    EXECUTIVE SUMMARY

    Enterprises are increasingly going green, and looking to IT operations to help them reduce corporate

    energy consumption and become more environmentally responsible. Some IT shops are responding

    by seeking help from professional services providers that assess, plan, and implement green initiatives

    for procurement, operation, and disposal of IT assets and processes. Strategists at a broad set of IT

    services providers from data center specialists like HP and Intel to corporate strategy consultants like

    Accenture and Deloitte are positioning to participate in this nascent market, which we project willpeak at $4.8 billion in user spending in 2013 before gradually declining thereaer.

    A NEW FRONTIER FOR IT SERVICES PROVIDERS HELP FOR IT SHOPS GOING GREEN

    Corporate IT organizations are feeling increasing pressure, and finding growing opportunities,

    to improve their sustainability practices. Driven by a combination of cost savings imperatives,

    corporate green initiatives, and technology refresh opportunities, enterprise IT shops are going

    green, and looking for help to do so.1 IT services providers are responding by building capabilities,

    forming alliances, and positioning their resources to capture mindshare and wallet share of user

    companies putting green IT initiatives in place. We call this new market green IT services, and

    define it as:

    Consulting services that help enterprise IT organizations reduce their companies environmental

    impact by assessing, planning, and implementing initiatives that make the procurement, operation,

    and disposal of IT assets more environmentally responsible.

    In October 2007, we conducted a global green IT survey in which we asked IT professionals whetherthey used professional services providers to assist in the planning and implementation of green IT

    policies and practices.2 Six percent of the 130 respondents told us they were currently using a green IT

    services provider, another 6% were planning to, and 18% were considering hiring one (see Figure 1).

    With just a sliver of companies currently engaging a green IT services provider, this is clearly a

    nascent market. e purpose of this report is to help strategists at IT services providers position for

    growth by sketching out the markets future dimensions and assessing the breadth of capabilities of

    some of the important players shaping that growth. e report concludes that:

    e green IT services market will grow rapidly to nearly $5 billion. From a standing start,we project the overall market for green IT services to peak at $4.8 billion in 2013, half thatspending by European enterprises. Aer 2013, the market will decline, as most companies will

    have completed their initial round of green IT implementations.

    Assessments are the hook, tech implementations the big catch. Initial assessments of ITsenvironmental and energy footprint are the basis for green IT services engagements, but they

    are small projects relative to the technology selection and implementation that will oen follow.

    e implementation phase of green IT services engagements will account for 65% of total

    market revenues in the coming years.

    Services providers with a corporate strategy perspective are the likely long-term winners.

    Most of the action in green IT today revolves around data center energy efficiency, and there is

    plenty of opportunity there for focused providers like Dell, HP, and Intel. But we think the long-

    run winners in this market will bring a holistic perspective to clients looking to incorporate IT

    into a corporatewide effort to improve environmental responsibility. Such an approach is being

    pioneered by services providers like Accenture, Deloitte, and EDS.

    WE PROJECT A PEAK OF $4.8 BILLION IN GREEN IT SERVICES SPENDING IN 2013

    From a standing start of around $500 million in 2008, enterprise user spending for green IT services

    will grow by 60% annually to reach $4.8 billion in 2013. Aer that, the market will slowly decline, as

    most companies will have completed their implementation of green IT practices and technologies.

    In the context of an estimated $170 billion North American market for IT consulting and systems

    integration in 2013, the $5 billion market for green IT services might look like small potatoes to

    vendor strategists.3 But we expect the visibility and strategic importance of green IT projects toput them near the top of many corporations consulting agendas, and that service providers will

    aggressively compete for such high-profile wins.

    European Companies Lead, Asia Pacific Lags

    e growth of enterprise spending on green IT services will vary considerably by geography. In

    particular:

    Adoption and spending will grow fastest in Europe. Companies there are clearly taking thethreat of business disruption from the effects of climate change more seriously, and moving

    their awareness into action more quickly, than companies in other parts of the world. As a result,we expect green IT services spend by European enterprises to be roughly double that of US

    companies in 2009, and to continue to exceed that in the US market by a considerable margin

    through the forecast period, hitting a peak of $2.1 billion in 2013 (see Figure 2).

