Climate Change is recognised as one of the greatest environmental threats facing the World today and it has long been appreciated that we all have our part to play in reducing the impact of the motor vehicle.

CO₂ is the most important of the greenhouse gases which are contributing to Climate Change. Unless action is taken to reduce greenhouse gas emissions, such as CO₂, the whole pattern of the World's weather could change, increasing the frequency and intensity of heat waves, floods, droughts and storms.

Compared to improvements in the emissions of toxic pollutants, there has been less progress on reducing CO₂ from cars. For a given type of fuel the CO₂ emissions of a car are directly proportional to the quantity of fuel consumed. Until recently the average fuel consumption of new cars was unchanged relative to that in the mid 1980’s. This was because, while engines had become more efficient over this period, average vehicle mass had increased due to additional features to meet crash safety requirements and the widespread addition of features such as power assisted steering and air conditioning.

The other pollutants from petrol, diesel and alternative fuel engines are mainly Carbon Monoxide, Oxides of Nitrogen, un-burnt Hydrocarbons and fine particles. The first three are gases and are invisible. Fine particles are usually invisible although in certain operating conditions diesels will produce visible particles, appearing as smoke. Petrol engines will also produce visible particles if they are burning engine oil or running rich, for example, following a cold start. Unlike CO₂, emissions of these pollutants are not directly linked to fuel consumption.

The fitting of Magno-Flo™ has been proven to reduce emissions from vehicle exhausts and can be measured both scientifically and visually by seeing a reduction in smoke emissions.
