Our measures

How do we track our performance and guide improvement?

In order to ensure we provide a high quality collection service, save resources, and provide jobs and training, we keep a close eye on a range of measures. Some things we can measure directly, some things need to be defined in order to pin down a number, and some things we have to estimate. You can learn more about how we do this below.

0 cubic yards of wood collected*

*Measures complete to the end of March 2022

0% reused as timber
0% reused as firewood

Reuse and recycling

The reuse suitability of the wood in each load is determined either when the collection is made or when the wood is sorted back at the enterprise. This information is reported on our collection summaries and social and environmental impact reports.

0 tonnes CO2e saved
0 gallons of fuel saved

Greenhouse gas reduction

Various gasses contribute to climate change, for instance methane is over 80 times more damaging than carbon dioxide by weight. This is why greenhouse gas impacts are usually given in terms of carbon dioxide equivalent (CO2e). We calculate the reduction in emissions represented by our activity based on 3 key differences to our competitors:

All together, this means we estimate that for every tonne of wood we collect and reuse, the equivalent of about half a tonne of CO2 is saved.

Due to the difficulty of getting accurate figures, this estimate doesn’t take into account the impacts of diverting from the recycling stream to the reuse stream (the energy and transport costs of recycling can be significant), the implications of deforestation and illegal timber in the wood supply chain, or the impacts of burning wood for fuel, which releases a lot of CO2 but displaces more polluting fossil fuels. For more information about the wood economy, see Recycling Wood in the UK.

Jobs and training

To ensure we keep meeting our objective of changing lives, we record how many people work and volunteer in the network each month.

To help our clients demonstrate the social benefit of using our service, we supply Social and Environmental Impact Reports that estimate the impact of their contribution, given in terms of the proportion of our trade they contribute. For example, if in a given year we provided 300 years of work and 1000 days of training, a company that contributed 10% of the total wood collected in that year would be attributed 10% of those outcomes on its report – 30 years of work and 100 days of training. This represents the opportunities created directly by the collections and collection income, as well as subsequent processing and sale of the wood.
