6 terms

environmental product declaration regulatory

"announced the launch of its environmental product declaration (EPD) tool"

A certified report that quantifies a product’s environmental impacts across its life—from raw materials and manufacturing to use and disposal—often verified by an independent reviewer. Think of it as a nutrition label for a product’s carbon, resource and waste footprint; investors use it to judge regulatory and reputational risk, alignment with sustainability demand, and whether a product’s supply chain pressures could affect future costs or sales.

international epd system regulatory

"declarations under the International EPD System. EPDs are a globally recognized"

An International EPD System is a global program that verifies and publishes standardized Environmental Product Declarations (EPDs), which are third-party reports summarizing a product’s lifecycle environmental impacts—like carbon, energy and resource use—using agreed rules. For investors, these declare how transparent and credible a company’s environmental claims are, helping assess regulatory risk, product comparability and long-term demand for greener products much like a nutrition label helps compare foods.

life-cycle-based technical

"environmental impacts of a product using a life-cycle-based framework aligned"

An approach that evaluates a product, project, or asset by its stages from development through maturity to decline, and uses that timeline to guide decisions like spending, pricing, and regulatory steps. For investors, it signals expected costs, revenue patterns, and risk at each stage—like checking a plant's growth cycle to know when to water or harvest—so you can judge timing, returns, and whether management plans are realistic.

iso-14025 technical

"framework aligned with ISO-14025, -14040, and -14044, together with"

An international standard that sets rules for creating verified, third-party environmental product declarations (EPDs) that report a product’s measurable environmental impacts across its life cycle. Investors use these declarations like a nutrition label for products—offering comparable, audited data on resource use and emissions that helps assess a company’s environmental performance, supply-chain risks, and claims of sustainability.

iso-14040 technical

"framework aligned with ISO-14025, -14040, and -14044, together with"

An international standard that sets out how to measure a product’s or service’s full environmental impact from raw materials to disposal. Think of it as a consistent recipe for telling the complete life story of something — where emissions, resource use and waste occur — so investors can compare claims, spot regulatory or reputation risks, and judge which companies are reducing long‑term environmental costs and potential liabilities.

iso-14044 technical

"framework aligned with ISO-14025, -14040, and -14044, together with"

ISO 14044 is an international standard that sets rules for performing a life cycle assessment, a systematic way to measure the environmental impacts of a product, service, or process from start to finish. For investors, compliance or use of this standard signals that a company is measuring and reporting environmental performance with a consistent, repeatable method—like using the same ruler across projects—making sustainability claims, risks, and improvements easier to compare and trust.

New tool validates SteelPhalt’s commitment to reducing road-laying carbon footprint, providing clear, comparable data for its products to current and potential customers

ROTHERHAM, United Kingdom, May 06, 2026 (GLOBE NEWSWIRE) -- SteelPhalt, a business within Harsco Environmental’s ecoproducts™ line and a leader in sustainable asphalt solutions, today announced the launch of its environmental product declaration (EPD) tool and the verification of the process for generating product-specific declarations under the International EPD System. EPDs are a globally recognized and standardized system, developed under the world’s leading program for environmental declaration. They transparently quantify and communicate the environmental impacts of a product using a life-cycle-based framework aligned with ISO-14025, -14040, and -14044, together with the applicable product category rules.

SteelPhalt produces high-performance asphalt that can help to reduce the carbon footprint of road laying. The EPD report demonstrates the benefits of steel-slag asphalt and the multiple environmentally friendly product types offered, providing evidence of the product’s sustainability credentials.

“SteelPhalt has a long-standing reputation for its innovative use of recycled materials in high-performance asphalt,” said Martin Gray, director of Harsco Environmental’s ecoproducts™ Europe division. “This tool puts that commitment into practice, giving customers the verified data they need to choose the right product for their businesses and report their sustainability impact with confidence.”

SteelPhalt worked with experts in the field to develop the tool to produce SteelPhalt-specific EPDs using a rigorous, multi-step process, assessing key factors such as energy consumption, machinery operations, and material transportation. The EPDs produced by the tool can help customers identify and select products that align with sustainability goals and with any voluntary or government-required reporting.

The EPD production process is certified, meaning SteelPhalt must abide by strict rules and guidelines to produce each EPD and to maintain the approved status. The tool and processes are subject to an annual audit.

SteelPhalt has been a pioneer in recycling and high-performance asphalt production since the 1960s and continues its legacy as a leader in sustainable asphalt solutions.
