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:

HCL: Improving our Eco Footprint
  • 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.

All Greenhouse Gas (GHG) emissions figures in the report are in tonnes of carbon dioxide equivalents (CO2e) which include Carbon dioxide (CO2), Methane (CH4), and Nitrous oxide (N2O). And other Perfluorocarbons (PFCs), Hydrofluorocarbons (HFCs) & Sulphur hexafuoride (SF6) emissions have not been reported since they are not significant to the operations. The Scope / boundary of the yearly GHG emission reporting covers HCLT’s PAN India and Global Operations, and Global Operations covering Israel, Japan, New Zealand and Poland. This includes three business segments:  Software, Infrastucture Management (Infra) and Business Process Outsourcing Services. (BSERV)

Emissions Data

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.

Emission Data 2

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.

HCL: Water Sustance

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.

All new HCLT office facilities in India have Sewage Treatment Plants (STP). The treated effluent from the STP is tested regularly against various national and state effluent standards and recycled for use in HVAC System cooling tower, washroom flushing and gardening. 
During FY 12, we treated and reused 0.19 million cubic meters of water. We also continue with installing Rain Water Harvesting (RWH) plants  in offices with significant operations. 
This year, our focus was on measuring water footprint source wise; going forward we shall devise ways of our impacts on community water share/reduction at source per se in all our India-based facilities. Facilities which do not have a STP, are discharging waste water in municipal drains. Company-owned facilities with 2000+ employees in India which have both STP and RWH systems are as follows: Chennai (all facilities), Noida (all facilities) and Gurgaon (all facilities). 

Paper Consumption

HCL: Paper ConsumptionPaper is an operational consumable at HCLT. To reduce our dependence on paper, we launched a ‘Printer Holiday’ initiative.  The printer is given a Holiday for 2 days every month which has resulted in a paper-saving by 17% and has contributed to saving approximately 500 trees.

Consumption Data
  Reams for FY 12 Reams for FY 11
Infra 6,803 -
Apps 30,815 -
BPO 4,167 -
Total 41,785 50,469
Scope: HCLT, India Operations

HCL: Paper Consumption 1Currently 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.

Managing E-Waste

For E-Waste management, we are guided by an organization-wide policy and processes. We work with licensed vendors who are certified by the Pollution Control Board in India for removal of E-waste. We also audit the vendor process on a periodic basis. The E-waste generated at the various HCLT facilities include defunct computers, monitors, servers and allied hardware. In FY 2012, 139864 kg of equipment from our India based offices, amounting to E-waste were disposed through authorized handlers and recyclers.

Scope: HCLT, India based locations

Hazardous Waste 

Hazardous wastes are disposed of as per the Ministry of Environment and Forests’ (MoEF) Hazardous Waste Handling and Management Rules, through MoEF-authorized vendors only. This is overseen in some states by the local pollution control boards. 
Used Lube oil (left out from DG maintenance) is the main hazardous waste material which we have, and total volume figures for the same are 54.524 KL for our India-based facilities. We did not have any incidents of diesel or waste oil spills in any of our centers this year.
We are aware that it is important to partner with multiple stakeholders meaningfully to manage day-to-day operational wastes. For example, when our vendors supply us with major equipment, they are requested to remove cardboard and polystyrene packaging material from the office premises.
