Our primary source of electricity is the grid, with diesel generator sets used for back-up power supply during power outages. Some TCS offices have provision for roof-top solar energy generation, and at some offices ‘green power’ is procured through open access (hydroelectric or wind power). Some overseas locations use fuel for space heating. The total electricity consumed in FY 2016 is 592,323 MWh (2,312,683 GJ). The total direct energy consumption by primary energy sources is 277,391 GJ (from fuel consumption in owned vehicles, diesel consumption in diesel generators, combustion of cooking gas, and space heating).
- The sources of GHG emissions contributing to TCS’ carbon footprint are:
- Scope 1: Diesel generator sets, company-owned vehicles, refrigerant gas (fugitive) emissions, cooking gas combustion, and fuel combustion for space heating
- Scope 2: Purchased electricity
TCS strives to manage its energy and carbon footprint focusing on four key levers – green buildings, green IT, operational efficiency, and renewable energy.
The combined GHG emission (Scope 1 + Scope 2) was 1.69 tCO2e/FTE in FY 2016 as compared to 1.82 tCO2e/FTE in the last financial year; 43.6% less than the baseline year 2008 and 7% less than the last reporting year.