    North American enterprises will start a little later. e slightly larger North Americanenterprise population will begin adopting later than its Europe counterpart, but maintain the

    same growth rate during our forecast period, crossing the $1 billion mark one year aer the

    European market, and peaking at $2.2 billion in 2014.

    Asia Pacific (AP) companies will lag. Adoption of green IT services in the major countries ofAP will lag that in the other geographies considerably, reaching $760 million in 2014, about one-

    third the spending level of North American companies that year. We expect the AP market for

    green IT services to continue to grow beyond our forecast period, peaking in 2015 or 2016, and

    then beginning to decline.

    Some Industries Are Ripe Today

    e nascent state of the green IT services market makes detailed forecasts of adoption by industryimpractical. Some clear trends about early adopters were apparent from our interviews with vendors,

    however. Industry segments that are likely to be among the earlier adopters include:

    Government agencies. e public sector, especially in the UK, faces strict data and reportingrequirements for carbon emissions and energy usage. Similar regulations are likely to spread

    across the EU, and then to North America, over the next several years. Accenture and BT,

    among other suppliers, are seeing early demand from local and national agencies in the UK;

    EDS is seeing pioneering moves by government clients in Australia and New Zealand.

    Energy and resources companies. Not surprisingly given their direct participation in carbonregulation and policy, utilities and oil and gas companies are among the early movers in

    assessing and improving the sustainability of their internal operations.

    IT-intensive sectors. e usual suspects of financial services, telecom, and pharma wereoen cited in our interviews as companies facing limits on growth due to power provisioning,

    cost, and/or tight real estate in their data centers. Services providers focused on data center

    environments like HP, Intel, and Sun were particularly keen about their prospects in firms like

    finance and telecom that are reliant on giant data center operations.

    Big consumer brands and retailers. Companies with prominent, consumer-facing brandswere mentioned as likely candidates for green initiatives owing to their desire to maintain and

    improve their social-responsibility credentials.

    THE SHAPE OF GREEN IT SERVICES ENGAGEMENTS

    Green IT services engagements, like most consulting work, are bespoken projects tailored to clients

    circumstances, goals, and budgets. Nevertheless, its possible to characterize the general shape of green

    IT engagements in terms of three interlocking phases: assessment, planning, and implementation

    (see Figure 3). Assessment, the crucial first step for any company, involves relatively small, short-

    duration projects. Developing a strategic plan comes next. We expect that 50% of companies that

    hire consultants for assessment will move into the more detailed planning phase. And 75% of those

    companies will move to implementation, in which projects are typically much longer and more costly.

    Phase One: Assessment Provides The Baseline

    Companies green IT initiatives start with an assessment of their current situation.4 Consulting

    engagements in this phase typically involve:

    Creating an overall green IT plan. e scope will vary depending on the clients goals. Forexample, sometimes the plan is confined to data center operations, whereas other projects will

    involve a holistic, corporatewide evaluation along the lines of BTs carbon impact assessment

    that looks at buildings, IT, commuting, and travel. e key output of phase one will be an overall

    plan that sets the companys goals, defining priorities in terms of, for example, carbon emission

    reduction, energy efficiency, and cost savings.

    Modeling the return on investment. e plan will include an early assessment of the capital,operating expense, and potential cost savings of green IT initiatives.

    Managing a six week, $50,000 project. Vendors complete this phase in anywhere from two to10 weeks, for price tags ranging from $30,000 to upwards of $100,000. Although relatively small

    engagements from the providers perspective, they are the gateway to the larger planning and

    implementation phases.

    Phase Two: Planning Detailed Initiatives

    In this phase, consultants will help clients develop road maps for specific green IT initiatives,

    choosing and prioritizing based on the plan developed in phase one. Client companies will choose

    from a menu of initiatives, and end up with a second-phase engagement that might involve:

    Greening IT procurement and recycling. e project team will recommend policies forreorienting IT procurement towards greener products and greener suppliers, and draw up

    specific dimensions for expanded recycling programs for consumable and durable IT assets.

