Scientists Say They Can Calculate the Cost of Oil Giants' Role In Global Warming (washingtonpost.com) 112

An anonymous reader quotes a report from the Washington Post: Oil and gas companies are facing hundreds of lawsuits around the world testing whether they can be held responsible for their role in causing climate change. Now, two scientists say they've built a tool that can calculate how much damage each company's planet-warming pollution has caused -- and how much money they could be forced to pay if they're successfully sued. Collectively, greenhouse emissions from 111 fossil fuel companies caused the world $28 trillion in damage from extreme heat from 1991 to 2020, according to a paper published Wednesday in Nature. The new analysis could fuel an emerging legal fight.The authors, Dartmouth associate professor Justin Mankin and Chris Callahan, a postdoctoral researcher at Stanford University, say their model can determine a specific company's share of responsibility over any time period. [...]

Callahan and Mankin's work combines all of these steps -- estimating a company's historical emissions, figuring out how much those emissions contributed to climate change and calculating how much economic damage climate change has caused -- into one "end-to-end" model that links one polluter's emissions to a dollar amount of economic damage from extreme heat. By their calculation, Saudi Aramco is on the hook for $2.05 trillion in economic losses from extreme heat from 1991 to 2020. Russia's Gazprom is responsible for $2 trillion, Chevron for $1.98 trillion, ExxonMobil for $1.91 trillion and BP for $1.45 trillion. Industry groups and companies tend to object to the methodologies of attribution science. They could seek to contest the assumptions that went into each step of Mankin and Callahan's model.

Indeed, every step in that process introduces some room for error, and stringing together all of those steps compounds the uncertainty in the model, according to Delta Merner, lead scientist at theScience Hub for Climate Litigation, which connects scientists and lawyers bringing climate lawsuits. She also mentioned that the researchers relied on a commonly used but simplified climate model known as the Finite Amplitude Impulse Response (FAIR) model. "It is robust for the purpose of what the study is doing," Merner said, "but these models do make assumptions about climate sensitivity, about carbon cycle behavior, energy balance, and all of the simplifications in there do introduce some uncertainty." The exact dollar figures in the paper aren't intended as gospel. But outside scientists said Mankin and Callahan use well-established, peer-reviewed datasets and climate models for every step in their process, and they are transparent about the uncertainty in the numbers.

    Isn't consumption the problem, rather than production? As far as I can tell, basically all human systems across the globe now depend on oil. Doesn't that make us all complicit? And there is no way these oil companies will pay anything without passing that content on to the consumer. We're not going to get off oil, IMHO. Isn't it the most financially valuable resource on the planet (excluding real estate - maybe)? With water as the actual most valuable resource?

      The main role of oil companies in global warming has been that they had set up a large and well-funded campaign to dismiss or discredit climate science, using lessons learned from the campaign by the tobacco industry decades earlier to attack the science showing the health effects of smoking. It's important to remember that the oil companies are not mere billion-dollar industries; they are a multi-trillion dollar industry, and even small changes in oil consumption represents billions and billions of dollars.

      The worse problem here is that the campaign to attack the science has bled over into other areas; science denial is rampant in our society, from flat-Earthers to moon-landing deniers to pretty much all of modern science.

Because if you massively fine them for selling oil products the first thing they are going to do is stop selling those oil products into whatever state or country which enacts those fines. It only make sense, if you are incurring massive fines the very first thing you should do is to stop accruing even more fines from continued shipment.

          The oil companies can try crippling nation states if they want to, but I suspect that they will find the consequences rather severe.

          The best way to do it would be some hefty fines now and a new tax regime that strongly encourages profits to be invested in reducing reliance on oil. The oil companies can then choose - no profits, or they invest in profitable alternatives and secure their futures.

        • >> the first thing they are going to do is stop selling those oil products

          More than 65% of oil is used for transportation fuel, and that can largely be eliminated with electric vehicles. And then there's methane, which the oil companies routinely flare or dump into the atmosphere.

          All the information is out there. In massive amounts. I'll recommend starting with the IPCC-WG-1 report, "The Physical Science Basis of climate change [www.ipcc.ch]", but there are plenty of other sources. The Berkeley Earth [berkeleyearth.org] page is also good; try their "Skeptic's Guide" [googleapis.com]

      Keep in mind: oil/gas producers also are enormous consumers of the same energy, and there are lots of emissions from their operations. Drill rigs, pump jacks, refineries, pipelines, and tankers aren't powered by pixie dust. Depending on whose numbers, which fuel, and what country you're talking about, each unit of fossil fuel energy takes 0.02 to 0.50 units of energy to produce. Gas wells and pipelines leak methane. Gas flaring is not benign. Oil

      Yes, consumption generates the pollution and the producers are just doing what makes them money.

      However, we shouldn't blame consumers when:
      Most of the time they don't have a choice to not burn fossils.
      EVs are cheaper to run but more expensive to build and the fossil industry has spent billions on buying politicians to keep EVs out of the hands of consumers. Same with heating your house (fossil NG vs. heat pumps).
      Same with the electricity you buy (barriers to wind and solar PV vs electric utility lobbyists).

  • ...and how much money they could be forced to pay.

    A more accurate headline would be: "Climate activists devise a way to justify more taxes on the population by arbitrarily assigning blame on energy companies."

    The end result will be more expensive energy costs and nothing else.

        Carbon taxes are the worst kind of taxes - they are regressive (i.e., poor impacted the most), they kill jobs (i.e., industry very sensitive to energy costs), and most importantly they do nothing to reduce global emissions as it just shifts production elsewhere. Just look at UK, Germany and so on - they committed economic suicide and achieved none of their stated goals.

            Carbon taxes are also play heavily into housing construction, as both material costs and shipping of materials affected. This results in more expensive homes, which puts downwards pressure on quality of construction as people simply cannot afford to pay more for new homes. This results in cheaply built houses on cheap land (e.g., flood prone) that are a lot more vulnerable to various climate events. So yes, carbon taxes are about the worst thing a government could do to promote resilience.

              There is a push here to increase the required energy efficiency of new homes through building codes. We also have a massive housing shortage and increasing the cost of new builds only makes it worse. Folks are going to have to choose which is the more pressing problem, and they seem ill-equipped for the task.

              Aside, when I was redoing roof on my house I specified high-wind resistance shingles. They cost only slightly more than regular shingles. While not as good as a metal roof, it does get you most of the way there in terms of storm resilience.

Money spent on adaptation gives instant, obvious results. Money spent on mitigation has no noticeable results. Sure, I'll make a contribution to the latter, but that is not where the majority of my money is going to go, regardless of what my stupid government wants.
