Protecting Resources, Preserving our Environment

As an agriculture-based company, Constellation Brands relies on water, land and other resources for our continued growth and success. In order to safeguard natural resources, we are committed to serving as good stewards of the environment by ensuring that our facilities operate sustainably and by putting measures in place to help minimize our use of precious natural resources. Beyond our operations, this focus on sustainability is also critical to the people, communities and environments where we operate.

While we strive to elevate sustainable practices in every corner of our operations, three of our most passionate priorities are optimizing our water stewardship, limiting greenhouse gas (GHG) emissions and reducing waste.


We recognize the human right to water and sanitation, and given the nature of our business, water is an essential resource Water conservation and stewardship is a foundational pillar of our sustainability strategy. To maximize our beneficial impacts on the industry and the communities in which we operate, we partner locally, joining forces with businesses and building community relationships. That helps us to collectively increase site water efficiency, maintain source availability and quality, advance conservation efforts and report transparently.

We strive to boost water efficiency through continuous improvement. Our breweries in Mexico continue to invest in technology that drives the efficient use and recycling of water. In our Obregon brewery, for example, we updated equipment in the Water Recovery Plant, installed two new reverse osmosis units for the treatment of well water, and made other changes to lower water consumption and increase operational efficiency. These investments drove a reduction in the ratio of water consumption per hectoliter of beer produced from fiscal 2017 through fiscal 2020 in both our Obregon brewery (18% reduction) and the Nava brewery (13% reduction). The Obregon brewery’s wastewater treatment plant treats 100% of water from industrial and sanitary drainage, avoiding pollution to the soil and aquifer while supporting our commitment to comply with local water legislation.

Our winery and vineyard operation teams also have implemented new processes to optimize water use. In Napa Valley, our vineyards use new technologies to maximize water conservation and to ensure that vines only receive what they need, when they need it. This includes minimizing overwatering, excess run off, erosion, and unnecessary depletion of source supply, which we measure with soil monitoring devices and weather stations. These ongoing improvements in water management over time have led to the realization of significant water reductions across the Napa Valley vineyard complex. Compared to fiscal 2018, the collective Napa Valley vineyards used 51% less water than three years ago – representing more than 100 million gallons of water conserved.

Additionally, we support goals set by well-established entities such as the United Nations to guide our sustainability efforts and ensure we are keeping up with the latest priorities. Our water conservation and stewardship supports several United Nations Sustainable Development Goals:

  • We support United Nations Sustainable Development Goal 6 by focusing on longer-term targets, including reducing pollution to improve water quality, increasing efficient use of water and ensuring sustainable withdrawals and supply of freshwater to address water scarcity, and supporting and strengthening the participation of local communities in improving water and sanitation management.
  • We support United Nations Sustainable Development Goal 12 by promoting sustainable management and efficient use of natural resources.
  • We support United Nations Sustainable Development Goal 14 by preventing and significantly reducing marine pollution through our Pacifico Preserves and Corona’s Protect Our Beaches initiatives.
  • We support United Nations Sustainable Development Goal 15 through our Lodi Rules certification and our Fish Friendly Farming certification by restoring fish and wildlife habitat and improving water quality in Napa and Sonoma counties in California.


As part of our commitment to protect the environment and the communities where we operate, we are decreasing our dependence on non-renewable energy sources whenever possible and reducing greenhouse gas emissions and energy consumption. We continuously monitor our carbon footprint and have worked to effectively reduce emissions per liter of product produced. To help us track progress and understand continued opportunities, we track four major Greenhouse Gases (GHGs): carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and hydrofluorocarbons (HFCs) in accordance with the international guidelines of the Greenhouse Gas Protocol developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD). We express our carbon footprint in terms of carbon dioxide equivalents (CO2e)

Our vineyards actively work to reduce their footprint every day. Our Ruffino Group in Italy installed solar panel systems in the Tuscan estates of Gretole and La Solatia, with the potential to supply 75% of the electric energy in La Solatia estates. The Pontassieve winery also received certification from A2A Energia for its use of renewable energy sources.

As part of our ongoing efforts to reduce GHGs and to comply with changing environmental standards, our Gonzales Winery invested in a refrigeration system that is more energy efficient and does not deplete the ozone layer. This is achieved in large part by using ammonia refrigerant, which requires less electricity and is safer for the environment than the previously used R-22 refrigerant. To do our part in reducing our Carbon Footprint, we support three United Nations Sustainable Development Goals:

  • We support United Nations Sustainable Development Goal 2 by partnering with key raw material suppliers to develop and implement sustainable farming/agriculture initiatives to reduce GHG emissions.
  • We support United Nations Sustainable Development Goal 7 by decreasing our dependence on non-renewable energy sources whenever possible, reducing greenhouse gas emissions and energy consumption.
  • We support United Nations Sustainable Development Goal 12 by promoting sustainable management and efficient use of natural resources.


Waste is a part of any production process, and we are continually improving the ways we manage our waste to reduce the environmental impact of our waste generation, transportation and disposition. At our sites across the globe, our actions often involve composting, recycling, and diverting materials.

Our Nava and Obregon breweries in Mexico each diverted 99% of the waste produced in fiscal 2020 and our Ruffino Group applies the principle of continuous improvement to their waste management by reviewing their contracts with waste management companies annually. This exercise helps uncover further recycling opportunities and identify new ways to engage with dry goods suppliers (glass, corks, labels and cardboard) on waste reduction initiatives.

In the last two years, over 640,000 tons of by-products generated during production at Nava have been used by others in the region as feed for cattle, sheep, and pigs. The brewery also used alcohol residue generated during production of seltzers to make disinfectant gel that helps keep more than 4,000 employees in Mexico safe during the pandemic.


Constellation Brands is committed to providing a safe and healthy working environment and developing a culture where every employee takes responsibility for their own safety as well as the safety of others while minimizing our impact on the environment in the communities where we live, work and source. Our management team and employees work together with a sense of shared responsibility to ensure that we operate our business in compliance with all applicable regulatory requirements in each market where we operate around the world.

As an agriculture-based company, environmental issues are not only important to us – they are an essential component to our continued growth and success. Because we rely on the land for our livelihood, it is critical that Constellation does all it can to ensure clean water, air and soil at all of our sites and in all of the countries and communities where we operate. Our aim is to look for ways to improve the environment, while also minimizing Constellation’s collective environmental impact.


We understand that much of what we do to advance sustainability can be amplified through our conservation and sustainability certifications and our participation in industry programs, which share a wide range of best practices and help us measure progress.
