As customers and stakeholders scrutinise companies’ sustainability claims more closely, it is becoming more important than ever for businesses to prove that they are operating in an environmentally responsible way. Andy Kellett, National Account Manager FLTs at Calor, explains how those using renewable fuels such as bioLPG for their FLT fleet can demonstrate their CO2 savings in a robust and fully auditable manner.

In an era where supply chains and business processes are becoming more complex, being able to calculate carbon reductions made in a trustworthy way cannot be underestimated. Afterall, figures that have been accurately and consistently captured provide all stakeholders with the confidence that claims made about carbon savings are indeed true.

When reporting using the Greenhouse Gas Protocol for instance, you must use an instrument that meets the Protocol’s quality criteria, as evidence of any renewable energy consumption. What’s more, by using Renewable Gas Guarantees of Origin (RGGOs) issued by independent schemes, businesses that consume renewable fuels can be fully transparent about how their carbon savings are calculated.

For example, because we work with the Green Gas Certification Scheme (GGCS), companies who purchase Calor’s blend of bioLPG and conventional LPG to power their fork lift trucks (FLTs) can access certificates of their RGGOs. Because bioLPG is a renewable fuel made from a blend of waste, residues and sustainably sourced materials, a mix of 40% bioLPG and 60% conventional LPG can deliver carbon savings of up to 32%, compared to using conventional LPG alone.

To begin the process, companies that produce bioLPG provide an International Sustainability Carbon Certification (ISCC) Proof of Sustainability. This verifies the carbon savings and that the feedstock is from a sustainable source.

The quantity of bioLPG delivered into the country as part of that particular consignment is then logged by the GGCS, creating a bank of RGGOs available for companies, like Calor, to issue to its green customers on a bioLPG tariff. The system automatically calculates the amount of RGGOs for the customer depending on the volume of gas they receive. Recognised certificates detailing the carbon savings the customer has made can be downloaded from the GGCS website, which can be used for auditing purposes.

This system ensures certificates and carbon saving calculations are third-party qualified, fully auditable for customers and monitored by the GGCS. Moreover, it guarantees that the RGGOs given for the bioLPG that customers receive has not been double counted or double sold.

Opting for a supplier that offers an objective means of tracking transactions of green gas through the supply chain provides end users with a robust way of proving their carbon reductions. With the added ability to easily access this information, businesses can show their own clients, with confidence, that they are taking action on building a more sustainable future.
