Our GHG mitigation strategy consists of two key elements.
- Energy Efficiency
- Renewable Energy both (a) strategic procurement and (b) onsite generation
Of these, strategic RE procurement will contribute the maximum to GHG emission reductions.
The visual below depicts a graphic representation of this strategy.
Over the preceding five year period, we have implemented a variety of energy efficiency measures.
- Green Buildings: We were one of the early adopters of Green Building Design with 18 of our current buildings certified to the international LEED standard (Silver, Gold, and Platinum).
- Server virtualization: Since 2007, we have been working on a server rationalization and virtualization program, through which we have decommissioned old physical servers and replaced the processing capacity with virtualization technology on fewer numbers of servers. As of March 2017, we have 2,920 virtual servers (2,088 in 2015-16) running on 312 physical servers which contributes to an energy savings of approximately 12.5 million units annually. The savings showed an increase of 35% over the previous year. This is based on sever rating of 0.75 KW operating for 24 hours and 5 days in a week. This, we believe, is a conservative estimate considering that many servers run for 7 days a week and the power rating ranges from 0.75 Kw to 1 Kw (we have considered the lower power rating for the savings estimate calculation).
- Operational Efficiency Measures: Over the years, significant focus has been given to reduce the energy consumption of our locations by bringing in various operational efficiency measures in our operation. These measures include 1. Better operation controls for priority areas of operations like chillers, water systems and installation of timer controls to avoid unnecessary usage 2. Retrofit of older equipment with more energy efficient equipment 3. Consolidation of operations accompanied by a transition from leased to owned facilities with the resulting increase in overall utilization of office space 4. Higher quality maintenance operations. These initiatives have helped save 26 Mn KwH units in the reporting year.
- Others: There is a significant reduction in Scope 1 India emissions (by 40%) due to shift from DG to Grid electricity at our Chennai facility, post commissioning of an electricity grid substation by the state government. Data center India emissions have also reduced by 48% compared to last year, as one of the units of a data center is not operational.
- Strategic procurement: For the reporting period 2016- 17, RE contributed to approximately 25% of our total India energy consumption. We procured 96 Mn. units of Renewable energy through the PPAs (Power Purchase agreements) with private producers, against our target of 95 Mn units for the reporting year. Out of this, the zero carbon RE accounting is considered for 76.5 Mn units, as for this the green attributes have either been retired or are traceable to Wipro. This has been done by including non-tradability of Renewable Energy Certificate (REC) for contracted power through contracts and including verification of generation in the regulators national REC registry. This has helped mitigate 62.7 tons of CO2 equiv.
- In-situ renewable energy use: The pilot rooftop Solar PV installations at 3 of our campuses followed by extensive use of solar water heaters in our guest blocks and cafeterias have resulted in equivalent savings of 1.3 Mn units of grid electricity.
The IT services outsourcing model require frequent travel to customer locations, mainly overseas, across the delivery life cycle and contributes to around 1/4th of our overall emissions footprint. This includes travel by air, bus, train, local conveyance and hotel stays. Policies on usage of different modes of travel based on distance, time taken, need and business unit budget-based travel approval with increasing focus on processes which enable remote working and collaboration are some of the cost and process optimization measures implemented over past few years. We have seen an air travel footprint reduction (distance as well as emissions) reduction of over 19% compare to 2015-16. In association with a partner, we have conducted a detailed airline and business unit level of emissions intensities for the last two years. We plan to incorporate some of the recommendations in the booking process of travel agents and employees.
Employees have various choices for commuting are driven primarily by distance, flexibility, work timings, costs, city infrastructure and connectivity in the case of group or public transport. In addition to company arranged transport (41%), employees utilize public transport (~45%), with owned cars and two wheelers accounting for the balance. Over the past few years, we have taken steps to facilitate a shift towards improved access to public transport for employees (buses, commuter trains), carpooling, apart from encouraging cycling to work through an active cycling community in the organization. A mobile app based car-pooling initiative launched across four of our large locations in July 2016, in association with partners, has 14000 users and has resulted in reduction of 146 tons of CO2 equiv. in the reporting period.
IT led soft infrastructure enablers like anytime direct connectivity access to office intranet applications, secure personal device connectivity through the BYOD initiative (Bring Your Own Devices) are steps in enabling more flexible work place options.
