Carbon Offsetting not possible in the UK – is this correct?

Noticed this on the SD Commissions website today –

… However, it is not currently possible to do carbon offsetting in the UK, as this would lead to the double-counting of any reduction in emissions (as all reductions are already claimed by Government in helping to meet our international obligations)…

Is this correct?  This needs to be read in the context of the SD Commission’s view on Carbon Offsetting and Neutrality, but having read the web page a few times I assume this means that the offset projects cannot be UK based?

So planting trees in Scotland or anywhere else in the UK, to absorb/sequester carbon dioxide, or any of the other main greenhouse gases is not available to construction projects looking to offset.  Well there go a few I know off…

Anyone care to clarify or offer an explanation of this?

Contraction and Convergence – UK Gov response

I recently participated in an online petition to 10 Downing St on the governments response to C and C.  The response here is well worth a read, covering C and C and personal; carbon trading, the climate bill and other carbon iniatives.

Cant help thinking there is some political greenwashing here.

Incidentally the petition was organised through Facebook and blogs – demonstrating the emerging recognition and influence these new social networks have.

Construction carbon calculator – no more excuses…

As mentioned before the topic with the highest hits and searches here on isite is a carbon calculator for the construction process.

I have been reviewing the calculator from the Environment Agency which come close, very close, to removing any excuses for not knowing the construction process carbon footprint, in setting a stake in the ground as a measure for improvement and in benchmarking across sites, companies and clients to drive real improvement.

In my opinion the positive points are:

  • written by a major client of the built environment for the built environment
  • not linked to carbon offset programmes (a big tick !)
  • based on spreadsheet (Excel) with visibility of data used in calculation.
  • appears easy to use with guidance, references and further reading
  • ‘open source’ in that the EA encourage its use by others
  • provides a great basis for carbon footprint benchmarking (watch this space!)
  • ability to add activities and materials to the base set up
  • deals with personal transport in a sensible and straightforward manner

The only (very) minor concern is the detail required to complete fully ( but then who said carbon diets were easy! and it would be good to see this tool as part of all site processes) and the materials element could be double counted – in the construction process footprint and the building footprint.

The EA will use the calculator on all of their projects from November

Built Environment and GEO 4, the last wake up call?

In 1987 (sustainable development) was about meeting the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland) but now in 2007 – the bill we hand our children may prove impossible to pay (Steiner UNEP)

The GEO4 report, Global Environment Outlook: Environment for Development launched yesterday by the UNEP (United Nations Environmental Programe ) should be read and considered in the context of the contribution that the global built environment has made to our current environmental crisis. (Just under 50% of global carbon emissions, 50% of all UK waste etc, etc- the figures, although varied, have been well documented in many places)

The GEO4 report received much news coverage and hopefully will be the last wake up call we need, and seen as another key milestone in our awareness of what we are doing, along side the Brundtland commision, the Stern Report, Inconvenient Truth etc

From GEO4

“all too often [the response] has been slow and at a pace and scale that fails to respond to or recognise the magnitude of the challenges facing the people and the environment of the planet,” said the environment programme’s executive director Achim Steiner.

“The systematic destruction of the Earth’s natural and nature-based resources has reached a point where the economic viability of economies is being challenged – and where the bill we hand to our children may prove impossible to pay,”

The report said irreversible damage to the world’s climate will be likely unless greenhouse gas emissions drop to below 50% of their 1990 levels before 2050. To reach this level, the richer countries must cut emissions by 60% to 80% by 2050 and developing countries must also make significant reductions, it says.

(see Contraction and Convergence)

The 550-page report took five years to prepare. It was researched and drafted by almost 400 scientists, whose findings were peer-reviewed by 1,000 others.

One of the report’s authors, Joseph Alcamo said that race is on to determine if leaders move fast enough to save the planet. “The question for me, for us perhaps, is whether we’re going to make it to a more slowly changing world or whether we’re going to hit a brick wall in the Earth’s system first,” he said.

“Personally, I think this could be one of the most important races that humanity will ever run.”

Green Schools

green school /grEn skül / n. a school building or facility that creates a healthy environment that is conducive to learning while saving energy, resources and money

To help educate and encourage construction firms and others about the benefits of sustainable schools the US Green Building Council have recently launched a site dedicated to Green Schools  According to the site, green schools, on average, save $100,000 a year, use 33% less energy, and reduce solid waste by 74%. They also increase learning potential, reduce teacher absenteeism and turnover, and provide opportunities for hands-on learning.

