It's hard to visualise greenhouse gas emissions, and more difficult still to conceptualise the numbers over time, across countries and against other important measures like economy and health. In the image, the bubble size is total emission plotted against economy (horizontal) and per person emissions (vertical).
Go to the Data Visualizer site, chose what you want to compare - from the left hand side menu - and then press play and watch the changes over time.
And a suggestion for the World Bank. Add future scenarios to this visualiser. It would be great to see the data map a path for contraction of total greenhouse emissions and, convergence to equivalent per person emissions, in the future.

The CMEPSP's report (3Mb pdf) highlights current well-being alongside the assessment of sustainability - whether this well-being can last over time. It's recommendations focus on changing our emphasis from measuring economic production to quality of life, equity and our well being over time and into the future.
It's not a new argument - famous examples included Bhutan's Gross National Happiness, Redefining Progress and, The New Economics Foundation. But it is a very prominent call for change.
Nicolas Sarkozy is encouraging a great revolution to economic and well being measurement. Others in France however see GDP here for a long time into the future. GDP criticisms include the non measurement of state expenditure, such as some public health and, the positive value it places on destructive economic activity.

A random sample of responses to his climate change question finds:
- 51.6% say support the ETS and/or don't sell out on your previous support for these laws
- 43.2% say no ETS and/or delay it, it's just a tax
- 2.1% say become the leader, presumably implicitly saying no to the ETS as well
- 3.2% say twitter discussion about this is silly
Joe Hockey asked this question as the opposition liberal party is pushing him to become leader. This change will overturn his previous position - and the party's decision last week - to take action on climate change by passing the Australian emissions trading legislation (ETS).
And the current leaders views? “This is not a game . . . We're talking about the future of our planet. We're talking about whether we, the Liberal Party, will want to be a credible, progressive political movement of the 21st century” 27/11/09 Malcolm Turnbull quoted in The Age.

Elinor is a groundbreaking economics win as her work covers how humans look after shared resources - we often collaborate to protect environments such as water resources and fisheries. That is humans do not inevitably act as 'economically rational' - out to maximise our profit.
It's often assumed that without outside intervention we will inevitably see a tragedy of the commons. This tragedy occurs as individuals overuse resources - e.g. the global atmosphere's ability to absorb carbon - reducing the quality of life for everyone.
In fact there are many examples where people do collaborate and can achieve far better outcomes than purely government action. The graph above is one such example. It compares the lobster catch in Maine (community driven management - red line) with fish (government management - blue line).
So what do we need for a triumph of the commons? Mark van Vugt's recipe for success is here.

The picture, left, shows Zentralplatz in Biel, Switzerland. Biel's town square has become an encounter zone mixing cars with pedestrians, removing traffic lanes and markings and often traffic lights. Traffic improves for everyone.
This is not just happening in Europe. Bendigo Australia has an ambitious program for shared space* - removing pedestrian crossings and creating an city where people prefer walking over cars.
Dr Rodney Tolley, Director Walk21 and author of the Bendigo transformation study says a study of such shared spaces finds they are incredibly safe. 'We are yet to find a death' in such spaces worldwide, he said in Adelaide today.
As a bonus car traffic is actually cut. Previously people drove between shops in the Bendigo space. Now it appears they walk. This has real economic benefits - shopping district come alive, along with more obvious community and environmental outcomes.

From Challenger astronaut to Professor of Sustainable Engineering and Technology at Delft University in the Netherlands Ockels, speaking in Adelaide after the World Solar Challenge, is a passionate solar advocate. He says 'solar is growing exponentially'. From 2007 to 2008 growth was greater than 100%.
If we continue to grow at this rate, 8 years from now solar panels will equal today's global electricity generating capacity. Sound's extraordinary? The numbers are in the table below.
|Year ||Solar Installed ||Global Total Solar |

