Improving our Eco footprint
Improving our Eco footprint: Reducing carbon emissions
The following improvements were done this year in line with our commitment to Renewing our Ecosystem:
- Integrated sustainability requirements with our existing infrastructure plan. This includes: improving indoor air quality, managing water- treatment units, using refrigerant gases which are not harmful to the ozone layer, incorporating energy-efficient lighting fixtures and LED lights in some of our offices and providing collection and storage space for recyclable material.
- Replaced CRT monitors with power-efficient TFT monitors. Reduced the usage of large monitors wherever possible. A 17” monitor uses 35% more power than a 14”monitor.
- Introduced Inkjet printers, which use 90% less power than laser printers. Printers and copiers were powered off during nights and week-ends.
- Installed air-conditioning control based on programmable thermostats for new office buildings.
- Ensured that private offices and common areas have reduced power-based lighting.
- Installed Tele-presence system in select locations to reduce the need for business travel.
- Planted 6500+ trees across India.
- Piloted the usage of recycled water for earth-pits that are used for watering plants and basic washing and cleaning purposes. This conserves electricity as well.
Emission Calculation Methodology
We prepare our GHG emissions inventory in accordance with ‘The Greenhouse Gas Protocol: A corporate accounting and reporting standard’ and ISO 14064: 2006 – ‘Greenhouse gases, Part 1: Specification with guidance at the organization level for quantification and reporting of greenhouse gas emissions and removals’. We measure our GHG emissions as total GHG emissions in tonnes of Carbon dioxide (CO2) equivalent.
The carbon dioxide emissions associated with the activities noted on the basis of measured or estimated energy and fuel use, multiplied by significant carbon emission factors. Published National factors were used to calculate emissions from operations. In the absence of any such national data, IPCC and DEFRA’s Greenhouse Gas Conversion Factors for Company Reporting have been used for the calculation of GHG emissions.
The absolute energy consumption this year is 13,17,217 GJ (which is direct and indirect energy combined), but the per capita emissions stand at 2.37 tCo2 - employee which is 17% less than last year. Facilities, where there are significant risks are monitored for emissions of DG sets for NOx, SOx and other particulate matter at a specified frequency.
The emissions are within Central Pollution Control Board (CPCB) approved limits with the tests carried out by certified vendors. Since a few locations are not capturing the emission data currently, the same will be quantified in next year’s report.
Total Ozone Depleting Substance (ODS) refilling across India-based locations was 11.3375 MT which contributed to ozone-depletion to the magnitude of 0.59 ChloroFluro Carbons (CFC) equivalent. We believe in taking precautionary measures and promote the usage of Ozone Depleting Potential (ODP) free refrigerants.
For GHG emissions, our operational boundary covers five categories of activity sources which are listed below,
|Emission||Scope||Emission Source||Emissions Activity|
|Onsite electricity generation – Diesel fuel||Core Direct (Scope 1)||DG Sets||CO2, CH4, N2O|
|Purchased Electricity||Core Indirect (Scope 2)||Facility use||CO2, CH4, N2O|
|Business Travel Road||Optional Indirect (Scope 3)||Vendor vehicles / Leased Buses||CO2, CH4, N2O|
|Business Travel– Air Domestic||Optional Indirect (Scope 3)||Commercial Airlines||CO2, CH4, N2O|
|Business Travel-Air International||Optional Indirect (Scope 3)||Commercial Airlines||CO2, CH4, N2O|
We have developed an inhouse tool ‘Manage Carbon’ which helps to measure, report and mange GHG emissions.
Carbon Emissions: Scope Wise
|Onsite Electricity Generation - Diesel Fuel||24%||49%||52%|
|Business Travel and Employee Commute||60%||37%||22%|
Carbon Emissions: Business Wise
|Total Emissions (tCO2e) x 1000||170.15||243.708||218.92|
Total Emissions (tCO2e) x 1000
Direct and Indirect Energy
|Direct Energy (GJ ) (Electricity generated through Diesel)||
|Indirect Energy (GJ) (Purchased Electricity)||471989||551307||548636|
Scope: HCLT India + 5 Global Delivery Centers
Our absolute emissions have reduced from the previous year because of a reduction in Scope 3 emissions. This us due to a reduction in employee travel due to use of alternative technologies like video-confering etc.
Improving our Eco footprint: Water Sustenance
In FY 2012, we institutionalized basic processes to measure and monitor water usage across India based office locations. A source-wise breakup of the 0.83 million cubic meter of water consumed this year is shown below.
Our primary sources of water are both bore wells (ground water) and purchased water from the local Government and other vendors. For ground water consumption, we have made an assumption that wherever borewell meters are not installed, per person consumption of water is 40 L per day.

Currently we use virgin paper for our printing activities in all our facilities across the globe. Going forward, we plan to use recycled or partially recycled paper for company-wide internal branding and printing activities.