    Improving data center efficiency. Clients and services providers will choose among myriadinitiatives for optimizing energy use in corporate data centers, yielding a roadmap for

    implementing, for example, server virtualization and consolidation, an enhanced power and

    cooling infrastructure, and more energy-efficient server, storage, and network gear. For some

    services providers and their clients, outsourcing data center operations and infrastructure will

    be on the table in this conversation.

    Positioning IT to support green business. Depending on a projects scope, green IT servicesmight involve helping the IT organization help the rest of the business go green. IT expertise

    and infrastructure will be crucial in initiatives for building automation, optimizing the supply

    chain or logistics, or setting up flexible work environments that reduce employee commuting.

    Running a 12-week, $250,000 project. We found an even wider range of experience and estimatesfor the planning phase, ranging from six weeks to 20 weeks with $50,000 to $400,000 price tags.

    Phase Three: Implementation Makes It Happen

    In the implementation phase, consultants and clients work to specify, purchase, and install

    appropriate technology products and soware. Depending on the nature and scope of the

    engagement, this phase might be solely about implementing new technology (virtualization in a

    data center for example), or include new processes, policies, and employee practices, which are

    oen as hard or harder to implement than new server architectures or cooling infrastructure. e

    implementation phase is:

    e longest and most costly part of a green IT services engagement. Typical timeframes runfrom 30 weeks to more than 100 weeks, with price tags from $300,000 to $2 million or more.

    Note that this is services spending only; it does not include the cost of soware licenses and new

    hardware.

    Where the real revenue opportunity lies. Implementation projects are by far the largest part ofthe market opportunity for green IT services providers (see Figure 4).

    MAPPING SERVICES PROVIDER CAPABILITIES

    Forrester interviewed a cross-section of IT services providers to understand their priorities in

    developing green IT practices. is is not a comprehensive list or evaluation of green IT services

    suppliers, but rather a sampling intended to offer a first scan of capabilities of some of the

    prospectively important players in this nascent market.

    Vendors Bring A Variety Of Green IT Services From Different Angles

    Although all these suppliers are looking to leverage their internal expertise and experience in

    sustainable IT operations, they approach the green IT services market from different angles and

    experience bases. ey can be generally categorized as:

    Services arms of IT system manufacturers (Dell, HP, Intel, and Sun). ese vendorsservices practices are pretty tightly tied to their product offerings, hence, tend to be focused

    on data center design and optimization. Sun has some broader capabilities that stretch into ITprocurement and recycling processes.

    IT systems integrators/outsourcers (CSC, EDS, Getronics, and Wipro). Getronics and Wiproare data center-oriented; CSC and EDS have broader visions of corporate green initiatives and

    ITs role within them. All see data center outsourcing as an avenue to reducing the corporate

    carbon footprint.

    IT consulting giants (Accenture, Deloitte, and IBM). ese providers take a broad, top-downview of green IT services. Although they have data center expertise, they approach IT from the

    corporate sustainability and CSR perspectives, helping clients position IT as an enabler of and

    contributor to wide-ranging green business initiatives.

    Telecom services supplier (BT). BT is seeking to leverage its extensive internal experience ingreening data centers and in planning a corporatewide approach to sustainability.

    More important than where they come from is the providers focus in terms of helping enterprise

    clients address their green IT challenges and opportunities. We have positioned each services

    provider along a spectrum between two poles (see Figure 5):

    Data center-focused. Suppliers on the le side of the spectrum are focused on clients data

    center operations. ey have specific and deep expertise and experience in and tools forimproving the efficiency and mitigating the environmental impacts of data centers.

    Corporate sustainability-focused. ese suppliers usually have data center expertise, but theirgreen IT practice and offerings range more broadly across IT and other corporate processes.

    eir consulting offerings typically go beyond technology to include organizational change,

    procurement policies, and helping IT enable greener business practices in areas like supply

    chain optimization or building automation.