Is it too good to miss an offer like this? Turns out we often do.
People generally try to avoid a future loss more than they try to achieve a future gain. This can occur even when the size of the financial loss or gain is similar. We know such an outcome occurs for finances and money and researchers David Hardisty and Elke Weber have just shown the same applies for environmental decision making.
In other words, if we are trying to encourage people to take action today - action that has long term benefits for themselves and the broader environment - we are likely to be far better off saying stop wasting $350 rather than the save yourself $350 message.
The UK Energy Saving Trust, despite it's name and proclaiming energy saving week rather than stop wasting money and energy this week, does have a bet both ways. Stop wasting energy and money is on it's home page. | Picture: irtsurveys.co.uk

In Korea it's hydrogen from landfill gas for hydrogen vehicles and a commercial hydrogen fuel cell that powers 3000 homes (cost comparisons here).
In a slightly different vein - but a sign of the times none the less - Apple, Nike, PG&E and Exelon quit the US Chamber of Commerce over it's climate stance. And UK Prime Minister Gordon Brown has put a size on the low-carbon sector. It is now larger than defense and aerospace combined.
Clearly there's some business and government action at these levels. For the moral imperative, Simon Longstaff of the St James Ethics Centre documents the uncomfortable similarities between climate responses and slavery, as argued in the UK Parliament in 1806!

Google's powermeter promises to show your electricity use from any internet connected device, including your mobile phone. By knowing your power use every day, rather than every three months, the aim is to give you information that helps cut wasted money on power bills.
Trouble was you had to have a smart meter and buy electricity from one of two - Florida and Germany - power companies. And, as Nicholas Stern highlights in his Climate Change review for the UK government: Behaviour is driven by a number of factors, not just financial costs and benefits (see summary). Easy access to information is a step towards such change.
The answer? The Energy Detective a monitor that sends your home's power use to the web. It's not quite all there yet however, 240 volt Australian / Europe versions are due early 2010.

The Harvard Business Review's bold statement sees that "Once and inconvenient truth, climate change is now an incontrovertible problem... Consumers are ever greener, and their support for sustainable products and practices is growing worldwide."
The Review's writers argue that: "organizations can turn sustainability into innovation’s new frontier – achieving competitive advantage and influencing economic recovery in much the same way that the breakthrough products and business models of computer companies led the way out of previous recessions."
We can think of such development in stages - for example:
- Viewing Compliance as an opportunity
- Making Value Chains Sustainable
- Designing Sustainable Products and Services
- Developing New Business Models
- Creating Next Practice Platforms

The world climate change tours are also on youtube. And try the Carbon Footprint project for maps of emissions etc. in the UK.
In Australia, the ACF's Consumption Atlas provides local information.

At the big end Wal-Mart is a leading example. Its CEO, Lee Scott, says “our goals are to be supplied 100% by renewable energy … to create zero waste … and to sell products that sustain our resources and our environment. Helping customers buy more sustainable products ... is something that I think all of us can be proud of.”
Boots in the UK ran a 2007 trial putting a carbon footprint reduction label on products. It’s now working with the UK Carbon Trust for a country wide labelling standard. At a store level it’s spent £5 million cutting energy use – expenditure that helps reduce greenhouse gas emissions and the company’s power bills. And in 2007, 99% of the UK Cooperative Pharmacy’s electricity came from green (renewable) sources.
So where’s the Gold for the Green pharmacy? Read more here.

- Reuse of all water (including stormwater, grey and black water).
- A cut to the Carbon Footprint associated with home use by 85%.
- Cutting potable water use by a factor of 10.
- Highly energy efficient households.
- Initiatives that deliver a significant cut to the Ecological Footprint associated with the homes and living in them.
- Fitting all 320 houses with 1 kW of Solar PV each.
At this site GreenMode is helping SAID Property Developments deliver a unique package. Many of the initiatives are likely to cost less, or no more, than those that would have a much greater environmental impact at a similar but conventional residential site. The initiatives are detailed here and the work shows how we can simultaneously get excellent results for the environment and economy.

