Global Average Temperature

2009 second warmest year ever

Jan, Feb Mar 2010 warmest everThis is despite a solar sun spot minimum

Climate Forecasts

MIT

> MIT report predicts median temperature forecast of 5.2°C– 11°C increase in Northern

Canada & Europe– http://globalchange.mit.edu/pub

s/abstract.php?publication_id=990

> Last Ice age average global temperature was 5-6°C cooler than today– Most of Canada & Europe was

under 2-3 km ice– With BAU we are talking about

5-6°C change in temperature in the opposite direction in less than 80 Years

Climate Change is not reversible

• Climate Change is not like acid rain or ozone destruction where environment will quickly return to normal once source of pollution is removed

• GHG emissions will stay in the atmosphere for thousands of years and continue to accumulate

• Planet will continue to warm up even if we drastically reduce emissions All we hope to achieve is

to slow down the rapid rate of climate change

Weaver et al., GRL (2007)

Climate tipping points

• USGS report finds that future climate shifts have been underestimated and warns of debilitating abrupt shift in climate that would be devastating.

• Tipping elements in the Earth's climate - National Academies of Science– “Society may be lulled into a false sense

of security by smooth projections of global change. Our synthesis of present knowledge suggests that a variety of tipping elements could reach their critical point within this century under anthropogenic climate change. “

2009-10 Canada winter 4.2C warmer than average

Urgency of Action• “We’re uncertain about the magnitude of climate change, which is

inevitable, because we’re talking about reaching levels of carbon dioxide in the atmosphere not seen in millions of years.

• You might think that this uncertainty weakens the case for action, but it actually strengthens it.

• This risk of catastrophe, rather than the details of cost-benefit calculations, makes the most powerful case for strong climate policy.

• Current projections of global warming in the absence of action are just too close to the kinds of numbers associated with doomsday scenarios. It would be irresponsible — it’s tempting to say criminally irresponsible — not to step back from what could all too easily turn out to be the edge of a cliff.”

Nobel Laureate Paul Krugman

Policy Frameworks - 1• Carbon tax e.g. Denmark

– Economists claim that this is the fairest and most easily implementable solution. – But in the case of Canada any carbon tax would imply a huge transfer of wealth from Alberta to the rest

of the country.

• Carbon Intensity e.g. Alberta– These programs are intended to reduce the amount of CO2 per unit energy. – They don’t reduce the overall growth of CO2 emissions, but just slow down the rate of growth.

• Mandated Carbon Neutrality e.g. BC. – This initiative is very popular with governments and is being looked at by many jurisdictions.– It allows governments to demonstrate a commitment to reducing CO2 without imposing any taxes or

other hardships on voters

• Energy efficiency Mechanisms e.g. UK. – The UK’s CRC Energy Efficiency Scheme (formerly known as the Carbon Reduction Commitment) is that

country’s mandatory climate change and energy saving scheme

Policy Frameworks-2• Cap and Trade e.g. European ETS

– This is the current favourite instrument being deployed by many governments around the world. – Cap and trade systems can be easily gamed and developing meaningful measurable, verifiable and enforceable

offset standards may be very tough.

• Cap and Dividend – is a relatively new concept and works on the similar principle as cap and trade except that all monies used to

purchase offsets by large emitters are paid in dividends to consumers. – The big advantage that jurisdictions with large emissions are not penalized as the money spent on offsets is

returned to the constituents in that jurisdiction. – There is currently a cap and dividend bill in the US congress. The proposed cap and trade bill in California is

also evolving along these lines.

• Cap and Reward – is a variant of cap and dividend where instead of paying cash dividends from the sale of offsets the money is

earmarked for the purchase by consumers and businesses of low carbon products and services such as ICT. – This creates a virtuous circle where the money earned by the sale of offsets is used to further promote the

reduction of CO2 emissions in a given jurisdiction.

The Global ICT Carbon Footprint isRoughly the Same as the Aviation Industry Today

www.smart2020.org

But ICT Emissions are Growing at 6% Annually!

ICT represent 8% of global electricity consumption

Projected to grow to as much as 20% of all electrical consumption in the US (http://uclue.com/index.php?xq=724)

Future Broadband- Internet alone is expected to consume 5% of all electricity http://www.ee.unimelb.edu.au/people/rst/talks/files/Tucker_Green_Plenary.pdf

The Global ICT Carbon Footprint by Subsector

from 592 Million in 2002 to More Than Four Billion in 2020

PCs Are Biggest Problem

Data Centers & Clouds Are Low Hanging Fruit

Telecom & Internet fastest growing

• Greenpeace says that the energy consumption of cloud computing in 2007 was 622.6 billion kWh, which is 1.3 times larger than reported by the Smart 2020 report.

