Reducing Embodied Carbon in Buildings
Opportunities from Innovation - Concrete
Ultra-efficient, connected buildings combine high performance and low-carbon buildings materials with electric systems, distributed energy and intelligent management systems to maximize efficiency.
Buildings account for at least 40 percent of energy-related global carbon emissions on an annual basis. At least one-quarter of these emissions result from embodied carbon, or the greenhouse gas (GHG) emissions associated with manufacturing, transportation, installation, maintenance, and disposal of building materials. Embodied carbon reductions can often:
- Reduce material use and project costs,
- Reduce energy consumption in raw material extraction, manufacturing, and transportation,
- Help to meet green building certification requirements, and
- Better position building owners for future code or policy changes that incentivize or require low embodied carbon.
A sustainable, zero-carbon global economy will, literally and figuratively, rest on concrete. It is the world’s most-used building material. It is ubiquitous, versatile, affordable, durable, strong and recyclable – and is the second-most consumed substance in the world, after water. It will provide the foundations for our green energy systems, for climate-resilient infrastructure, for safe, healthy, and secure housing, for clean water and for low-carbon transportation around the world. It will be central to meeting many of the world’s Sustainable Development Goals.