Is it really that simple? Over the last year, the price of a solar panel at the factory gate has come down by nearly 50%. From a US$4.20 cents per watt to under $2 and 'still profitable' is the finding from UK's New Energy Finance company.
This positive news is however complicated by the market and global financial crisis. None the less, only a few years ago people installing solar electric power on their houses were calculating 20 to 25 year payback periods. For some the good news, according to the Boston Business Journal, is this payback is now only 5 years.

The picture shows one example – LED downlights. Costing between about AUD 10 and 20 dollars per light, the lights use 2 to 3 watts each. A normal downlight would use 50 watts.
The lights shown in the picture will pay for themselves within 6 months. After this, it’s money in the bank. In addition they should last many times longer than an ordinary 50 watt halogen downlight. This saves you or your business the time and cost of replacing ordinary bulbs.
Of course the answer to climate change is not just about light – although the International Energy Agency finds we could cut global electricity consumption by almost 10% with similar changes. Nor is it (only) about changing light bulb jokes.... But it is a great illustration of profitable and meaningful change that delivers economic and environmental carbon advantages.

Ban Ki-moon, Secretary-General of the United Nations, launched the book. He says:
Addiction is a terrible thing. It consumes and controls us, makes us deny important truths and blinds us to the consequences of our actions. Our society is in the grip of a dangerous greenhouse gas habit. The message of this book is that we are all part of the solution. Whether you are an individual, a business, an organization or a government, there are many steps you can take to reduce your climate footprint.

In the world of hard climate science, carbon pricing schemes and emissions targets you could be forgiven for thinking that human attitudes are of lesser importance. Nothing is further from the truth. For example - Nicholas Stern, ex Chief Economist of the World Bank and author of the UK government’s seminal Stern Review on the Economics of Climate Change highlights the importance of behaviour change. He emphasises:
Three elements of policy for mitigation are essential: a carbon price, technology policy, and the removal of barriers to behavioural change. Stern Review p.xxviii
Its one of the reasons I (Simon) am thrilled to win a scholarship for a Harvard, China and Australia joint climate change symposium. My excitement is not just for the event but also as it merges science with society. It recognises there is as much to be gained working with people’s attitudes, views and perspectives as with science, technology and pricing.
The humble light bulb is a great illustration. Look around you. In nearly any country you will see incandescent light bulbs or halogen down lights. As Amory Lovins puts it, each of these lights, remaining in its socket unchanged, is the same as walking past a $50 note on the pavement. But, for the last two decades while effective alternatives have been available, many people have nevertheless continued to walk past the light bulb.

The first, Samsung has just announced over 4 billion dollars of investment to green its electronics. It will cut the greenhouse gas embodied in its products by 50%. Once past the factory gate goods also use power and, Samsung says, its TVs, refrigerators and air conditioners will be the most efficient (lowest power use) products available.
Efficiency is also central to the stationary hydrogen fuel cell. The plant producing heat & electricity for 3000 homes does so by using 80% of the available energy from gas for a current cost of about AUD 0.23 per unit.
And the world's largest tidal power plant - it will deliver power at approximately half the cost of wind power. Hydrogen and tidal power plant pictures and detail are here. Cost comparisons here.

For any company there are many reasons to address climate change. Increasingly major companies will demand a supplier understands its carbon footprint. The international Carbon Disclosure Project reports this is already occurring with Cadbury, Colgate-Palmolive, Johnson & Johnson, P&G, Unilever, Vodafone (1) and Walmart (2) among the companies asking suppliers to report on carbon footprint and climate change strategies.
The Carbon Disclosure Project represents Investors with assets of $55 trillion. Its just one of the major reasons why, across the world, companies are looking to find carbon advantages.

The country is spending $38.5 billion on clean technology and environmental restoration. The Korean Presidential Committee on Green Growth says it will deliver 956,000 new green jobs. The four year package is about 2.6% of Korea's yearly gross domestic product (GDP). Funding goes to rivers, forests, clean transport and bikeways and, green homes and neighbourhoods.
At the same time this strategy is driving private investment. JP Morgan has just announced that it is raising $1 billion to invest in Korean solar, LEDs (high efficiency lighting) and green cars.