• 50% of today’s Data Centers and major science facilities in the US will have insufficient power and cooling;*

• By 2010, half of all Data Centers will have to relocate or outsource applications to another facility.*

• Data centers will consume 12% of electricity in the US by 2020 (TV Telecom)

New UK Super computer• The Met Office has caused a storm of

controversy after it was revealed their £30million supercomputer designed to predict climate change is one of Britain's worst polluters.

• The massive machine - the UK's most powerful computer with a whopping 15 million megabytes of memory - was installed in the Met Office's headquarters in Exeter, Devon.

• Uses 1.2 megawatts of energy to run - enough to power more than 1,000 homes.Weather supercomputer used to predict

climate change is one of Britain's worst polluters

The Falsehood of Energy Efficiency• Most current approaches to reduce carbon footprint are focused on increased energy efficiency

of equipment and processes

• But growth in ICT deployment of equipment and services is outstripping any gains made in efficiency– Which is likely to accelerate as ICT is used to support abatement in other fields such as

smart homes, smart buildings, smart grids etc

• Also greater efficiency can paradoxically increase energy consumption by reducing overall cost service and therefore stimulates demand– Khazzoom-Brookes postulate (aka Jevons paradox - not to be confused with rebound effect)– In last Energy crisis in 1973 Congress passed first energy efficiency laws (CAFÉ) which

mandate minimum mileage for cars, home insulation and appliances– Net effect was to reduce cost of driving car, heating or cooling home, and electricity

required for appliances– Consumer response was to drive further, buy bigger homes and appliances

• The issue is not the amount of energy that we use, but the type of energy

Zero Carbon strategy essential

• Zero carbon strategy using renewable energy critically important if governments mandate carbon neutrality, or if there is a climate catastrophe

• With a zero carbon strategy growth in demand for ICT services will not effect GHG emissions– Anything times zero is always zero

• Wind and solar power are most likely candidates because of opportunity cost/benefit analysis especially time to deploy– Nuclear has high opportunity cost because of time to deploy– http://climateprogress.org/2008/12/14/stanford-study-part-1-wind-solar-bas

eload-easily-beat-nuclear-and-they-all-best-clean-coal/

• But renewable energy sites are usually located far from cities and electrical distribution systems are not designed to carry load– http://www.americanprogress.org/issues/2008/12/pdf/renewable_transmissi

on.pdf

• Purchasing green power locally is expensive with significant transmission line losses–Demand for green power within cities expected to grow dramatically

• ICT facilities DON’T NEED TO BE LOCATED IN CITIES–-Cooling also a major problem in cities

• But most renewable energy sites are very remote and impractical to connect to electrical grid.– Can be easily reached by an optical network– Provide independence from electrical utility and high costs in wheeling power– Savings in transmission line losses (up to 15%) alone, plus carbon offsets can pay for moving ICT facilities to renewable energy site

• ICT is only industry ideally suited to relocate to renewable energy sites– Also ideal for business continuity in event of climate catastrophe

Get off the Grid!

• Bill 44-2007 was introduced in 2007 and enacted into law in 2008. The law is known as the Greenhouse Gas Reductions Target Act.

• The Act establishes greenhouse gas emission target levels for the Province.– 2020 BC GHG will be 33% less than 2007.– 2050 BC GHG will be 80% less than 2007.

• Bill mandates that by 2010 each public sector organization must be carbon neutral.

• If a public sector organization can not achieve carbon neutrality then they are required to purchase offsets at $24/ton

MIT to build zero carbon data center in Holyoke MA

• The data center will be managed and funded by the four main partners in the facility: the Massachusetts Institute of Technology, Cisco Systems, the University of Massachusetts and EMC.

