Not sure if it helps, but JNR (Steam name, not sure if active here) has done a mod changing deforestation:
https://steamcommunity.com/sharedfiles/filedetails/?id=1868147338&searchtext=deforestation
Following the mods description I don't think that the changes made would be possible without having access to the formula, but I'm no modder![]()
Thanks for the mod reference, @Pfeffersack, the description looked promising, so I ran a test game with it

The mod aims to introduce more deforestation stages and make the effects more severe. So I ran the game with no other changes, unchanged victories.xml and Expansion2_victories.xml files, the only gameplay change was this Deforestation mod.
And as soon as I noticed that industrial pollution has started, I was greeted with this screen - 100% deforestation factor right of the bat, up from 0%, t205:
Spoiler :

But then, t292, it goes down to 75%:
Spoiler :

the world has already sunk, btw:

And to 50% t320:
Spoiler :

So I wasn't dreaming or imagining things that time, they did screw up the Deforestation formula in such a way that it goes in reverse now. And it is not exposed, as the mod author, apparently, could only tweak the modifier values.

It was after the update 1.0.1.501 - first update of the NFP - what a disaster pack this turned out to be...
Btw., fun fact: I could not believe my eyes when each and every AI went for Nanotechnology and Mars mission after the Lunar Landing.
And then I realised what was the reason - the random end of the tech tree, the Future era, put Smart Materials behind Nanotechnology, with Nt as a prerequisite. Still, timing wise, nothing impressive: Gilga won SV t331, with 2 Lagrange lasers and 3 ly/t speed, as he did not have more aluminium.
