If you actually read the article you’d know it names several things that he could then do, and it even links a 55 page pdf report called “THE CLIMATE PRESIDENT’S EMERGENCY POWERS: A LEGAL GUIDE TO BOLD CLIMATE ACTION FROM PRESIDENT BIDEN”

Here is just one of the paragraphs in the article talking about what he could do:

Biden could end new drilling leases on federal lands and waters, block new pipelines and effectively ban fracking. He could unleash a historic education program to counter fossil fuel industry disinformation, using the bully pulpit to build awareness and support. He could prohibit government financing of overseas fossil fuel infrastructure, end energy department fossil-fuel financing programs, ban new fossil-fuel vehicle sales by 2030, prosecute violations by fossil fuel polluters, commit to veto laws granting immunity to such criminals, and more.

Congress won’t do shit with it’s current makeup, and to actually get the numbers of reps needed who actually believe in climate change action will take years (if people even vote them in); too long for action we need to take YESTERDAY.
