Every tonne you've already cut counts.
Put solar, a heat pump or an EV on your timeline with the date you did it. See the tonnes and dollars each one has saved since, counted against your province's grid in every year.
Start with what you've already done.
Rough answers are fine to begin with. You can sharpen them later with bills and logged trips.

One person's share of a two-person home. Each year is counted against Alberta's grid for that year.
About 2 elephants
8.8 t is about 2 elephants, at five tonnes an elephant. Which raises a better question: how do you move an elephant to a new zoo?
