There will probably be attempts at watering down the proposal or leave loopholes for greenwashing. But the simple fact that these things get discussed and that major companies move to the right direction is a form of progress in itself.
This web page that says Apple is environmentally friendly weighs more than 20 MB.
edit: I just read it, there isn't anything about screen, battery and chipset / CPU production and material sourcing. In short, the big part of what is an actual issue with computer hardware and the environment.
Look, I'm not going to convince you at this point. You are also absolutely not going to convince me that this page should be trusted.
Let me just suggest you that if you are going to take marketing material at face value, be my guest, but I suspect you are in for some fun rides.
And good luck convincing people with (arguments coming from) marketing material too. I suspect this won't work with many people seeking more robust stuff.
See my other comment on actual elements that show that Apple is not that geared toward being environmentally friendly. These elements need to be addressed before I start changing my mind on this.
They could continue by not making you want to buy shiny new devices each year, growing crazy hype for their annual event, and instead they could base their communication on the idea that you should avoid buying unnecessary stuff, and keep your hardware as long as possible.
Then, they could let us install third party OSes on perfectly good hardware they decided to stop supporting. Or at least let us install an up to date (third party) browser on this hardware. Yes, the iPad 2 is stuck in 2015 for instance. I'd very much like to be able to install some lightweight linux distro on the one I got which was left unused in a drawer so it can be useful again and do something else than displaying PDFs.
Then, they could stop gluing all the things together and not force you to change the whole motherboard if one key from their fragile keyboard died, and make their hardware at least somewhat repairable. They could stop handing you out a new device when something minor broke on yours.
So far from environmentally-friendly. It's like they haven't even begun trying, actually. It's almost as if it were against their bottom line. They wish it weren't like this not too hard. It's not like they are lacking the money, they are the richest company in the world.

for example, right now a given company has no idea how much carbon their electricity/building/deliveries/whatever cost, so they'd have to figure that out themselves... but if everyone knew that from the ground up, that'd be a lot easier for any other company to produce.
there could also be network effects if those reports had to be public, because common vendors' data could be re-used. e.g. UPS knows that their carbon costs for delivering packages are X KG of carbon per KgKm of package-travel, or something, so then everyone can use that factor in their own maths.
It'd be incredible effort still, but I see the value. So much "climate damage" now is just classed as economic externalities simply because we don't have a good way to quantify it reliably. Requiring companies to know and disclose that would go a long way to addressing that, and enabling strategic policy response.
The part that they didn't put in the letter:
Now they want to make a law to sell that methodology and model. iFootprint will presumably be announced at the wwdc just before the law takes effect.
