Our journey from carbon reduction to carbon neutrality

In the face of the climate emergency, Atos has committed to reducing the global impact of its operations. From 2012 to 2019, Atos reduced its absolute CO2 emissions by 48%.

In the long-term, Atos intends to reduce carbon intensity by 86% by 2050 versus 2012. This target is fully aligned with the Paris Agreement on climate change, which aims to limit global warming to 2°C. By the end of 2019, we had already achieved a 58% reduction.

Our targets for reducing carbon emissions reflect the progress that Atos is making in minimizing the carbon footprint of its operations. We are doing this mainly through the Atos environmental Program, which focuses on reducing energy consumption, business travel and greenhouse gas emissions. As a signatory to the French Business Climate Pledge, Atos recognizes the need to accelerate innovation and R&D in low-carbon solutions.

In 2019 Atos marked the previous year’s achievement of offsetting 100% of its carbon emissions from datacenters, offices and business travel by shifting its focus towards an even more ambitious program of carbon capture (or sequestration).

Energy-efficient supercomputer test lab opens in Angers

The inauguration of a 2,000 m2 High Performance Computing Test Lab in Angers, France in 2019 reinforced Atos’s leadership in supercomputing while ensuring its commitment to sustainability.

The Test Lab can host the equivalent of 48 BullSequana supercomputers and allows Atos to test supercomputing equipment for its clients under real conditions, supporting both its own and its clients’ work to develop ‘exascale’ supercomputers (capable of processing a billion operations per second).
The site hosts 250 employees involved in developing supercomputers such as the latest hybrid supercomputer from Atos,

the BullSequana XH2000. It operates an energy-efficient cooling system using low- GWP (Global Warming Potential) refrigerant fluid and ‘free-cooling’ that can result in energy savings of 75%. The lab features an energy recovery system that reuses energy generated by the lab to heat or cool Atos offices with an energy efficiency twice that of a standard system. It also incorporates eco- friendly features including a ‘green’ roof and electric vehicle charging, and will be fitted with solar panels in 2020.

Re-using heat to reduce energy consumption

To increase the energy efficiency of our datacenters, Atos continuously invests in technologies and best practices which reduce the power consumption and optimize the energy performance of computing hardware and other electrical installations.

At our strategic datacenter in Fürth in the Bavaria region of Germany, we have installed innovative waste heat reutilization equipment which will help to reduce the facility’s consumption of energy.

Based on the principles of heat exchange, the technology dissipates the heat produced by the operations of the datacenter by transferring heat from the air into a liquid. In a second stage, the hot fluid from the heat exchanger is used to heat the offices. As well as providing heating when needed, by taking out warm air from the facility the system also helps to reduce the power consumption of the air conditioning units in the computer room.

Additional heat exchange technology is due to be installed by mid-2020. When complete, the Fürth system will produce a total of 320kW heating. Excluding the indirect savings in air conditioning, it is estimated that the new equipment will generate total annual savings of 374t CO2.

Mandatory environmental training now in play

As part of its Environmental Management System (EMS), and to raise the awareness of employees, Atos has made its e-learning program covering environmental issues available in five languages and mandatory for all employees.

Atos aims to make its staff more aware of environmental challenges in their roles as employees and citizens. The ‘Atos Green App’ was launched in 2019 to guide employees around the globe to easily follow its corporate social responsibility metrics, announcements and achievements. The app incorporates a gamified design for increased user engagement.

The mandatory e-learning and app are part of the wider strategy of Atos to ensure that all its employees practice eco-friendly behavior in line with its ambition to achieve ISO 14001 certification at each of its main eligible sites. 100% of Atos employees are now covered by Atos EMS and over 76% work at sites with ISO 14001 certification (50% in 2018).

Atos powers towards ISO 14001 certification target

In November, Atos|Syntel achieved ISO 14001 certification for all four of its major Indian sites at Mumbai- Seepz, Mumbai-Airoli, Chennai and Pune (accounting for 25,585 employees) less than one year after the acquisition of Syntel and its incorporation into Atos’s environmental program. “We are leading by example and setting a new standard in India,” Rakesh Khanna, CEO at Atos|Syntel said.

Atos aims to certify all its main facilities around the world for ISO 14001. The certification requires high standards in a range of environmental issues such as carbon emissions, energy consumption, waste management, recycling, water use and employee awareness and is increasingly requested by prospective clients. All Atos core datacenters and offices (with more than 500 employees) are required to undergo certification. The ongoing target is for 80% of eligible sites to be either certified or in the process of certification. At the end of 2019, around 89% of all targeted sites were already certified or had entered the certification process (85% in 2018, 80% in 2017).
