The Democratic National Convention (DNC) recently – and quietly – adopted a ban on receiving donations from fossil fuel companies. 
The text of the resolution states that:
“…fossil fuel corporations are drowning our democracy in a tidal wave of dark oily money; they have deceived the public about the impacts of climate change, fought the growth of clean renewable energy, and corrupted our political system.” 
The resolution, which was unanimously approved by the executive committee, bars the DNC from accepting contributions from corporate political action committees (PACs) linked to the gas, oil, and coal industries. 
RL Miller, president of the super PAC Climate Hawks Vote Political Action and a co-author of the resolution, said:
“We talk about how climate change is real and climate change is a planetary emergency, what we need to do is to stop taking money from the institutions that have created this crisis.”
When the DNC’s full board meeting rolls around in August, the organization may consider a second resolution that would ban contributions over $200 from people who work in the fossil fuel industry. Miller said such a resolution would hopefully lead candidates to adopt similar measures.
“So, if Eddie Exxon is your college buddy and a frat-boy friend of yours and he’s employed at an Exxon gas station and wishes to donate $25 to have a barbecue and a beer with you, fine. But if Edward J. Exxon in Exxon’s middle management thinks you’re worth contributing $2,700 to out of his own salary, that is much more concerning to us.”

It was just a little over a year ago that regular DNC members rejected a proposal introduced by Christine Pelosi to ban “registered, federal corporate lobbyists” from serving as “DNC chair-appointed, at-large members,” and to reinstate former President Barack Obama’s ban on corporate PAC donations. 
Under the Obama-era ban, contributions from PACs and lobbyists were banned, but the ban was lifted ahead of the 2016 election by former DNC chair Debbie Wasserman Schultz.
In 2016, energy and natural resource sectors donated $2.6 million to the DNC, data collected by the nonpartisan Center for Responsive Politics showed. As of mid-May, the DNC had collected $186,100 from the energy and natural resource sectors.
Also in 2016, oil and gas companies shelled out a whopping $7.6 million to support Democratic races.
So far this year, Republicans have raked in 89% of the energy industry’s donations. Two years ago, the coal mining industry gave 97% of its donations to Republicans.
