Bernie might make for a interesting college prof, but presidential?! Lolololol
I want to raise awareness of a couple of issues related to pollution and industrial manufacturing, particularly as it relates to oil & gas (upstream, midstream, and downstream) and chemical manufacturing.
I've participated in that industry, working in different areas. I've been offshore, and I've been in every possible chemical and power plant that I could in Louisiana. First off, climate change associated with carbon emissions is recognized as something that exists by the industry, particularly by the Shell Group Chief Scientist. The best ways to mitigate climate change and reduce carbon emissions, as I was taught by that industry, would be to put a price on carbon emissions and to minimize coal consumption while maximizing natural gas consumption. I'm not even trying to interpret or judge any of that, just reporting on exactly what I was instructed in as a member of that industry.
The most important thing to Oil & Gas (O&G) and to chemical manufacturing is License To Operate (LTO), and LTO is a function of reputation. Every one of the big players has a super-robust Health, Safety, Security, and Environment (HSSE) organization and goals, as well as Social Performance (SP) organization and goals. Shell for example, had (still has) "Goal Zero" of no harm to people or environment. It's not perfect, and no organization will be, tbut he effort and interest in minimizing emissions and pollution is present and genuine. Your Super-Majors and other big players have a general standard of having stricter policies and procedures than those implemented by the governments where they operate. That's not always been the case, at all, but I think it's important to have generally accurate idea of what modern industry is really like.
I take exeception to the idea that it's profitable to pollute (it's not) and that O&G and chemical manufacturers, are waiting for or eager for a relaxation in governmental regulation so that they can pollute.
As a random type of example, there was an oil field in Africa in the middle of a national forest. The wildlife inside the oil field area was more populous, healthy, and diverse than inside the national forest.