- Green roofs and walls plus light coloured hard surfaces and/or vegetation across roads – increasing amenity, cutting heat and consequently power use.
- Building energy efficiency through the use of green roofs and walls as well as solar hot water, efficient lighting and high efficiency appliances.
- The network city integrates commercial and industrial uses throughout its residential, agricultural and recreational areas. This reduces the demand for motorised private transport.
- Throughout the city food production is integrated into the street plantings, arbours, parks and gardens plus, roof spaces and walls. The net impact of creating edible landscapes is to reduce the city’s food footprint.

In the natural world, plants have evolved to follow the sun. So could we artificially mimic a sunflower and use this to point solar panels at the sun? MIT has demonstrated just such a system using a curved arch made from two different metals. Simple systems like this should be cheap and the techniques, known as biomimicry, have many applications beyond just tracking the sun.
But brining the natural world into today’s society is not just about hi tech applications. The picture illustrates living furniture, grow your own garden settings, certainly unique!

That's 50 to 100 coal fired power plants worth of electricity. On top of this solar electricity is set to expand 75 fold. Cummulatively he sees renewables providing close to 20% of China's power in 2020.
In 2008 China ranked second behind the USA for wind power growth. It's been doubling every year for the last four years. With nearly 38% of China's financial crisis stimulus package being spent on green initiatives, western countries will be challenged for clean technology development leadership.

Nobel prize winner Steven Chu, Obama's Energy Secretary, is promoting this change. Chu says just changing the colour of roofs and blacktopped freeways and streets is equivalent to taking all of the automobiles in the world of the road for eleven years.
White reflects heat and a worldwide change would help cool the world. As a bonus, light surfaces can help reduce the cost of cooling buildings which reduces emissions. However, Hashem Akbari, the lead scientist behind some of this research is careful to point out that converting to cool urban surfaces does not address the underlying problem of global warming.
These impressive numbers from white roads and roofs are not the only option. Living green roofs and walls can drop temperatures (and associated air conditioning costs) by as much as eleven degrees.

In 2008 Australia's total capacity increasing by over 50%, China doubled its total installed wind power and growth was 50% in the USA.
With this impressive growth comes an equally impressive challenge. Coal still provides over 40% of the world's power. While wind is growing at 29% a year, versus coal's 4.5%, in absolute terms coal still dominates over wind. The International Energy Agency wedges illustrate the challenge.

The government subsidy is for new solar plants that together produce a coal plant's worth of power - up to 1000MW. Abengoa Solar, a leading solar power company currently constructing solar plants worldwide, put the cost of a 300MW plant at 1.2 billion euros in 2007. In 2009, the Arizona state government announced a 200MW plant for 1 billion US dollars.
The actual cost and reliability of the power generated is as important as the government subsidy for construction costs. The U.S. National Renewable Energy Laboratory estimates, for solar plants generating power 24 hours a day by storing the sun's heat, electricity will soon cost about US 13 cents a unit.
On this scale, sun power is starting to become competitive with expected future power prices.

Recent work by Lend Lease (through Delfin Lend Lease) with the Queensland EPA and GreenMode shows how it can be done. The results, appearing in the Queensland Government's Smart and Sustainable Homes newsletter, are for 35 different homes of the types typically constructed in South East Queensland.
By implementing simple measures - such as insulation, orientation, high efficiency cooling and heating, and window shading - the Ecological Footprint of a home with people living in it is cut by a factor of five.
When construction and the physical maintenance of the house are also included, three of these sustainable homes could fit in the footprint of one 'standard' house (of the type commonly constructed in Queensland).

A new large scale solar electricity plant for Arizona, USA, shows the way forward. It will generate electricity by turning sunshine into heat and storing power overnight as molten salt.
It's also competitive and big. Using South Australia as a comparison, the plant will generate about a fifth of Adelaide's everyday basic electricity use. And the cost? In 6 years time, $115 per thousand units of electricity. That compares favourably with electricity from gas and also $120 for Adelaide power.
$120 was in the first 3 months of 2008, before any further inflation. It is also before a price on carbon pollution is introduced in Australia.

