Universal Energy & Carbon Equivalent Converter

Convert everyday fuel purchases — LPG bottles, therms, diesel litres — into thermal kWh and Scope 1 CO₂e emissions. See exactly how much energy you are burning and what it costs the planet.

One 11 kg LPG cylinder = 152.9 kWh thermal = 32.3 kg CO₂ direct emissions. A Karnot iHEAT produces the same heat using just 34 kWh of electricity.

ESG Reporting Impact

Burning this fuel generates of Scope 1 emissions that must be reported under SEC Climate Disclosure Rules, EU CSRD/ESRS, Philippine SEC Sustainability Guidelines, and CDP/TCFD frameworks. Switching to a Karnot iHEAT eliminates this fuel from your Scope 1 reporting entirely, moving the reduced energy demand to Scope 2 (purchased electricity).

Karnot iHEAT R290 COP of 4.5 used for heat pump comparison (EN 14511 rated, hot water mode 15→60°C). CO₂e factors include combustion-only direct emissions (Scope 1). Grid electricity emission factors vary by region and are not included in this tool.

Frequently Asked Questions

How do I convert BTUs to kWh?

Multiply the BTU value by 0.000293071. For example, 100,000 BTU equals 29.31 kWh of thermal energy. This converter does it instantly and also shows you the CO₂ emissions from burning that fuel.

How much CO₂ does an 11 kg LPG cylinder produce?

One 11 kg LPG/propane cylinder contains approximately 152.9 kWh of thermal energy and produces approximately 32.34 kg of CO₂e when burned. This is a direct Scope 1 emission that must be reported under SEC, CSRD, and Philippine SEC ESG frameworks.

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

Scope 1 covers direct emissions from burning fuels on your premises (gas, diesel, LPG). Scope 2 covers indirect emissions from purchased electricity. Switching from gas/diesel heating to a heat pump moves your heating from Scope 1 to Scope 2 — and because a heat pump uses 3-5x less energy per kWh of heat, total emissions drop dramatically.

How does a heat pump reduce my carbon footprint vs LPG or diesel?

A Karnot iHEAT R290 heat pump has a COP of 4.5, meaning it produces 4.5 kWh of heat for every 1 kWh of electricity consumed. This is 3-5x more efficient than direct combustion. Additionally, it eliminates Scope 1 emissions entirely from your heating, simplifying ESG reporting.

What carbon reporting frameworks require fuel-to-CO₂ conversion?

SEC Climate Disclosure Rules (USA), CSRD/ESRS (EU), Philippine SEC Sustainability Reporting Guidelines, TCFD, CDP, and GRI 305 all require companies to report Scope 1 emissions from on-site fuel combustion. This converter helps you quantify those emissions.
