Climate & Sustainability Calculators
Measure carbon footprints and emissions, compare waste and recycling choices, and model climate effects from sea level rise to urban heat and air quality.
Top calculators
A short starting set for the most common climate & sustainability calculators workflows.
Landfill Methane Emissions Calculator - First-Order Decay Model
Estimate annual and cumulative methane generation from landfilled waste using a first-order decay approach.
Greenhouse Gas CO₂e Calculator | Convert CO₂, CH₄, and N₂O to CO₂e
Convert carbon dioxide, methane, and nitrous oxide masses into total CO₂ equivalent using 100-year global warming potentials, with a clear formula, worked example, interpretation guide, and an optional CO₂e sorting mini-game.
Indoor CO2 Buildup Calculator - Estimate Ventilation Needs
Predict indoor carbon dioxide concentration based on room size, occupancy, and air changes per hour.
Express Shipping Carbon Footprint Calculator
Estimate and compare the carbon footprint of express air shipping versus standard ground delivery. Enter package weight, distance, and shipping mode to see C...
Air Quality Index Calculator - Understand Pollution Levels
Estimate U.S. AQI from PM2.5, PM10, and 8-hour ozone concentrations. See pollutant sub-indexes, the dominant pollutant, and health guidance.
Air Purifier Smoke Clearance Time Calculator
Estimate how long an air purifier needs to clear wildfire smoke particles from a room based on CADR and room volume.
Eco-Friendly Funeral Cost Estimator - Compare Green Options
Estimate the costs of a green burial or eco-friendly funeral service compared to a conventional ceremony.
Gaussian Plume Dispersion Calculator - Estimate Downwind Air Pollution
Estimate downwind air pollutant concentration from a continuous point source with a simplified Gaussian plume model, stability classes, and an optional plume-mapping mini-game.
