Combining Models? Carbon Accounting for Land Managers + Woodland Carbon Code | Vicky West

  1. 1. Combining Models?Carbon Accounting for Land Managers (CALM) + Woodland Carbon Code Dr Vicky West Forestry Commission
  2. 2. What is CALM?• Helps show carbon balance of a business as first step towards thinking about management decisions to reducing GHG emissions.• This activity-based approach for farms and estates allows businesses to focus on the activities in their own business, rather than looking at the activities of their suppliers and purchasers• CALM = Free online calculator for land managers showing the net balance between farming annual GHG emissions and carbon sequestration (soil, trees).
  3. 3. CALM - scope• Emissions of CO2, CH4 and N2O and any carbon which is stored in soil and trees.• The emissions come from: • Energy and fuel use • Livestock • Cultivation • Peat cultivation/draining • Nitrogen fertilisers and lime • Manure management • Land-use change (soil C changes)• As the farming system changes from year to year the carbon balance can be recalculated.• Based on UK GHGI LULUCF Inventory / IPCC Assumptions/Emissions Factors• Output: html, csv or pdf
  4. 4. CALM – Alternative Management OptionsImpact of Environmental Stewardship options(Applies to England – could be updated for Scotland)• Entry Level and Higher Level Stewardship incl Organic and Uplands)• Calculated as a partial budget to estimate savings on entry into Stewardship (=annual change in emission pre and post entry)
  5. 5. Combining CALM with WCCBenefit: Land manager can easily see current GHGbalance and benefit of creating woodland either •To compensate for/ reduce own NET emissions •To see volume of carbon credits to potentially sell to other companies who want to compensate for their emissionsWithin the online CALM environment:•Can see current emissions of land holding/area•Included Woodland Carbon Code carbon accountingtools for woodland creationChallenges: Comparing annual farming emission to100-year variable rate woodland sequestration
  6. 6. Questions? Dr Vicky West Accounting for Land Managers
  7. 7. DiscussionThe tools:• Do tools account for everything / is there anything missing?• Are tools fit for purpose? Where are improvements required?Combining tools:• Do we need to create an integrated carbon accounting tool for landuse? If yes: What are the aims? How to achieve them? If no: How to make land managers aware of the benefits of each tool and how/when to use each?Action:• 3 Actions we can take in next year to improve tools/accessibility of tools available to land managers• What can/should ICARB do to help in next year?
