Industrial businesses should move beyond basic data collection and adopt financial-style decarbonisation analysis for evaluating environmental metrics, according to Scott Collick, CSO at DuPont.
DuPont’s Carbon Fluency Framework evaluates greenhouse gas metrics using different factors such as product mass, revenue and unit margin.
This methodology lets sustainability teams assess product footprints from multiple perspectives, rather than viewing emissions as standalone figures.
“At DuPont, we’re constantly looking at all of our product lines using that toggle switch and it gives you very different insight when you toggle between mass efficiency and dollar efficiency,” said Scott during his keynote address at Sustainability LIVE @ CWNYC last month.
Shifting the evaluation from physical weight to economic output provides manufacturers with actionable insights into efficiency across product lines, Scott explained.
“Carbon metrics, just like financial metrics, help make better decisions,” said Scott.
“You can look at it from a product and operations lens. You can look at it from a business and supply chain lens.
“I often get asked this question: what’s the appropriate green premium for products? I’ve seen anywhere from 5 to 50%.
“You guys are asking the wrong question. It’s not the premium, it’s what is it on a cost of carbon?”
Changing denominators in carbon metrics
Evaluating product footprints solely by physical mass does not capture commercially relevant trade-offs or total economic utility.
For instance, a 55kg CO2 footprint reflects different operational realities depending on whether it applies to 10 pounds (4.5kg) of aluminium (350 cans), 2,000 plastic water bottles, 25 reams of paper, or an iPhone 17, Scott said.
Measured by mass, an iPhone 17 has a footprint of nearly 300 kilograms of CO2 per kilogram, indicating low physical efficiency.
However, measured by revenue, its carbon intensity drops to 65 metric tons per million dollars, making it the most carbon-efficient asset in the comparison because of its high value density, Scott explains.
“We, as sustainability professionals, should actually have an inherent sense of what the carbon footprint of our products is.” For instance, a 55kg CO2 footprint reflects different operational realities depending on whether it applies to 10 pounds (4.5kg) of aluminium (350 cans), 2,000 plastic water bottles, 25 reams of paper, or an iPhone 17, Scott said.

Key dimensions of corporate carbon fluency:
Supply chain data and marginal abatement
To track progress, corporate procurement must shift from high-level spend estimates to verified primary data, said Scott.
Corporate buyers face challenges in Scope 3 emissions management, where indirect upstream inputs account for most of an organisation’s environmental footprint.
Scott explained that at DuPont, Scope 3 management uses a hybrid approach: 40% spend-based data, 30% activity-based data, and 30% primary Product Carbon Footprints (PCFs).
“We cannot solve sustainability until we’re all on a PCF basis between companies,” said Scott.
“My goal is to get that to 100% activity-based in two years and over 50% primary data-based.”
Customer demand directly shapes corporate strategy. “We survey our customers; we see by far the number one demand signal coming through is for climate.”
Beyond green premiums to carbon costs
Corporate procurement strategies often falter when they focus on arbitrary product premiums instead of clear marginal abatement cost curves. Financial feasibility requires mapping carbon abatement initiatives to defined per-ton dollar thresholds to ensure capital delivers measurable decarbonisation.
Evaluating green premiums alone distracts executives from establishing clear cost structures per metric ton of avoided emissions.
Projects costing less than US$100 per ton are highly investable, while those between US$100 and US$200 per ton require selective review, said Scott.
“If you’re above US$200 a ton, probably not the best phase,” he notes, “so we gotta move from asking about premiums to asking what it means on a cost-of-carbon basis.”

While nearly a quarter of employers say they consider AI fluency an unrewarded baseline skill, the majority of workers disagree. More than half of the employees surveyed by compensation software company Payscale said they should earn more for developing AI skills, according to a recent report.
A recent exchange on LinkedIn involved a senior leader at McKinsey questioning whether the glass cliff even exists for female leaders at struggling companies. Julia Carreon didn’t anticipate that a LinkedIn post promoting her new book would spark an exchange that made a persuasive case for why she wrote the book in the first place.
I’ve written before about how good leaders give effective feedback when the stakes are high. That article articulates a method for structuring feedback to ensure you effectively deliver the content of your message so that it can be heard and so that it can actually help change behavior going forward.
