It may cost a lot of green, but Macs and Apple are particularly green. Apple has many protocols anand material regulations they use in their products. That's one of the reasons they cost so much, is the good materials they source.
I will agree with the labor problem, but they have good materials. See the model you might want, they have PDFs discussing the carbon footprint. This is the report for the model I own.
Also they offer recycling programs in most countries. Regardless of the brand, they will recycle your old computer. And if you recycle your Mac while it has value, they give you store credit- a nice perk. Some apple stores do it, or it's free online.
