Sustainable Construction: utilising sustainable resources, minimising waste and managing our construction activities to minimise impact and enhance the natural environment.

Community Legacy: embracing the opportunities our projects provide to engage with the community and leave a positive legacy.

Workforce Legacy and Safety: nurturing talent, diversity, inclusion and well-being across our organisation to develop a high-performing, safe and sustainable workforce that is equipped to deliver world-leading projects.

Our environmental sustainability targets: 20% reduction in Scope 1 & 2 emissions by 2025, from a 2019 base Net zero Scope 1 & 2 emissions by 2038 Net zero Scope 3 emissions by 2045 90% of project waste diverted from landfill (excl. contaminated waste) 10% of project water recycled/reused Our new Sustainable Construction playbook

We are on an ambitious decarbonisation journey and committed to our own net zero targets and those of our clients, as part of the global effort to mitigate impacts of climate change. View our new Playbook which underlines how our valued suppliers and subcontractors play a vital role in helping CPB Contractors deliver sustainable projects.

Sustainability Playbook Our net zero approach: Avoid unnecessary energy or material use Reduce emissions by using efficient and low-emission equipment Replace high-emission materials and energy with low-emission and renewable alternatives Offset emissions by purchasing carbon credits

Scope 1 emissions: primarily from fuels we consume.

Scope 2 emissions: primarily from the electricity we consume.

Scope 3 emissions: the indirect emissions associated with our activities, including material manufacturing, waste disposal, transport and travel.

Our circular economy approach: Avoid activities that generate unnecessary waste Replace raw materials with recycled alternatives Reuse and recover construction and demolition waste Recycle waste and materials
