Forecast energy use in Australia to 2030 indicates that greenhouse gas emissions from fossil fuels will continue to increase.

Tuesday, April 27th, 2010

Last month ABARE, the Australian Bureau of Agriculture and Resource Economics released its Australian energy projections to 2029-30.

The blow dried picture of a wind turbine on the front page is unfortunately very misleading.

The projections take into account the likely effects of the Carbon Pollution Reduction Scheme (if it ever comes in), the Renewable Energy Target, and other measures designed to reduce Australia’s carbon footprint.

ABARE predicts that the amount of electricity generated in Australia will increase by nearly 50% on 2007-08 values, or a growth rate of 1.8 percent per year. That’s only just below our projected population growth rate of 2.1%.

Total energy consumption is projected to grow 35% (1.4% a year). Its expected that in 2029-30 coal and oil will still be supplying the bulk of Australia’s energy needs. Renewable energy is expected to supply just 8% of total energy in 2029-30.

Assuming that the emissions factors for coal, oil and natural gas are similar to what they are today (for example that 1 GJ of black coal still produces around 88.43 kg of GHG when combusted), a quick calculation shows that Australia’s greenhouse gas emissions from the use of fossil fuels are likely to be 21% higher in 2029-30 than they were in 2007-08.

The table below shows the maths, using the data in the ABARE report and emissions factors from the Department of Climate Change website.

Fossil fuel 2007-08 Consumption (PJ) 2029-30 Consumption (PJ) Emissions factor (kg CO2-e/GJ) 2007-08 GHG (Mt CO2-e) 2029-30 GHG (Mt CO2-e)












Oil (assumed to be crude oil)






Gas (assumed to be unprocessed natural gas)






TOTAL       398 483

I find this data deeply disturbing – it appears as though emissions from fossil fuels will increase from 398 million tonnes to 483 million tonnes. Climate change scientists say we need to reduce emissions. Yet Australia’s emissions from the use of fossil fuels appear to be set to increase, with measures such as the CPRS appearing tokenistic.

Which begs the questions, if the CPRS is supposed to reduce emissions by 5% by 2020, how come my calculations show that our emissions from the use of fossil fuels will be higher in 2030? Or is it expected that the emissions factors will lower for coal (for example via “clean coal” technologies)? Or will the emissions reduction come from international carbon trading? As a developed country with one of the highest per capita emissions in the world is this really the best we can do?

Energy conservation (choosing to waste less energy) and energy efficiency (using less energy to achieve the same outcome) have the potential to decrease our energy use if widely uptaken. The climate change science demands a step change in our ability to save energy if we are to avoid ABARE’s disturbing projections.

Its nice to consulted on voluntary carbon abatement

Thursday, June 25th, 2009

Yesterday I attended the public consultation in Melbourne about accounting for and measuring voluntary greenhouse gas savings. The consultation was run by the Offsets Policy Team from the Department of Climate Change.  

It was good to be consulted and heard, and made me feel a little less disenfranchised by the CPRS.

Four or five years ago I attended a number of state government consultations on climate change. There was always strong disagreement and a lack of consensus. Yesterdays workshop was doubly satisfying for not only feeling that my opinions were being heard, but to also see that pretty well everyone else who attended was expressing the same view point. Many individuals and small businesses want to make a contribution to reducing greenhouse gas emissions. And we want our contribution to be a real, recognizable contribution that actually reduces carbon emissions and is additional to that which would be achieved by the CPRS.

It was reassuring to be able to ask questions like “what is the definition of a small business under the CPRS” and learn that this same question had been asked in similar workshops around the country.

Hopefully the workshops will help the government make changes such that voluntary carbon ababement by businesses and organisations not liable under the CPRS is recognised. In a way that the business doesn’t have to “pay twice” to get their carbon abatement recognised. And that withdraws the carbon voluntarily saved from the CPRS.

Get a solar system for FREE – but only in the next couple of weeks – and don’t think its going to save the planet!

