Examples of innovations that are installed in specific sites of our industry. Let's have first look on our production volumes. If you figure out, you can make them back already to the year 1988. If you see the year 2009, you see you have also been hit by the crisis, and at the moment we are trying to do our best to recover the levels we had before the crisis.
On average, we produce around 4.5 million tons of cement. The number I would like to come back later on and if you could produce a little bit more three million tons of green car. Let's also look at the few areas, we use for the green product. Lets have a special look on alternative fuels and here we can see a vast increase of use of alternative fuels.
We see many colors here indicated by different fractions of alternative fuels. On the bottom you can see the use of end of live tires which already started and in the early 80's.Waste oil has come back a little but it has been replaced as solvents and you see this big yellow part here which which makes clear that almost half of the whole energy we use for clinker production comes of plastic waste.
There are many colors here. There is one thing we cannot find here, it's pet coke because in Austria, pet coke is not considered as an alternative fuel. It is considered as a conventional fuel so still without pet coke we have a very high share of alternative substitution rates here of 75%. The use of pet coke has come down already to less than 7% and the use of lignite and black coal is less than 15% now in our industry.
Some of the factors you see here come together with some organic parts which are going to help us for the initial trading scheme in terms of neutral emissions, and we'll come back to that a little bit later on. Now I just want to compare this very high number of 75% with some indicators from other countries, and those you know, are already familiar with the cement sustainability initiative, and they're getting the numbers right.
Data base is, here you can see the substitution rate in other countries. It starts with about 1% in China goes up to 12, 15% in Canada and United States and then on the far right you see most European countries which comes in hand with better developed regulation in terms of waste treatment. Austria has indeed a very good high share of 72% in the year 2013 which is four times as much as the global average, at the moment of 15% and still almost twice as much as the European average of 38% in the European Union.
Having a look at the CO2 initial factors of these fuels, we see a bandwidth here on the upper bandwidth, we see probably the most convenient fuel in the cement industry worldwide which is black coal, and here to show you the development of our entire fuel mix, which we're able to pin down the initial to 68 kg CO2 per gigajoule. So, we are already way below the average use of black coal.
If you have a special look on alternative fuels, and the biorgnic fractions to see we already hit a level of natural gas which is considered the most friendly for self use in terms of climate protection. Here we can see the development of the clinker in our cement. We already have the level below 80% in the year 1997. 2014 was really the second year where we were able to bring down the clinker content in our cements to less than 70% and also here I would like to compare this to some prognosis to international energy agency did back then in the year 2009, but it prognosis that the average clinker content in the year 2030 will be around 73% world wide and if you still consider the second number which is still 35 years away in the year 2050, you can see already today we lie lower than that prognosis with 71% for the year 2050.
