CityFibre has hailed full-fibre broadband as a much greener alternative to copper-based systems.
According to a study commissioned by the provider, copper is "significantly more carbon-intensive" than fibre at all stages of its lifecycle, from extraction and manufacture to operation and maintenance.
By contrast, the report by Carbon Smart argued that full-fibre networks are much more energy-efficient, as they require no power to street cabinets and their services are more reliable.
Furthermore, it suggested that since legacy copper-based infrastructure is becoming increasingly unable to cope with people's data requirements, relying on it heavily is delaying the growth of greener technological developments, such as tele-healthcare and homeworking.
Greg Mesch, Founder and Chief Executive of CityFibre, has welcomed the report's conclusions, saying there is "no doubt" that full-fibre is the only digital infrastructure capable of underpinning a "green revolution".
"Ensuring a greener future for us all, requires transformational change to the way we live and work," he commented.
"Technology is central to this change, with exciting and effective solutions being pioneered across the world as we speak."
Ben Murray, Managing Director at Carbon Smart, added that the UK needs to "rapidly transition" from old technologies and working practices to more sustainable alternatives.
He insisted that full-fibre infrastructure has a "critical role" to play, as the technology offers clear environmental, social, economic and technological benefits. "Without it, our ability to build a sustainable future is in doubt," Mr Murray stated.
CityFibre recently announced a long-term strategic partnership with Vodafone that will lead to up to five million premises having access to ultrafast broadband by 2025.
The first phase will see fibre-to-the-premises technology - which is currently only available to around three per cent of UK premises - being deployed to one million homes and businesses over three years.
Vodafone and CityFibre will then have the option of extending the commercial terms of their agreement to reach a further four million premises by 2025.
