Turn buildings into a climate solution.

The Problem

Why we’re here

Building materials are responsible for approximately 11% of all global greenhouse gas emissions. For context, flights are 2.5% of global emissions.

We started Tangible because there wasn’t a good way for real estate developers and owners to manage and reduce their emissions from building materials at scale.

Why it matters

Embodied carbon is a hidden risk.

Embodied carbon can make up as much as 80-90% of a real estate developer's annual emissions. The majority of these come from extracting and manufacturing building materials, released throughout the construction process.

If you're not measuring your embodied carbon, you're not measuring your carbon.

Building codes now include embodied carbon.

Get ahead of requirements and understand your impact.
