Decarbonising heating and cooling integral to reaching net zero
As Glasgow prepares to host COP26, Dave Pearson of Star Refrigeration is determined to show world leaders how carbon neutral heating and cooling technology can be successful.
A
ll eyes are on Scotland next week as Glasgow hosts arguably the most important climate change summit to date – the 26th UN Climate Change Conference of the Parties. Running from 31 October to 12 November 2021, the event is part of the urgent action required to keep the planet’s average global temperature from rising by over 1.5° and prevent disastrous irreversible damage. Whilst transport and diet will undoubtedly
dominate the headlines and priority themes for COP26, in reality the more ubiquitous cooling and heating are the single largest human activities affecting climate. Essential to our everyday life, the cold chain (food production and storage), pharmaceuticals, data centres, comfort cooling and heating are both omnipresent and destructive. Our reliance
on cooling was recently highlighted with the transportation of the Covid vaccine. These sectors are also responsible for
the increase in greenhouse gases in the atmosphere over the last decades. In fact cooling and heating are estimated to account for around half of the end-use energy worldwide and 40% of its energy-related global carbon dioxide (CO2
) emission. Add in
the use in many systems of synthetic working fluids (cousins of mainly banned CFCs and HFCs), and the climate impact is potentially devastating.
More measures to avoid locking-in higher emissions are required in this area to help countries move towards carbon neutral heating and cooling. Dave Pearson, Group Sustainable Director at Star Refrigeration said: “Star have always
been at the forefront of green/sustainable engineering with our innovative climate- friendly equipment, durable system designs, energy optimised control software and aftercare to maximise energy efficiency. However, more must be done to decarbonise heat and cooling, there is no time left for gradual shifts. Governments must act decisively to prioritise actions that improve the uptake of low carbon technology and practices.”
Mr Pearson thinks the adoption of natural refrigeration technology as well as large scale heat pumps which can provide combined cooling and heating is the only way to ensure the Paris Agreement’s net zero targets are achieved. “Refrigeration systems which use zero carbon refrigerants and energy efficient designs minimise energy consumption and
