Edité par CCSD ; INRA-ADEME -
The study is divided into two main sections:Part 1 summarizes the environmental, health, technical and statutory issues concerning emissions from livestock farming. It also describes the emission processes of the gases concerned.Part 2 presents the various methods that have been developed and implemented by members of the RMT network to measure emissions of greenhouse gases, ammonia and nitrogen oxides. The methods cover all measurement stages, from taking air samples to analyzing pollutant levels, for livestock buildings, manure storage and fields. For each method, an application note describes the principles and implementation of the method, the sources of uncertainty and the main advantages and limitations. These advantages and limitations are then summarized in a table which is followed by a guide to selecting a method depending on whether it is to be used for can be used for research, improving production processes or meeting regulatory requirements. This part ends with a discussion of the uncertainties related to the measurement of emissions and gives an example of evaluating uncertainties for a particular case.Finally, the study looks at the outlook for research in the field and gives a glossary defining certain terms and acronyms used.
