How woodland creation can help

Creating new woodland is a proven way to help tackle the effects of climate change; they act as a natural ‘carbon sink’.

Trees do this by absorbing carbon dioxide from the atmosphere through their leaves, also known as carbon sequestration. Through the process of photosynthesis, trees convert this carbon dioxide by using water drawn up through their roots and the presence of sunlight to create glucose, which helps trees to grow. Oxygen is released back into the air, whilst the carbon from the glucose is locked up and stored in the tree’s roots, trunk, branches and leaves.

Eventually, once trees die and decay, some carbon will be released back into the atmosphere. Decomposing leaf litter, deadwood and other organic matter also contains carbon, which is absorbed into woodland soils. However, planting a new woodland isn’t just good for the planet, it could help your business too.

Growing a woodland could make you an income from selling official carbon units, or, with increasing demand for net zero supply chains, by helping to offset your own business’ emissions. To sell carbon units, you must register and validate your woodland and its potential carbon capture with the Woodland Carbon Code before you have planted it.

Trees sequester carbon at different rates

Conifer trees normally grow faster in their early life and therefore absorb more carbon dioxide earlier, when compared to native broadleaf woodlands. However, broadleaf woodland can store larger amounts of carbon in the long run. The same can be said when managing a woodland to provide continuous canopy cover – whereby the forest canopy is maintained without clear felling – resulting in larger amounts of carbon storage.

Young, fast-growing trees will capture carbon dioxide at a quicker rate, while mature trees can act as carbon stores for hundreds of years. Appropriate tree species and woodland management techniques are needed to realise these carbon benefits.

Woodland Carbon Code

The Woodland Carbon Code (WCC) is the quality assurance standard for UK-based woodland creation projects hoping to create carbon offsets and is internationally recognised for its high values for sustainable forestry and carbon management. The WCC generates independently verified carbon units, backed by the Government and experts within forestry and the carbon market. More information can be found on the WCC website: www.woodlandcarboncode.org.uk

It’s important to note that the WCC is not a grant and allows woodland creation projects to benefit from blended finance models, which can help to pay for the associated costs of tree planting.

You must register your woodland creation project with the WCC before planting trees. For a new woodland creation project to be validated with the WCC, it must pass associated additionality tests. This is to ensure the project would not have gone ahead without funding from carbon offsetting, or the desire to make income from that source. More information can be found on additionality by visiting: Woodland Carbon Code page.

The time to act is now

Never has there been a more important time to plant new woodland to help tackle the climate emergency. Creating new woodland is a proven way to help remove harmful greenhouse gases from the atmosphere. Financial support and expert advice are available now to support your woodland creation goals.

How the Woodland Carbon Code can benefit you

New woodland creation projects which meet WCC standards could provide an alternative income stream and cost savings:

1). Through the sale of Pending Issuance Units (PIUs) – an estimate of the future carbon dioxide the woodland will capture once the trees have grown. This can generate upfront income to help with the establishment of woodland. You can sell PIUs to companies as soon as their woodland creation project is validated. This would enable companies purchasing woodland carbon PIUs to state they are ‘working towards’ becoming carbon neutral as they are a promise of future carbon sequestration.

2). Alternatively, you can wait until the woodland has sequestered carbon to sell as verified Woodland Carbon Units (WCUs), the value of which is likely to be higher compared to PIUs as they allow companies to state their carbon neutrality.

3). ‘Growing your own’ units may save you money in future, if you plan to become carbon neutral.

At the beginning of your project you calculate the total number of PIUs your woodland is expected to sequester. Each PIU is assigned a vintage year for when the carbon is expected to be sequestered, and it can then be converted into a WCU.

Depending on your wider woodland objectives, you can still produce timber for sale if you enter your project into the WCC. However, your project must still meet additionality requirements, which takes income from timber into consideration.

There is guidance available about tax implications for woodlands. If you’re interested and want to find out more, check out our woodland owners tax guidance and speak to a financial advisor about your individual situation.

A woodland creation project validated and verified by the WCC reassures companies buying carbon units that the project is credible. The WCC is also endorsed by the International Carbon Reduction & Offset Alliance, providing greater market trust which can result in companies paying higher prices for both PIUs and WCUs.

How much income can be generated from selling carbon units?

The value of carbon units is increasing, ranging from £10 to £50+ per unit. You can decide how long you would like to commit your project to the Woodland Carbon Code, the maximum length is 100 years, and the total carbon capture is calculated across this time period.

Greater carbon capture will result in more carbon units to sell, so when designing your new woodland, consider appropriate tree species, spacing and future management activity. As an example, a native broadleaf project might expect to capture around 500 tonnes of carbon per hectare over 100 years. At £10-£50 per unit and 500 units per hectare, this could equate to between £5,000-£25,000 per hectare.

Project developers can help you validate and verify your project with the Woodland Carbon Code, and help sell your units, but have associated costs. Find out about how to sell your carbon units.

