Some accomplishments thus far..
FIA-based estimates have been gold standard for forest carbon for over a decade in the US --policy use, science community
Sustainability report, Heinz Center reports, Paper in Science (by Pacala et al.), Voluntary Reporting Program update, GHG inventories

National GHG reporting to UNFCCC
•Annual Greenhouse Gas (GHG) Emissions and Sinks (1990-present) – US EPA
•Every 5 years, summary national communication- State Dept.•USDA biennial

Guidance for GHG inventories evolves
Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas Emissions and Sinks (1994-1996)
IPCC Good Practice Guidance for Land Use, Land Use Change and Forestry (2001-2003)
2006 IPCC Revision Guidelines. Volume 4: AFOLU: Agriculture, Forestry, and Other Land Use

Primary equations
Carbon stock = area x carbon/area
CO2 change =
((Stock(t2)– Stock (t1))/(t2-t1))*3.66

Forest carbon stocks AND CO2 change (dynamics) are needed
Carbon per acre, all forest pools
Change in C over time for GHG inventories (CO2 equivalents – CO2eq)
Area of forest, change in area of forest

Flux data typically calculated at 30-minute intervals but aggregated to daily, monthly or annual values
![Page 13: A Grand Plan for FIA’s role in a FS National Carbon Accounting System](https://reader035.vdocuments.net/reader035/viewer/2022081516/56814fd6550346895dbd9a14/html5/thumbnails/13.jpg)
Measurements from intensive-site techniques are
essential--Provides interannual variability
(for a “footprint” around tower)
--Soil and forest floor flux
--Per Acre Differences

System boundaries are key
Finland story
All managed lands and related activities?
All carbon pools (above, belowground)?
Fate of forest carbon beyond the forest
–Trade (imports/exports)
–Substitution?14

National program goals for FIA
To conduct strategic forest inventories of the United States to estimate:
• extent of forest land
• volume, growth, and removal of forest resources; and
•health and condition of the forest

The FIA is basically a land based National Carbon Accounting System

Competitive advantages for FIA
We are the nation’s forest censusData on carbon stocks Focused on data and “users”Technical expertise in measurements and math
What about the science community?
![Page 21: A Grand Plan for FIA’s role in a FS National Carbon Accounting System](https://reader035.vdocuments.net/reader035/viewer/2022081516/56814fd6550346895dbd9a14/html5/thumbnails/21.jpg)
FIA and the Science Community
--FIA is in the R&D branch of the FS
--FS R&D personnel are covered under the FS Code of Scientific Ethics when conducting research
![Page 22: A Grand Plan for FIA’s role in a FS National Carbon Accounting System](https://reader035.vdocuments.net/reader035/viewer/2022081516/56814fd6550346895dbd9a14/html5/thumbnails/22.jpg)
Priority improvements
/Carbon estimates based on P3 data are documented and made available in tools and datasets
/Biomass equations -- US wide sampling for biomass data, conducted w/ utilization studies?
/Land Use-Land Cover and Change
