Introduction

The program Green IT started in Fortis in September 2010. After exploration studiesand the definition of the approach plan, the Green IT program is now under preparation. Different Green IT projects have been identified at five different levels (sustainability, enterprise, IT organisation, IT automation & data center) that aim for the GREENING of IT.

Besides, possible future subjects of interest are investigated:• Green Projects Life Cycle• Green Software Development• Data Life Cycle• Etc.

The goal of this conference is to share a practical approach with the audience.

Having realised that not launching the GREEN IT project is not an option, BNPP Fortis is defining practical action plans. Together with Facility Department and Adjugo, a company specialised in IT & Green IT governance, the IT architecture organises & coordinates the activities to reach sustainable objectives.


Agenda

1 Green IT, a Major Concern

2 From Green Concept to Approach Plan

3 From Approach to Program: Assessment Results

4 From Now to Future: Strategic Subjects under Investigation

1.1 Greening IT is a priority

5 Conclusions

1.3 Some Key Figures


Green IT, a Major Concern

“Greening IT is a priority”


Sustainability Policy


Some key figures

ICT is estimated to be directly responsible for almost 2% of global CO² emissions.

This is roughly equivalent to the emissions of the aviation industry…


Agenda








1.2 Greener Data

5 Conclusions



• BNPPInternal items, we think there are a lot

• SuppliersEvery substancial IT supplier has an « Green » speech/marketing

• DemandDifference between communication and IT reality

• The academic sourceUniversities, blogs, publications

• From a software solutionExemple of SAP with EHS module (Environment, Health and Security + Clear

Standards)• Analysts

Each substancial cabinet of analysts has a practice dedicated to Green (Gartner, Forrester, IDC (our Nb 1), etc..)

Possible sources

Sustainability vs. Green

Divergent explorative phase


The concept of « 20% of the projects which will create 80% of potential profits » seems difficult to adopt, seeing the fragmentation of the issue

Clashing concepts, namely: ecology, durable, new generation of datacenters, etc.

A lot of information but barely workable at raw state

The economical crisis caused a diminution of Green IT projects (more than 6.000 articles in 2009, less than

5.000 in 2010)

The ecological aspect supports communication, while the financial aspect drives the IT reality

Short Observations


Two types of approach might to be interesting• The supply chain vision• The hourglass vision

The Quick Wins• Others’ examples• The Magic Quadrant

Incorporate the futur now• New datacenter(s) by 2013

It seems essential to initiate something

How do we proceed?


Maintaining in operational conditions costs 5 times more than purchasing.It is therefore important to aim the right target in durable objectives

Add electricity consumption in the «maintenance cost»

Initiatives

• Go further with normes (Ex : PUE Power Usage Effectiveness)• Add «durable» concept to each procurement request• Educate, inform, make people aware, etc.• Implement measures, objectives and a follow-up

Reduce foot print Produce less wastes

The Greening OF IT

• Increase datacenter and IT infrastructure efficiency,• Reduce paper consumption,• Reduce electronic waste,• Manage end of lifecycle of equipments,• Introduce green criteria in IT procurement,• Prepare for green project lifecycle or green software development, …

Most of the initiatives are not business dependent, can apply everywhere.Limited impact (internal)

Relatively easy to estimate the financial and environmental ROI.

The Greening BY IT

All IT projects and products allowing an organisation to reduce its global environmental footprint.

Some of the initiatives are not business dependent, most are.Unlimited impact (internal, external) and the path to a low carbon economy.

Complex ROI calculation, mid to long term investments.

• Home work and smart work center policy,• Web based videoconferencing,• Scanning and electronic document management,• E-government (tax on web, ID signature, …),• Truck fleet satellite management, …

Green IT

All actions taken by an organisation to make its IT more environmentally

friendly.

Green-IT StrategyThis proposal is perfectly in line with

the recommendations for an ‘Eco responsible IT organisation’as recommended by the WWF

• Rethink the information system by including environmental data

• Create awareness for users at all levels

• Extend hardware and software lifecycle

• Continue to save energy

• Manage end of lifecycle and waste

• Buy responsible

What do we see?

• Most Green-IT actions are taken at operational level only

• No holistic approach, no Green-IT strategy

• Focus is on internal IT (Greening OF IT), rather than reaching out to business andbeyond (Greening BY IT)

• Users and organizations not well informed on Green-IT best practices

• No formal Green-IT best practice framework exists to date

Action plan proposed

• Quick Wins

• Implementing a Green-IT strategy Define Green IT principles Setup Green IT board …

• Evaluate opportunity to implement ISO 14001 in IT andGreen-IT projects

• Define long term vision & structural changes

Green Projects Life Cycle and Software Development: Trade-offs

Energy Efficiency vs. Functionality• Non-essential features may lead to energy waste

• E.g.: continuous client-side reporting of server status

• E.g.: check spelling as you type, wizards (remember Clippy?)

Efficiency vs. Performance• Optimising for performance is not necessarily energy-efficient

• E.g.: guaranteed response times may require over-dimensioned hardware

Energy efficiency vs. Reuse and Adaptability• E.g.: Packaged solution may not allow application-specific optimisation

• E.g.: Loose coupling via web services may increase communication overhead



Green Projects Life Cycle and Software Development: Challenges

Maturity of software production processes• Need of awareness, commitment, communication, organisation

• Additional control variable in an already complex process

Attribution of energy consumption to applications• Hardware consumes energy to run applications

• Multiple applications run on multiple machines in parallel and/or interleaved

Attribution is hard and necessarily imprecise

Comparability between applications• Energy consumption must be seen in relation to delivered functionality

• Comparability only between functionally equivalent applications

Common standards is hard to define



Greener Data – What is the problem?

• The increase of data has not been looked upon as a problem, and its long term effects on organization are still not fully understood.

• Adding storage is an « easy fix » to a complex problem: storage is relatively inexpensive and getting less expensive.

• Enterprise are responsible for managing up to 85% of world’s data, 70% of this data is created by individuals.

• Compliance with industry, government and internal regulations is perhaps one of the most significant factors causing double digit data growth.


Greener data – 10 strategies to manage data growth

• Modernizing your data center:

Data Deletion Information life cycle management Tiered storage Archiving and Application retirement Improve data protection Data reduction Increase utilization rates: intelligence in the platform Intelligence in the platform: unified storage Intelligence in the plaftform: thin provisioning Alternative delivery methods: cloud and SaaS

Agenda








1.2 Greener Data

5 Conclusions



The benefits of a management Green-IT (OF/BY) strategy are multiple and involve allstakeholders

• Immediate and future ROI• Improved corporate branding / image• High shareholder value / satisfaction• CO2 and waste emissions reporting• Anticipate regulations / avoid penalties• In line with company’s CSR mission

A Green-IT approach build around continuous improvementand innovation inside and for the organizations.

• New business opportunities• A trigger for growth • A better quality of life for the employees• A sustainable future for our children.

One of the drivers for a comportemental change!

Conclusions: Benefits of Managed Green IT


Success starts from architecture … but should be enlarged

Success depends upon whole IT and I&O community:

Architecture can help to structure the effort

Our mission: sponsor/promote Green aspects in each IT domain & projects

Next step: Transforming IT Managers into IT Sustainability Managers
