Personally...I think a very important environmental issue surrounding motorsport and the motor industry as a whole is tyre recycling. There is a growing problem of used tyre waste building up throughout the globe. It's very rare that you go to many of the worlds rivers now, without seeing an old car tyre somewhere in the water or on the riverbank...
I would be interested to know what the tyre companies are doing to develop new tyre compounds/technology that would reduce the amount of fossil fuel used to destroy old tyres which in itself, would help a significant and growing problem in the world with regards to waste rubber tyres. So in relation to MotoGP and other disciplines of motorsport, in addition to technologies focused on emissions, what else is being done to deal with the 'byproduct' for racing... for example....Where do all the MotoGP and F1 tyres go once they are used???
Where is the FIA's statement with regards to what they insist teams and tyre manufacturers do, in terms of safe environmental disposal of used race tyres?? (It may well be somewhere, I just have not been able to find it?)
Unfortunately, some loud and obnoxious environmentalists have long targeted motorsport and motorsport fans as spawn of the devil, when in reality I think the industry of motorsport is doing more than it's fair share right now, significantly more so than some of the greater polluters of this planet. But there is obviously always room for improvement and I think tyres are the next major area where the automotive industry needs to find a suitable solution to create biodegradeable tyres.
I dont know what happens to the resulting waste but Bridgestone chip all their present F1 tyres once they have been used (if they just drilled them they would still be able to be reversed engineered).
There are plenty of uses for used tyres but in the scheme of things the 20-30K of tyres used in F1 each year are just a small drop in the ocean compared to the 30M thrown away in the UK alone each year, and lets not even start on the US which scrap over 300M a year. Worldwide over 1B new tyres are made each year so its safe to assume almost the same number are scrapped.
There are many uses for old tyres and many businesses do make a good profit from the recycling of used tyres, however we will never be able to recycle 1B tyres a year.
Unfortunately to be more environmentally responsible with tyres it requires businesses to make less tyres so tyres that must last longer.
Companies like Dunlop and others have before developed tyres with greatly extended lifespans (up to 5 times the effective mileage of traditional tyres) but withdrew them from the market place because they reduced their profits.
So the companies will not do it on their own.
As for sport we have seen just this year how fans moan about the fact softer compounds could almost last a whole race so it looks like sport will not change either (can you imagine what the fans would say here if one set of tyres had to last a full weekend).
Either way it looks like the only way the growth of the tyre mountains can be reduced is to either have government legislation requiring minimum lifespans on tyres or as you touched upon biodegradable tyres, but would the public accept having to buy new tyres every year or so (even if the car had just been sat on their driveway or in the garage) irrespective of the wear or mileage done, or would the companies bring in the lobbyists to ensure no government addresses this problem (and protects their profits)?
I have to disagree with your last paragraph as clearly motorsport is not doing all it can or even its fair share. Do a simple search on what other industries are spending and doing each year to see what people who really want to change things are doing, then you will see what real actions are and then compare it to the fact that F1 and MotoGP cannot even be bothered to ensure the season is designed to reduce as much as possible the distance everyone travels (something that clearly would help and also would make not one iota of difference to the sporting spectacle), to see the truth.
F1 makes a lot of noise but has infact done very little so far to reduce its environmental impact and everything it has done so far was driven by the major motor manufacturers.
