They also contribute least to the global emissions of greenhouse gases.

This year, China will surpass the US in emissions of greenhouse gases.

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

Greenhouse gases

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

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.

Agricultural sources of greenhouse gases

Climate scientists have warned for years that global warming caused by manmade emissions of greenhouse gases will generate more extreme storms.

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

Twenty years ago, the world agreed to reduce sharply emissions of CO2 and other greenhouse gases, but little progress has been made.

We must face the facts our emissions of greenhouse gases probably are at least partly to blame for this summer of extremes.

People are still figuring out what a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases actually means.

With carbon dioxide emissions in 2010 of 6,494,000 tonnes, Ethiopia contributes just 0.02 to the annual human caused release of greenhouse gases.

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.

We should be open to other ways to stop warming such as cutting carbon emissions in the future instead of now, or focusing on reducing emissions of other greenhouse gases.

European economies will face lower costs in limiting emissions of greenhouse gases from energy use, leading to more effective control of climate change.

Furthermore, methane biogas has been tested to prove that it can reduce 99 million metric tons of greenhouse gas emissions or about 4 of the greenhouse gases produced by the United States.

One possibility is to establish climate neutrality as a long term global objective i.e., work to reduce net emissions of greenhouse gases to zero.

We know that the amount of greenhouse gases is rising due to our emissions, and we know that this is causing warming. But how much?

Naturally, measures targeting soot and other short lived particles must not undermine efforts to reduce CO2 emissions. In the long term, emissions of CO2 and other long lived greenhouse gases constitute the main problem.

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.

Despite the IPCC s target for annual per capita CO2 emissions, we still do not know how much warming various levels of greenhouse gases in the atmosphere will cause.

(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.

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.

The authors note that 18 years of the Kyoto Protocol approach to international climate policy have failed to produce any discernable real world reductions in emissions of greenhouse gases.

Greenhouse gas emissions are the archetypal case.

The Case for Mitigating Greenhouse Gas Emissions

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.

The choices, singly or in combination, are 1) nothing (the current response) 2) mitigation (reducing emissions of greenhouse gases) 3) attempted adaptation to the ongoing climate changes and 4) geoengineering.

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.

We know from measurements that greenhouse gases are accumulating in Earth s atmosphere.

Urgent action is needed both to adapt to the climate change that is inevitable and to reduce emissions of greenhouse gases, especially CO2, to prevent further damage as far as possible.

These calculations indicate that a Blueprints world with CO2 capture and storage results in the least amount of climate change, provided emissions of other major manmade greenhouse gases are similarly reduced.

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,

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.

The atmosphere is filling with greenhouse gases from heavy use of fossil fuels.

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

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.

Publicly acknowledging that the US has been the largest historic emitter of greenhouse gases, she declared that the America must lead efforts to cut harmful emissions and build a lower carbon economy.

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.

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.

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.
