Abstract

CO2 contributions - Sherco Generating Station - Photo by Tony Webster from Minneapolis, MinnesotaJudgments of moral responsibility should be informed by both scientific analysis and societal standards. Society distinguishes responsibilities into positive and negative, general and special, and backward-looking and forward-looking. Ekwurzel et al. in Clim Chang 2017 shows that 90 major carbon producers have contributed most of the atmospheric CO2 emissions. Once it became clear no later than the 1960s that continuing CO2 emissions would progressively undermine the climate, the major carbon producers could see that they were marketing harmful products. The simple and merely negative responsibility to “do no harm” required them to reduce that harm rapidly either by modifying the product in order to capture its dangerous emissions or by developing safe substitutes to perform the same function, that is, by developing non-carbon-based forms of energy. The seriousness of the harms brought by climate change made this responsibility especially compelling. Ceasing to contribute to harm includes ending exploration for additional fossil fuels. The half century of failure by corporate carbon producers to reduce the harms caused by their products now gives them additional responsibility to correct the damage done by their decades of neglect of the underlying negative responsibility. If major carbon producers also wish to fulfill the general responsibility to make more than a minimal positive social contribution, their distinctive capacities of political power, wealth, and expertise qualify them for leadership in the transition to an energy regime that would be safe for future generations to rely on.

Carbon producer CO2 contributions and the energy transition

The article this accompanies is the third in an important series. The foundational analysis of the contributions of major carbon producers to atmospheric CO2 emissions and methane emissions was the first to appear (Heede 2014), followed by a rich and concrete analysis of the moral responsibilities of the major carbon producers in light of those contributions (Frumhoff et al. 2015). This third analysis not only refines the calculations of the contributions of major carbon producers to atmospheric CO2 and methane emissions but also expands the calculations to include the contributions of those same producers to global mean surface temperature and global sea level (Ekwurzel et al. 2017). It correctly, and modestly, observes: “Assigning responsibility for climate change is a societal judgment, one that can be informed by but not determined through scientific analysis”.

Fortunately, society has inherited from centuries of ethical reflection a straightforward system of concepts to use in making such judgments carefully, systematically, and nonarbitrarily. Failures of responsibility—in this article, always meaning moral responsibility, leaving aside important issues about legal responsibility—may, for example, be divided into “sins of commission” and “sins of omission.” In a closely related way, the responsibilities may be divided into “negative duties”—duties not to act in certain ways—and “positive duties”— duties to act in certain ways. “Responsibility” and “duty” are often used interchangeably. One can think of a “sin of commission” as the violation of a negative duty, or responsibility, and of a “sin of omission” as the violation of a positive duty, or responsibility.

Other conceptual distinctions similarly provide basic orientation. Responsibilities are usually divided into general and special. A general responsibility may be owed to all human beings, so that any human that one can affect may be entitled to one’s fulfillment of the responsibility. General responsibilities may also be owed to all members of much broader groups, for example, all sentient beings, or all living beings. A special responsibility, by contrast, is owed to only some others: those with whom one has some special relationship. Special relationships come in many varieties. Someone might be a relative (of various degrees of closeness), or a customer, or a stockholder, or a creditor, or a benefactor, or someone to whom a promise was made, or someone toward whom a promise was broken. Often, the nature of the special relationship largely dictates the content of the special responsibility—what a friend owes differs from what an employer owes.

Special responsibilities tend to be additive to general ones: one owes one’s daughter everything that one owes any human being, but much more besides. And additional responsibilities arise as the consequence of failures to honor underlying responsibilities. Once either a special or a general responsibility is betrayed, that underlying responsibility may well remain, but it will then be accompanied by secondary responsibilities, specifically to those affected by the failure, to reverse the bad effects of the betrayal and/or secondary responsibilities to compensate for the initial damage. A promise broken brings additional responsibility beyond the promise originally made.

Another common distinction is between backward-looking and forward-looking responsibilities. As the names suggest, a backward-looking responsibility is based on something that has already occurred. These too come in various kinds, one of which is some kind of betrayal of a special relationship, like the broken promise just mentioned, or a past failure to provide for a daughter something that was owed to her by a parent. A different kind of backward-looking responsibility rests on causal responsibility, or contribution: “clean up your own mess” or, more elegantly, “responsibility for a problem is assumed to fall on those who create it, particularly if they do so knowingly” (Frumhoff et al. 2015).

Forward-looking responsibilities, by contrast, rest on opportunity, not blame. One has responsibility to act, not because one has caused a problem or has any other prior connection, but because one is in a position, or has the capacity, to improve the situation. The “Good Samaritan” in the New Testament parable had not knocked the other man into the ditch. He simply had the ability to help him out. It was not his problem, but it was his opportunity. Positive forward-looking responsibilities, since they may impose some Climatic Change burden or cost on their bearer, must obviously be owed to a limited number of people. Otherwise, one would be bound to continue to solve other people’s problems until all one’s time and resources were exhausted, and one would have turned oneself into a tool entirely in the service of others with no life of one’s own. By contrast, negative forward-looking responsibilities—for example, do no harm—hold all the time toward everyone. What economists like to call “opportunity costs” do not figure in this moral calculus—otherwise, every negative responsibility would seem to be a costly positive responsibility because of opportunities forgone and could then be evaded.

