CO₂ calculator: what does a water body emit?
Select surface area and trophic stage – the calculator shows the range of annual greenhouse-gas emissions as CO₂ equivalents. Background: worldwide, freshwater lakes release an estimated 1.3 to 2.3 Gt of carbon per year, around one fifth of the carbon released by fossil fuels.
Estimated emissions

t CO₂ equivalents per year

Avoidance potential: –
Rough estimate based on reference values from the literature – no substitute for measurement. Actual emissions depend on depth, sediment, climate and season; reliable figures come from continuous monitoring (MRV).
How does the calculator work?
The calculator multiplies the water surface area by area-specific emission factors (t CO₂ equivalents per hectare and year, GWP100) for each trophic stage. The factors are derived from the literature as ranges (including DelSontro et al. 2018): the more nutrient-rich a water body, the more methane and CO₂ are produced as organic material breaks down. The car equivalent uses a reference value of around 2 t CO₂ per car and year. All figures are orders of magnitude for context – not a substitute for a water-body-specific emissions balance.