• It will be a high-performance computing environment that will help expand the research and development capabilities of the companies and schools in Holyoke– http://www.greenercomputing.com/news/2009/06/11/ci

Proposed new funding scenario for R&E networks and cost reduction for universities

• Many universities are proposing to go carbon neutral and/or mandated to reduce their energy and carbon footprint

• Purchase of high quality offsets difficult and costly– Better to find energy and carbon savings internally

• Computers, networks and data centers account for 30-50% of energy consumption on campus

• Video conferencing, eLearning, zero carbon data centers, clouds, grids collaborative cyber-infrastructure, etc should reduce energy consumption

• Most universities don’t have processes to allocate energy or CO2 costs to individual departments or researchers– Significant challenge as appropriating heating, cooling, electricity, computing and networks

costs can be very difficult

• There is no incentive for researchers or educators to adopt low energy or CO2 solutions

• Most R&E networks charge a membership fee or base fee based on size of institution, research dollars or number of students

• Instead propose to charge membership or base fee based on institution’s energy consumption– E.g. 1% of total Kwh for the past year

• R&E network agrees to provide a variety of services at no charge including• “X” miles of dedicated wavelengths• “Y” Mbps of Internet bandwidth• “Z” hours of video- conference• “W” time on a commercial compute cloud or central storage• etc

• Institution is encouraged to reduce energy consumption and there is penalty in services if they do so

Economic benefits of follow the wind/sun architectures

• Cost- and Energy-Aware Load Distribution Across Data Centers– http://www.cs.rutgers.edu/~ricardob/papers/hotpower09.pdf– Green data centers can decrease brown energy consumption by 35% by leveraging the green data

centers at only a 3% cost increase

• Cutting the Electric Bill for Internet-Scale Systems– Companies can shift computing power to a data center in a location where it’s an off-peak time of

the day and energy prices are low– Cassatt a product that dynamically shifts loads to find the cheapest energy prices– 45% maximum savings in energy costs– http://ccr.sigcomm.org/online/files/p123.pdf– http://earth2tech.com/2009/08/19/how-data-centers-can-follow-energy-prices-to-save-millions/

Free Wifi on Buses• There’s a school bus service called The Green Bus in Birmingham, UK which

operates double-decker, low-carbon emissions buses that carry over 1400 kids to school every day (saving over 2000 car journeys).

• In addition to encouraging kids to play peer-to-peer games, the access points allow the bus company to monitor where the buses are in the city in real time. Parents as well as staff can follow the progress of any bus via Google maps.

• Business bus service in San Francisco offers office on the move – free wifi, femto cell service etc

Carbon Reward Strategy for last mile infrastructure

• Provide free high speed Internet and fiber to the home with resale of electrical and gas power (ESCOs)– http://www.newamerica.net/files/HomesWithTails_wu_slater.pdf– Pilots in Cleveland, Switzerland, Ottawa, etc

• Customer pays a premium on their gas and electric bill

• Customers encouraged to save money through reduced energy consumption and reduced carbon output

• Customer NOT penalized if they reduce energy consumption– May end up paying substantially less then they do now for gas + electricity +

broadband + telephone + cable

• Network operator gets guaranteed revenue based on energy consumption rather than fickle triple play

Do your carbon inventory NOW!!

• You can not earn credits until you do an inventory and calculate baseline emissions– Online training available for IT staff at http://ghginstitute.org/

• Stern report – carbon needs to be $100 per ton

• At $100/t of CO2 the cost of GHG emission could be as much $10 - $50 million per year for university in the next decade

– A lot depends on post Copenhagen future

• Conversely university could earn $10 - $50 million per year if a university is zero carbon

– No revenue potential if university is carbon neutral

21

Final remarks

• The problem we face is NOT energy consumption, but carbon emissions

• Think carbon, not energy

• We must start addressing climate change now – not in 2050 or 2020

• 80% reduction in CO2 emissions will fundamentally change everything we do including universities and networks

• Huge potential for innovation for ICT sector because 30% of energy must come from renewable sources

A More Accurate Term is ‘Global Climatic Disruption’

This Ongoing Disruption Is:• Real Without Doubt• Mainly Caused by Humans• Already Producing Significant Harm• Growing More Rapidly Than Expected”

Earth’s Climate is Rapidly Entering a Novel RealmNot Experienced for Millions of Years

“Global Warming” Implies: • Gradual, • Uniform, • Mainly About Temperature, • and Quite Possibly Benign.

What’s Happening is: • Rapid, • Non-Uniform, • Affecting Everything About Climate, • and is Almost Entirely Harmful.

