Transforming HVAC for a
sustainable future The conclusion of COP28 in December 2023 marked a pivotal moment in the global effort to combat climate change
mong the many commitments made, the Global Cooling Pledge emerged as a beacon of hope for a sustainable future. The pledge, taken by 63 countries, outlines a commitment to tackle cooling-related emissions, particularly in the HVAC industry. The issue will not disappear, as climate change is increasing our global temperatures and instances of extreme heat, more than one billion people are now at high risk of suffering serious consequences as a result of extreme heat alongside a lack of effective cooling. However, the more we try to keep cool, the more we continue to heat the planet, with conventional cooling systems such as air conditioning costing us seven per cent in greenhouse gas emissions.
A The Pledge
The Global Cooling Pledge formed one of nine non-negotiated declarations that were announced at COP28. Its aims include an international ambition and cooperation to reduce cooling related emissions by 68 per cent by 2050, to increase the access to sustainable cooling by 2030 and to increase the global average efficiency of new air conditioners by 50 per cent. In support of the pledge, the United Nation’s Cool Coalition created a report, Keeping it Chill: How to Meet Cooling Demands while Cutting

Emissions, with its key takeaways helping form the pledge. The report found if the world was to continue on the same trajectory with the same policies, our global electricity consumption would be required to double.
Meeting the new standards will be a major challenge but it is achievable. To meet them, it is vital to adopt new innovative technologies, and look towards a scaled-up adoption of smart technologies that can help monitor and reduce our cooling related energy consumption.
Redefining HVAC for a
Sustainable Future Sontay, a market leader in providing sensing and peripheral devices for a range of building controls
including HVAC, recognises the importance of enhancing the energy efficiency of our HVAC systems and creating smarter buildings. Sontay’s wide range of innovative, smart products not only enhance safety and improves health and well-being of occupants, but also offers energy saving measures that can help in the fight to reduce cooling related emissions.
Smart networkable controllers and temperature sensors can monitor the temperature of an internal or external space, and automatically adjust cooling or heating outputs based on variable temperature or occupancy levels. Other products such as the Capillary Frost Thermostat provide a switch output based on the average temperature detected along a capillary sensor. It can be commonly used to prevent the icing up of filters, fans and coils, further contributing to an increase in energy efficiency and therefore a decrease in cooling emissions.
The Global Cooling Pledge marks an important moment in the worldwide fight against climate change, and Sontay is proud to play a part in this transformative initiative. By prioritising innovation, sustainability and efficiency, Sontay is spearheading changes in the HVAC industry and developing intelligent buildings that address today’s demands, while protecting the planet for future generations.
