HCL's energy conservation initiatives
HCL eco Safe Policy clearly recognizes the importance of products  that are energy efficient and help customers cut costs of ownership and attain broader goals of protecting the environment. All our products have been incorporated with Green PC features and ACPI mode for power saving.
All our manufacturing facilities practice various measure to reduce power consumption by using natural light during daytime, installing different capacities DG sets that consumes optimum amount of diesel as per required load.
HCL strongly advocates that India needs Energy Efficiency 'regulations' for future industrial and economic growth.
Today, our country's per capita emissions are only a fraction of those in developed countries. By foreseeing the level of industrial growth in the near future, HCL strongly advocates that India needs Energy Efficiency 'regulations' for future industrial and economic growth.On account of global warming and the acute energy shortage faced by our nation, HCL has committed towards
- Organising tree plantation programme to combat greenhouse gas emissions
- Strongly supports all the initiatives of the Indian Government in favour of GHG emission reductions
HCL policy in support of GHG reduction
The Rio Declaration on Environment and Development highlighted the need and action plan to regulate Greenhouse Gas (GHG) emissions which have a direct impact on climate change. Under the Kyoto Protocol, signatory countries are required to reduce their combined GHG emissions by 5% from 1990 levels between 2008 and 2012.
India signed and ratified the Kyoto Protocol in 2002. Though India is exempted from the framework of the treaty, however it is supposed to gain from the treaty in the form transfer of technology and other investments measures. Since India has obligation towards the principle of common but differentiated responsibility, hence HCL fully supports this position. India maintains that the major responsibility to curb the emissions rests with developed countries, which have accumulated emissions over a period of time.
With growing pace of Indian economy, HCL visualizes the future and would take proactive action towards the Kyoto protocol. HCL is fully committed to reduce its GHG emissions within a certain timeframe. HCL, as a policy, supports Kyoto Protocol by acting as a proactive player to reduce the GHG emissions. HCL would support a low carbon economy and would take measures to cut its own direct emissions to start with. To visualize this vision, HCL already had taken measures to use energy efficient products both directly and indirectly. HCL has participated in many Government/Industry initiated programmes on GHG reduction.
HCL would work towards a low carbon economy and therefore demands from Government of India to have Energy Efficiency Regulations. HCL would proactively work with all stockholders including Government and industry to make level playing field on Energy Efficiency Regulations.

Carbon Footprint disclosure
Primary to HCL's strategy to reduce the environmental impact of its operations is its commitment to improve energy efficiency and reduce carbon footprint. HCL has commenced working towards accomplishing this commitment. In order to conform to the requirements of international reporting, more robust data and management systems will be developed by HCL as delineated in the various protocols and accepted standards.
HCL will report its GHG emissions based on:
- The guidelines provided by "The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard", revised edition, 2004.
- "Sustainability Reporting Guidelines: G3", published by Global Reporting Initiative (GRI), 2006 and
- Relevant provisions of ISO 14064 on "Greenhouse Gas Quantification, Reporting and Verification" - Greenhouse gases - Part 1: Specification for the quantification, monitoring and reporting of organization emissions and removals
GHG emissions under Scope 1, Scope 2 and Scope 3 will be reported by HCL containing:
- Scope 1: Production of electricity, heat, or steam, physical or chemical processing / manufacture
- Scope 2: GHG emissions from imports of electricity, heat, or steam
- Scope 3: Indirect emissions
In line with our commitment towards a low carbon footprint ecosystem, we started collecting our GHG emission footprint from 2007 onwards.
We have been publishing our internally audited figures on scope 1 and scope 2 emissions since then.
To further consolidate our commitment towards a sustainable business conduct, we went one step ahead and commissioned Deloitte – a reputed name in the field of GHG report auditing- for assuring the authenticity of our publically stated GHG emission figures for FY 2008-09. This rigorous exercise, which involved 210 sites of HCL Infosystems (spread across the country) has been performed in accordance with the ISAE-3000 standard. We are happy to announce that the Auditors are satisfied with HCL’s estimate of GHG emitted for the period of July 2008 – June 2009.

