Road traffic noise reducing devices - Sustainability: Key Performance Indicators (KPIs) Declaration

This document establishes a standardized framework for declaring sustainability key performance indicators related to devices designed to reduce noise in road transportation systems. The scope of this work focuses on providing a consistent methodology for assessing and reporting environmental performance metrics across the lifecycle of such noise reduction infrastructure. By defining specific indicators, it enables stakeholders to make comparative evaluations of the ecological footprint associated with these technical solutions. The approach emphasizes transparency and data reliability in sustainability claims, ensuring that reported figures are derived from uniform calculation principles and verified procedures. This standard facilitates communication between manufacturers, regulators, and end-users regarding the environmental impacts of noise abatement technologies. It supports the broader objectives of sustainable urban planning and transportation engineering by offering a clear reference for measuring progress in noise pollution control from an ecological perspective. The guidance provided helps align product development with evolving regulatory expectations and industry best practices for environmental stewardship without imposing specific technical requirements on the devices themselves.
