Engineers can change the world, but what must change first is engineering itself.
Nearly everyone I encounter accepts that sustainability is an all-hands-on-deck imperative. But not everyone appreciates the extent to which it is fundamentally an engineering challenge.
While fostering a broad-based sustainability culture is absolutely the right thing to do, the truth is that saving the planet requires much more than riding your bike to work and recycling your pizza box. Yes, let’s all do those things. But let’s also understand that, compared to industrial scale polluters and resource consumers, the cumulative impact of individual action is relatively small. Achieving true sustainability requires an examination of our values, a shift in the way we think, and changes to how we act. The attitude of “I’m just doing what the spec says” doesn’t cut it anymore.
Engineers must accept personal responsibility for their work, understanding the deeper footprint, and entire lifecycle of our solutions. In other words, before engineers can change the world, what must change first is engineering itself.
Changing the way engineers are educated, employed, and evaluated is critical to developing the multidisciplinary, environmentally focused, socially conscious technical workforce the world needs to achieve true sustainability. Last year, in my capacity as co-chair of ASME’s Engineering Global Development Committee, I had the privilege of participating in the EGD Stakeholder Summit, one outcome of which was a whitepaper titled, “Engineering Workforce Advancing Sustainable Development.” Among other things, the whitepaper identified six cultural shifts required to achieve what it calls “engineering sustainable development.”
This space doesn’t permit a full exploration of those shifts; for that, you’ll need to refer to the whitepaper. But the key takeaways are these: First, engineers must take an interdisciplinary and multi-stakeholder approach, with the understanding that every engineered solution is part of a dynamic and interconnected system, having potentially wide social and environmental impacts.
The report also urges the profession to prioritize diversity and inclusion, for the simple reason that “a homogenous field is a limited field.” Better solutions inevitably result from more varied perspectives at the table.
Also required is a perception shift that challenges the notion that engineering is neutral. It’s not. “Values shape technology,” the report states, suggesting that design is a series of choices, and choices are informed by bias, conscious or not: Yet another reason why a more inclusive engineering process will produce more responsive—and responsible—outcomes.
The final insight I’ll mention is the most important: the need to “broaden engineering goals to include environmental and social outcomes.” An engineered solution that solves one problem while exacerbating another is not sustainable. The old metrics of technical performance, efficiency, and profitability are necessary but not sufficient. To these we must add the broader impacts a solution will have on the environment, on communities, and on individuals. If an engineered system or product advantages one group of people at the expense of another, then it fails the sustainability test.
Fortunately, this is not news to the engineering students I teach and the early-career professionals I meet in my work with ASME’s EGD programs.
What’s more, many of my former colleagues in senior engineering management roles are also championing these values.
There is a growing awareness across the engineering community that mechanical engineers must adopt a sustainability mindset, must in fact become sustainability engineers. This is already happening. Our task now is to accelerate this transformation.
ASME members can take pride in our Engineering Global Development initiatives, funded in part by the ASME Foundation. These include the one-million-member Engineering for Change (E4C) digital platform; our E4C Research Fellowships; and the ISHOW and IDEA Lab accelerators, which help social entrepreneurs bring sustainable innovations to market.
ASME’s Board of Governors recently adopted a statement on climate action that firmly and officially establishes the Society as a change-agent in the drive toward sustainable engineering. The statement implicitly acknowledges that mechanical engineers bear a disproportionate share of the responsibility for achieving sustainability. It’s a charge a growing number of us are both happy and well suited to fulfill.
