Social Value

Fighting climate change

Fighting climate change

Fighting climate change
1. TCS commits (and is on track) to reduce absolute Scope 1+ Scope 2 emissions by 70% by 2025, achieving Net Zero by 2030 or earlier, and to working with customers to achieve this.
2. UK&I Carbon reduction plan signed at board level.
3. We shall continue this approach under G-Cloud 13, aligned with TCS corporate policies:
a. “Beyond Compliance” Environmental Sustainability Policy: proactive engagement with governmental and other agencies to design and drive environmental policy and regulation.
b. Green Procurement Policy: all TCS consider life-cycle cost and potential environment impact of products and services.
c. Climate Change Policy: all Tata companies to set carbon footprint benchmark within their industry.
d. Sustainable Supply Chain Policy: establishing good environmental, social and governance practices within supply chain.
4. Our commitment is evidenced by the following:
a. Organisation-specific energy consumption reduced >60% since 2008
b. Reduced greenhouse gas emissions (Scopes 1 + 2) by 61.8% since 2008 (3 tCO2E/FTE/Annum to 1.15 tCO2e/FTE/Annum in FY 2020)
c. Reduced specific energy consumption YoY by 11.9%; specific carbon footprint down 11.8%.
d. 31% renewable sources electricity powering UK offices.
e. 35% of UK properties divert all waste from landfill.
f. 100% UK properties with extensive waste recycling programmes.
g. >60% of real estate portfolio certified green building space, 80% of owned real estate IGBC/LEED-certified green infrastructure.
h. Freshwater consumption down 5.5% (2019) and by 19.4% over baseline year.
i. Reduced business air travel carbon footprint in FY2020 by >67% over baseline year and by 19% over FY2019.
5. We minimise non-essential travel through agile, flexible approaches, supported by “Vision 25x25” (by 2025 <25% employees will attend a TCS facility at a point in time; nobody will need to spend >25% of time at a facility to be 100% productive).
Covid-19 recovery

Covid-19 recovery

Covid-19 recovery
1. To aid Covid-19 recovery we seek opportunities to work with local partners and training providers in our contracts.
2. We operate in locations around the UK and are committed to supporting these local communities. We have local SME supply chains to invest in those communities.
3. We partner qualified training organisations, local colleges and universities to offer a range of Apprenticeships from Level 2-7. Current examples of established programmes with customers include Diligenta, Scottish Power and PwC. We provide apprenticeships, placements and internships. We currently employ 95 apprentices in the UK, through a variety of education establishments and engage 5 or 6 per annum. Apprentices enjoy access to our training portal, which contains thousands of IT courses supporting developing career aspirations. On completion, participants are encouraged to apply for employment with TCS, where suitable openings are available.
4. This provides value for the workforce, our customers, local communities and TCS.
a. Individuals benefit from enhanced skills relevant to their role, increased job satisfaction, higher market value - in TCS and externally.
b. Customers benefit from high-quality service delivered by skilled, motivated, engaged employees.
c. Local communities benefit through employment and training schemes.
5. We shall continue this approach for all G-Cloud 13contracts, seeking opportunities for level 2, 3 or 4+ apprenticeships for 1 year in relevant technical disciplines. This recognises the impact of Covid-19 young people seeking employment. Progress will be reviewed each term against pre-defined criteria and will include participant feedback.
6. We shall run other initiatives, including workshops in partnership with local Job Centres, for people unemployed due to Covid-19. This provides mentoring in IT career opportunities, training and skills suggestions, CV creation and interview preparation. We shall ensure people interested in IT opportunities receive information on forthcoming TCS vacancies.
Tackling economic inequality

Tackling economic inequality

Tackling economic inequality
1. We have a modular and flexible approach to tackling economic inequality. Ongoing initiatives include:
a. Recruiting long-term unemployed people and/or those facing other barriers to work, for at least one year, offering a broad-based and comprehensive training scheme to establish experience in work, develop knowledge and build confidence;
b. Providing business/IT expertise and guidance each year for local businesses with specific emphasis on overcoming inequality in the supply chain and identifying new opportunities from which they can profit;
c. Setting up Innovation Forums for local SMEs/MSMEs, start-ups and entrepreneurs to share learning and development, and consider relevant innovation in technology. TCS’ Co-Innovation Network (COIN™) brings together universities, industry experts, start-ups and entrepreneurs to conceptualise breakthrough solutions. It consists of over 2,400 start-ups globally. The Academic COIN™ programme has 67 active partnerships.
2. TCS will commit to the 30% threshold for SME revenue as part of this contract and will tackle inequality through a number of initiatives and approaches, including:

b. Streamlining the procurement process (whilst maintaining quality) to reduce the overheads for SMEs, ensure opportunities are available well in advance with clear requirements to allow planning;
c. Selecting suppliers from the supply chain via fair, open, transparent competition;
d. Establishing and developing relationships and contractual arrangements with our supply chain in line with PPN 01/18 Supply Chain Visibility;
e. Providing consistent and timely information on current and future opportunities, and working with SMEs to identify and engage with new opportunities;

2. We ensure business leadership accountability for D&I. We will align actions for G-Cloud 13 contracts with our UK strategy and report progress to our Advisory Council, chaired by our Head of Legal and Inclusion Champion.
3. We work with multiple disadvantaged groups. An ongoing success is our support for our female workforce: while the IT industry continues to attract very low numbers of women (around 17% of the workforce), TCS employs over 36% women associates across the organisation (FY21).
4. TCS is a Disability Confident Committed employer, working closely with the Business Disability Forum to recruit and support disabled employees.
5. We are committed to attracting more diverse talent through:
a. Proactive hiring strategy at junior level to create a growing pool of female talent in TCS (currently have > 40% women in junior grades)

e. Encourage employees to access EAP, or self-help tool kits available via our UK social network.

a. Regular health screening.
b. First aid facility in all delivery locations.
c. Ergonomics instruction pop-ups on users’ PCs every 15 mins to give advice on rest and safe use.
