Changing legislation for decarbonisation


Steve Molloy


Decarbonising the built environment is essential if the UK is to achieve net zero, and addressing pressing environmental challenges posed by emissions is a crucial concern for the HVAC sector. Buildings and construction are responsible for nearly 40% of global greenhouse gas emissions, primarily due to the energy consumed for heating, cooling, lighting, and daily operations. To combat this, various standards and certifi cations have emerged, encouraging sustainable and low-carbon practices and setting benchmarks that guide the design, construction, and operation of buildings toward a greener future. Steve Molloy, sustainability and commercial solutions manager at Daikin, explains more.

n the UK, the ambition to reach net zero by 2050 has led to signifi cant regulatory developments across all industries, with the HVAC sector facing a critical challenge - the


reduction of hydrofl uorocarbons (HFCs). Some of these gases possess a high Global Warming Potential (GWP), which can potentially trap considerably more heat in the atmosphere than carbon dioxide over a specifi c period. Addressing the use of HFCs is vital in reducing the

environmental impact of HVAC systems and meeting the UK’s climate goals. The European Commission’s F-gas Regulation is pivotal in


this eff ort, introducing stringent measures designed to phase down HFC usage. This regulation limits the quantity of HFCs on the market, enforces tighter emission controls, enhances monitoring and enforcement, and caps EU production while allocating quotas to manufacturers.
