We are proud to have achieved Carbon Neutral Plus, having offset 125% of our emissions made in 2021 by investing in efforts to help prevent deforestation in the Amazon and help provide more efficient cookstoves in Uganda.

We have since offset 125% of our emissions from 2022 by investing in verified carbon offsetting projects helping to reduce deforestation in the Caribbean Guatemala and Mai Ndombe in Congo.  We also recently offset our 2023 emissions by investing in a project to help provide safe water in Northern Uganda and an afforestation project in Uruguay.

We believe we were the first window company in the UK to achieve Carbon Neutral Plus status.
