Net zero: Drop-in decarbonisation solutions for wind manufacturing
Carbon fibre is critical to the wind energy sector - enabling stronger, longer, lighter blades. But it also comes with a high carbon footprint.
In fact, just 12% of blade mass can account for nearly 50% of its lifetime emissions.
This report explores how the industry can start reducing that footprint now, using drop-in solutions that align with current production methods - without waiting for new plant builds or deep infrastructure shifts.
It’s designed for materials producers, blade OEMs, sustainability leads, and others looking to make smart early moves towards net zero.
What this report offers
The paper sets out a clear picture of which early-stage interventions offer the greatest impact with the least disruption. These are solutions that carbon fibre producers and supply chains can implement with current infrastructure - enabling rapid progress while bigger, longer-term shifts continue to develop.
It builds on full lifecycle analysis and process modelling from the SusWIND programme and serves as a companion to the second paper in this series, Practical Pathways to Net Zero.
Key insights at a glance
- Bio-based feedstocks offer immediate gains: Switching to acrylonitrile derived from renewable sources (Bio-ACN) can cut carbon fibre footprint by up to 9 kg CO2e per kg of product - one of the most effective near-term levers.
- Electricity source matters as much as the process: Where oxidation and carbonisation are already electrified, switching to net zero electricity can nearly halve carbon impact. Securing REGO-backed power accelerates this.
- Thermal energy is the next frontier: BioMethane can serve as a short-term substitute for gas (2025–2040), before moving to e-Methane once grid electricity is further decarbonised.
- Not all green fuels perform equally: Blending hydrogen into natural gas has minimal effect in lifecycle terms. Meanwhile, pure hydrogen heating introduces complexity and uncertainty - best treated as a future option rather than a current fix.
- Location and grid mix shape what’s possible: Siting new capacity in areas with greener electricity - or investing in on-site renewables - can significantly improve outcomes and reduce reliance on future fuel rollouts.
A roadmap that fits the real world
The report offers a UK-based timeline for action, grounded in current market readiness:
- Now: Switch to Bio-ACN feedstocks
- 2030: Transition to BioMethane for thermal needs
- 2040: Adopt e-Methane where thermal energy is still required
- Ongoing: Secure net zero electricity, and invest in local generation where possible
This roadmap aligns emissions reduction with market and technology maturity - reducing both risk and delay.
Why it matters for wind energy
Decarbonising carbon fibre has the potential to cut wind blade emissions by over 50%. While other lifecycle stages offer smaller gains, materials and manufacturing account for the bulk of embedded emissions - and decisions made at this stage are locked in for decades.
Who should read this

To support these kinds of developments, NCC and CPI are working together to strengthen innovation capabilities that are essential to the UK's supply and manufacture of advanced materials. Specifically, the focus is to develop sovereign capability for the production of novel carbon fibre formulations and processing techniques, which will, ultimately, support tangible advances in performance, cost and sustainability.
