This workshop brings together interested parties to consider carbon accounting tools for land use. The agenda includes discussions of tools for woodlands, agriculture, peatlands, and integrating models. The Woodland Carbon Code is a voluntary standard for woodland creation projects where carbon is accounted for. It includes standards for predicting and measuring carbon sequestration and tracking carbon credits. Over 100 projects have been registered under the Code across the UK.

1. Welcome to the ICARB
Accounting for carbon in landuse
workshop

2. Purpose
• Bring together interested parties
• Consider what tools we’ve got
• See if there’s anything missing
• Consider if we can improve what we’ve got
• See what work there is to do & think about
where we go from here
• Consider how ICARB can help

3. More integration?
Woodland Expansion Advisory Group
Report to Cabinet Secretary Richard Lochhead
Recommendation 16: Carbon calculator. Forestry
Commission Scotland should produce a simple to
use ‘carbon ready-reckoner’ which allows land
managers to identify whether –and by how much –
woodland creation could help to reduce their land
management carbon footprint.
SG response states: To be completed by June 2013.

6. What is the Woodland Carbon Code?
• Voluntary standard for woodland creation
projects where carbon is ‘counted’
• UK Forestry Standard – wider benefits
• Robust carbon measurement tools
• Transparent register
• Validation & Verification by
independent certification body
• Reassurance for investors
• Similar principles to VCS,
Gold Standard, Carbonfix
forestry.gov.uk/carboncode

7. The Code - Scope
Includes:
• Woodland creation
• Carbon sequestration and emissions within a
woodland
• Baseline, Leakage
Doesn’t include:
• Changes to management of existing
woodlands
• Carbon stored in forest products
• Substitution effects (wood products
or fuel)
• Avoided emissions of previous landuse
forestry.gov.uk/carboncode

8. Progress to date
• 104 Projects registered (45 in Scotland)
• Create 3,130 ha new woodland
• Will sequester >1.45M tCO2e over next 100 years
• Across the UK, range of soils and altitudes
• Mostly native, wide mix of species. Some conifers
• Many different owners
• 25 projects validated (18 in Scotland)
• 41% of the area
• 39% of the CO2

9. Predicting C Sequestration (1)
Account for:
• Emissions from establishment
• seedlings, ground prep (diesel), fencing, tubes, herbicide,
fertiliser, roads
• Best emissions factors available from FR
• Emissions from soil (disturbance)
• Conservative estimation agreed with Edinburgh & Aberdeen
Uni, JHI, FR
• Assume soil C loss in year 1 (up to 20% of topsoil (0-30cm)
carbon lost – f(soil type, intensity of disturbance))
• Only allow soil C gain on mineral soil previously under
arable use. More options later with improved data
• Emissions of woodland management (thinning
and clearfelling)
• Best estimates of fuel use from FR

10. Predicting C sequestration (2)
Carbon Lookup Tables
• FR’s CSORT model – pre-run for many scenarios:
• 17 species - species mapping for others
• Various spacing, yield class, mgmt (no thin, thin, clearfell)
• Accumulation of Carbon in Biomass and Debris
• Predictions validated by certification body

11. Predicting C sequestration (3)
Baseline
• Changes to biomass carbon without project
• Use IPCC Good Practice Guide LULUCF
 Any better estimates of stock/change to non-
tree biomass / non-woodland soil in UK?
Leakage
• Changes to c balance outside project area
(intensification of use or deforestation)
• UK legislation minimises likelihood
• Use IPCC Good Practice Guide LULUCF
 Any better estimates of intensification of use
of non-woodland land in UK?

14. Verifying carbon sequestration
• Projects validated at outset and verified at year 5 +
every 10 years (up to 100 years)
Carbon Assessment Protocol
• Sets out field measurement procedures to get
accurate estimate of actual sequestration
• Mensuration (tree height, diameter etc)  volume
 biomass  carbon content
• FR describe best methodologies available
• Considering remote sensing/Lidar for future
• Measurements verified by certification body
forestry.gov.uk/carboncode

15. Tracking carbon units
• Currently: Project register (with details of
carbon owners)
• By July 2013 – Markit Environmental Registry:
• Project Register
• Carbon Unit Register (Pre-Issuance Units and
Woodland Carbon Units)
• Web-based carbon unit ‘For Sale’ board
forestry.gov.uk/carboncode

16. Mandatory + Voluntary Reporting
• Mandatory reporting of GROSS GHG emissions
from April 2013 – quoted companies
• Defra GHG emissions reporting guidance for
organisations recommends showing GROSS
and NET emissions.
• Overseas offsets (Kyoto and non-Kyoto)
and Woodland Carbon Code-verified
units can be used in NET.
• Markit Registry will demonstrate
use/retiral of credits
