Crutzen and colleagues were the first to assess biomass burning as a source of gases and particulates to the atmosphere (Crutzen et al., 1979; and Seiler and Crutzen, 1980). How

This chapter begins with a brief overview of how CH. is generated from the anaerobic decomposition of waste and then discusses generation of CH. in detail in landfills, was

This increasing concentration of methane (CH.) in the atmosphere is of particular concern because of the potential effects that it can have on global atmospheric chemistry and climate. Given its relatively long atmospheric lifetime, methane emissions do not appear, in general, to ha

This paper will explore explanations for the observed variation and provide estimates of total emissions. Emphasis will be placed on ruminants which account for approximately 95% of animal methane emissions.

A summary and discussion of available global and country-specific emission estimates are also provided. Where possible, assessments of data quality are offered.
