Sustainability communication is entering a more cautious phase. As scrutiny around environmental claims increases, many companies are choosing restraint over visibility. Commonly referred to as “greenhushing,” this trend is reshaping how manufacturers approach communications.
In B2B manufacturing, the reality is more nuanced. Greenhushing is not always a deliberate decision to “hide” sustainability efforts. In many cases, it reflects caution driven by regulatory complexity, legal risk, and fear of overstating progress in a rapidly evolving landscape.
The stakes are rising on both sides of the Atlantic. In Europe, the Corporate Sustainability Reporting Directive (CSRD) and the Packaging and Packaging Waste Regulation (PPWR) are pushing companies towards a more disciplined, data-driven approach. The PPWR, in particular, will introduce stricter expectations around recyclability claims, labeling, and packaging disclosures across EU markets. In the U.S., tariffs, supply chain disruptions, and broader economic pressures require operational focus that often crowds out communications work.
In this environment, caution is understandable. But silence is not a viable long-term strategy.
Silence Creates a Credibility Vacuum
When companies stay quiet, they lose the ability to shape how environmental efforts are understood by their own teams, their customers, and their value-chain partners. That space doesn't stay empty. The companies that say nothing are left trying to rebuild credibility they didn't need to lose.
In packaging specifically, this plays out in concrete ways. Communicating recycled content in metal requires more than a headline percentage. It means explaining how that content is measured, what is included or excluded, and how materials move through collection and processing systems in practice. Without that clarity, even accurate claims can mislead, and procurement decisions get made on incomplete information.
Trivium’s annual sustainability report is an opportunity to move beyond broad claims and provide operational details behind circularity in practice. The 2025 ESG Key Performance Indicators Summary outlines measurable progress, such as an 8% reduction in Scope 1 and 2 emissions compared to 2024 (for a total of 36% reduction since 2020) and highlights that 23% of our sales revenue comes from ecodesigned products, which includes increased recycled content and lightweighting initiatives.
The alternative is not to say more. It is to say things that are substantiated, grounded in data, and specific enough to actually inform decisions.
Grounding Sustainability Claims in Evidence
Life cycle assessment (LCA) data is among the most widely recognized foundations for substantiated environmental communications. An LCA covers the environmental impact of a product across its entire life, from raw material extraction through manufacturing and end-of-life. Critically, it requires being explicit about system boundaries: what is included, what is excluded, and why. That transparency is what separates a substantiated claim from a broad assertion, and increasingly, it is what customers and regulators are asking for.
Metal Packaging Europe's LCA studies are a useful reference point for the industry. The most recent assessment found that aluminum food cans across Europe are now approximately 19% lighter than in previous assessments, steel general line cans 13% lighter, and steel aerosol cans 10% lighter. These figures connect environmental claims to verifiable operational improvements and give value-chain partners something concrete they can use in their own procurement assessments and reporting.
LCA data is key to enabling our customers to have more accurate information about their products’ carbon footprint and how it could impact their decarbonization roadmaps.
Alignment Starts Internally
This same discipline applies internally. How clearly a company articulates its approach directly affects how its own teams prioritize procurement, supplier expectations, packaging recovery targets, and recycling goals. When that reasoning is not communicated well, each function fills the gap with its own assumptions.
At Trivium, the Environmental and Social Claims Policy establishes a shared framework for how sustainability-related claims are evaluated and communicated. By emphasizing accuracy, transparency, specificity, and appropriate comparability conditions, the Policy helps align legal, commercial, procurement, and sustainability teams around a consistent standard for external communications.
Industry collaboration offers another model worth considering. Rather than positioning themselves as isolated leaders, companies that work through shared challenges together tend to produce communication that is more grounded and more impactful.
ALUPRO's UK Aerosol Recycling Initiative (UKARI) is a strong example. Research found that householders are widely unsure how to recycle aerosols, resulting in far fewer containers collected at the curbside than most other forms of metal packaging. Rather than leaving individual brands to address this alone, ALUPRO coordinated a cross-industry response with SUEZ Recycling and Recovery UK.
The initiative began with waste composition sampling at materials recovery facilities in Greater Manchester and the West Midlands to establish a baseline. It then launched a targeted campaign around a single, practical instruction, "shake, spray, squirt," explaining how to recycle empty aerosols and dispose of containers with residual product still inside. The campaign ran across social media, linked to a dedicated microsite, and was supported by signage at Household Waste Recycling Centers.
A parallel effort is underway in the United States. The Can Manufacturers Institute (CMI) and the Household & Commercial Products Association (HCPA) launched the Aerosol Recycling Initiative to address the same fundamental challenge: despite being recyclable, aerosol cans are widely rejected by Material Recovery Facilities due to contamination concerns, infrastructure, limitations, or inconsistent consumer guidance.
The Aerosol Recycling Initiative brings together companies across the aerosol value chain and has produced a practical MRF playbook — developed from interviews with 13 facilities across 11 states — to give operators the tools and shared language needed to expand aerosol acceptance. By 2030, the program aims to achieve at least an 85% recycling access rate for aerosol cans and ensure that 90% carry clear recyclability labeling.
Taken together, these programs illustrate what industry communication can look like in practice: specific, locally targeted, and tied to measurable recovery goals. Practical answer to a real consumer question — and that distinction is what makes them credible.
The manufacturers that will build lasting credibility in this environment are not necessarily the ones making the boldest claims. They are the ones willing to communicate honestly about what they know, what they are working toward, and what the systems around them actually make possible. That is what good stewardship looks like in practice.