Thursday, May 21st, 2009

The federal government’s $8,000 rebate to householders installing a PV system runs out on 30 June. Time is running out if you want to take advantage of the rebate, which you are eligible for you if you own a home and your household income is less than $100,000 a year.

If you do an internet search or scan the papers you can find at least two companies offering a 1kW grid connect solar system for free, excluding the metering. You have to assign the installer the RECS (Renewable Energy Certificates) to get the system at this price, and may have to pay extra for variations to a standard install such as fitting it to a tiled roof. Considering the historical price of PV systems, the free offer is very good indeed. If you don’t already have a PV system – consider getting one now – but you should be quick, some of the free offers are expiring at the end of May or early in June.

The PV system on your roof will cut your power bills by about $200 a year for a 1 kW system, and should add value to your house. Lets say all up your costs including the meter install are say $1,000. That’s a 20% return on investment, which is pretty good.

By assigning the RECS to the system installer, and if the government’s proposed Carbon Pollution Reduction Scheme (CPRS) legislation goes through, don’t kid yourself that you are saving the planet by putting on the PV system. The clean energy provided by your PV system is assigned to the system installer when you give the installer the right to the RECS, and the carbon savings arising from the system essentially won’t count under the proposed CPRS.

So look at it as a chance to cut your bills, improve your property value, and make it look as though you are doing something to save the planet, although unfortunately under the proposed CPRS you won’t be. Its not clear to me if you’ll be able to voluntarily “lock up” the carbon savings by making a payment to the proposed Carbon Trust – and thus actually do something to slow climate change – if you’ve assigned the RECS to the installer.

If you go ahead, be aware that the metering install can be fraught with pitfalls. Make sure you follow the advice of your electricity distribution business – see for a link to the guides offered by different distribution businesses.

And, even though you are putting in a solar system, also make sure that you are buying 100% governmetn accredited green power from your retailer. Keep you your greenpower purchases until the CPRS comes in, after which point it may not make a difference.

Budget 2009: Pay twice to cut carbon.

Wednesday, May 13th, 2009

Direct quote from the government’s 2009 budget web site:

“Households and small businesses will be able to calculate the potential dollar savings from their energy efficiency actions and make tax deductible donations to the Energy Efficiency Savings Pledge Fund. The Australian Carbon Trust will use these donations to purchase and retire Australian emissions units or purchase carbon offsets.”

What this means:

  • If you voluntarily cut your household energy consumption to save greenhouse gas – sorry the greenhouse savings don’t count! If you want to reduce greenhouse gas emissions, you have to actually now go and pay to “retire” the carbon you’ve saved – and pay the government to do so. See my earlier blog posting rantings about the disincentives in the CPRS (Carbon Pollution Reduction Scheme) for more detail. Basically if you don’t pay to retire the greenhouse gas you’ve saved, the entity generating the energy (say an electricity generator) can claim it. And trade it. And you have contributed no additional greenhouse savings beyond that which the emissions trading scheme would achieve anyway.
  • If you are a small business…. hang on… what is a “small business”? As only Australia’s top emitters get to participate in the CPRS doesn’t the definition of a “small business” in this context mean anyone who can’t participate in the CPRS? To participate in the CPRS you either have to directly generate over 25,000 tonnes of carbon a year, or consume more than 100 Terajoules of energy. In other words you are a small business if your annual energy consumption is less than 100 TeraJoules of energy or you directly produce less than 25,000 tonnes of carbon. What is a tera joule? You are probably familiar with kilojoules (1,000 joules), a tera joule is actually 1,000,0000,000,000 Joules. 100 TJ equates to an annual energy expense of about $2 million (as does the production of 25,000 tonnes). So, if you spend less than around $2 million a year on energy you are a “small business”!

So let me rewrite what budget actually means in plain English. “If you spend less than around $2,000,000 a year on energy, and you cut your energy use, in order to be able to also say that you’ve cut Australia’s greenhouse gas emissions you need to pay the government for it to recognise that what you’ve saved is an actual saving.”

