Similar factors affect the levels of emissions of the other greenhouse gases.
Policies for addressing greenhouse gas emissions are being developed through international negotiation - the development of international environmental policy is traced in the following section. A variety of technical options are also available which could reduce emissions, especially from use of energy. These options are most easily applicable to stationary plant, which is the focus of the discussion below. Reductions in emissions of other greenhouse gases can also be achieved using technology. For example, methods of reducing methane emissions include reductions in leakage and capture of fugitive emissions, with destruction or utilisation of the methane.
