Prysmian unveils carbon-negative cable
New cable absorbs more CO₂ than it emits, marking a major step forward in low-carbon grid infrastructure.

Italy: Prysmian has introduced what it describes as the world’s first cable with a negative carbon footprint, representing a major step in reducing emissions across power grid infrastructure.
The assessment follows a cradle-to-gate approach, meaning that throughout sourcing and manufacturing, the cable removes more carbon emissions than it produces. This delivers a measurable positive impact on the climate.
The innovation is based on two key developments. First, advanced engineering has enabled an optimised cable design that maintains full electrical and mechanical performance. Second, the use of next-generation materials – including bio-polymers, recycled, and low-carbon components – significantly reduces emissions, ultimately achieving a negative carbon balance.
The new cable can be integrated into existing grid systems, making it suitable for immediate adoption without major design changes. Prysmian plans to begin industrialising the technology across its global manufacturing network, with initial deployment in its Power Grid business scheduled for the second half of 2026. The solution is currently patent pending.
According to company representatives, the innovation reflects a strong focus on research, material development, and circular design. The cable can achieve a negative carbon balance of up to one tonne of CO₂ absorbed per kilometre.
