Thinking in Layers

As Corning celebrates 175 years of innovation , we recently spoke with Mark Steen, VP of Sustainability and Climate Initiatives , about the evolving role of sustainability in a global manufacturing business. The conversation explored Corning's philosophy of 'practical sustainability', the business rationale behind environmental initiatives and how sustainability considerations are increasingly shaping innovation, operational decision-making and long-term value creation.

. Corning Incorporated is a 175-year-old materials science company whose products sit inside LCD screens, optical fiber networks, automotive catalytic convertors, mobile consumer electronics, and life sciences laboratories. With manufacturing operations across the globe, including a significant presence in India dating back more than 60 years, the company faces sustainability challenges at every level: regulatory, operational, and strategic. To navigate these issues, Corning has developed a three-layer framework which it buckets as ‘ Regulatory and Reporting’ , ‘ Footprint’ and ‘ Handprint’ . The layers support one another, each unlocking the one above it, and together reflect a sustainability philosophy that is more operationally grounded than most corporate narratives.

. The Three-Layer Framework Corning organises its sustainability work into three distinct but connected layers. Each build on the credibility and insight generated by the one below it, and together they give sustainability a structure that every function in the business can engage with.

Layer 1: Regulatory and Reporting (‘Ticket to Play’)

The first layer is where most companies begin, and many stop: Meeting local environmental and social regulations and reporting against them. Corning treats this as the minimum required to operate, the ‘ticket to play,’ but also as a source of intelligence that most companies leave on the table. Requirements in Europe differ significantly from those in the United States and India, which means the compliance work spans a wide range of reporting standards and disclosure obligations. Rather than treating each as a separate burden, the process of building these reports forces a level of operational scrutiny that most management structures do not demand. While conducting a mandatory energy audit at one of its plants, the team discovered that leaking compressed air lines were costing hundreds of thousands of dollars annually in wasted electricity. The problem had existed for years, invisible simply because no one had a reason to look for it. The fix was sealing the hoses. The cost was negligible. The savings were immediate.

Layer 2: Footprint (‘Managing What You Control’)

The second layer covers the direct impact of operations on the environment and the people working within them, including greenhouse gas (GHG) emissions, waste generation, water consumption and worker health and safety. Approximately 80% of scope 1 and 2 GHG emissions come from electricity consumption rather than from burning fuel, making the carbon intensity of the local grid one of the most consequential variables in a company’s emissions profile. In markets like India, where the grid remains heavily coal-dependent, this creates a real ceiling on how quickly reductions are achievable, regardless of internal ambitions. Corning’s key plan in Pune is actively working to raise the share of solar in its electricity mix, with a long-term aspiration of reaching 100% renewable power, a goal that requires navigating state-level energy procurement regulations. The footprint layer builds credibility: a company that cannot demonstrate serious management of its own direct environmental impact is in a weaker position to sell products that claim to help others reduce theirs.

Layer Three: Handprint (‘Enabling Others to Achieve More’)

While ‘footprint’ measures what the company does to the world, ‘handprint’ measures what it enables others to do through its products. The ceramic substrates inside catalytic converters and diesel particulate filters fitted in vehicles worldwide can make the air exiting the back of a bus measurably cleaner than the air entering the front of it. Corning does not clean the air directly; rather, it manufactures the components that make it possible for millions of customers to do so. Similarly, one of its largest solar-wafer manufacturing plants in the US has a GHG-reduction potential more than five times the total emissions from all of Corning's global operations combined. Even if every ton of direct emissions were eliminated entirely, the climate benefit would amount to less than a fifth of what its solar products can enable others to achieve. Handprint thus reframes where a company's sustainability impact lies and where its commercial opportunity sits.

. Sustainability on the Ground The gap between any sustainability model and actual, plant-floor behaviour is where most corporate sustainability programs quietly fail. Corning's approach to closing that gap rests on the fact that sustainability is not a separate program imposed on operations, but a new lens applied to operations that already exist. The requirement to think about environmental impact provides a new angle from which to find potential improvements that were always there but never visible.

The most resistant audience for this argument is operations leadership. Plant managers are accountable for throughput, cost, and uptime. A proposal to change an established process carries real risk, which lands squarely on them. Corning's response is not to override this resistance, but to engage it differently, arriving at plants not with mandates but with questions: Where are the waste streams? What are the costly processes that have never been examined closely? What would you change if you had a reason to look at it again? What the company has found, repeatedly, is that the people doing the day-to-day work often want to have a larger impact on the world beyond the product they make. When given a framework and permission to think about sustainability, they produce solutions that no central team would have found.

. From Insight to Action: The Innovation Contest and Its Results To channel such solutions, Corning runs a global sustainability innovation contest open to employees across its manufacturing plants. Teams apply for grants to fund sustainability improvements in their own operations, and the winners receive the resources to implement them. The contest is important not just for the ideas it funds but for the signal it sends – the people closest to the process are entrusted to find the solutions. The results bear this out. A plant employee in Poland proposed purchasing equipment that would allow a hazardous chemical solvent, previously procured fresh and disposed of after a single use, to be recycled and reused within the same facility. The application was accepted and the equipment installed. In just four months, the project turned a positive ROI. A four-month payback on a piece of capital equipment is a decision any business would make without hesitation. Yet it was passed over for years, simply because no one had a reason to look for it until the sustainability lens provided one.

The same dynamic has played out in India, where plastic regulations required the company to reconsider the shrink wrap used in its product packaging. Rather than treat this as a compliance cost, the local operations team identified local biodegradable plastic alternatives and made the switch. The solution worked well enough that Corning is now evaluating whether it can be applied in its European plants, where demand for sustainable packaging is growing, but where the same materials are harder to source. A regulatory constraint in India produced an innovation that a more developed market is now looking to import, a useful reminder that sustainability leadership does not always travel in the direction people assume.

. Moving Sustainability to the Core Corning's approach to sustainability is understood through the analogy it draws to quality. Decades ago, under the Houghton family leadership, which defined the company for much of its history, Corning went through a company-wide quality initiative. Over time, quality stopped being a p rogram , instead becoming a value – one of the seven core principles that define how the company operates today. Corning’s sustainability journey is on the same trajectory. The ambition is not to run a sustainability program alongside the business, but to embed sustainability thinking so deeply into operations that it becomes indistinguishable from good management.

Corning has been in business for over 175 years. Getting there has required thinking seriously about sustaining the conditions, the relationships, the environment, and the trust that make the business possible. The next 175 years will require the same.
