We believe responsible, sustainable operations benefit our communities and drive positive results for the long term. As an industry leader, Vulcan’s aim has always been to meet—and strive to exceed—all federal, state and local environmental regulations. Once again, in 2020 we maintained a citation-free environmental inspection rate of over 98%.

However, environmental sustainability means looking beyond what is required of a company by governments and regulators. We continue to make progress on reducing our carbon footprint, increasing our energy efficiency, measuring water use, reducing waste and managing our land with biodiversity in mind. It’s the right thing to do for society, for our business and our stakeholders.

 

2020 Highlights

We decreased Scope 1 and Scope 2 greenhouse gas emissions by 3.3% from 2019 and significantly improved our carbon management score as measured by the Carbon Disclosure Project. At the end of 2020, approximately 40% of our off-road fleet was equipped with Tier IV engine technology or Tier IV interim technology. We also continued to make progress with our water and waste management and recycling programs

We partnered with environmental and other non-governmental organizations on a variety of conservation initiatives in our states across the U.S. and in Mexico. We are proud to maintain the fourth largest number of Certified Wildlife Habitat sites of any industrial company in the U.S., in partnership with the international Wildlife Habitat Council (WHC).

Managing land sustainably for the long term.

Minimizing impacts to the land, the water, the air and improving biodiversity is vitally important to Vulcan. We take a holistic approach to land management because mining is only an interim use of the land. The presence on a site of wetlands, waters, endangered species, cultural resources, and proximity to property boundaries and neighbors are all factors that are considered during site development. Making thoughtful decisions during site development helps to minimize these potential impacts. Our environmental specialists, land managers, geologists, engineers, hydrologists and external affairs personnel work together with key outside parties to incorporate state-of-the-art environmental controls while mining infrastructure materials. Future uses of the property following mining are considered during site development and operation. The planned future use of the property will affect the reclamation process and can dictate specific requirements beyond what is required by state mining reclamation regulations.

In 2020, we continued essential partnerships with environmental organizations and non-governmental organizations (NGOs) in the U.S. and Mexico that strengthen our position as a sustainable business. Examples include our 30-year partnership with the Cahaba River Society, which works to restore and protect the longest free-flowing river in Alabama and is the primary drinking water source for one-fifth of the state’s population.

Vulcan also maintained our Cajon Creek and Colton Dunes Conservation Banks in California, which we set up to provide permanent protection of natural areas and habitats. We are also currently working with the Sierra Foothill Conservancy to establish the Fenston Mitigation Bank in Madera County, California, which will provide thousands of acres of mitigation for impacts to the habitats of several endangered species in the San Joaquin Valley. Our Sac-Tun operation near Playa del Carmen, Mexico is implementing a long-term environmental vision and strategy that has been praised by local government authorities and NGOs as a model for other businesses and industries in Mexico.

The variable frequency drive (VFD) pumps in this feed prep system at the Diamond Sand Plant reduce energy consumption and equipment wear while improving the overall operational efficiency of the plant.

Managing energy and reducing greenhouse gas emissions.

Our individual operations are well below the U.S. Environmental Protection Agency threshold for reporting and permitting of greenhouse gas (GHG) emissions. However, since 2018, Vulcan has chosen to report GHG emissions to the Carbon Disclosure Project (CDP). We are continuing to improve operational efficiencies at our sites, which has resulted in less GHG emitted per ton of production and shipments by lowering fuel consumption and energy needs. The major GHG reduction achieved from 2013 to 2014 was the result of the divestiture of the company’s cement production facility. Since Vulcan exited the cement business, our baseline for measuring GHG emissions is 2015 in order to provide a more accurate picture of our progress over time.

Approximately 40% of our off-road fleet vehicles have now been transitioned into Tier IV and Tier IV interim engine technologies. In 2020 decreased Scope 1 and Scope 2 greenhouse gas emissions by 3.3% from 2019.

Our 2020 GHG emissions snapshot

  • Total U.S. GHG emissions for 2020 were 965,246 metric tons of combined Scope 1 and Scope 2 emissions, or 113.3% of our 2015 baseline emissions of 852,118 metric tons.  
  • However, Total Scope 1 and Scope 2 GHG emission increases in recent years have been at a rate lower than the rate of production and revenue increase.
      • 2020 Total Scope 1-2 Emissions Revenue Factor (MTCO2e per $MM Revenue): 79.8% of the 2015 baseline
      • 2020 Total Scope 1-2 Emissions Shipment Factor (MTCO2e per Tons Shipped): 97.3% of the 2015 baseline

Vulcan’s goal in 2021 is to set specific GHG reduction targets for the company. We are actively assessing the scope and scale of potential opportunities to do our part to reduce future GHG emissions. At a minimum, future GHG reductions will come by means of continuing heavy equipment replacement with higher efficiency models, procuring energy from renewable sources and seeking production efficiencies. We are confident that there are many more opportunities to reduce the carbon footprint of our quarrying operations, distribution and transport networks, and the projects in which our products are used.

Additional information regarding our carbon footprint is available in the Data Dashboard and in our 2020 CDP Climate Change Questionnaire.

Dust control systems on our aggregates processing equipment reduce PM10 emissions by 94%. Common controls include spraying water through high pressure, low-flow nozzles that properly wet the material without flooding the equipment.

Running our operations to protect the air: non-GHG emissions management.

We are committed to reducing the emissions of air pollutants released from our operations. The primary air pollutant from the aggregate operations is particulate matter. The company vehicle fleet and the hot-mix asphalt (HMA) plants all release products of combustion (CO, NOx, SOx, particulates) from the use of petroleum-based fuels. A rough estimate of the total emissions from the company’s operations and mobile equipment was prepared and the total amount of primary criteria pollutant emissions was estimated in the range of 20,000 to 25,000 tons per year. Work is underway to improve the accuracy and detail of these estimates and to establish a baseline year to enable measurement of progress reducing the company’s air pollutant emissions.

The majority of the company’s operations are classified as minor or synthetic minor sources of air emissions and operate under the authority of federally authorized state or local permitting programs. We are proud of our compliance record and efforts to ensure adherence to all permit conditions and requirements.

Preserving and protecting our water resources.

We are committed to the protection and preservation of water resources including surface water, groundwater, and wetlands. Aggregate sites have water treatment systems consisting of settling ponds or mechanical filtration equipment such as clarifiers and filter presses, all for the treatment of water from the processing operation. Water used in the processing operation is treated to reduce total suspended solids (TSS) levels so the water can be recycled, or in cases where excess water is present, the treated water is discharged.  

Aggregate mining and processing operations collect stormwater that falls within the facility boundaries and store it in pond systems or mined-out quarry pits. The water is used in place of pumped groundwater. This combination of recycling treated water and collected stormwater runoff reduces the need for extracted groundwater to supply the operation. An estimated 70% of the company’s aggregate mining operations recycle water.

Our primary objective is to eliminate or reduce the amount of waste material generated in the first place. Where waste generation is unavoidable, we strive to recycle as much as possible including tires, motor oils, batteries, conveyor belts and other consumables to reduce landfill waste.

Reducing waste generation and increasing recycling.

Ensuring proper management of waste materials to prevent the release of contaminants to the environment is good environmental stewardship and good risk management. Our source reduction and recycling initiatives minimize the possibility of environmental damage to soil, surface or groundwater. We also proactively guard against regulatory violations and potential liability for cleanup actions under the Resource Conservation and Recovery Act (RCRA), the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), state environmental laws and regulations, and private party remedial response actions. The company has engaged in a focused effort to maximize the amount of potential waste material that is recycled.
