Climate & Weather Simulators

Estimate your annual CO₂ emissions from electricity, car, flights, meat consumption, and heating. Compare with the Japan average (8.3 tCO₂) and the 2°C target (2 tCO₂) t…

Calculate CO2 from electricity, transport and lifestyle to set reduction targets

Calculate CO2 emissions for electricity, gas, transport & materials. Use IPCC methodology to compute your net-zero timeline with our free LCA tool.

Adjust CO2 concentration and solar constant to see their effect on Earth temperature

Calculate your personal carbon footprint with our CO₂e calculator. Compare your emissions from energy, travel, diet, and waste to the global average of 7 tonnes per year.

Built on US EPA's LandGEM (Landfill Gas Emissions Model) v3.02, this tool estimates a landfill's methane generation rate, peak year, fuel-equivalent power and CO₂-equiva…

Sum the CO₂ emissions of a product across its full life cycle, from material production to disposal and recycling. Tune the product mass, electricity grid intensity, ser…

Estimate ice accretion on overhead power lines, ship decks, wind-turbine blades and offshore structures using ISO 12494 and the Makkonen model.

From an EF rating (EF0-EF5) and debris mass, projected area and shape, compute drag, lift-off critical wind, terminal velocity, impact kinetic energy and the resulting b…

Estimate the urban heat island intensity ΔT — the extra warmth of a city centre relative to its surrounding rural area — by combining Oke's (1973) population-log formula…

Set air temperature and wind speed to calculate apparent temperature (wind chill) in real time. Check frostbite risk and use wind-speed and temperature-based wind chill …

Estimate Wind-Driven Rain (WDR) on building facades from Choi (1994).
