Methane GWP<br />
This section analyses two project types. The first type of projects mitigates<br />
global GHG emissions by capturing and destroying methane from inter alia<br />
landfills, unmanaged agricultural waste or agro-industrial waste. The second<br />
project type abates the formation of methane at source by preventing the<br />
decay of biomass or other organic residues that would have otherwise been<br />
left to decay as a result of anthropogenic activities. An energy production<br />
component may be added when the project also contributes to displacing<br />
the use of fossil fuel energy sources by producing energy through methane<br />
combustion or by supplying the gas to a natural gas network.<br />
Methodological Concept<br />
Emissions reductions attributable to methane recovery and destruction<br />
activities in year “y” are defined as:<br />
ER y<br />
= (MD project,y<br />
– MD reg,y<br />
) X GWP CH4<br />
– PE y<br />

In the case of projects reducing methane emissions through controlled<br />
combustion, preventing the decay of organic waste, emission reductions are<br />
defined as follows:<br />
ER y<br />
= (BE CH4,SWDS,y<br />
– MD reg,y<br />
X GWP CH4<br />
) – (PE y,comb<br />
+ PE y,transp<br />

Leakage is not considered, except under conditions mentioned in the analysis<br />
of AMS-III.E below.<br />
In both cases, small-scale projects shall reduce anthropogenic emissions by<br />
sources by less than 60 kilotonnes CO 2<br />
eq. annually.<br />

<strong>Methodologies</strong><br />
Projects can claim additional emission reductions if the biogas they capture is<br />
burned and used to generate electricity or heat and if it can be demonstrated<br />
that this energy generation contributes to displacing a fossil fuel based<br />
energy source.<br />