The site contains a number of resources, but listening to the 9min video of students talking about environmnetal stewardship as a result of their green building is very strong.  “the new building had no new smells – which is good because those smells are only chemicals” 

With criticism of the green aspects of our Building Schools for the Future it would be good to hear of similar ‘awareness‘ resources in the UK.

Carbon neutral or zero – defined?

Another excellent report from the Centre for Integrated Sustainability Analysis, Carbon Sense and Sensibility offers a definition of carbon neutral by looking at 11 websites that offer carbon neutrality calculators and services (offsets).

The definition is based around the idea of concept of measuring a carbon footprint and then seeking to cancel out that footprints with some kind of equal but opposite behaviour or consequence.

A must read for any organisation considering offsets to achieve neutrality or any carbon offset

.. you need to ask questions about just what carbon you are responsible for, how it is being measured and then exactly where the carbon credits have come from, how reductions have been verified and how you will know that once you have paid for those reductions they are retired so that nobody else can buy them …

gulp…

This then is very different from zero carbon -where activities are not neutralised but reduced to zero through ‘improvement’ activities and just doing things differently, and certainly not through offsetting.   (and the Code for Sustainable Homes calls for Zero Carbon – not carbon neutral ?)

A zero energy building (ZEB) or net zero energy building is a general term applied to a building with a net energy consumption of zero over a typical year.In October 2007, The Uk Green Building Council warned that few zero carbon homes were actually being built as as the criteria for carbon neutral stamp relief was so stringent. However, although “It’s not a legal obligation that zero carbon homes are built now”, “building regulations are being increased in line with the Code for Sustainable Homes over the next nine years”

Unravelling carbon footprints in supply chains

We hear allot about supply chain management within our industry, and until recently mainly in the context of improving value, relationships, reducing costs, waste and all the nice performance improvement stuuf.

What if we add reducing the carbon or ecological footprint into the supply chain management debate.

An excellent paper from the Centre for Integrated Sustainability Analysis – Unravelling the Impacts of Supply Chains – A new Triple Bottom Line accounting approach looks at just this issue.

It also raises the fundamental question on calculating carbon footprints – we are concerned in the main, at the moment, with direct or primary emissions – ie those we, or an organisation are directly responsible for,  How about those (secondary) emissions upstream, through the supply chain activities, raw material production etc, which in the context of a construction footprint surely must be taken into account.
We have seen this exercise start and stop within other sectors. for example the large supermarket organisation – but will it only be a matter of time before a wider view on the construction carbon emissions and contribution is expected within the built environment?

Blackout Britain

Invited to this campaign through facebook. (what? … you dont have an account there?)

Blackout Britain – Lights out for the Feast of Playful Darkness, Lights out for Carbon, Lights on for Pumpkins

On a serious note, from the Campaign for Dark Skies webiste:

The amount of additional carbon dioxide pumped into the atmosphere due to inefficient UK street-lights in the last 12 months =  541,180 tonnes

neutral, zero or offset?

With the proliferation of websites and services offering to calcuate your footprint and allow you to offset, it is good to come across one site that offers a very different approach to get the offset message across.

About CheatNeutral

Cheatneutral is about offsetting infidelity. We’re the only people doing it, and Cheatneutral is a joke.

Carbon offsetting is about paying for the right to carry on emitting carbon. The Carbon offset industry sold £60 million of offsets last year, and is rapidly growing. Carbon offsetting is also a joke.

It is also very encouraging to see that the people behind Cheat Neutral support, recommend and provide links to Contraction and Convergance.  Again from their site:

  • Learn about Contraction and Convergence. C&C is a framework for agreeing a global cap on carbon emissions. We believe that to make our individual sacrifices count, we need a global framework that caps the amount of carbon emitted, creates a timeframe for reducing emissions to a safe level, and distributes carbon credits equitably. C&C satisfies all of these, and would make carbon trading fair and effective. Good resources are at  www.gci.org.uk

Coal – safe cigarettes for the built environment?

 

isite Friday comment:

Coal has certainly been in the news, in comment columns and across the blogosphere just lately, upsetting environmentalists, campaigners and activitists. Here is a round up of coal – built environment related news and comments:

The recently commenced open cast site Ffos-y-fran in South Wales has received a scathing comment from George Monbiot in his Guardian column. As Zero Champion pointed out on the SustainabilityBlog, at the coal face, the organisations behind this project, Miller Argent, appear to be acting at odds to their environmental and or CSR visions and claims:

“We are trying to deliver lower energy, greener buildings in the right locations,” says Argent on its carbon dating page. And Miller released a CSR report this Spring which stressed its attempts to reduce the environmental impacts of its projects. “Corporate social responsibility, whether in terms of staff development… sustainable development or environmental management is at the core of our thinking,” says Keith Miller, group chief executive, at the back of the report.

