0 a gas that causes the greenhouse effect, especially carbon dioxide --
1 one of several gases, especially carbon dioxide, that prevent heat from the earth escaping into space, causing the greenhouse effect: --
Addressing local air pollution problems sometimes leads to lower greenhouse gas emissions as a spin-off.
These strong distributional results across countries suggest that compensation needs to be a part of the greenhouse gas policy agenda along with mitigation and adaptation.
For example, it is becoming clear that agriculture needs to be more answerable for greenhouse gas emissions.
They could be an effective intermediary between the countries that generate greenhouse gas emissions and the countries likely to be harmed.
If such a goal is to be achieved, it is the cumulative level of greenhouse gas emissions that is of importance.
In such countries, greenhouse gas emissions considerations work against policies to raise fertility, rather than providing additional arguments for reducing it.
Firstly, there are uncertainties in future greenhouse gas and aerosol emissions.
Under projected trends in greenhouse gas production, this scenario roughly approximates conditions for year 2050.
