This report on "decarbonising our infrastructure" was prepared via a 3-way public/private partnership between the Civil Engineering Contractors Association (CECA) Wales, the Association for Consultancy and Engineering (ACE) and the County Surveyors Society (CSS) Cymru following our joint Annual Conference in 2021. The report sets out the challenges facing the infrastructure sector in Wales and offers a 4-theme action plan to reduce carbon impacts across the sector in Wales. Implementation of the action plan will depend on both public and private sectors working together collaboratively as part of the Welsh Construction Forum
