“This Sustainability Commitment includes our updates for Fiscal Year 2020. Despite the challenges due to the COVID-19 pandemic, we have made progress on many of our sustainability commitments and goals. We would like to thank our employees, suppliers, members and the communities where we operate for their continuing support to help us navigate the challenges of the COVID-19 pandemic.”

OVERIVEW

Our aim is that our business remains responsible, resilient and relevant in accordance with our Mission Statement and Code of Ethics.
Code of Ethics
  • Obey the law
  • Take care of our members
  • Take care of our employees
  • Respect our suppliers
  • Reward our shareholders
Mission Statement
To continually provide our members with quality goods and services at the lowest possible prices.

These inform and guide our everyday goal to do the right thing and are the foundation of our business. Costco will continue to adapt as we learn more about our impact and global challenges such as climate change, human rights issues, and compromised natural resources.


Sustainability to us is remaining a profitable business while doing the right thing. We have adopted the following principles and responsibilities to help us navigate the dynamic and changing future while still striving to do the right thing and remain a low-cost and efficient business operator.
Our Sustainability Principles
  • For Costco to thrive, the world needs to thrive. We are committed to doing our part to help.
  • We focus on issues related to our business and where we can contribute to real, results-driven positive impact.
  • We do not have all of the answers, are learning as we go and seek continuous improvement.
Our Sustainability Responsibilities
  • Take care of our employees.
  • Support the communities where our employees and members live and work.
  • Operate efficiently and in an environmentally responsible manner.
  • Strategically source our merchandise in a sustainable manner.

SUSTAINABILITY GOVERNANCE & EDUCATION

Sustainability is important to all levels of our company and we are working together to meet our goals and make progress on our initiatives. Examples include:
  • Biannual reporting to our Board of Directors
  • Monthly reporting to our global executive team
  • Our Vice President of Global Sustainability and Compliance reports directly to our CEO and chairs our newly formed Environmental Social Governance (ESG) Executive Advisory Committee, which is made up of cross-functional leadership to help manage the integration of our sustainability policies into our current business structure
  • We also keep our members and employees informed of our efforts through articles in the monthly publication, Costco Connection, and additional articles for our employees in Costco Today
  • We conduct various training and educational opportunities for our employees and suppliers throughout the year, many of which are discussed throughout this Sustainability Commitment
  • We provide policies and guidelines to our employees and suppliers as well as additional job aids and standard operational procedures to help our employees understand how to remain in compliance with ou policies and programs

SUSTAINABLE DEVELOPMENT GOALS (SDGs)

Employees

In FY2021 and in accordance with Point No. 1 of our 10-point Climate Action Plan, we assessed the materiality of the United Nations Sustainable Development Goals (SDGs) to create a framework for prioritizing our Climate Action Plan in relation to our business model. The SDGs are a set of 17 globally accepted 2030 goals with 169 targets that balance economic, social and environmental dimensions of sustainable development.

Following standards set by the UN Global Compact for SDG Disclosure, we conducted a materiality assessment with assistance from an outside third party to narrow down and prioritize what makes sense for our business. The assessment included:

  • Undertaking preliminary scenario planning exercises
  • Performing risk and opportunity assessments of operations and merchandising
  • Incorporating our Code of Ethics and what “doing the right thing” means to us
  • Emphasizing the importance of mapping and tracing our value chains, to learn what is actually happening on the ground and to help us help make actual positive change
  • Integrating our Forest Conservation Commitment and Verisk Maplecroft materiality assessment of our key commodities
  • Benchmarking against peers for industry alignment – we are comprehensive relative to our peers

As a result of this assessment, we have initially identified the following 7 UN SDGs as our priorities:

  • Clean Water and Sanitation (6)
  • Decent Work and Economic Growth (8)
  • Reduced Inequalities (10)
  • Responsible Consumption and Protection (12)
  • Climate Action (13)
  • Life Below Water (14) and
  • Life on Land (15)

The below chart outlines these goals, our initial key performance indicators, our FY2021 baselines and where you can learn more about each SDG throughout this Sustainability Commitment.

SUSTAINABILITY ACCOUNTING STANDARDS BOARD (SASB)

In FY2021, and in accordance with Point No. 10 of our 10-Point Climate Action Plan, we began an assessment of our ESG global reporting requirements, which included the identification of Sustainability Accounting Standards Board (SASB) topics that are material to our business. SASB develops and maintains sustainability accounting standards for 77 industries in 11 sectors, with corresponding reporting metrics to provide investors information pertaining to topics that might have a material financial impact on our company.

We identified two SASB industries most relevant to our business: Food Retailers & Distributors and Multiline; and Specialty Retailers & Distributors. With the assistance of third-party ESG Reporting consultants, we conducted a data quality risk-assessment and created information governance frameworks and procedures for select key metrics. We have identified a subset of SASB metrics for 2021 reporting. The following SASB reference table serves as a guide to our initial disclosure for this first year. We intend to expand our SASB disclosures in the coming years.

DATA SECURITY

Costco identifies and addresses data security risks based on several frameworks, including ISO27001, the NIST Cyber Security Framework (CSF), and the Payment Card Industry Data Security Standard (PCI DSS). The company’s governance policies, including the Information Security Policy, outline high level strategic information security objectives to meet compliance and regulatory requirements, and we have standards, procedures and programs to provide guidance on the management of data security risks.

Costco has implemented several technology measures, leveraging third party security providers when needed, and engages in multiple activities to identify and mitigate vulnerabilities and risks in systems (e.g., scanning for common vulnerabilities and exposures, penetration tests on internal and external networks, code scans on applications, employee awareness and training, internal and external audits). Costco also assesses the risk that third parties with whom we do business presents to Costco in an effort to reduce the likelihood of security incidents or business interruptions to our business.

Costco employs a “defense in depth” strategy to address the attack chain and safeguard our systems and information. Some of the measures utilized by Costco include phishing detection and mitigation, multi-factor authentication, information system protection systems such as anti-malware, anti-ransomware, endpoint detection and response, file integrity monitoring, and other system hardening techniques. Networks are protected using network detection and response capabilities, are segmented, and provide flow level visibility into lateral movement potential; e-commerce systems are protected by a web application firewall. This layered defense concept combined with our detection and response capabilities allow us to minimize the potential risk of unauthorized access to our systems and information.

PROGRESS

In this document, we explain how we continue to incorporate sustainable practices in our business and provide examples to help illustrate our progress. Our practices may change over time, as we learn more and adapt to our ever-changing world, and we update our Commitment to reflect these changes.
