Purpose
The feel-good page. Color-in charts make the impact visible: kilograms of CO₂ kept out of the air, the tree equivalent and the electric miles behind it, with milestones worth celebrating.

Formulas & little green wins
- Formula strip
CO₂ and tree formulas
- Notes grid
Ruled journal lines
Formulas printed on the page
- CO₂ saved (kg)
- (miles ÷ MPG × 8.89) − (kWh × grid kg/kWh)
- Trees equivalent
- CO₂ saved ÷ 21 kg per tree per year
- Grid factor
- from your utility, US average roughly 0.4 kg/kWh
Design notes
- Color-in cells instead of plotted lines: easy to fill with a highlighter or a pink pen.
- 8.89 kg is the EPA figure for the CO₂ from burning one gallon of gasoline.
- Milestone circles carry a small leaf, colored in once a goal is reached.
