Who We Are
Between now and 2060, the world’s population will double the amount of building floor space, equivalent to building an entire New York City every month for 40 years. Much of the carbon footprint of these new buildings will take the form of embodied carbon, or the carbon emissions associated with materials throughout their lifecycle.
Effectively reducing the embodied carbon of the built environment at scale requires industry-wide awareness and action. Building Transparency was established in 2020 for just that reason.
What We Do
The building and construction sector is responsible for 40% of global greenhouse gas emissions – much of which can be attributed to embodied carbon. Building Transparency arms building industry professionals with the information they need to:
Set Achievable Carbon Reduction Targets
Our tools enable users to establish a project’s potential and realized upfront embodied carbon emissions, as well as set baselines and targets.
Identify Low-Carbon Materials
The EPD database allows users to search, filter, and compare building products and identify the best options to meet their goals.
Reduce the Sector’s Overall Impact on Climate Change
Together, our programs, tools, and resources drive widespread embodied carbon awareness and action in the public and private sectors.
Meet Our Tools
Our tools provide the actionable data and insights needed to shape a better building future by lowering the carbon footprint of the built environment. We continue to optimize the capabilities and features of both tools to support users in reducing embodied carbon emissions at scale.
EC3: Embodied Carbon in Construction Calculator
Available globally, the free, open-access EC3 tool and its underlying digitized EPD database encourage low-carbon specification and procurement to meet building and infrastructure project sustainability goals in line with the level of action needed to mitigate climate change.
tallyLCA: Empowering Data-Driven Design
tallyLCA is a whole-building life cycle assessment (LCA) tool that allows architects and engineers to see – in real-time – the impact of their design decisions on the overall carbon footprint of a project.
Join Our Mission
Widespread climate action is crucial now more than ever to reduce global embodied carbon emissions and mitigate the impacts of climate change. Our organization is possible because of the support of individuals and companies like you who believe in our mission and role in decarbonizing built spaces. Join us on our journey to build a better building future.
What Our Partners Say
“The creators of EC3 have planned ahead and, even in its inaugural stage, have provided a robust database. There are options for users to dissect and personalize their data searches. This results in an application that provides real data to make informed decisions.”
View Our Integrations
To solve our embodied carbon problem, we need an ecosystem of aligned and harmonized solutions. That’s why we work hard to support integrations with both the EC3 tool and its EPD database with leading software and solutions providers.
Explore Our Programs
Education and awareness of embodied carbon and its impact play a critical role in advancing our mission. This is why we’ve invested in and provide programs that enable more members of the building sector to join us as we drive decarbonization forward.
