Ethical Aspects Of Engineers And Climate Change

Ethical Aspects Of Engineers And Climate Change

Few topics engender as much heated discussion as climate change, and this holds true within the engineering community. Despite the complexity of the science and the variety of opinions—both informed and partisan—the potential consequences of anthropogenic climate change are so severe that it is unethical for engineers to ignore.

Let’s say, hypothetically, that certain activities are identified as causing long-term problems for human health and welfare. These activities involve engineering, as nearly every human enterprise does. What would be our response? Examples exist: the use of lead in water pipes and gasoline; acid rain resulting from sulfuric acid discharged from power plants; CFCs in refrigerants diminishing the earth’s protective ozone layer. All are practices that have changed. Regulatory action did not occur until evidence showed a clear cause-and-effect relationship. These actions met opposition from those with an interest in maintaining the status quo. But eventually, concern for the common good won out.

Anthropogenic climate change (ACC) is somewhat different, as the scale is so much larger. For some, the concept that emissions have increased planetary temperatures and are causing global climate disruption seems unbelievable, with potential future scenarios including escalating temperatures, severe droughts, sea-level rise measured in feet, increased storm intensities, and worsening flooding.

The diverse sources of global warming gases represent virtually every segment of society, including transportation, building construction and operations, food production, manufacturing, energy and water systems, and household behavior. A comprehensive solution involves modifying all these systems and more. To many, this task is unimaginably daunting. Climate science is a complex field. It makes structural engineering (my professional arena) seem simple by comparison.

Critical, disciplined scientific debate is appropriate and necessary — such is the nature of robust science. However, the basics of ACC are well established: The US emits nearly 20 million tons of CO2-equivalent greenhouse gases into the atmosphere every day. The amount of atmospheric CO2 has increased about 50% since the mid-1800s, from an average of about 270 ppm for the past 800,000 years to about 410 ppm today, according to the Environmental Protection Agency. CO2 gas absorbs infrared radiation from warm bodies, such as the earth, and heats up. This is the definition of a greenhouse gas.

Methane (CH4), nitrous oxide (N2O), and fluorinated gases are more potent greenhouse gases than CO2. The amounts of these gases in the atmosphere, according to the EPA, have also significantly increased since the 1800s. The earth’s average land and ocean surface temperature has increased by about 2 degrees Fahrenheit over the past 100 years. Since the start of global temperature tracking in the late 1800s, the warmest years recorded have been 2014, 2015, and 2016, according to the National Oceanic & Atmospheric Administration. No natural "forcing," such as solar output or volcanoes, correlates with the global temperature increase.

The increase in anthropogenic greenhouse gas emissions, according to NASA’s Goddard Institute for Space Studies, is a strong correlation. Engineers are not climate scientists. We use available, credible scientific concepts to advance the public welfare. Many are not sure what to believe. Here’s my take: A very large majority of climate scientists accept the basic tenets of ACC.

ACC is causing problems that will significantly worsen over time. This reality needs our expertise. To supplant fossil fuel combustion with other forms of energy and reduce energy usage calls upon the talents of the entire spectrum of engineering fields. In addition, the manufacture of certain materials is another source of significant emissions. This includes the production of Portland cement clinker, which is the basis of the concrete used in nearly every infrastructure and building project.

Others, such as some hydrochlorofluorocarbon used in refrigerants and blowing agents for some types of rigid and spray-foam insulation, are over a thousand times more potent than carbon dioxide, and, unlike simpler compounds, never break down in the atmosphere—they continue their global warming effect for thousands of years.

We, as engineers, possess the ingenuity and problem-solving capacity to reduce the emission of CO2 and other global warming gases into our atmosphere. The climate scientists have done their part. It’s our turn to act. To dismiss or ignore this situation is to deny the deepest and truest nature of our calling as engineers. The answers can and will come from within our profession. Now more than ever, the world needs us all to be the best engineers that we can be.

The ethical responsibilities of engineers concerning climate change are profound and urgent. Given the scientific consensus on human-induced global warming and its potentially catastrophic impacts, engineers have both a moral obligation and a professional duty to contribute to mitigation efforts. This paper explores the ethical dimensions of engineering practice in relation to climate change, emphasizing the importance of proactive engagement, innovation, and adherence to sustainable principles.

Historically, engineering advances have significantly improved human life but have also contributed to environmental degradation. The use of lead in water systems, CFCs, and fossil fuels exemplify past practices that caused harm, which regulatory actions subsequently addressed. Today, climate change presents a more complex challenge due to its scale, involving multiple sectors such as transportation, construction, manufacturing, and household activities. These sectors collectively emit vast amounts of greenhouse gases, notably CO2, methane, nitrous oxide, and fluorinated gases. The rapid increase in greenhouse gases since the Industrial Revolution has significantly altered Earth's climate, with observable effects including rising temperatures, sea level rise, and increased storm intensity.

From an ethical perspective, engineers must recognize their role in both contributing to and mitigating climate change. The core principles of engineering ethics—safety, sustainability, and public welfare—mandate that engineers do not turn a blind eye to the environmental consequences of their work. The concept of professional responsibility implies that engineers should advocate for cleaner energy sources, improve existing systems, and develop innovative technologies to reduce greenhouse gas emissions. Such actions align with the virtue of social responsibility, emphasizing the engineer's duty to serve society’s best interests.

Many engineers may feel overwhelmed by the scale of the problem, believing that individual or even organizational efforts are insufficient. However, ethical practice encourages a mindset of stewardship and innovation. Engineers possess unique skills and problem-solving abilities that can be harnessed to create sustainable infrastructure, develop renewable energy technologies, and enhance energy efficiency. For instance, engineers have pioneered the development of solar panels, wind turbines, and energy-efficient materials, demonstrating that technological innovation is a vital component of ethical climate action.

Furthermore, the ethics of transparency and accountability require engineers to communicate environmental risks and advocate for policies that address climate change. Engineering codes of ethics, such as those from the National Society of Professional Engineers (NSPE), explicitly emphasize safeguarding the public health and welfare. This ethical obligation extends beyond compliance; it necessitates proactive leadership and advocacy to influence policy, promote sustainable practices, and educate clients and the public about environmental impacts.

In addition to technical contributions, ethical engineering entails reflective practice — evaluating the environmental consequences of design choices and seeking alternatives that minimize harm. For example, choosing sustainable materials over traditional practices, designing energy-efficient systems, and considering lifecycle impacts are integral to ethical decision-making in engineering.

Admittedly, challenges exist, including economic pressures, regulatory frameworks, and resistance from stakeholders invested in traditional fossil fuel industries. Nonetheless, navigating these obstacles ethically involves advocating for a transition toward sustainable practices, investing in research and development, and fostering collaborations across disciplines and sectors.

In conclusion, the ethical responsibilities of engineers regarding climate change are unequivocal. The profession must embrace its role as a steward of societal well-being, leveraging its ingenuity to innovate and implement sustainable solutions. By doing so, engineers uphold the fundamental principles of their profession, supporting the global effort to curb climate change and protect future generations. The time for action is now, and ethical engineering is central to achieving meaningful progress in mitigating this existential threat.
