The concept of reducing and eventually eliminating carbon emissions from construction sites has gained significant momentum in recent years. This publication presents the most recent best practices in planning and realising emission reduction on the worksite. Decisions made during initial planning, design and procurement have a great impact on energy use and waste generation during construction. In the actual construction phase, infrastructure and industry know-how is important to facilitate use of clean energy and increasing reuse and recycling of materials. Evaluation and measurements are necessary to manage emission reductions and to build industry competence.
