Proration
Proration is the automatic splitting of activity data across reporting periods when billing cycles or data records cross month or year boundaries, ensuring accurate period-level emissions totals without double-counting.
Utility billing cycles rarely align with calendar months or reporting periods. A bill covering December 15 to January 15 spans two months and potentially two reporting years. Proration splits emissions proportionally by day across the periods the bill covers.
In Gravity, proration happens automatically. The raw Activity Data export shows full records (including those extending beyond the reporting period), while reports, dashboards, and the Analyze tab display only the prorated portion within the selected date range.
This is why the Activity Data tab total may look higher than the figure on the Analyze tab: the raw tab includes full records, while the Analyze view only counts prorated portions within the selected period.
Frequently asked questions
Why does my Activity Data total differ from my Analyze tab total? +
The Activity Data export shows full records including those crossing period boundaries. The Analyze tab prorates data by day and only counts the portion within the selected reporting period. Both are correct — they represent different views of the same underlying data.

Carbon Accounting
Carbon accounting is the systematic process of measuring, recording, and reporting the greenhouse gas (GHG) emissions produced by an organization, product, or activity. It follows standardized methodologies — most commonly the GHG Protocol — to quantify emissions across Scope 1 (direct), Scope 2 (purchased energy), and Scope 3 (value chain) categories, producing an auditable inventory that underpins disclosure, reduction planning, and regulatory compliance.