The Myrthyr project is hardly sustainable, and as Monbiot states in his column, damaging to the good work in reducing carbons elsewhere.

This means that the coal in Ffos-y-fran will be responsible for almost 30 million tonnes of CO2: equivalent to the annual sustainable emissions of 25 million people (sustainable emissions are the quantity the planet’s living systems can absorb).

So in other words 25 million people need to reduce their carbon footprint to a sustainable level to balance the effects of the one coal project. How, MillerArgent, is this sustainable development.? How is this in the context of the Brundtland definition going to help future generations?

Greenpeace brought the proposed new coal power station at Kingsnorth into the news by protesting at the site. The Greenpeace film Convenient Solution, receiving warm praise at political fringe events recently, demonstrates the harm of coal power, and the wasted heat from the production:

The single biggest use of fossil fuels in the UK isn’t for electricity or for transport, but for creating heat to warm our buildings and power our industrial processes. So any solution to climate change needs to contribute to heating, as well as to electricity generation.

Only a week or so ago the American Acrtitetcure 2030 group placed a full page advert in the New York Times warning against the impact coal fired power stations will have on environmnetal, sustainability and carbon reducing actions, making the connection between coal and the built environment:

Buildings use 76% of all the electrical energy produced at coal plants. Buildings are the single largest contributor to global warming, accounting for almost half (48%) of total annual US energy consumption and CO2 emissions.

Wal-Mart is investing a half billion dollars to reduce the energy consumption and CO2 emissions of their existing buildings by 20% over the next seven years. The CO2 emissions from only one medium-sized coal-fired power plant, in just one month of operation each year, would negate this entire effort.

Over in Australia, the increasingly influential Australian Institute – ‘Clean coal’ and other greenhouse myths paper, availble from the UK Government policy hub website, busts the myths of coal:

Myth: Coal can be part of the solution.Busted: In reality, coal is the main problem, and curtailing its use is essential. There is no such thing as ‘clean coal’ at present, and there is a chance there will never be. There is no such thing as ‘clean coal’ for climate change. The description is a marketing triumph for the coal industry, like ‘safe cigarettes’ for the tobacco industry.

As many seek to achieve carbon reduction to neutral or zero through carbon offsetting, it appears the coal industry is pining hopes on the concept of carbon capture and storage, or carbon sequestration. This gives enough confidence for npower, as reported in the Guardian “coal continues to be an important source of energy for the UK and whilst this is the case, we believe CO2 capture and storage offers significant potential.”

The balancing, myth busting response from Oz?

Myth:Carbon sequestration can be the centerpiece of policy.Busted: This technology is unproven and expensive. There are several demonstration projects under way, but there is no immediate prospect of commercialisation.

So why is this important to everyday life in the built environment?

Well, coal illustrates just how very complex sustainability and carbon issue is, being personal, local, regional, national and global. The built environment demands the greater proportion of power from coal fired power stations.

The cement industry manufacturing process depends on burning vast amounts of cheap coal and contributes 5% of all global emmissions (It also relies on the decomposition of limestone, a chemical change which frees carbon dioxide as a byproduct.) So as demand for cement grows, for sewers, schools and hospitals as well as for luxury hotels and car parks, so will greenhouse gas emissions. Cement plants and factories across the world are projected to churn out almost 5bn tonnes of carbon dioxide annually by 2050 – 20 times as much as the government has pledged the entire UK will produce by that time. And like aviation the expected rapid growth in cement production is at severe odds with calls to cut carbon emissions to tackle global warming. (source, Guardian today Cement Industry comes clean)

Real reductions (not off-set reductions) in the design, construction and use of buildings will greatly reduce this demand. (This is one of the more important reasons why off-setting is bad for the built environment)

Whilst the everyday efforts on sites, in design, during construction and in existing facilities to reduce carbon and ecological impacts are so very vital, so is the awareness of the inter connections between so many of the wider social political, industrial and technological activities.

And of course there is something about the built environments claims and sustainability policies being watched by the media, pressure groups and bloggers, and all the publicity that may generate. Increasingly there are calls for some kind of watch dog to verify green claims, along the lines of the advertising standards commission, preventing misleading greenwash (a term that is used to describe the actions of a company, government, or other organisation which advertises positive environmental practices while acting in the opposite way (wikipedia)). At least no giraffes have been harmed so far…
