5 Click to edit Master title style UNFCCC Definitions Sink - any process, activity or mechanism which removes a GHG, an aerosol or a precursor of a GHG from the atmosphere. Source - any process or activity which releases a greenhouse gas (GHG) or a precursor of a GHG into the atmosphere. Reservoir - A component or components of the climate system where a greenhouse gas or a precursor of a greenhouse gas is stored

6 Click to edit Master title style GHG inventory purpose “All practice so far for LULUCF, including 96 GL, KP, MA, 2003 GPG, and the 2006 AFOLU outline, focus on carbon stock changes (for carbon) as the measure of emissions and removals” "Clearly the purpose of emission inventories is to be able to report emissions (or removals) of gases from the atmosphere. Changes in stocks may be a way to achieve that goal, particularly in the absence of more detailed data." APPROACH METHOD

7 Click to edit Master title style Revised IPCC 1996 Guidelines Changes in forest and other woody biomass stocks may be either a source or a sink for carbon dioxide The simplest way to determine which, is by comparing annual biomass growth versus annual harvest, including the decay of forest products and slash left during harvest Harvested wood releases its carbon at rates dependent upon its method of processing and its end-use Recommended default assumption is that all carbon removed in wood and other biomass from forests is oxidised in the year of removal Not strictly accurate, but a legitimate, conservative assumption for initial calculations

11 Click to edit Master title style NGGIP advice “Parties are encouraged to report all emissions and removals of carbon to the atmosphere. Where atmospheric exchanges with biomass do not lead to a net flux (i.e. a net emission or net removal) then there is no need to report.” “Clearly there is a difference between stock changes and emissions and/or removals. Parties should report either a net emission or a net removal in the emission or removal column in the reporting tables respectively.”
