Environment Health and Safety Management System (EHSMS) Framework and Policy

Our EHSMS aligns with the latest Environment Management System standard-ISO 14001:2015 and the Occupational Health and Safety Management System standard- ISO 45001:2018. We are actively enhancing our Environment Management System to achieve carbon net-zero. To make our shared goal a reality, our Environment, Health and Safety (EHS) team collaborates globally to meet near and long-term company-wide emission reduction goals in line with the Science Based Targets initiative (SBTi).

The EHS Management System is pivotal to maintaining a safe and healthy workplace for our employees and other stakeholders. It enables us to take a holistic view of our business operations and identify and mitigate potential risks in our operations. It also drives our efforts to continually improve the environment, health and safety standards for employees and stakeholders.

Environment, Health and Safety Management System

Our EHSMS framework is guided by our EHS policy, which establishes environment, health and safety management and sustainability considerations for our major delivery locations. This includes our operations in India, the Philippines, Sri Lanka, South Africa and Romania.

The four key elements of the EHS policy are:

Environment and Sustainability
Encourage Compliance
Employees and Stakeholders (clients, suppliers, contractors and the Government)
EHS Integration and Business Excellence.

GHG Emissions

WNS (Holdings) Limited has approved near and long-term science-based emission reduction targets with the SBTi. The SBTi has verified these net-zero science-based targets of WNS (Holdings) Limited, to be achieved by FY2050:

Overall Net-Zero Target: WNS (Holdings) Limited commits to reaching net-zero greenhouse gas emissions across the value chain by FY2050.
Near-Term Targets: WNS (Holdings) Limited commits to reducing absolute scope 1 and 2 GHG emissions by 42% by FY2030 from a FY2022 base year. WNS (Holdings) Limited also commits to reducing scope 3 GHG emissions by 51.6% per FTE within the same timeframe.
Long-Term Targets: WNS (Holdings) Limited commits to reducing absolute scope 1 and 2 GHG emissions by 90% by FY2050 from a FY2022 base year. WNS (Holdings) Limited also commits to reducing scope 3 GHG emissions by 97% per FTE within the same timeframe.

At WNS, we measure and track our direct (Scope 1), indirect (Scope 2) and in value chain (Scope 3) GHG emissions in context with our GHG (tCO2e) emissions. The methodology used for calculating GHG emissions is aligned with the globally accepted GHG protocol standards developed by the World Resources Institute. Additionally, it helps us identify areas where energy efficiency can be improved and GHG emissions lowered.

We seek to alleviate the negative impact of climate change by identifying related risks and opportunities and actively working toward carbon net-zero alignment with our Environment Management System (EMS). Our EMS focuses on reducing carbon emissions across the entire value chain, including Scope 1, Scope 2 and Scope 3 emissions. We have joined the “Race to Zero” campaign backed by the United Nations and are actively pursuing our SBTi-approved targets, with the primary objective of limiting global temperature rise to 1.5°C.

With streamlined management and the right technology, we are focusing on optimizing our energy consumption. Currently, we utilize green energy based on site dynamics at our existing locations and plan to explore green and energy-efficient buildings for our future offices. Additionally, we have implemented the usage of electric vehicles in locations with charging stations.

Energy Management

WNS is at the forefront of driving change by continually improving energy efficiency and conservation. To attain this objective, we implement several initiatives under our Environment Management System program, including energy consumption monitoring and measurement and taking definitive actions to optimize energy consumption. To target energy efficiency, we adopt energy-efficient and smart equipment and conduct ASHRAE-level audits for our energy-intensive service delivery locations. Our facilities in India have consistently maintained high Energy STAR ratings awarded by the Ministry of Power, underscoring their exemplary performance. WNS is transitioning to conduct operations from LEED, GBCSA, or any equivalent green certified buildings as part of its strategic initiative to orchestrate, positive environmental impact.

As part of our net-zero strategy, we are deeply committed to integrating renewable energy across our operations, thereby reducing dependence on conventional sources. Currently, renewable energy sources, including green energy from the grid and captive solar generation, account for a significant share of our total energy consumption across multiple locations in India and beyond.

Waste Management

Under our EMS program, we are monitoring, measuring and reducing the quantum of waste being generated from our operations. The following are some steps we have taken to reduce waste generation:

Optimal use of IT equipment to reduce e-waste
Digitization in our processes to drive paperless operations
Elimination of use-and-throw items:
1. Reusable ceramic mugs have replaced paper cups
2. Reusable glass water bottles have replaced packaged plastic bottles
3. Reusable acrylic containers with lids have replaced plastic wrap films
4. Use of tissue paper eliminated wherever possible
5. Promote reduction in the use of single-use plastic

All our waste is appropriately disposed of in accordance with the prescribed norms as per specific regions. In order to reduce environmental risk and ensure compliance with regulations, our E-waste, battery waste and hazardous waste are sent to authorized recyclers for processing.

Water Management

The company operates from leased office spaces, where the lessors are primarily responsible for ensuring water availability through multiple sources, including municipal water supply, groundwater extraction and water tankers during periods of scarcity. In certain locations, WNS also procures packaged drinking water for potable use. Most office premises are equipped with centralized sewage treatment plants (CSTPs), owned and managed by the lessors, to ensure proper wastewater treatment.

Amid the growing global water crisis and increasing pressure on freshwater resources, WNS recognizes the importance of responsible water management across its operations. We conserve water and support global sustainability efforts through several measures aimed at minimizing water consumption and preventing leakages, such as:

Push taps installed in place of conventional taps
Waterless, hygienic urinals are being installed
Recycled water is being used wherever possible
Water flow optimization
Awareness mailers and posters on water conservation and the reduction of wastage
