Well no, actually, I don’t think there is. But I’d like to look at one of the arguments in favour of fracking to see if there is bigger picture here that we need to take account of.
An argument often used is that fracking provides us with a short-term, interim energy source that buys us time while we develop non fossil fuel based forms of energy generation. Burning natural gas produces less carbon dioxide for the energy it provides, it is claimed, than other forms of fossil fuel so, as an interim fuel it could be a good one.
Let us put to one side all the other problems with this energy form. Forget that this could industrialise
ignore the amount of water that is needed, the transport footprint from the lorry
movements, the land needed to treat polluted water and the risk of air and
water pollution and so on.
If fracking gives us more energy for less greenhouse gas emissions then it has to be taken seriously. This sounds persuasive; it is often repeated and rarely challenged. But there are problems.
Fracking gas is methane, which does indeed produce more energy for less greenhouse gas than, for example, coal. Methane, however, is itself a very potent greenhouse gas. An often quoted figure is that methane is 25 times worse than carbon dioxide as a greenhouse gas. This, however, is a 100 year long term average, as it does not remain in the atmosphere for long. In the short term, say 20 years, methane is about 70 times worse than carbon dioxide as a greenhouse gas.
This means that you only need a small amount of gas leakage to completely negate any greenhouse gas emission advantage that burning methane has.
Whilst they have been criticised, there are some peer-reviewed studies that indicate a leakage of around 10% of methane from wells in the
. So let’s play with some figures to see just
how relevant this might be. USA
Instead of 10%, let’s be generous and say that only 2% of the methane is lost to the atmosphere. And instead of 70 times as bad as carbon dioxide let’s say it’s 50 times as bad (it makes the sums easier!). If my maths is correct this means that a 2% leakage of methane has the same greenhouse effect as the other 98% burned and emitted as carbon dioxide. In other words (and even if my maths is not spot-on) it doesn't take much leakage to make exploiting fracking gas twice as bad as it appears in terms of climate change. This could make it as bad or worse than coal and as such could not be considered an interim fuel.
Another problem with the interim fuel idea is that I've heard it before. I am old enough to remember similar arguments when
Sea oil was developed. Yes
we were talking about wind and wave energy in the 1970s and it was said that North Sea oil would buy us the time to research and
develop this properly. Ideas quickly
forgotten in the rush to develop.
I am also unconvinced that an apparently lucrative gas supply will be abandoned before it is fully exploited as renewable energy sources are developed. It is far more likely that, as with
oil, attention will turn away from any thoughts on long-term sustainability and
focus entirely on the apparent benefits of apparently cheap energy.
There are now highly emotive arguments being presented by the pro-fracking lobby: from dire warnings of the lights going out, to unchallenged claims that fracking will save the planet, that it is supported by the science, that it is good for the economy or that it will bring us out of recession. Perhaps the worst thing, however, is the way that fracking has taken over a far more important agenda about developing an economy that is fit for purpose, delivering real prosperity while maintaining and improving the environment on which we depend.

Following the governments welcome change of heart over the sell-off of Forestry Commissions woods, an independent panel was established to look at how the estate could be managed. The panel reported last year – a good report probably indicating the minimum of what we should expect from government if it is serious about looking after this public asset. Since then government has produced a forestry policy and now a consultation summary for a new Public Forest Estate Management Organisation (
). This is essentially government’s response to
the independent panels report. So what
is the progress? PFE MO
Unfortunately, in my view this government response falls at the first hurdle.
In its very first recommendation the independent panel called on government “to pioneer a new approach to valuing and rewarding the management, improvement and expansion of woodland ecosystems for all the benefits they provide to nature, people and the green economy”. It was clear from this that new ways of accounting for all the benefits provided by forests should be adopted. Furthermore, at the same time the National Ecosystem Assessment (NEA) and the Natural Capital Committee (NCC) were providing the tools to do this.
