8 - ACCESSALL

To develop sustainable maintenance methods and strategies for urban paved areas to ensure year-round accessibility of all users and economic sustainability, while reducing CO₂ emissions. This takes into account that today municipalities in cold climates struggle to reach their CO₂ emissions targets, within their economical constrains, without sacrificing accessibility and safety for all users.

• Task 8.1: identify existing literature and common practices in winter maintenance and mobility requirements for all users.
• Task 8.2: develop an analytical framework to evaluate the sustainability of existing winter maintenance practices. The framework details the three dimensions of sustainability. Social sustainability will be expressed by quantifying accessibility and safety of all users; environmental sustainability considers emissions of greenhouse gasses, chlorides and dust; economic sustainability is expressed by costs increase.
• Task 8.3: develop CO₂-budget based scenarios for winter maintenance, which specify how much maintenance can be done for a given CO₂ emission and cost (investment&operational), and what the expected consequences are for the accessibility and safety of all users.
• Task 8.4: apply the developed framework to evaluate the sustainability of winter maintenance of selected real scale urban scenarios at two specific project locations: Trondheim, Norway and Stockholm, Sweden.

• Guidelines on how to achieve CO₂ emission reduction in maintenance of urban paved areas without compromising the accessibility of vulnerable users.
• Analytical framework to evaluate CO₂-reducing strategies in urban winter maintenance from a holistic sustainability perspective.
• Demonstration of how CO₂ emission reduction can be reached for urban winter maintenance without sacrificing accessibility of users within reasonable budgets.
