Calor BioLPG

Is BioLPG is Renewable and Sustainable?

Calor BioLPG is purchased and supplied in accordance with the European Union Renewable energy directive and the relevant local renewable schemes. In order to demonstrate compliance in meeting this standard, Calor appointed external auditors to verify our supply of BioLPG, these audits are carried out throughout the year.

([1]The Renewable Energy Directive (RED) is a regulation put in place to set out renewable targets, suitable methods to achieve these targets and how to demonstrate compliance. One way for companies to demonstrate that their biofuels comply with the criteria is to participate in voluntary schemes that have been recognised by the European Commission.

Voluntary schemes verify compliance with the EU's biofuels sustainability criteria. The whole production chain from the farmer growing the feedstock up to the biofuel producer or trader is checked by independent auditors.

ISCC ( is listed first in the RED approved scheme list ( and is the one currently governing Calor's BioLPG supply. Our producers and suppliers of BioLPG are certified under the ISCC scheme.

ISCC certificates are supplied to Calor in accordance with the scheme rules, these certificates list a unique identification number which can be traced back to ISCC, the Geographic origin of renewable resource and the technology process used to produce the biofuel.

What are Calor BioLPG Carbon Emission Savings based on?

Calor BioLPG is certified under the ISCC Proof of sustainability certificates. The scheme uses actual carbon emission values for each stage of the production and supply process, to calculate a carbon value associated with using the fuel per Megajoule or Kilowatt.

As actual carbon calculation value for each shipment is used Calor do not provide one carbon value.

The carbon value range delivers a minimum 50% up to 90% emission savings against LPG.

Any saving comparison needs robust baseline information the starting point of our comparison is the fossil fuel carbon emission value.

Calor use different sources and baseline for our local markets, for the Republic of Ireland, SEAI, and for Northern Ireland, UK Government GHG conversion factors,

The below graph shows the carbon emission values in 2021 associated with the Republic of Ireland.

Minimum 50% Carbon Emissions

In addition to our own ISCC paperwork and records on BioLPG supporting the minimum 50%* savings claim in the above graph. This is in accordance with the latest European Union Renewable Energy Directive which requires a minimum 50% reduction for Biofuels compared the fossil fuel comparators.


Up to 90% Carbon Emissions,

In addition to our own ISCC paperwork and records there are industry reports on BioLPG supporting the up to 90% savings claim. This includes, Atlantic Consulting (2018) BioLPG: A survey of markets, feedstocks, process technologies, projects and environmental impacts. Commissioned by Liquid Gas Europe/WLPGA. This report stated BioLPG will deliver up to 90% carbon emissions.
