Debug This Sentence

I have a sentence structure question. the fllowing sentence sort of makes sense, but I'm wondering if anyone can see any flaws and possibly optimise it, as it may be a little long winded? Here goes:

 "The fact that the UK plans to cut carbon emissions by 60% by 2050 and worldwide government nanotechnology investment is US$4 billion, to date, indicates a strong belief that nanotechnology is the key to addressing our environmental issues."

This place is fantastic, I wish I knew about it a long time ago!

Thank you guys! 

 Your version "The facts... indicates" sounds much better. I'll rework it and post it up for eval.

 You were also right about nanotech being "tiny" science. My whole report is on how renaissance of nanotechnology will stem from its ability to address the environmental issues, in the way off water purification, bio-fuel, bio-ethanol, solar energy (a cost-effective solar energy), more efficient batteries (and pretty much all electronics).

 The next industrial revolution as some have put it...Whether or not I agree... I'll let you know after writing it..

 Sentence is:

" At the same time, some believe nanotechnology to be ‘grey goo’ with caveats of self-replicating nano-organisms destined to conquer and destroy the world."

Have I used caveats in the right way here? If not, and you can see what I'm trying to do, please correct where neccessary. Thanks and lots of love!

(And yes of course you can read a copy of it. I'll post it here afterwards, as it will be public domain in about.. 24 hours anyways :D) 

That sentence was construed (is that the right context?) by me in reference to human perception of negative sci-fi futures..

 How would you re-create that sentence then? I bt you'd do it with so much more grace than mine... Mine sounds rigid... Plus it's incorrect !
