I Built a Carbon Calculator Where the Emission Factor Doesn't Exist

Jun 3, 2026 · 5:37 AM UTC ·5 min read · 0 reactions · 0 comments · 39 views

TL;DR · WeSearch summary

The article discusses the development of a carbon calculator specifically for refrigerant emissions, which differs from traditional calculators that rely on fixed emission factors. It highlights the complexity of using Global Warming Potential (GWP) values that can change over time, requiring careful consideration in data modeling. The author emphasizes the importance of transparency in presenting emissions data to users, especially when different GWP values may lead to significant discrepancies in calculations.

Key facts

▪Most emissions calculators use fixed emission factors from a lookup table.
▪Refrigerant emissions calculations rely on the Global Warming Potential of the gas, which can vary based on the reporting context.
▪The author refactored the calculator to ensure users are informed about changes in GWP values that could affect their emissions calculations.
