An Introduction to Woodland Carbon; A Growing Source of Funding for Woodland Creation

Woodlands can make a significant contribution to tackling climate change – in 2017 Scotland’s woodlands sequestered 9.5 million tonnes of CO₂e, reducing Scotland’s net annual emissions to 40.5 million tonnes CO₂e. 

The Climate Change (Emissions Reduction Targets) (Scotland) Act 2019 commits Scotland to have net zero greenhouse gas emissions by 2045 –  5 years earlier than the rest of the UK.  Recognising the role that woodlands and carbon sequestration have to play, Scottish Government have made the following commitments within the latest Programme for Government (2020-21):

• Increase the planting targets from 12,000 to 18,000 hectares per year by 2024-25 with increased grant funding to help with this.
• Grants of up to £20,000 for farmers and crofters to purchase new equipment through the Sustainable Agriculture Capital Grant Scheme (SACGS)

• Increase the size of the woodland carbon market by 50% in 5 years.

It is only mandatory for businesses in energy and some industrial sectors to reduce their emissions but there is a rapidly increasing desire amongst other businesses to voluntarily reduce their emissions to help meet these ambitious targets. Reaching net-zero is going to require we create more woodlands and restore our degraded peatlands.

Carbon without the jargon

Woodland and peatland – a rapidly developing carbon market

The Woodland Carbon Code (WCC), launched in 2011, is the UK’s government-backed standard for woodland carbon projects.  It applies similar standards to other global carbon initiatives but is tailored to UK conditions and legislation.  It provides the mechanism for landowners creating woodland to engage in the carbon market in the UK.  The scheme is based on robust carbon prediction tools and monitoring protocols developed by Forest Research.  New woodlands meeting the standard have to be third-party checked as being sustainably managed and meeting high carbon standards, giving confidence to buyers.

So far, over 500 woodland creation projects have registered across the UK.  More than half of these are validated by an independent validation body (Acoura or Soil Association) to check they are well set up and meet the standards set out in the WCC.   Over 90 projects so far (those set up earliest) have verified the amount of carbon sequestration after 5 years.  Over 40% of projects are in Scotland.  The registered projects across the UK will create over 20,000 hectares of woodland and are predicted to sequester almost 8 million tonnes of carbon dioxide over their lifetime (up to 100 years).

The Peatland Code, a standard managed by the International Union for Conservation of Nature (IUCN), has four peatland restoration projects validated and 13 registered in total.  The Peatland Code has similar principles to the WCC. See the IUCN website for more information.

How do you apply? 

• • • Decide whether you want to go through this process yourself, or ask a project developer to help.  If you only have one small project it’s probably easier to ask a project developer to help.  If you have a large project or are likely to go through the process more than once you might consider taking the time to learn the process and DIY. The WCC team are available to advise you.
    • Check you’re eligible and register your project on the UK Woodland Carbon Registry.  You’ll need basic information about the project/site and use that to do a carbon sequestration projection.  You need to make sure:
    • • you’re committed to permanent land use change to woodland
      • you’re registering within 6 months of the start of planting*
      • the land hasn’t been wooded for at least 25 years
      • planted areas are not deep peat (less than 50cm organic/peat layer)
      • the woodland creation is ‘additional’ – it’s not legally required, and it’s the carbon finance that will make the project viable.

• • • Complete documentation and get validated – You’ll need to complete a ‘Project Design Document’, and supply relevant information, whilst you are planning and planting your woodland, then get Acoura or Soil Association to look over your documentation.  This can’t be finished until all trees are in the ground but you have 3 years from registration to complete this process.
    • Stay Verified – at year 5 and then every 10 years, survey your site, complete  a ‘Progress Report’ and get Acoura or Soil Association to verify your documentation.  Projects can be up to 100 years long – you decide how long to commit.

*Currently you have to register within 2 years of the start of planting but deadline will soon change to 6 months.

Getting involved – costs and likely income

There are a growing number of ‘project developers’ who are willing to help landowners put their projects through the Woodland Carbon Code.  If you use a third-party project developer, they may take on some or all of the responsibility and cost of validating, monitoring and verifying the woodland carbon project over its lifetime. This leave the landowner with a smaller share of the carbon income but also less future responsibility/cost – you can decide how involved you want to be.

There’s a simpler process for small (≤5ha) projects, and projects can be ‘grouped’ for cheaper validation/verification – this needs a project developer to act as ‘group manager’.  You shouldn’t need much more information about a project than you would normally supply when applying for a woodland creation grant.  You can use our tools to work out the likely carbon sequestration of your project.

Feedback from project developers suggests corporate buyers currently pay between £7 and £20 when buying WCC units upfront – with increased demand, prices have been rising.  The majority of the volume, however, is towards the lower end of this bracket.

Table 1 shows the likely costs and income for three different scenarios: a 10ha native woodland; a group of 10 x 5ha native woodlands; 30ha of productive Sitka spruce woodland (including 25% mixed broadleaves).  Validation/verification is a fixed cost per project (~£1000 if no site visit required) whereas registry fees are volume-based (£0.09 total per carbon unit/tCO₂).  There are time and cash savings for validation/verification as a group.  Verification could cost more if site visits are required past year five (only applies to ‘risky’ projects).   For a native woodland which could generate almost 400 tCO₂/ha over 100 years, potential income from carbon credits (at £7 to 15/tCO₂) is £2,700 to 5,800/ha. Taking off the cash cost of involvement the net income could be up to £5,000/ha (at £15/tCO₂), although you still need to consider the time to undertake survey work and complete documentation.
