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.

      Notes grid

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.
