Tree Planting

November, 2019|

Choosing to build using the PH15 System makes a substantial impact on the amount of carbon emitted compared to building in masonry. A typical PH15 house can emit less than a third of the same sized masonry building* and we are working hard to get this down further.
We source our timber from Poland where over 30% of the country is covered by sustainably managed forests. We use quick growing, low grade timber, that will soon be replaced with new trees. Trees help to clean our air, reduce flood risk, provide homes for wildlife, store carbon, as well as being proven to boost our own health & wellbeing.
UK forests only cover 13% of our land area. We now urgently need to plant trees (the estimated need is 1.5 billion new trees by 2050 to become carbon neutral) and we should revitalise our timber industry too. To contribute to this aim we now fund the planting of new woodland for every PH15 project. This is being done in conjunction with The Woodland Trust.
