The Lawn and Garden Care Calculator uses the information you provide about your mower and fertilizer usage to determine emissions resulting from the care of your lawn and garden.

Please download the Community Led Emissions Reductcion (CLER) Calculator Guidance Document to learn more about how this calculator calculates CO₂ emissions.

Step 5: Provide Your Fertilizers' Nitrogen Level

Nitrogen (N), phosphorus (P), and potassium (K) are the three major nutrients needed by lawns. Nitrogen is the nutrient required most. Percent nitrogen (by weight) is always the first of three numbers on the fertilizer bag, followed by phosphorus and potassium. For example, 18-6-12 fertilizer contains 18% nitrogen.
