Industrial Pollution Calculator

Calculate the estimated pollutant discharge and greenhouse gas emissions from your industrial processes. Enter your industry type, energy consumption (kWh), fuel usage, production volume, and operating hours to get back a full breakdown of CO₂ equivalent emissions, individual pollutant loads (CO₂, CH₄, N₂O, SF₆), and a total carbon footprint in tonnes. Compare your facility's output against benchmarks and see the proportional share of each greenhouse gas.

Select the primary industrial sector for appropriate emission factors.

Frequently Asked Questions

What is CO₂ equivalent (CO₂e) and why is it used?

CO₂ equivalent (CO₂e) is a standard unit that expresses the warming potential of all greenhouse gases relative to carbon dioxide. For example, methane (CH₄) has a global warming potential (GWP) of about 28 over 100 years, so 1 tonne of CH₄ equals 28 tCO₂e. Using CO₂e allows you to compare and sum emissions from different gases on a single scale.

What is the difference between Scope 1 and Scope 2 emissions?

Scope 1 emissions are direct greenhouse gas emissions from sources owned or controlled by the facility, such as on-site fuel combustion and industrial process reactions. Scope 2 emissions are indirect emissions from the generation of purchased electricity consumed by the facility. This calculator estimates both categories to give you a complete operational footprint.

How is the grid emission factor determined?

The grid emission factor reflects the average CO₂ emitted per kilowatt-hour of electricity generated in your region, which varies depending on the local energy mix (coal, gas, renewables, nuclear). The US national average is approximately 0.386 kg CO₂/kWh. You can find your regional factor from the EPA eGRID database or your national energy authority.

Why is SF₆ treated separately from other gases?

SF₆ (sulfur hexafluoride) is an extremely potent greenhouse gas with a global warming potential of 23,500 times that of CO₂ over 100 years. Even small leaks from electrical switchgear or industrial equipment can contribute significantly to a facility's total CO₂e footprint. This calculator weights SF₆ usage by its GWP to reflect its true climate impact.

What emission factors are used for fuel combustion?

This calculator uses standard IPCC and EPA emission factors: Natural Gas ≈ 2.04 kg CO₂/litre equivalent, Diesel ≈ 2.68 kg CO₂/litre, Coal ≈ 2.42 kg CO₂/litre equivalent, Fuel Oil ≈ 2.75 kg CO₂/litre, and LPG ≈ 1.51 kg CO₂/litre. CH₄ and N₂O co-emissions are added as a small percentage of the CO₂ total based on combustion type.

How is emission intensity calculated and why does it matter?

Emission intensity is your total CO₂e divided by your annual production volume (tCO₂e per tonne of output). It measures how efficiently your facility produces goods relative to its greenhouse gas output. Tracking intensity over time helps you identify efficiency improvements even as production scales up or down.

Can this calculator be used for regulatory reporting?

This tool is designed for estimation and awareness purposes, using standardised emission factors from the EPA, IPCC, and ISO 14083:2023 methodology. For official regulatory submissions under schemes like the EU ETS, EPA GHG Reporting Program, or national carbon markets, you should use facility-specific measured data and consult a certified environmental auditor.

What steps can an industrial facility take to reduce its emissions?

Common reduction strategies include switching to renewable electricity (reduces Scope 2), improving energy efficiency through equipment upgrades, transitioning to lower-carbon fuels like natural gas from coal, fixing refrigerant and SF₆ leaks, investing in waste heat recovery, and purchasing verified carbon offsets for residual emissions. Even a 10–20% reduction in grid emission factor through on-site solar can meaningfully cut your total footprint.
