Flexibility and power for your factors

We offer 40,000 emission factors from leading databases – and even some we've created ourselves.

The Sweep Emission Factor Database

The Sweep database, curated by our carbon experts, provides a comprehensive collection of emission factors. 

It enables businesses to precisely calculate their carbon footprint, identify emission reduction opportunities, and stay up-to-date with the latest data and research in emission estimation. 

Aside from the list below, we also embed sector-specific emission factors.

    What is the true ROI of Decarbonization?

    Emission factors are essential tools used to quantify greenhouse gas emissions associated with specific activities, operations, or products. These factors provide a standardized measurement of emissions by considering factors such as fuel type, energy consumption, and production processes. By using emission factors, companies can accurately calculate and report their carbon footprint, identify emission hotspots, and develop effective strategies to reduce their environmental impact.