Most concrete responsibilities can be characterized using a number of these conceptual distinctions. For example, one bedrock principle of morality is “do no [unnecessary] harm.” The responsibility not to inflict avoidable harm is a negative, general, forward-looking responsibility: negative, because all that is required is not to do something; general, because it is owed to anyone; and forward-looking, because it is based on what may happen in the future, not on anything that has already occurred in the past. “Clean up your own mess,” on the other hand, while also a bedrock principle, is positive, special, and backward-looking: positive, because what is required is performance of the actions necessary for the clean-up; special, because it is owed specifically to those currently suffering from the mess caused; and backward-looking, because it is based on one’s causal role in creating the mess. Strikingly, “do no harm” and “clean up your own mess” are the two sides of the same coin: those who fail to fulfill the first responsibility ordinarily incur the second responsibility. If one does contribute to harm, in violation of the negative responsibility, it becomes one’s positive responsibility to correct it—and perhaps compensate for it as well. The preceding is more than enough conceptual background against which briefly to reflect further on the responsibilities of the 90 major carbon producers.

There is nothing wrong—nothing blameworthy—in general about exploring for a product, extracting it, transporting it, refining it—or manufacturing it, in the case of cement—and selling forms of it to people who want to buy them. The study demonstrates what it calls the “contribution” of the 90 producers—83 of coal, oil, and natural gas and 7 of cement—to CO2 and CH4 emissions and, as a consequence of the climate forcing by these emissions, to global mean surface temperature and global sea level. This demonstrates, strictly speaking, causal responsibility. But causal responsibility does not entail moral responsibility (Müller et al. 2009). If A falls down the escalator because she is hit from behind by B, but B was tripped by C, B is partly causally responsible but not at all morally responsible for A’s fall. The moral responsibility for A’s fall belongs entirely to C. Causal responsibility must be blameworthy to become the basis for moral responsibility, and causation—or “contribution”—is blameworthy only if it is a violation of a socially accepted principle. What principle, if any, have the 90 producers violated? What might they consequently be responsible for?

What is remarkable is how utterly basic and elemental are the responsibilities that have been and continue to be violated. By continuing major contributions to harm, the major carbon producers have for decades knowingly and flagrantly persisted in violating the bedrock principle: do no harm. In the beginning of the carbon energy era, very few people understood that CO2 emissions progressively undermine the stability of the climate as they accumulate in the atmosphere. The cumulative atmospheric concentration of CO2 had been building since early in the Industrial Revolution, but as long as its harmful effects in disturbing planetary processes were not widely appreciated, it was not blameworthy to continue to make the concrete and sell the fossil fuels. (The often fatal health effects of the air pollution from burning coal were understood earlier, but coal is the worst case.)

By 1965, however, the US President was saying in a special message to Congress: “this generation has altered the composition of the atmosphere on a global scale through radioactive materials and a steady increase in carbon dioxide from the burning of fossil fuels” (Jamieson 2014). Later in 1965, the President’s Science Advisory Committee issued a report treating CO2 as a pollutant, with an appendix on “Atmospheric Carbon Dioxide” (US, White House 1965). And scientists working for carbon producers were among the first to begin to grasp the significance of CO2 emissions (Banerjee 2015). In 1978, Exxon scientist Black noted: “present thinking holds that man has a time window of five to ten years before the need for hard decisions regarding changes in energy strategies might become critical” (Black 1978).

The situation changes radically as soon as one thus realizes that a product one is marketing is harmful, especially when the harm is of the monumental magnitude of progressively undermining the climatic processes that are the pre-conditions for human societies and the economies that sustain them. The historical case of the Little Ice Age demonstrates what chaos and conflict can result from the “fatal synergy” between a mere one degree of climate change (downward) and other intersecting sources of social stress (Parker 2013). Since twentieth century economies needed energy and concrete, it would of course have been impossible simply to stop selling these products immediately when their effects on the climate became predictable. Necessity is an excuse for temporary harm, provided one works energetically to escape the necessity—where the harm cannot immediately be avoided, it ought to be eliminated as rapidly as possible. How, then, does the producer of a harmful product move into compliance with the (negative, general, forward-looking) responsibility to do no harm? By the same two obvious measures that are always available: move aggressively to find non-harmful substitutes that perform the same function insofar as the need for the function cannot itself be reduced, namely, develop non-carbon energy, and pursue robust research into ways to make the old products safer, for example, carbon capture and storage. Modify or substitute in order to stop contributing to harm. This is not complicated or controversial and is a widely shared social judgment.

About the Climatic Change Journal
link.springer.com/journal/10584
Climatic Change is dedicated to the totality of the problem of climatic variability and change – its descriptions, causes, implications and interactions among these. The purpose of the journal is to provide a means of exchange among those working in different disciplines on problems related to climatic variations. This means that authors have an opportunity to communicate the essence of their studies to people in other climate-related disciplines and to interested non-disciplinarians, as well as to report on research in which the originality is in the combinations of (not necessarily original) work from several disciplines. The journal also includes vigorous editorial and book review sections
