Sustainable Industry

Competitive Business

A message from our CEO Jim Gannon

In an era of rapid change, sustainability is no longer an optional extra; it is a major strategic driver for businesses and a key component of competitiveness. A sustainable approach to energy, from the perspective of both efficiency and the use of renewables, often represents the lowest risk and most cost effective investment for companies seeking to increase their environmental performance. With shareholders demanding an optimum return on investment, it is also critically important that the full benefits of a sustainable approach to energy are recognised. In addition to the bottom line cost savings, rapid returns on investment, and quantifiable CSR contributions, strategic approaches to energy management can embed a culture of innovation and continuous improvement.

SEAI's Large Industry Energy Network (LIEN), a voluntary grouping of over 190 of Ireland's largest energy users, shares a common goal to improve energy performance and to apply energy efficiency best practices. It is interesting to see that, in contrast to the national increase in energy use, the energy consumption of the Network actually decreased by 2% in 2015. Members continue to improve their sustainability and become more competitive businesses as a result. We would also note that increasingly, across many organisations, a new goal of decarbonising energy supply is also growing in importance, and this is something we will give more focus to as demand increases for advice and support in this area.

All large businesses with an interest in pursuing a sustainable and strategic approach to energy should become members of LIEN. The benefits are simply too great to be ignored.
