Construction and circular economy
Introduction
The construction industry, contributing almost 10% of EU value added and employing around 25 million people, plays a crucial economic role. However, it also has a significant environmental impact, using about half of Europe’s extracted resources and generating over a third of waste. Construction and demolition activities contribute to greenhouse gas emissions throughout the lifecycle of projects.
Given recent material shortages, the ongoing climate agenda, and the priorities of the European Green Deal, the construction sector must undergo a green and digital transition. This shift will modernize the industry, improving productivity, creating new job opportunities, and reducing environmental impact.
Aligned with the EU Industrial Strategy, the Commission is developing a transition pathway in collaboration with industry, stakeholders, and Member States. This co-created pathway will detail the scale, cost, benefits, and necessary actions for achieving the green and digital transitions, resulting in an actionable plan.
Significant legislative changes, such as revisions to the Construction Products Regulation, Energy Performance of Buildings Directive, and Energy Efficiency Directive, are also underway. The Renovation Wave strategy, aiming to double the annual rate of building renovations, will increase construction activities in the coming decade.
