The need for cleaner and more sustainable energy sources has never been more pressing. We believe the best solution for a cleaner future is to have a range of different sources powering our transport network. That’s where sustainable fuels come in. Sustainable liquid fuels could begin making a difference almost immediately, reducing greenhouse gas by up to 80% if fully replacing their fossil-based equivalent. In response, we have developed a dedicated range of sustainable fuels perfect for classic vehicles. But what exactly are sustainable fuels? How do they differ from traditional fossil fuels, and what promise do they hold for the future of energy?


What are sustainable fuels?

Sustainable fuels is the collective term for all types of sustainable fuel. Also known as renewable fuels or green fuels, sustainable fuels are energy sources derived from renewable resources that have a lower environmental impact than conventional fuels.

There are three main categories: Biofuels which are the type of we we use to create our SUSTAIN Classic range. Synthetics fuels and recycled carbon fuels.

What makes a fuel ‘sustainable’?

A fuel is considered “sustainable” if it effectively recycles the carbon while meeting certain criteria that collectively ensure it has a minimal or positive impact on the environment, society, and economy over its entire lifecycle. 

You can see the full process involved in creating the SUSTAIN Fuels range here.

How do sustainable fuels differ from fossil fuels?

Fossil fuels are derived from organic matter formed over millions of years which are extracted and causes new CO2 to be released and introduced into the atmosphere when burned. Whereas for sustainable fuels they are derived from renewable sources like plants, animal waste, or water.

Sustainable fuels are replenishable over a short period, whereas fossil fuels are non-renewable and deplete over time. Meaning the production and use of sustainable fuels are usually less harmful to the environment compared to extracting and burning fossil fuels and not introducing any extra carbon into the atmosphere.

What is the difference in sustainable fuels?

There are three different types of sustainable fuels. Biofuels, Synthetic Fuels and Recycled Carbon Fuels.

For a further breakdown please see the following glossary and guide with a more in-depth explanation of the different sustainable fuels and related technical terms.

How can sustainable fuels contribute to energy security?

By reducing our dependence on imported fossil fuels, sustainable fuel options can help ensure a more stable and predictable energy supply with the greater diversity of options. This presents numerous opportunities for economic growth, technological innovation, and environmental sustainability.

It makes sense that we employ a suite of effective solutions, to tackle these issues as quickly as possible. Imposing a single solution policy suppresses innovation that might find better or complementary ones.

Can waste products be converted into sustainable fuel?

Absolutely. Waste products like used vegetable oil, municipal waste, agricultural residue, and even plastics can be converted into biofuels or other forms of sustainable energy.

What distinguishes ‘sustainable’ fuels from ‘renewable’ fuels?

While both terms emphasise environmental responsibility, ‘renewable’ specifically refers to fuels sourced from resources that can be naturally replenished, whereas “sustainable” encompasses broader considerations, taking into account the entire lifecycle of the fuel, as well as economic and social factors.

A renewable fuel might not be sustainable if its production or use causes significant environmental damage or social issues.

What are the advantages of sustainable fuels?

Reduced greenhouse gas emissions, less reliance on non-renewable resources, potential for local economic development, and decreased pollution are some benefits of sustainable fuels.

Are there any economic benefits to using sustainable fuels?

Sustainable fuels can offer savings over time due to potential tax incentives, lower maintenance costs, and reduced fuel expenses, especially as fossil fuel prices fluctuate.

How can sustainable fuels impact the economy?

It can present new opportunities by creating jobs in research, production, and distribution, reducing dependency on foreign oil, and potentially stabilising energy prices.

How do sustainable fuels reduce environmental impact compared to regular petrol or diesel?

Sustainable fuels, when derived from renewable sources, emit fewer greenhouse gases and pollutants, thus reducing carbon footprints and improving air quality.

What qualifies as a sustainable fuel for cars?

A sustainable fuel is derived from renewable resources, reduces greenhouse gas emissions, minimises environmental harm, and is economically viable over the long term.

What are the common types of sustainable fuels used in cars?

Common sustainable fuels include biodiesel, ethanol, hydrogen fuel cells, and electricity from renewable sources for electric vehicles.
