Achieving near-zero emissions by 2050 is a formidable challenge for the UK, demanding transformative changes in energy, technology, and economic strategies. Current policies fall significantly short of the target, leaving critical questions about the costs, feasibility, and societal impacts of decarbonisation unanswered.
This report by Dr Simon H. Roberts and Dr Colin J. Axon from Brunel University delves into the practicalities of reducing greenhouse gas emissions using real-world data and modelling to assess the path forward.
Key findings:
-
Existing UK policies will only reduce emissions by 57% by 2050, far from the near-zero target.
-
A balanced approach prioritising practical technological advances is essential to avoid unsustainable reliance on expensive and untested solutions.
-
Near-zero emissions are feasible through increased use of hydrogen, electrification, and technologies like ammonia and synthetic fuels for transport and industry.
-
Achieving near-zero emissions could require investment equalling 3% of GDP annually, impacting sectors like construction and manufacturing.
-
Data-driven modelling highlights the importance of offshore wind, hydrogen production, and floating technologies, alongside reduced dependency on imported fuels.
