Carbon Calculation Report
Your hempcrete walls store real carbon. This tool calculates exactly how much: sequestered CO₂, net carbon balance, avoided emissions versus conventional construction. The output is a formal Carbon Calculation Report prepared by a qualified engineer, accepted by banks for green finance applications, councils for green building submissions, and ESG auditors for sustainability reporting. Your client may use it to pursue carbon credits or green mortgage benefits.

Calculate. Capture. Climate Positive.
Your hempcrete walls store real carbon. Now you can prove it, and get paid for it.
Every kilogram of hemp hurd embedded in your walls has absorbed CO₂ from the atmosphere during the plant's growth. That carbon is now locked permanently in the building. This is not a claim. It is a measurable, quantifiable, engineering-verified fact.
This Carbon Calculation Report tells you exactly how much CO₂ your project stores, what it avoids compared to conventional construction, and what that means in financial terms. Banks offering green finance products need this data. Councils processing green building applications accept it. ESG auditors use it for sustainability reporting. And your client may use it to pursue voluntary carbon credits through registered markets.
Enter your project parameters below. The calculator runs instantly. The formal report is prepared by a qualified Civil and Environmental Engineer and delivered within 48 hours.
Emission Factors (peer-reviewed): Hemp hurd sequestration: 1.80 kg CO₂e per kg (Arehart et al. 2020, Journal of Cleaner Production; Pervaiz 2003) | Hydraulic lime embodied carbon: 0.90 kg CO₂e per kg (EuLA 2019 / IPCC 2006) | Conventional wall reference: 120 kg CO₂e per m³ (ICE Database v3.0, Bath University)

Methodology: Hemp hurd sequestration: 1.80 kg CO₂e/kg (Arehart et al. 2020; Pervaiz 2003). Hemp hurd density: 110 kg/m³. Hydraulic lime: 0.90 kg CO₂e/kg (EuLA 2019). Transport: 0.10 kg CO₂e/tonne-km. Conventional reference: 120 kg CO₂e/m³ clay brick (ICE Database v3.0). This is an indicative engineering estimate. It does not constitute a certified Life Cycle Assessment. For formal green finance, council, or ESG submissions, a Carbon Calculation Report prepared by a qualified engineer is required.
