Ozone - a bigger problem than first thought?

What is ozone?

Ozone is created in the upper and lower atmospheres by oxygen molecules and UV radiation interacting, and chemical reactions between pollutants like vehicle exhaust fumes and other emissions, respectively. The ozone layer is vital as it filters dangerous ultraviolet radiation from reaching the Earth’s surface. Ozone is recognised as a hazardous pollutant.

What’s the current problem?

Ozone may be weakening one of the Earth’s most important cooling mechanisms, making it a more significant greenhouse gas than previously thought, research has found. A new study from Reading University has revealed that changes to ozone levels were responsible for almost a third of the warming seen in ocean waters bordering Antarctica in the second half of the 20th century. This affects its role as one of the main regions for soaking up excess heat as the planet warms.

What this means for your business?

Whilst going “green” is not at the top of many agendas, there are some simple things that can be done by all businesses to reduce the negative effects of ozone, but which will also have a positive business impact and may reduce overheads.

Is there a legal obligation?

It is not just for ethical reasons that you should reduce air pollution. There is legislation that’s applicable for monitoring and reducing polluting emissions to air such as the Clean Air Act 1993 . Use our register of environmental legislation - air pollution to help decide if you are doing enough to control your emissions and reduce the likelihood of receiving a hefty fine from the Environment Agency (see The next step ).

Tip. Use air-friendly products to reduce pollution. Select water-based solvents and paints or those with low volatile organic compound content. Brush paint instead of spraying. Make sure that lids are securely fixed when not in use.

Tip. Use A++ rated equipment if possible. Both refrigerators and air conditioning units release harmful chemicals and greenhouse gases that damage the atmosphere. The original culprits are not in use any more but their replacement hydrofluorocarbons are still 1,000 to 9,000 times more potent than CO₂ in terms of climate impact. A++ equipment will also be cheaper to run as it will use less power, thereby reducing your energy consumption and lowering ongoing bills.

Tip. If you use the following equipment, you’re responsible for getting it checked for F gas leaks; refrigeration, air-conditioning equipment, heat pumps, fire protection equipment, refrigeration units, trucks and trailers. Responsibility for stopping leaks of F gas from equipment is shared between the users and the technicians who install, maintain or dispose of it.

Tip. Have an emergency plan in place, such as immediate shutdown, in case you have leaking plant, as this will reduce environmental impact and could reduce repair or replacement costs.
