For many years it has only been scientists, environmental charities and eco warriors who have been concerned about the greenhouse effect and for the majority of us we did not think that us or our grandchildren would be troubled by the results of us polluting the earth.
But things have now changed and most world leader's have put the environmental problem at the top of their agendas and this has moved the subject very much into main stream public debate. There have been green taxes implemented as well as getting people to buy unleaded petrol instead of the leaded version. As we are now seeing we are all being affected by the damage done to our environment and so we now need to do something about it before it is too late.
However the air freight industry is being challenged to become more green and there are a number of International Air Freight Companies who have introduced what is known as "offset policies".
So what this means is that every time some cargo is flown around the world the International Air Freight Company in question is investing a certain amount of money into environmental projects as well.
But there are some critics of these companies who say that this is simply not good enough and that they should in fact be trying to reduce the carbon emissions that their aircraft produce rather than just doing something good for the environment in order to balance the books.
Reports are showing that carbon emissions were expected to reach 25 billion tons in 2006 and of this amount between 4-7% would be caused by air travel which includes air freight in this figure.
An agreement signed by many European countries known as the Kyoto Protocol Agreement are committed to reducing the carbon emissions for signatory countries and it aims to do this by setting limits for 2008-2012.
Unfortunately the USA declined not to sign the agreement.
But there is hope that this agreement along with the offset policies being adopted by a lot of the international air freight company's will produce the changes that this planet so desperately needs.
