Understanding the environmental impacts of fiber and copper communications networks

In today’s world, staying connected is essential. High-speed internet and reliable communication channels are vital for enabling businesses to operate efficiently, fostering innovation and growth, promoting inclusion, increasing education, and much more. As communications companies transition to fiber optic systems, they also face the challenge of maintaining existing copper networks. Both the maintenance of existing copper networks and the upgrade to fiber optic networks have environmental consequences, which are explored in detail in this white paper.

In a study commissioned by USTelecom – The Broadband Association, Ramboll investigated environmental impacts of maintaining copper-based infrastructure versus installing new fiber optic infrastructure. The analysis included carbon emissions, effects on biodiversity, and other environmental considerations. The paper examines the key areas of impact for each option, drawing on relevant studies to provide a comprehensive understanding of how these technologies affect the environment. Specifically, the paper analyzes impacts across each phase of the life cycle - manufacturing and installation; operations; and end of life – and details the potential environmental impacts that should be considered.

The findings reveal that while fiber optic networks deliver substantial long-term environmental benefits once operational, their initial stages – manufacturing and installation – tend to have higher environmental impacts compared to maintaining existing copper networks.
