The BIG Biodiversity Challenge is an initiative which aims to raise awareness of the need for biodiversity to become a key component within the construction and development industry, ensuring it becomes an integrated part of planning and projects.

Now in its tenth year, the Challenge is the number one industry initiative for raising awareness of and delivering biodiversity within construction and the built environment. Since its launch in 2013, the Challenge continues to demonstrate that, year on year, the industry excels in going that extra mile to “do one thing” to enhance biodiversity.

The BIG Biodiversity Challenge and Awards are steered by our Biodiversity Community of Practice (CoP). The CoP aims to provide a knowledge platform for biodiversity practitioners and grow support for the implementation of biodiversity net gain principles within the construction industry. This network of academia, private and public entities provides thought leadership which could lead to key guidance resources for the built environment. For more information, please contact Adrien Baudrimont.
