Agenda

The Drivers for Sustainable IT

The challenges • How to reduce the carbon footprint and energy consumption

associated with building and running the IT estate?• How to manage the ever-increasing demand for computer systems

and its impact on the natural resources required to create them and to dispose of them?

• How to use IT to minimise wastage of other assets and resources that are used within an organisation?

• How to support the enterprise (suppliers, partners, workforce and customers) in a globalised economy, to make more efficient use of their time, resources and expertise, while minimising the impact on the environment?

Drivers for Sustainable IT

Environmental - ‘[sustainability]…relates to the protection of natural capital, including water, land, air, minerals and ecosystem services’

Encyclopaedia of Global Environmental Change, Robert Goodland, World Bank, “Sustainability: Human, Social, Economic and Environmental”, 2002

Financial – Data Centre costs spiralling year on year Broadgroup 2006: energy costs of running a corporate UK data centre is currently about

£5.3m a year, this figure is set to double to £11m over the next five years (2006)

Regulatory – EU and local government initiatives on climate change

Waste Electrical and Electronic Equipment, Climate Change Action Plans

Risk – Ability to Grow Data Centre Footprint at Current Rate while Maintaining Required Energy Levels

Desktop Efficiencies• Thin client Solid-state thin-client devices to reduce

desktop power, cooling and maintenance requirements

2 Managing the IT Lifecycle from Supply to Disposal

Maximising utilisation of IT Estate:• Virtualisation, consolidation,• Information lifecycle management

Procurement Policies• Technology and asset life-cycle• Extended life cycles – user devices from 3 > 4-5 years (dual core)• License implications on reuse / repurpose / disposal

Legislative compliance & sustainable supply chains• Waste Electrical and Electronic Equipment (WEEE) Directive• Restriction of Hazardous Substances (RoHS) Regulations

PVC and BFR strategy, and product content• Sustainable (fair and safe) supply-chains

Auditable ‘take-back’, remanufacture, recycling, charitable reuse• Disposal as last resort – hard-disk ‘scrubbing’ vs destruction (data protection)• Consumables – cartridges, paper-type, batteries, cables• Minimised packaging and removal

3 Using IT to preserve other assets

Using RF-ID Tags and Real-time location systems to track assets e.g. pallets, containers, and reduce waste

Using remote monitoring, control and calibration systems e.g. monitoring vibration levels in oil tankers, condition of underground pipelines

Reducing paper consumption through collaboration systems, and scanning technologies

4 Supporting globalisationwhile minimising travel

Telepresence: reducing travel through full size videoconferencing

Collaboration systems: document collaboration, “smart boards”, Web 2.0 and 3.0

Virtual worlds for collaboration

Summary

A Sustainable IT strategy must be incorporated into a Corporate Social Responsibility programme and have board-level sponsorship

It should address a range of possibilities, not just carbon emissions, including:

• Energy consumption and Data Centre footprint• Managing the IT Lifecycle from Supply to Disposal• Using IT to effectively manage other assets• Supporting globalisation while minimising travel