New Internet• Increasingly most connections will be local to nearest IX where user will connect to cloud,

CDN or social network– Connections to another user or computer at the edge of the cloud will be less common

• Network topologies and architectures will be driven by application and content rather than connecting users “end-to-end”

• Cyber-infrastructure and UCLP were forerunners of these development• Future wireless networks are likely to also evolve in this manner

– Don’t need an end to end network for accessing applications and content– User white space and wifi to provide data to cell phones– Next network neutrality battleground will be “last inch” – open devices and “last

tower” - • Much easier to deploy zero carbon Internet

– CDN, clouds and social network infrastructure can be built along GSN model– Users will increasingly use solar powered iPhone, iPad to access information and

applications

• Stay tuned for upcoming paper

• The EPA Mandatory Greenhouse Gas Reporting Rule (March 2009) in response to Public Law 110-161 (08 Appropriations)– 25,000 Tons or More Must Report to EPA.

• Waxman-Markey H.R. 2454 passes the House in July 2009 by a vote of 219 Ayes, 212 Nays, 3 Present– 17% CO2 Reduction by 2020.– Federal Cap and Trade System.

• Kerry-Boxer Clean Energy Jobs & American Power Act– More aggressive CO2 reduction targets then

Waxman-Markey (20% by 2020 over 2005, 80% by 2050).

– Cap and Trade becomes “Pollution Reduction & Investment”.

– NYT, 9.30: Best guess is as of September 30 there are about 45 yes votes for the legislation.

TD Bank• Has achieved 100 % carbon neutrality through mostly relocating servers

and computers from USA to Canada and purchasing RECs• Over 11,000 bank branches in USA• Intends to reduce purchase of offsets because of problem of finding high

quality offsets• Have implemented a charge back, cap and reward system, but have not

defined rewards– Managers for the time being are assigned credits to be applied in a

future cap and reward system

57

BC Government• One of the first jurisdictions to mandate carbon neutrality in public sector• Has resulted in huge boost in morale for government employees as they

are all engaged in finding solution• Plan to implement a full charge back and cap and trade system• Currently all travel and IT energy expenditures must be recorded in GHG

management database• Government expects to save between 700k- 1000K mTCO2e this year =

approx $25 million in savings• Additional savings in energy and travel

58

Huge jump in carbon footprint from telecom and Internet

• Huge jump in carbon footprint from telecom and Internet http://bit.ly/4MVcET

• About 37 percent of the carbon footprint of the entire information and communication technology sector (ICT) in 2007 was due to the energy consumption of telecom infrastructure and devices, according to the Climate Group (14 percent came from data centers, and 49 percent came from PCs and peripherals).

• Contrast that with telecom’s carbon footprint figure in 2002 which was 28 percent of ICT’s carbon footprint.

59

Cisco Europe• Ultimate aim is to create carbon dashboard for each employee showing

their instantaneous carbon emissions• Currently have a carbon scorecard for each country and major

department in Europe– Managers are measured against both financial and carbon budgets

• Strategy is to represent a tonne of carbon in more easier understood terms such as liters of gasoline, flight numbers etc

• Biggest savings are from travel avoidance and energy reduction as opposed to CO2 reduction

• Planning to implement a cap and reward system in the near future

60

US Government• President Obama's Executive Order 13514 the Federal Government is pursuing at

least a 20% reduction in green house gas emissions by 2020. • Federal CIO Council and agency CIOs may take on the challenge of reducing the

impact of agency computing equipment, but so far there has been no concrete progress .

• Most significant government efforts have revolved around consolidated data centers.– The electricity costs for servers and data centers for the US government has grown $450 million in

2006, and it apparently is doubling every five years. That means the cost of the electricity for the federal government’s data centers could, in theory, be $900 million next year. A 1998 survey of federal agencies identified 432 agency data centers.

• The US government is beginning the largest data center consolidation in history, hoping to dramatically reduce IT operations that are currently distributed among more than 1,100 data centers.

•

61

Analysis• Most green programs are in their infancy – lots of experimentation• Most organizations are moving away from purchasing external carbon offsets to establishing internal

markets– Finding high quality external offsets is extremely difficult

• Most companies are achieving carbon neutrality through purchase of RECs and internal savings– Most organizations are looking to energy consumption, travel and IT as the primary ways to

reduce CO2• Most organizations are starting to implement charge back mechanisms and allocate carbon & energy

costs to individual departments• Major challenges is that facilities people (heat and lighting) are largely responsible for most energy

consumption and there is no tools to allocate per department– Often building management is contracted to 3rd parties e.g. Federal government uses SNC –

Lavalin– Third party management may, or may not have incentive to reduce energy

• Most IT costs are buried within overall electrical consumption and difficult to extract separately• Cap and reward systems and Green IT are just starting to be explored

– Hindered by lack of quantitative information on energy & carbon savings of different strategies
