Worse than aluminum or steel? Both require mining and refining, with massive amounts of energy to process.
The recycle issue is of little concern since we aren't at risk of running out of carbon.

It's a bit difficult to know for sure but I've read report that say it requires 14 times more energy to produce than steel. There is also a lot of wastage in the layup process, I've read around 1/3 of the material is wastage and most ends up in land fill.
Recycling is the issue as it is the getting the raw materials that takes the most energy.
