Building Green: Bio-based Construction

Building Green: Bio-based Construction

Executive Summary

Buildings are major carbon emitters. The bioeconomy offers a solution: constructing with wood, straw, and hemp. These materials don’t just reduce emissions; they turn buildings into long-term carbon storage vaults.

Key Metrics

  • 35%: Share of EU waste generation from the construction sector.
  • 40%: Potential reduction in embodied carbon and energy demand by using bio-based products.

The Challenge

Construction is resource-hungry and polluting. Traditional materials like concrete and steel have high „embodied carbon.” To reach climate goals, we need to change how we build.

The Solution

The strategy champions bio-based construction materials—timber, insulation (hemp/straw), and fibre composites.
* Standardization: Ensuring bio-based products can be fairly compared with conventional ones (e.g., fire safety standards).
* Certification: Developing a methodology to certify the carbon stored in buildings under the Carbon Removal Certification Framework.
* New European Bauhaus: Supporting demonstration projects like school renovations and social housing.

The Impact

Bio-based construction is a triple win:
1. Lower Emissions: Less energy to produce than concrete/steel.
2. Carbon Storage: Trees absorb CO2; using wood in buildings locks that carbon away for decades.
3. Regional Jobs: Supports local forestry and processing industries.
