Framework for carbon emission evaluation of road maintenance

In the United Kingdom, carbon emissions associated with business activities have shifted from matters of policy to sources of legal responsibilities under the Climate Change Act of 2008. A flexible and easy-to-use technique is needed so that businesses can assess their carbon emissions in response to regulations on the environmental impact of construction activities. The aim of this study was to develop a methodology that could offer businesses a carbon life-cycle assessment tool to identify emissions hot spots across the value chain and inform a carbon-reduction hierarchy. The approach employed was based on methodology described in the publicly available specification (PAS2050) protocol. The objective was to identify locations where the largest production of emissions occurred and provide for the biggest potential reduction within routine highway maintenance processes. The methodology framework allows businesses to make informed decisions in carbon terms through the identification and prioritization of areas of potential reduction of emissions.