The graph, from Australian government figures, shows solar electricity installation per month.
This growth is occurring despite the Australian government imposing a means test on its rebates. The test currently limits rebate payments to households earning less than $100,000 a year. It was introduced in an effort to cool what Peter Garrett, Australia's Environment Minister, referred to as an overheated market.
In the middle of 2008, when the solar rebate means test is introduced, there is a momentary pause in growth but sales quickly expand again.
The results support reports from many in the solar industry. The industry says people on lower incomes, particularly pensioners, are willing to invest in smart green power. People will pay capital now for future savings.

Globally, nearly sixteen percent of economic stimulus expenditure goes to such green initiatives.
In Australia this figure is just over nine percent, China it's nearly thirty eight percent and in the USA it's close to twelve percent.

This is part of a clean future. It is much easier to supply clean power for economic activities that pollute less.
And there's a big future in clean business. Currently, renewable technologies drive 170,000 jobs in the German economy. By 2020 clean tech, say analysts, may be an industry rivalling or exceeding the information technology sector.
This then is the next industrial revolution - growth in clean technology and, significantly more growth in new and emerging low carbon sectors of the economy.

Thomas Friedman highlights this and the coming revolution for business, societies, countries and organisations to seek a carbon advantage.
As we transform our economy and build renewable, smart, reliable, efficient power throughout all our activities, we create jobs, social outcomes and also new norms for business. Paul Gilding recently pointed this out arguing the global financial crisis will not sideline sustainability.
Yesterday, Nick Stern author of the UK’s 2006 economic climate change report spoke of this directly to the G20 countries. The opportunity is to invest heavily in energy efficiency and green technology using stimulus funding. It’s a call that some countries have already begun to act on.
Which leads back to the Carbon Advantage - companies and organisations acting now will not just help to answer society's challenges. It also delivers real benefits for the businesses and organisations that do so.

He says the good news is that there are great returns to handling these two things together. While there are undoubted pitfalls to avoid, current circumstances are also a huge opportunity - climate change and the financial crisis are intrinsically linked. Stern says now is precisely the moment to change to a low carbon economy.

A snapshot - we have far more funding for energy programs in the US than any bill in history. The UK aims to access a £1 billion economic boost from energy. 3.9 of the 42 billion Australian financial stimulus goes to home insulation and solar hot water.
It is not just government. Recently investors, with US$ 3 trillion in assets, highlighted that climate actions can create $144 billion in savings. McKinsey, in its revised global Pathway to a Low Carbon Economy, finds the global investment required to address climate change is reasonable and "many of the opportunities would see future energy savings largely compensate for upfront investments."

Then Delhi built an underground system - on budget and three years ahead of schedule.
Now India's solar powered car is hitting the mainstream, having completed a tour. One of these solar cars travels 90kms on a charge - more than most Australian's daily commute. The tour, highlighted in the New York Times, traveled 2,100kms showcasing entrepreneurs and sustainable solutions across the country.

Using the heat, as well as generating electricity, means that far less energy is wasted. Localised schemes like this also save a substantial amount of power by avoiding transmission line losses.
Similar systems can be used for residential homes as well. There's a small demonstration in Sydney and Alan Jones has led the way for UK's Borough of Woking, near London.

On Lateline (Feb 10) John Brumby (Vic Premier) has been pointing to "the new climatic conditions in which we are operating”. He says "the climate is changing, we are seeing more extreme events... weather events".
Its an encouraging and brave recognition given the present, ongoing, human trauma that is still unfolding. It may also see us charting a different course - away from Clive Hamilton's prediction that "the major political parties will not want to acknowledge the association between global warming and the fires".
Meanwhile Time Magazine Why Global Warming may be Fueling Australia's Fires looks straight at this threat and Australian Firefighters are asking the government to "halve Australia's greenhouse gas emissions by 2020." The Age prints the full letter.