Factors that can affect carbon unit prices include:

1. The ‘vintage’ of a carbon offset can influence how much companies are willing to pay for carbon units. Each PIU has a vintage year attributed to it, to refer to the year in which that PIU will convert or is predicted to convert to a WCU. This is then checked at each verification stage to ensure that the carbon has actually been sequestered, and approval can be given for a PIU to be converted. A WCU predicted to convert in the same timeframe as a company looking to offset their carbon emissions may be considered more valuable to them than one that is not. PIUs with a vintage of 2050 or before can command a higher price, as 2050 is a popular date for carbon neutrality targets. PIUs with a later vintage may not fetch such a premium.

2. Location: some businesses looking to purchase carbon units value getting involved in the project themselves, so may be willing to pay more if the project is located near to their offices.

3. The nature of the project: some companies may have a preference on a project focussing on native broadleaf species, conifer species, or a mix.

4. Flexibility: providing public access to the woodland can increase the price companies are willing to pay for carbon units.

5. Future strategy: some companies prefer to buy before planting, while others may prefer to buy ‘off the shelf’ carbon units later down the line.

6. Associated benefits: using the WCC’s Woodland Benefits Tool, a project can be ranked (out of 5) for each of the following 4 categories: wildlife, community, water, and the economy. Some companies may be willing to pay more for units that score highly on associated benefits, if they value the importance of these wider benefits.

The sale of PIUs and WCUs can take place at the same time and can include a mix of the two. They can be sold any time and to any company looking to offset UK carbon emissions.

England Woodland Creation Offer

Our flagship England Woodland Creation Offer supports new woodland creation by covering standard capital costs up to £10,200/ha, providing annual maintenance costs of £350/ha for 10 years, with additional contributions available up to £8,000/ha when delivering wider benefits to society, nature recovery, and the environment. Applicants can also retain Basic Payment Scheme payments and receive a contribution towards the costs of access infrastructure.

How to generate carbon units through the Woodland Carbon Code

Before planting trees, you must register your woodland creation project with the WCC. Thereafter, you can follow the steps laid out below to generate carbon units. Within 3 years the woodland must be validated to generate and list PIUs. A verification assessment is needed in year 5 and again by year 15 to convert PIUs to WCUs.

The WCC provides guidance on how to validate and verify your woodland project. The Organic Farmers and Growers or Soil Association are both accredited by the UK Accreditation Service to provide this independent service for Woodland Carbon Code projects.

The Woodland Carbon Guarantee

The Woodland Carbon Guarantee (WCaG) ensures long term certainty for landowners and farmers, providing a guaranteed price for their Woodland Carbon Units (WCUs) to make it a worthwhile investment. Having a guaranteed price, alongside index-linking, reduces the financial risk that is often associated with a long-term investment.

The WCaG is an incentive aimed at helping accelerate woodland creation that is clearly targeted at the removal of carbon dioxide from the atmosphere. Projects registered with the WCC and holding a valid WCaG contract can sell their verified WCUs to the government for a guaranteed price that is indexlinked for the life of the project contract, every 5 or 10 years up to 2055/56. However, to allow you flexibility and the ability to make income from a rising market, you can still choose to sell your carbon units on the open market as PIUs or WCUs at any point in time, you just need to tell the government that you are not going to sell to them. The WCaG is available in addition to the England Woodland Creation Offer.

The Woodland Carbon Guarantee: 5 stages to selling carbon units

1. Pre-application: discovering more about the WCC and WCaG and project funding gaps can help you to understand if it will be financially viable before investing time and effort into the design process. Remember carbon funding from either the private market or the WCaG can help bridge those funding gaps and provide good evidence of potential additionality. Consider if you want to apply for a government grant to help create your woodland, as this will have implications for your bid at auction.

2. Application: if the project looks viable with the addition of ‘carbon funding’ then you will need to register it through the Woodland Carbon Code website. Having calculated how much carbon your woodland will sequester, using the WCC carbon calculation spreadsheet, you can then submit a Woodland Carbon Guarantee application form.

3. Auction: upon acceptance of your application, you will be invited to take part in an online auction which takes place approximately twice a year. Auctions are used to agree the price of WCUs to be sold to the government. Participants are asked to submit their lowest price in a sealed bid process. It is a competitive auction, and only the lowest bids will be successful. A reserve price is set by government, which is the upper limit for successful bids at auction. Successful bids will receive a conditional offer.

4. Validation: only once you receive a conditional contract offer post-auction can you begin to plant your woodland, which then must be validated under the WCC.

5. Verification and sale of carbon: you’ll need to verify your woodland carbon estimates every 5 or 10 years through the WCC to confirm the amount of carbon sequestered and the number of WCUs you will deliver through your woodland creation project. All government contracts will expire in 2056, and any units not verified before then will need to be sold to the private market, or used for offsetting your own emissions.
