How to estimate your farm's carbon footprint
Your cultivation carbon footprint is the greenhouse gases released growing a crop in one season — mostly from fertilizer manufacture and the nitrous oxide soils give off after nitrogen is applied, plus fuel, electricity, liming, and any residue burning. This free calculator estimates it from the inputs you enter, using published emission factors, and shows you where your emissions come from.
What's included — and what isn't
The estimate covers the cultivation cycle: nitrogen, phosphate, and potash manufacture; direct and indirect soil nitrous oxide; diesel for field operations; electricity for pumping; liming; crop-residue burning; and pesticide manufacture. It excludes land-use change, soil-carbon sequestration, machinery manufacture, transport, and post-harvest stages — so read it as a cultivation-stage estimate, not a whole-farm life-cycle assessment.
Where the numbers come from
Each source is your entered quantity times a published emission factor: IPCC Tier-1 factors for soil nitrous oxide, liming, and residue burning; Fertilizers Europe values for fertilizer production; the UK DEFRA 2024 factor for diesel; and the IEA global average for electricity. Global warming potentials use the IPCC AR5 100-year basis. Because production and grid factors vary by region, treat the result as a planning estimate — for certification, follow a recognized protocol such as ISO 14064 or the GHG Protocol.
Pair it with the fertilizer calculator to right-size nutrient inputs, or the profit calculator to weigh inputs against margin.
