  • International ranking distinguishes NOS, especially in the Environmental area
  • Companies with the best scores enter the Euronext VigeoEiris family indices
  • By 2030, NOS aims to lower operational energy consumption by 85% per unit of data traffic (MBs) and its greenhouse gas emissions by 75%, and increase its consumption of green energy by 80%

NOS is the 5th highest ranked company in Europe in the VigeoEiris ESG Rating –a highly credible and recognized international ranking in the financial market, developed by VigeoEiris, an affiliate of Moody´s. NOS was ranked in the “Advanced” level, winning 60 out of a 100 points, in a survey that evaluated 41 telecommunications companies.

The VigeoEiris ESG Rating evaluates the ability of companies to build sustainability factors into their strategies and management practices with the goal of promoting economic growth, responsible investment and value creation in the medium to long term. Companies with the highest number of points in this rating are selected to be part of the Euronext VigeoEiris family indices.

The survey looks at six different areas: Company Behavior, Human Rights, the Environment, Involvement with the Community and Human Resources. The points awarded to NOS increased by 50% compared to the previous evaluation done in 2018, mainly in the Environmental area, reflecting a number of best practices and initiatives implemented across the company in all areas over the last few years.

1. Objectives and goals to reduce energy consumption and emissions

In 2019, NOS signed up to the Letter of Commitment “Business Ambition for 1.5ºC”, an initiative of the United Nations Secretary General, making it one of the first companies in Portugal to join this worldwide movement.

Based on likely medium term business trends, the following consumption and emission levels were projected and targets defined through until 2030:
  • Reduce the consumption of energy for its operations by 85% per unit of data traffic (MBs), compared to 2015
  • Reduce the carbon footprint (scope 1 and 2 emissions) of its own operations by 75% compared to 2015
  • Consume 80% of its electricity from renewable energy sources.
The targets defined are in line with the social and scientific consensus concerning the contribution necessary from the private sector for the transition to a low carbon world.

2. Implementation of energy efficiency measures

Between 2015 and 2019, NOS reduced its energy consumption per unit of data by 62%. This result is a reflection of the investment the company has been making:
  • In the access network, through its comprehensive modernization, increase in capacity and installation of more efficient equipment, resulting in savings in energy of around 25%, for the same volume;
  • In its administrative buildings and its own store network, through modernizing and optimizing the working of its air conditioning systems and LED lighting installation, which puts NOS on track to comply with the goals set for 2020: 9% less energy consumption in buildings and 35% less energy consumption in its own stores, compared to 2015 figures;
  • In the car fleet, with the progressive transition of the entire fleet to electric vehicles and the introduction of more electric charging stations in NOS’ different premises;
  • In its internal culture, through measures to encourage the reduction in the environmental footprint of employees, including offering special conditions for acquiring electric bicycles and cars, providing free parking for bicycles in all buildings; and by fostering the “Lifts” program, which encourages employees to share their cars for journeys to and from the office, and for business travel between cities.

3. Waste Management and the Circular Economy

Also, as part of the management of the life cycle of its products and services, NOS has implemented measures to make its operations more eco-efficient, such as:
  • Collection of and putting back onto the market used equipment from its fixed service (TV boxes and routers), avoiding additional consumption of raw materials and energy, and increasing the level of resource circularity of the company’s processes. The percentage collection of these kinds of equipment is currently around 83%, an increase of 13 percentage points between 2015 and 2019.
  • Implementation of selective collection systems which have ensured that since 2015 more than 95% of waste produced in its operations are sent for multi-material recycling or energy recovery.
  • Implementation of actions to increase awareness among employees and partners about the environmental impact of plastic waste and individual best practices to reduce the amount produced. In 2019, NOS eliminated plastic cups from machines providing water on its premises and reduced plastic packaging and other plastic waste by 8%.
  • Establishing protocols with third sector organizations to donate used equipment and materials, such as desktop computers, monitors and accessories, increasing the useful life of these resources and supporting the activity of partner institutions.

4. Environmental Management System

NOS has an environmental management system certified in accordance with the ISO 14001:2015 standard and which covers around 90% of its employees. The environmental management system – as well as quality (ISO 9000:2015 certification), health and safety at work management systems (ISO 45001:2018) – is evaluated systematically, ensuring that defined goals and targets are monitored, and performance continually improved.
