• PricewaterhouseCoopers LLP provided limited assurance of management’s assertion related to our 2014 total Scope 1 and Scope 2 greenhouse gas emissions data.
  • Our Brazilian operations received gold certification from the Brazil Greenhouse Gas Protocol Program.


Committed to Truth in Reporting


We obtained third-party assurance for some of the more critical data elements contained in our 2014 sustainability reporting.


PricewaterhouseCoopers LLP (PwC) again provided limited assurance on our total Scope 1 and Scope 2 greenhouse gas emissions data under the American Institute of Certified Public Accountants’ attestation standards. (View PwC’s limited assurance report.) 


We continued to improve our existing sustainability metrics systems during 2014 to provide clearer and more consistent definitions to be used in every region and location around the world.


We also continued implementing our enhanced data capture and reporting strategy by linking operational systems to a global data collection and reporting system. In addition, our Global Primary Products business group developed and implemented a new greenhouse gas data management system, which also more effectively captures water and waste metrics.


In 2014, our Brazilian operations again received gold certification from the Brazil Greenhouse Gas Protocol Program for transparency in reporting and quantifying its emissions inventories. The certification was granted following an assessment by independent Brazilian auditor Vanzolini Foundation. Alcoa was one of the first companies in Brazil to participate in the program.


Internal & External Processes

In addition to our comprehensive internal metrics systems, we employ a variety of processes to bring assurance that our operations are transparent and the information we report is accurate and truly reflective of our actual results. Examples include the following:

  • Internal Audit: We have a rigorous internal audit process that evaluates our locations on five areas: environmental; health & safety; operational excellence; financial & business processes; and information technology. Additional information can be found on our Internal Audit web page.
  • U.S. Securities and Exchange Commission (SEC) Filings: We file or furnish significant information, including our annual, quarterly, and current reports, proxy statement, and sustainability highlights reports with the U.S. SEC, and we are subject to its rules and regulations.
  • Community Advisory Panels: Under the Alcoa Community Framework, each of our locations is encouraged to convene a community advisory panel to provide a forum for ongoing interaction between the plants and area residents. We provide extensive information regarding the issues raised by these community advisory panels, as well as the actions we have taken to address them, in the Stakeholder Engagement section.
  • Annual Employee Survey: Our Global Voices employee survey, translated into multiple languages, helps us identify best practices for increasing employee engagement.
  • Health and Safety Committees: Each location has various task, department, ad hoc, and other committees to develop and implement health and safety programs based on the location’s strategic health and safety plan. These leadership groups include a cross-section of personnel from the facility.
  • Business Conduct and Conflict of Interest Survey: We deploy a survey to selected employees each year asking them to certify their compliance with our business conduct, anti-corruption, and insider trading policies.
  • Integrity Line: Our Integrity Line allows employees and any other concerned parties around the world to confidentially report any concerns they may have regarding potential violations of our policies and practices, including those affecting data.
  • Environmental and Social Impact Assessments: Prior to constructing new facilities or expanding existing ones, we conduct and publish an environmental and social impact assessment to determine what effects the project would have on the community.
  • External Partnerships: We partner with many external organizations on a project or ongoing basis to address operational and community issues. Examples can be found in the Stakeholder Engagement section.


External Standards

We rely primarily on our Values supported by internal policies and standards to guide our behavior.


We believe it is the role of governments, not companies, to sign on to international laws and conventions, such as the U.N. Universal Declaration of Human Rights and the International Labor Organization conventions. However, we are fully aligned with these international conventions, and we use them to guide our internal policies and standards.


Where any international convention is required by the government of a country in which an Alcoa facility is located, our facility will abide by that convention since our locations must follow the laws of the country in which they are located. When an internal requirement exceeds that of the government, which is often the case, our location must abide by this more stringent standard. 


A key challenge in our growth strategy is to understand and accommodate the different customs and values that we encounter during our work in various countries. In these situations, we understand that we must engage with these stakeholders to resolve any discrepancies without compromising our own values. We don’t have a perfect answer, but we believe that, as a first and continuing step forward, dialogue will help parties understand one another’s viewpoints.


As an industry leader, we feel it is important to help develop guidelines and standards that will move the industry closer to sustainability. We continue to actively participate in the development and achievement of the International Aluminium Institute’s Aluminium for Future Generations Sustainable Development Programme. This program comprises 13 voluntary objectives and 22 performance indicators that are designed to encourage continual improvement in the industry’s sustainability performance. 


We are a participant in the United Nations Global Compact, the world’s largest corporate responsibility initiative. As a participant, we pledge to advance several goals related to the environment, human rights, labor standards, and anti-corruption, as well as report on our progress. View our most current

External Principles and Initiatives

We subscribe to or endorse the following externally developed principles or initiatives:


Sustainability Certifications

Many of our locations are certified to the International Organization for Standardization’s ISO 14001 (environmental management systems) standard when the certification provides business value. 


All of our locations and business units can seek ISO certification under the global certificate, increasing overall efficiency in obtaining this certification. Locations that select other registrars can continue their location-specific registration if they choose. Where synergies and business value exist, business unit and location environmental management systems are to be certified through our global certificate.


At the end of 2014, 65 of our locations throughout the world were certified to ISO 14001. We also had 13 locations certified to the Occupational Health and Safety Management System specification (OHSAS 18001).
