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 for AR4, AR5 and AR6
Calculate CO₂ equivalent from CO₂, methane, nitrous oxide and common fluorinated gases using IPCC AR4, AR5 or AR6 100-year global warming potentials.
Express Shipping Carbon Footprint Calculator for Air vs Ground Delivery
Estimate CO₂e for express air parcels and standard ground shipments by weight and distance, then compare the climate impact of faster delivery against ground freight.
Wildfire Smoke Air Purifier Clearance Time & CADR Calculator
Calculate the estimated time an air purifier needs to lower indoor PM2.5 from smoke, using room dimensions, CADR, and starting and target concentrations.
U.S. EPA Air Quality Index Calculator for PM2.5, Ozone and Six Pollutants
Calculate the current U.S. EPA Air Quality Index for PM2.5, PM10, ozone, carbon monoxide, sulfur dioxide and nitrogen dioxide, with truncation, breakpoint and sub-index details.
Indoor CO₂ Buildup Calculator — Room Ventilation Estimate
Estimate how room dimensions, occupancy, ventilation, time, and starting CO₂ affect indoor CO₂ concentration and equilibrium levels.
Eco-Friendly Funeral Cost Estimator - Plan a Green Burial Budget
Estimate a green funeral budget by combining service fees, biodegradable casket or shroud costs, and burial plot prices for an eco-friendly farewell.
Gaussian Plume Dispersion Calculator - Estimate Downwind Air Pollution
Estimate downwind pollutant concentration from a stack with the Gaussian plume equation, EPA ISC3 rural and urban sigma curves, and Briggs plume rise.
