Sportscar Racing and Global Warming

[old man]

As we appear to have yet another new scientific report coming out today (February 3rd 2007) saying that we, as humans, are major contributors to global warming should the racing sportscar world be taking action, perhaps drastic action to show that we care about it and are trying to do something positive?

Things that occur to me start with some actions already on going like alternative fuels to standard petrol or gas, is what is happening enough or should these receive more of a regulatory push?

Should we look to reducing engine sizes in LMP and GT classes setting say a 2 litre limit for LMP1 and 1 litre for LM2, similar sizes for GT classes?

Should we have more regional championships to cut down travel with just a few very top meetings like Le Mans or Sebring/Daytona that would be "finals" for which regional championships qualify?

Should we find some way of limiting the carbon footprint, spectators attending meetings have an impact?

All sports make an impact because of the latter but Motor Racing by it's nature could attract the attention of the legislators and perhaps we should beet them to the draw

In the 50's and 60's GP cars were down to 1.5.litres, F3 1.0litre and lots of 1100cc and 2000cc cars raced in the sports categories. Since those days engines have got bigger and yes, more efficient but could we do more and still have exciting racing?