Or, lets do a hypothetical here. Lets assume that you are a “small business” – ie your energy expense is less than $2 million a year. (What a tiny, wee business you’ve got if you’re not spending $2 million a year on energy!) You invest $10,000 in upgrading your lighting (using Mirrorlux Reflectors say). This saves you  $5000 a year on your electricity bills and about 25 tonnes of carbon annually. But if you want to say that your investment has reduced Australia’s emissions you actually have to pay. Lets say the carbon price settles at $50 a tonne. You’ll have to spend $1,250 a year to be able to genuinely say that your investment in your lighting upgrade is saving greenhouse gas. Because if you don’t, under the CPRS, the electricity generator supplying you the power that energises your lights has the right to the carbon you’ve saved.

Another hypothetical. This time you invest in a new gas heating system in your school. You spend $300,000 to put in gas space heaters and eliminate the old central heating system. It saves you approximately $20,000 a year in gas costs, and about 160 tonnes of greenhouse gas emissions a year. At $50 a tonne you have to pay the government $8,000 to “retire” the carbon you’ve saved. 40% of the financial savings you’ve realised goes to the government if you want to be able to say that your investment is actually reducing greenhouse gas emissions.

Are, you, like me, someone who believes that personal or “small business” action can do something to avert dangerous climate change? Do you, like me, spend less than TWO MILLION DOLLARS a year on energy? Well the government is clearly telling you and me that if we want to make a difference we have to pay twice. Pay for the investment to cut your emissions. And then pay the government to retire those emissions.

Isn’t there something really really wrong if we have to spend twice to cut our greenhouse gas emissions?

Forget the CPRS – its up to you

This blog aims to show how acting vigorously to reduce carbon emissions is good for the environment and good for business. That it is possible to create a “win-win” with the right approach. The Emissions Trading Scheme – officially known as the Carbon Pollution Reduction Scheme (CPRS) clearly, as explained in earlier blog posts, is climate negative - its not good for the environment.  

Various blogs today responding to the release of the draft CPRS legislation by Climate Change Minister Penny Wong point out that its not just bad for the environment – it goes so far in its compensation to major emittors that its actually good for big business. refer to a study commissioned by the Australian Conservation Foundation which shows that many of the major polluters will actually benefit from the CPRS as a result of the free permits handed out. The Crikey post summarises this as follows “So let’s be clear: the the Government’s rationale for amending its already-generous ETS so that it rewarded big polluters was not to prevent the loss of jobs and emissions overseas, but to ensure the profitability of big polluters.”

Paul Gilding in the Business Spectator writes “This is as good a deal as business will get. It is easy to imagine a future government, when the icecaps have melted, the cyclones are hitting and the fires are burning, imposing a much tougher regime than the one currently on the table. The CPRS is a bad deal for the climate but it’s a great deal for business. Take it and run or you’ll rue the day you didn’t.

So lets summarise the above. The CPRS is bad for the climate, but good for big business. Its lose-win legislation – a loss for the environment and a win for those businesses that are major pollutors. In the short term anyway its a win for the major polluters, but in the long run won’t be - big business managers and shareholders won’t be immune to the effects of dangerous climate change.

Which brings me back to the argument that those of us who want to be climate positive need to be coming up with ways of reducing carbon pollution that are also great for the hip-pocket - in the short to medium term and not just in the long term. With products and services that business willingly buy because its good for the bottom line as well as being good for the environment. And that we need to be making the CPRS irrelevant – by making it so easy to be sustainable that its foolish not to. We have clarity now that the CPRS won’t cut emissions, and may actually put a floor on the amount of emissions reduction that can be achieved. Hopefully this flaw will be removed over the next few months as the legislation is debated. But we have a heck of of an innovation and entrepreneurial challenge!

And there is also a tremendous social challenge – the challenge of changing society to the point where carbon pollution becomes abhorrent and morally repugnant – for most of us.

If you care about future climate stability I’d encourage you to act as a carbon-saving innovator or entrepreneur, or to influence to create a society that is carbon-intolerant, and not put too much faith in the CPRS.
