1 the European Commission's in-house science service Serving society Stimulating innovation Supporting legislation Forest biomass assessment and flows Nicolas Robert, Roberto Pilli, Ragnar Jonsson, Noemi E. Cazzaniga, Giulia Fiorese, Francesca Rinadi, Sarah Mubareka, Viorel Blujdea, Daniele Palermo, Andrea Camia Biomass workshop organized by Stockholm, 13 June 2017

2 Forest biomass: harmonization needed top Differences Forest definition Area surveyed by NFIs Criteria for Forest Available for Wood Supply (FAWS) Minimum DBH Tree components measured Definition and methods for NAI estimation NFI reference years Forest and other wooded land Forest Forest Available for Wood Supply (FAWS) 182 Mha 161 Mha 134 Mha stump Trees outside forest leaves branches stem 2

3 Forest biomass assessment: method Parameterization Forest resource model (CBM) Model runs Harvest (UNECE EUROSTAT) Forest resources / NFI data Forest resources in 2013 By country Various definitions and dates EU forest resources Harmonization Biomass harmonization factors FAO / UNECE Forest Europe Cross-check EU forest resources in 2013 Basis for EU projection of EU forest biomass resources 3

4 Forest biomass assessment: stock EU28 Estimates in 2013 from the Biomass study All forest FAWS EU Mt Mm 3 Mt Mm 3 Stemwood 12,678 27,295 10,862 23,405 OWC 5,889 12,593 5,063 10,841 Total AGB 18,567 39,888 15,925 34,246 EU28 Estimates from SOEF 2015 (same as ESTAT 2016) Forest All forest FAWS Area (Mha) Growing stock (Mm 3 ) 26,526 23,100 4

6 Forest biomass assessment: gaps Lack of harmonized definition of Forest available for wood supply Biomass harmonization factors missing for some countries Lack of spatial dimension Linkage to harvested wood quantities 6
