Greenhouse Gas Emissions

EM-CM-110a.2
Discussion of long- and short-term strategy or plan to manage Scope 1 emissions, emissions reduction targets, and an analysis of performance against those targets
Scope 1 emissions represent a significant portion of emissions resulting directly from our operations.
Our current and future decarbonization efforts are supported by the improved accuracy of our GHG inventory, company-wide data management, and strategic alignment with our business goals.
With more detailed emissions data, we are developing and implementing Scope 1 reduction strategies specific to each line of business. For example, the sourcing of renewable diesel is a significant Scope 1 reduction opportunity among our Aggregates and Concrete segments, while sourcing renewable natural gas and promoting production efficiencies are more impactful for the Asphalt segment.
GHG Emissions & Climate
EM-CM-120a.1
Air emissions of the following pollutants:
(1) NOx (excluding N2O), (2) SOx, (3) particulate matter (PM10), (4) dioxins/furans,
(5) volatile organic compounds (VOCs), (6) polycyclic aromatic hydrocarbons (PAHs), and (7) heavy metals
Air quality is an important issue in our operations and is managed using industry practices. We maintain compliance with regional air quality permits but are not currently able to track air emissions beyond GHG emissions at an enterprise level.

(1) Total water withdrawn (m3)
Vulcan sites source water from multiple sources such as groundwater, surface water, captured stormwater, and municipalities.
Volumetric tracking of all water sources is not operationally feasible and unavailable for disclosure at a company level. However, we are able to disclose water sourced from municipalities through our utility management system.
In 2024, we recorded approximately 720 million gallons (2,726,030 m3) withdrawn from municipal sources.
Water & Wastewater Management
(2) Total water consumed (m3)
The only significant use of water in Vulcan's operations is rinsing rock and spraying on roads and trucks to abate dust. Water is not an integral input to the final aggregates products.
Water consumption is not tracked company wide. However, select sites calculate consumptive water use through water balances that are then reported to regional agencies to maintain permit compliance.
Our Austin Quarry in Madera County, CA is an example of a Vulcan site required to report regularly
water withdrawal and calculated consumptive use.

Percentage of each in regions with High or
Extremely High Baseline Water Stress (%)
Approximately 66% of Vulcan's water volume withdrawn from municipal sources came from watersheds designated by the WRI Aqueduct Water Risk Atlas as Extremely High or High water stress.
Municipal sources are only a portion of Vulcan's total water use, but it is the only withdrawal source that is currently tracked at a company level. The disproportionately high volume of municipal water sourced from stressed regions is likely due to stricter withdrawal regulations in those regions, requiring Vulcan to source from regulated utilities.
Water & Wastewater Management
Waste Management
EM-CM-150a.1
Amount of waste generated (t),
Our quarry operations differ from mining for metals or other construction materials in that they do not result in contaminated or hazardous tailings or wastewater. The aggregates and by-products from our quarries are largely considered inert, and reused/recycled products are included in our sustainable products portfolio.
In recent years, we have consolidated our waste management into a single service provider, making it easier to track data. Reported waste in our operations includes (1) universal and (2) vehicle and equipment maintenance waste.
Amount of waste generated: In 2024, we generated 24 tons of Universal Waste and 3,424 tons of Vehicle/Equipment waste.
Percentage hazardous and
Hazardous waste designations and disposal regulations vary by state. We adhere to disposal requirements applicable in all states where we operate. Certain waste materials generated by Vulcan's operations that are designated as "hazardous" at a federal level are present in relatively small amounts in both the Universal Waste and Vehicle/Equipment Maintenance waste streams; however, the exact amounts are not currently quantified.
Performance Index
Percentage recycled
We work with our waste management service provider to recycle and divert waste from landfills, the two categories of waste we track:
Universal waste: 100% diverted (24 tons)
Vehicle/Equipment Waste: 96% diverted (3,287 tons)

Description of environmental management policies and practices for active sites
From permitting to development to end-of-life reclamation, we are dedicated to protecting natural resources of approximately 310,000 acres through responsible development.
We collaborate with local and federal agencies to protect endangered species identified within our operations and develop community-based ecosystem management plans that offer longterm conservation benefits. At the end of 2024, a pilot project was created to standardize Vulcan's approach to measuring and reporting ecosystem and biodiversity metrics. This pilot program is expected to fully launch in 2025 with updates in reporting throughout the year.
Environmental management is employed at a site level and uses a combination of strategies
including, but not limited to:
Internal assessment and analysis
Environmental Impact Assessments (EIA)
Buffer zones
Conservation and mitigation banks
Partnership with the Wildlife Habitat Council (WHC)
Land Use & Ecological Impacts
Terrestrial acreage disturbed (ac), percentage of impacted area restored
We do not currently quantify and report this data at a company level.
An example of restored mining land is our Azusa Rock Quarry in southern California. The program included reclaiming the severe, steep slopes and previously reclaimed large benches of the 100-plus-year-old quarry. The large benches, referred to locally as the "Mayan Steps, were
completely transformed into micro-benches approximately 2 feet deep by 2 feet high. The micro-
benches were seeded and planted with native plant species characteristic of the local habitat.
Wildlife Habitat Council recognized Vulcan as exceeding regulatory requirements with its efforts to restore the coastal sage scrub and chaparral vegetation communities on such difficult terrain,
which is a significant ecological contribution to increasing the number of acres and quality of native
habitats available for wildlife species that inhabit the mine site.

Number of reported cases of silicosis
Crystalline silica is a naturally occurring mineral that can form fine particles during mining, rock crushing, and production of ready-mixed concrete. Prolonged exposure and inhalation of crystalline silica can cause significant health issues commonly associated with our industry.
We employ industry best practices to manage fugitive dust emissions and reduce exposure to crystalline silica, in addition to other particulate matter. We also conduct health screenings for employees to monitor for potential health conditions such as silicosis.
Zero cases of silicosis were reported company wide in 2024. Health & Safety
Percentage of products that qualify for credits in sustainable building design and construction certifications
We support our customers in the development of certified low-carbon infrastructure and sustainable building design. We collaborate with customers to design product mixes using alternative and low-carbon materials.
We quantify and categorize these products through EPDs, GWP budgets, and tons of injected CO2 through CarbonCure. However, we do not currently report the total revenue associated with these products.
