Greenhouse gas reporting

Greenhouse gas inventory

The inventory of emissions and sinks of the LULUCF sector can be divided into reporting to the UNFCCC and to the reporting under the Kyoto protocol. Land areas have been divided into areas that have remained in the current land-use and to areas that have changed since 1990 (KP) or during previous 20 years (UNFCCC).

Finnish Forest Research Institute (Metla) is responsible for quantifying land areas and land-use change for Finland. Metla also reports emissions and sinks from Forest land and from Wetlands.

Land areas

Methods

• Land areas and land use

Forest land

Methods

• Carbon stock change of biomass
• Carbon stock change of mineral soils
• Carbon stock change of drained organic soils
• Emissions from forest fires and controlled burning
• Emissions from nitrogen fertilization

Wetlands

Emissions from wetlands constitute currently only those from peat extraction sites.

Methods

• Carbon stock change of peat extraction sites

Harvested Wood Products (HWP)

Emissions and sinks from the Harvested Wood Products are reported voluntarily as an information item.

Uncertainty estimation

An important part of the GHG inventory is the uncertainty estimation of emissions and sinks. Estimates of sinks and emissions of LULUCF sector build on the National Forest Inventory (NFI) data that is a sample based assessment of forest resources.

Methods

• Uncertainty for Carbon stock and its changes in living biomass
• Uncertainty of soil carbon stock change of mineral soils
• Uncertainty of soil carbon stock change of drained organic soils
