Just over half of businesses consider themselves well informed on sustainability, down from 71% last year.
On a more positive note, the figures from Dublin Chamber's latest sustainability survey shows that staff engagement with sustainability is on the rise.
Last year, 12% of respondents said that "staff are not enthusiastic about sustainability", only 8% chose that answer this year.
"It is positive to see that staff engagement in sustainability is on the rise, it counters the idea that lack of expertise equates to apathy - and highlights the importance of training programmes - such as Dublin Chamber's Sustainability Academy- in turning interest into knowledge," said Mary Rose Burke, CEO of Dublin Chamber.
When it comes to what businesses associate most with "sustainability", organisations primarily identify sustainability with improvements in waste, energy efficiency, and in reducing their carbon footprint.
Nearly half of those surveyed reported that recent trends in energy costs, exacerbated by war in Ukraine, have prompted a change in their company's energy usage, whilst 33% stated that it was too early to say.
Yet just 55% of organisations prioritise energy suppliers who produce energy from sustainable sources.
