New research has revealed “widespread confusion” among UK businesses when it comes to what constitutes sustainable alternatives to conventional fuels.

According to a fresh study by Certas Energy, while there is an appetite to consider switching from conventional fuels across multiple industries – with 69 per cent of UK construction, transport and public sector representatives likely to source alternative fuels in the next 12 months – there is a clear lack of awareness over which energy options are sustainable.

Indeed, a fifth of respondents were unable to identify the most sustainable fuel type.

Despite the impending introduction of clean air regulations across the country, Certas said its research also suggests the majority of businesses have yet to find a fuel type that confidently addresses the required criteria for a viable alternative energy solution. Over 60 per cent of businesses remain reliant on diesel engines, and only two per cent currently use alternative fuels.

“The results of the research are certainly eye-opening – there is a clear demand for alternatives to standard diesel, yet also confusion around which way to turn for a solution,” said Brian Worrall, director of corporate affairs at Certas Energy.

“In reality, there is no ‘silver bullet’ solution to overcome all air quality issues, but rather a mix of different technologies and options that can take us on the journey from today, towards the ultimate end-goal of zero emissions in the future,” he concluded.