    Vendor Strategists Must Address The Data Center Today, The Entire Business Tomorrow

    Like most IT services markets, green IT will grow as more enabling hardware and soware products

    become available and user companies look for help in choosing among and implementing them.

    Today, such products are in the data center (such as server virtualization and power management);tomorrow, they will spread to other parts of a companys operations (like facilities, supply chain, and

    IT assets outside the data center). As this evolution unfolds, the best-positioned service providers

    will be those with a holistic perspective on ITs role in corporate sustainability.

    Strategists and practice leaders at green IT services providers should anticipate these developments

    in the markets evolution:

    e data center stays hot. When we say green IT, most enterprise clients hear data centerefficiency. Its top-of-mind for most clients because problems like growth or power capacity

    limits, and returns like energy cost savings, are highly tangible.5 Every supplier we interviewed

    had capabilities to help clients optimize their current data centers and design new ones.

    Although this part of the market will be crowded, there will be plenty of work as a wave of data

    center optimization and consolidation ripples through corporate IT.6

    Other IT infrastructure will heat up, too. Although IT organizations typically use (and waste)at least as much power outside the data center as inside, capabilities to help clients improve

    PC and peripheral energy efficiency were considerably less common among this set of services

    providers.7 Advice on managed print services, for example, is offered by fewer than half of these

    suppliers. e energy usage and efficiency of PC populations, printers, and the like is harder for

    companies to measure, and harder to control, than the concentrated and tightly managed ITassets in the data center environment. is will translate over time into a significant opportunity

    for consulting providers.

    Procurement and recycling will get more attention. Relatively few of the services providersin our sample offer advice and planning for clients seeking to make IT procurement or

    recycling efforts greener. We see green criteria in procurement as one of the most visible signs

    of increasing action by enterprises to reduce the environmental footprint of IT operations, but

    fewer than half the suppliers we interviewed offer help for companies in this area. As this market

    matures, we look for the services providers to broaden their focus from optimizing energy usage

    to include both the beginning and end of IT assets life cycles.

    Management soware will be a growth frontier. Much of the vendor activity in green IT isclosely tied to hardware systems like lower-power processors or storage devices. Whats gotten

    less attention so far is the soware side of things, especially in systems management consoles

    that can integrate information from the growing collection of asset management, power

    management, virtualization, and workload management systems. Tying these IT capabilities to

    broader soware systems for building management and carbon measuring and reporting, and

    linking these to mainstream corporate ERP, is another frontier for the services providers in

    green IT.

    Linking IT to other business processes is the ultimate opportunity. We have thought for sometime that the real promise of green IT is actually outside the IT organization and asset base. ITwill be an enabler for a much broader set of green business processes in supply chain, workforce

    management, collaboration, and facilities. e services providers offer a checkerboard of

    capabilities in these areas, which we expect will receive much more attention from providers

    and their clients as sustainability continues to rise on the overall corporate agenda and the role

    of IT as an enabler becomes clearer.

    STRATEGISTS FACE POSITIONING AND GROWTH DECISIONS

    Enterprise clients will be pursuing green IT initiatives from one of two directions: bottom-

    up, driven by tactical cost and availability concerns; or top-down, motivated by corporate

    sustainability and CSR considerations. Services providers must decide which of these avenues

    they can support, and how best to build a thriving green IT services practice, by:

    Listening to clients. Strategists should tap into clients preferences by conducting focusgroups or informal polls. CSC recently completed a study tour of large clients in the high-

    tech industry to help inform its resource planning for green IT services.

    Deepening expertise. We expect services providers to place their bets on specific nichesthrough acquisitions. For example, HPs pending buy of EYP Mission Critical Facilities gives it

    an additional 350 experts in data center design and optimization.8

    Creating a hybrid organizational structure. Most services providers are trying todecide whether to build a dedicated green practice or infuse green expertise across their

    mainstream IT practices. The best approach for the next several years will be to do both,

    build a small nucleus of green expertise that links to other practices like data center, supply

    chain, and procurement.

    Clarifying clients entry points. Most of the industrys green IT practices need morecoherence about what they offer, and to be clear that there are multiple ways for clients to

    get started on a holistic sustainability program.