In future we will strive to expand the scope of GHG emissions, and will further keep on improving our systems on the data – accumulation, review and reduction of GHG emissions. We will include the scope 3(indirect) emissions in our next GHG emission report, and will keep you updating on this front from time to time.

Own GHG emissions reduction commitment
Taking 2007-08 as our base-year, we have taken a very aggressive target of 20% reduction of our GHG emissions by 2014 for all our existing locations.
Road-Map for GHG reduction:
We have a well planned road map for achieving this challenging target. Five projects have been started in this direction, which have started working towards the following 6 projects with dedicated people from Admin, marketing, commercial and procurement departments:
1. All new locations will be green buildings
2. More Use of solar energy (doubling the current proportion of solar energy from 0.13% to 0.26% of our overall energy consumption)
3. Installation of energy saver ACs (estimated reduction of 5% electricity consumption for each unit)
4. Replacement of tube lights with more efficient LED lights
5. Replacement of CRTs with TFTs
6. Replacement of normal SMPS with energy star SMPS
Examples of energy saving initiatives:
In out Pantnagar plant, we have implemented the following energy saving measures during 2006 and 2007:
- We monitor our power consumption daily to detect abnormal increase
- We maintain our equipment on a monthly basis to ensure it does not consume higher power than normal
- We practice switching off power consuming equipment when not required
- We use natural light for general lighting during daytime
- We use energy efficient metal halide, CFL lamps and electronic ballast for all lights which reduces power consumption
- No pumps have to be used for water withdrawal, since we have constructed an artisan bore well
- We installed different capacities of Diesel Generator sets to optimize diesel consumption. Diesel Generator sets are used as a back-up if GRID power is not available
- We use spot air conditioning as per requirement, instead of continuous, complete air-conditioning
- We have installed hot air exhaust systems in our Reliability Testing area, and under deck insulation in our production hall to reduce the AC requirement
- We have replaced AC with fans in our customer inspection area
- We have installed sun film on window glasses to reduce the heat load
- Through the installation of a capacitor bank, power consumption is reduced further

Energy Saving Measures Taken During 2008-2009 at other locations of HCL
- We have replaced 1715 nos (240 in Mumbai, 45 in Jaipur, 50 in Kolkata and rest at Noida offices) of Fluorescent tube lights and copper chokes with energy efficient T-5 lights and electronic chokes.
Energy consumed by FTL = 90 VA
Energy consumed by T-5 = 32 VA
Saving per light = 58VA
Total saving per month = 58/1000 x 1715 nos x 10 hr/day x 25days/month= 24867 units/month
- We have replaced 382 nos of CRT monitors with LCD monitors at Noida office.
Energy consumed by CRT= 0.65 A
Energy consumed by LCD monitor = 0.2 A
Total saving per month=0.45 x 220 V/1000 x 382 x 9 hr/day x 25 days/month= 8509 units/month
- We are switching off light at HCL offices at 7 pm, thrice per week. This has been a strict rule or all HCL offices since October 2008.
- At our UMO factory, we r switching off UPS at night and holidays, we have programmed conveyor lines to stop when not required, and we have replaced incandescent bulbs with CFL. Resultant saving is 8634 units/month.
- At PMO factory, we have replaced 91 nos of 250 w metal halide lamps with 125w lamps. Resultant saving is 2958 units/month.
- At Mumbai and Cochin office, we switch off AC units during lunch period. 1:30 to 2:30 pm daily.
- At Pune office, we do not need to switch on light during daytime, as sufficient natural light comes through windows.

Energy efficiency of new models
HCL Infosystems follows 2 steps for improving the energy efficiency of its green PC models:
- Choosing the right hardware for a green PC (e.g. using motherboards with Dynamic Energy Saver (DES) technology), and using more efficient power supplies (ES 4.0 and ES 5.0)
- Setting the right tuning of the software to support green computing
These methods have resulted in energy conservation of 20 to 33 % for our green PC models (depending on the model) and 75 % for the monitors.
The entire range of HCL products has ACPI mode for power savings, as well as UL certification for safety.
