Enhancing Emissions Accuracy with Activity Inputs
Last updated: November 27, 2025
Coolset uses a hybrid approach to calculate carbon emissions by combining financial data with activity inputs. This method improves accuracy and gives a more detailed view of your company’s environmental impact. Understanding how and when to use activity inputs can help you make smarter sustainability decisions.

What are activity inputs?
Activity inputs are specific, measurable data points about your operations that influence your carbon emissions. Unlike financial data, which offers a general overview (e.g., how much you spent on fuel), activity inputs focus on the actual quantities and types of activities—like:
Liters of fuel used
Kilometers traveled
Kilograms of material purchased
This detail enables more precise carbon calculations.
Common types of activity inputs
The types of activity inputs you collect depend on your operations. Here are common categories:
1. Logistics & transportation
Mode of transport (air, road, sea)
Fuel type
Distance traveled (in kilometers)
Load efficiency
2. Energy consumption
Electricity, gas, or other fuels used in your facilities
3. Waste management
Volume and types of waste
Disposal methods (recycled, landfilled, etc.)
4. Supply chain operations
Resource usage in supplier processes (e.g., steel, wood, paper, plastic)
When should you use activity inputs?
Use activity inputs when:
You have access to reliable, detailed operational data
Your business has direct control over logistics, energy use, waste, or supply chain activities
Getting started
If you already know which areas of your business have the highest carbon impact, begin collecting activity inputs there.
If you're unsure, start with a spend-based method to identify high-impact categories, then layer in activity data for more precision.
