But now that I’ve found out they’re still lying and covering up their role in climate change and the size of their own carbon footprint, I’m going to have to get tougher with them. I initially gave Exxon/Mobil till 2020 to get out of Torrance and clean up their toxic mess here in my town.
These companies believe that accelerating investment in hydrogen will help the US deliver on its climate goals while creating a stronger economy with new, good-paying jobs. policymakers and other stakeholders to accelerate adoption of hydrogen solutions and related infrastructure build-out across the nation.
The Greenius understands full well this “ Let’s Keep Lindsey Graham and Joe Lieberman Aboard the Climate Bill Bandwagon &# approach, just as I can grok how ineffective and nonproductive that approach is. That climate change will be even worse by the time this dead dinosaur fluid gets pumped out of the ground.
Stuart Licht, a chemistry professor at the George Washington University, and his team of researchers are among the finalists announced today in the $20-million Carbon XPRIZE competition.
