Ecology calculators for populations, resources, and environmental impact

Ecology calculators help quantify relationships that are otherwise difficult to compare directly. The tools cover population growth and species measures, biodiversity, forestry and land use, carbon and water footprints, waste and recycling, and resource-consumption scenarios.

Environmental estimates are especially sensitive to boundaries: a household footprint, product footprint, and full life-cycle assessment do not include the same sources. Check the geography, time period, emission factors, and system boundary behind each input, and use the result to compare scenarios rather than present it as a precise audit.
