Joining the evil team
Hire some fishing boats, and very deep nets. Under the guise of going fishing on extremely endangered species, begin sabotaging underwater communication lines. Additionally, sabotage DNS systems.
On a side note; drilling oil is outdated. Begin construction of a series of nuclear power plants* that process coal/ natural gas and raw biomass straight into oil.
*These plants use a single circuit cooling system. Water is taken in, through the reactor , through the turbine, and back out, taking any radiation with it.
So having your own ideals now makes you evil? I see how it is.
You create said nuclear facilities, damaging the environment while producing oil. I'd say oil in itself is pretty outdated, but whatever. You're not going to power spaceships using oil, are you? You also sabotage underwater communication lines, but that barely hinders global communication.
Begin sending the Sunshine Militia through an intense training regimen.
Capture dolphins and perform experiments on them, the goal of the project is to make dolphins who are loyal to us and have small laser guns in their head to kill the enemy.
Send fifty of the best Sunshine Militia to infiltrate and destroy the Granola Jack Jack inc.
Team: Earthlings
Your and GWG's efforts turn a part of the militia into proper soldiers. You also train a bunch of dolphins for warfare. The operation against Granola Jack Jack inc. is only a partial success, the company can barely manage itself now because of the damage you caused.
((Its funny how the defenders more actively work for the destruction of earth than the destroyers))
+1 for 10ebbor10s suggestion. Construct a research lab, and hire said biologists. Let them research epidemics. Hire a world wide renowned lawyer with low morals
You construct a research lab and the scientists manage to create a disease that now ravages the population. Making a vaccine might not be difficult, however.
Recruit 500 elite soldiers and 3,000 less elite soldiers
Edit:S.A.D.I.S.T.
You recruit some people to your cause. Recruitment is not as easy as it is for the defenders, but your side gets only the best psychopaths into the army, ready to fight for destroying the Earth, while theirs are just a bunch of people who don't want to lose their homes and lives.
Earthlings:
Train militia into a proper army, making sure they all have fairly good weapons. Firearms, at least; this isn't 10th Century England.
Use the militia to take over the enemy mining and drilling facilities located on Earth.
You train some of the militias to become actual soldiers. You fail to destroy any industrial facilities, but you manage to bring down Granola Jack Jack inc.
Co-operate with local human governments to get restrictive Ecology Preservation laws passed to harm current and future enemy business and attempts at harming the environment. Use all means to convince the governments to do so, including threatening with the Sunshine Militia and Bribing with oil.
If any metal or oil is left over at the end of the turn use it to improve Mining Facilities
Sunshine Squad!
The governments of the world don't want to... you know, be destroyed, so they gladly cooperate with the Sunshine Squad. The environmental protection laws are now in effect and GJJ inc. is brought down once and for all. You improve the mining facilities aswell.
Stage anti-austerity protests. Global warning is a lie, and all that stuff. Economical development should be top priority.
Open the book about the Sunshine squad. Discredit them in any way possible. This should not be very hard.
S.A.D.I.S.T.
The anti-austerity protests are only a partial success, due to the new laws implemented by most of the world's countries. With the book however, you expose the bribes and threats the Sunshine Squad was making in order to implement said laws. Some of the militias desert and people become less supportive of them.
Begin purchasing weapons and equipment
You think anyone's gonna sell weapons to a group of people who want to destroy the planet? You'll have to make and research weapons yourself if you want to get anything done.

S.A.D.I.S.T.
point out in Super-freakanomics, global warming was pointed out to be actually be a lie, created by people like Al-gore. Who some are paranoid, very ignorant to science,or just driving up fear for profit or weakening us and preparing an alien invasion, probably just for profit , also that all the destruction you will cause will just be air polluting, killing off earth's breathing supply until those bacteria that oxygen is deadly too come and replace life, in millions of years. Also make sure that humanity will find someway to counter it.
Oh, yes... Yes... This is exactly the kind of stuff I was hoping for...

Same, but to SADISTS.
With that kind of name...well, people have seen James Bond.
The book exposes SADISTS and their plans, but doesn't cause desertion among their ranks. Their ranks are filled with psychopaths who want to see everyone else dead anyway.
Join whichever team has less members at present.
See what the current tech level is.
Screw it.
Join SADISTS. Spare no expense in gathering team of top military equipment designers. Design a new tank superior to pretty much anything the Earthlings have at present.
Order construction of factory to begin construction of these tanks.
The tech levels were until recently pretty much at modern day levels, just FYI. Tanks? Well, once the planet gets blown up they won;t be of much use and the facilities aren't exactly safe of Earth itself. But you create plans for new SADISTS Tanks. The factories are constructed too. The tank production drains the metal production, however.
S.A.D.I.S.T
Start developing stealth technology and capability. We must have stealth soldiers to better help them fight.
You invent proper stealth suits! Pretty early models, though. Not flawless by any means, but they'll do the job for now.
There are other ways of destroying the planet, more reliable than just damaging the environment. What caused many mass extinctions in the past again? Chipping away at the planet's mass may also prove rather effective. But that requires advanced weapons which are not available at the moment...
