require trade offs between efforts to reduce emissions of greenhouse gases and emissions of conventional air pollutants.

Greenhouse gases

While some chemical inputs generate greenhouse gases, some farmers choose alternatives, or specially treated inputs to reduce their emissions.

Agricultural sources of greenhouse gases

They represent a key tool in the fight against global warming, as their production process results in fewer greenhouse gases emissions.

The upcoming Montreal Climate Conference must take serious decisions on future actions to halt climate change, in which the largest historical producers of greenhouse gases must immediately reduce greenhouse gas emissions.

The most reasonable conclusion is that we should limit particle emissions to reduce health risks. As a consequence, the greenhouse effect would come more fully into view, which we could then hope would further strengthen the resolve to reduce emissions of CO2 and other greenhouse gases.

(c) Controlling growth in the use of fuel and power by industries through increased energy end use efficiency slows growth in the emissions of climate damaging greenhouse gases.

The certification report shall constitute a request for issuance to the Executive Board of CERs equal to the verified amount of reductions of anthropogenic emissions by sources of greenhouse gases.

In calculating the baseline net greenhouse gas removals by sinks and or actual net greenhouse gas removals by sinks, project participants may choose not to account for one or more carbon pools, and or emissions of the greenhouse gases measured in CO2 equivalents, while avoiding double counting.

Now, many of the people who participate in Earth Witness would focus on ecological problems, human caused or otherwise, especially environmental crimes and significant sources of greenhouse gases and emissions.

In 1992, the world s governments adopted the UN Framework Convention on Climate Change, promising to avoid dangerous anthropogenic human induced interference in the climate system by reducing the rate of emission of greenhouse gases, especially carbon dioxide. But, though the treaty entered into force in 1994, the rate of emissions of greenhouse gases, including CO2, has actually increased.

Twenty years ago, the world agreed to reduce sharply emissions of CO2 and other greenhouse gases, but little progress has been made. Instead, the rapid growth of the emerging economies, especially coal burning China, has caused global CO2 emissions to soar.

In the long term, emissions of CO2 and other long lived greenhouse gases constitute the main problem. But a reduction in emissions of soot (and other short lived climate pollutants) could alleviate the pressures on the climate in the coming decades.

A CDM project activity is additional if anthropogenic emissions of greenhouse gases by sources are reduced below those that would have occurred in the absence of the registered CDM project activity.

The project boundary shall encompass all anthropogenic emissions by sources of greenhouse gases under the control of the project participants that are significant and reasonably attributable to the CDM project activity.

A CDM project activity is additional if anthropogenic emissions of greenhouse gases by sources are reduced below those that would have occurred in the absence of the registered CDM project activity.

And we know that levels of greenhouse gases are rising too.

Reaffirming that anthropogenic emissions by sources and removals by sinks of greenhouse gases not controlled by the Montreal Protocol should be reported in a transparent, consistent, comparable, complete and accurate way,

The baseline for a CDM project activity is the scenario that reasonably represents the anthropogenic emissions by sources of greenhouse gases that would occur in the absence of the proposed project activity.

Leakage is defined as the net change of anthropogenic emissions by sources of greenhouse gases which occurs outside the project boundary, and which is measurable and attributable to the CDM project activity.

Leakage is defined as the net change of anthropogenic emissions by sources of greenhouse gases which occurs outside the project boundary, and which is measurable and attributable to the CDM project activity.

Five percent of our greenhouse gases are produced by mowing our lawns.

As recently as 2008, the Republican candidate for US president, Senator John McCain, had sponsored legislative proposals to use cap and trade to address emissions of carbon dioxide and other greenhouse gases.

Certification is the written assurance by the designated operational entity that, during a specified time period, a project activity achieved the reductions in anthropogenic emissions by sources of greenhouse gases as verified.

An international programme of action which was both equitable and efficient required that the world's biggest economies accepted their responsibility and undertook effective measures to substantially reduce their emissions of greenhouse gases (GHGs).

Box 1. Reduction of greenhouse gases through the use of ethanol in Brazil

What is the exact relationship between levels of greenhouse gases and planetary temperatures?

As I said, 18 percent of greenhouse gases are attributed to livestock production.

The Case for Mitigating Greenhouse Gas Emissions

H is for habitat destruction, including climate change forced by greenhouse gases.

Consistent with paragraph 18 of these reporting guidelines, each Annex I Party shall communicate a national inventory of anthropogenic emissions by sources and removals by sinks of all greenhouse gases not controlled by the Montreal Protocol.
