Global warming...

No matter what your personal beliefs about mankind’s part in Global Warming and climate change, our Government and those of many other nations have decided to unify their efforts in an attempt to reduce the impact by placing quotas on the amount of certain so called "Greenhouse Gases" which can be released into the environment.

In this section of the website, MAC Ltd would like to provide some information about the part that air conditioning and related technology have played in the past in contributing to global warming, and the remedies in place to ensure that modern air conditioning systems, when correctly installed, maintained and at the end of the useful life, disposed of, should have negligible impact in the future.

Climate change...

Climate change is the greatest environmental challenge facing the world today. Rising global temperatures will bring changes in weather patterns, rising sea levels and increased frequency and intensity of extreme weather. The effects will be felt in the UK.



F-Gases (Fluorinated greenhouse gases) are manmade gases that are used in a number of different sectors. The most commonly used F-gases belong to a class of chemicals known as hydrofluorocarbons (HFCs).

These HFCs were virtually unused before 1990 but since then have been used in, for example, refrigeration and air conditioning, to replace ozone-depleting substances such as:

◦ Chlorofluorocarbons (CFCs)

◦ Hydrochlorofluorocarbons (HCFCs)


The Kyoto Protocol...

The Kyoto Protocol forms part of the international community’s responses to climate change by, in part, identifying a basket of gases which have a global warming potential.

As part of the European Union’s obligations under the Kyoto Protocol, the Community has taken action to regulate fluorinated greenhouse gases through EC Regulation No 842/2006 on certain fluorinated greenhouse gases. The principal objective is to contain, prevent and thereby reduce emissions of fluorinated gases.


How does it affect you?

The Fluorinated Greenhouse Gases Regulations 2008 (FGG Regulations 2008) entered into force on 15 February 2008 and put in place offences and penalties applicable in Great Britain. Whatever your current level of awareness of the new EC Regulation on F Gases may be, the fact is that it applies to almost any building with an air conditioning system that utilises refrigerant and coolants to reduce the interior temperature.

The main sectors affected where F gases are used are:

◦ Stationary refrigeration, air-conditioning and heat pumps
◦ Stationary fire protection
◦ High voltage switchgear (electrical transmission networks)
◦ Air-conditioners in cars and light vans

If you or your company/organisation own, use, work on, contract out work or provide services for work on equipment in use in the sectors above, you will need to make sure you are complying with the relevant provisions in the EC F Gas Regulation and the FGG Regulations 2008.


The industry responds

The entire air conditioning sector is responding positively to help put a halt to climate change.

The increased energy efficiency of modern air conditioning systems, coupled with a complete stop in the use of greenhouse gases in the production and use of the systems is a positive step in the forward direction.

Indeed, it is becoming increasingly apparent the positive affects that air conditioning and related technologies can have on health, comfort and general well-being. Should the increase in temperature from climate change become a reality, air conditioning may be the only resource to rely on to create a locally controlled climate for your home or business.