This “Governance Premises Summary”, however, falls back to a traditional approach of simply “maximising economic opportunities whilst maintaining public benefit” – a phrase that would not have looked out of place 50 years ago. What is written in the governance summary is old fashioned language reflecting flawed economic thinking and is a huge missed opportunity. It will mean that the Forestry Commission may just revert back to a narrow role of selling timber in the hope that a surplus can “pay” for other public benefits.
The independent panel report itself showed that whilst the cost of the Forestry Commission was about £20 million, the public benefit it produced was valued at a minimum of about £400 million. A 20 to 1 return on investment - if you actually did the sums. To ignore this is like a business ignoring its income stream and then being surprised when the books don’t balance!
The governance summary appears to have been written as though the NEA and the NCC did not exist. Many of the ecosystem services provided by forests are quantifiable, timber production is just one. Many others are of such fundamental importance that they underpin all other values. Forestry, as with any valuation from now on, must fully account for all these services. Indeed forest management should be the natural cause célèbre for this new approach to valuation. Only by doing so will we start to properly value forests – and foresters.
The governance summary also assumes the PFE MO will be of similar size to current Public Forest Estate. What is the basis for this statement? This provides an answer without addressing the question. The public forest estate should be led by its objectives and then the size would come out of that. The question then should be “what size should the estate be in order to deliver its functions?”, rather than “it’s this big, what shall we do with it?”
I have worries about the phrase in the
statement “for the benefit of people, the economy and nature”. This implies a balance between three competing
elements which, on the contrary, should be complementary rather than
competing. This is reflected in the
overarching objective - “the sustainable management of the estate to balance
and maximise the benefits to people, nature and the economy”. This is more a bland catch-all than an
objective. In practice it is meaningless
– is it “sustainable management” (in which case what does it mean?) or
“balance” (in which case of what for what?) or “maximising” (in which
case of what?), you can’t have all three.
The Annex then gives fairly predictable, second-level objectives under economic, social and environmental. The wording and organisation of these fail to get over recent thinking on how it is ecosystems and ecosystem services that underpin everything else. Without healthy forest ecosystems there will be no economic and social benefits yet as it is ecosystems only appear in a rather confused last bullet point in the list.
In my view the overarching objective is not overarching. It starts from the perspective of “here’s the Public Forest Estate, how are we going to manage it?” An overarching objective should actually start from the perspective of “what is the purpose of the Public Forest Estate and therefore how should we manage it?”
Therefore, an overarching objective, I suggest, should read something like:
The purpose of the
Public Forest Estate is to contribute to realising the full
potential of ’s
current and future ecological network, so that it provides an enhanced level of
the full range of ecosystem services. In
particular the England Estate should
deliver those aspects of ecosystem services that are not adequately valued in
traditional economic terms and/or not as easily delivered by the private or
charitable sectors. Public
The sub-objectives in the Annex should then articulate how it will deliver high quality forest ecosystems, rich in wildlife and how is it going to deliver benefit for people. Economic objectives must then be articulated in terms of delivering benefit for people whilst maintaining and enhancing the natural capital on which it depends. It also means that any economic approach or valuation will have to rise to the challenge of saying how it has accounted for everything and how value is being provided to people. At present “economic growth” is presented as a catch-phrase without any hint on what it means, how it will be measured or how it indicates benefit to people.
The administrative structures for the PFE MO are secondary to what it is actually required to do, we do not want the ideal structure delivering the wrong things. Nevertheless, the right administrative structure should provide the capacity and legitimacy for a PFE MO to deliver public benefit. There is a fear that the independent panel’s requirement for a Charter has been weakened and that the proposed role of “Guardians”, who should be accountable to parliament, has been toned-down. One of the greatest benefits that the PFE could deliver is by providing the resource (i.e. the public land) for vibrant and diverse community and public engagement in forests. I can see no reference to this so far but maybe it will appear in later detail.
I hope I am wrong, and I hope that people engaged in this can tell me so. Maybe the bland phrase “maximising economic opportunities” does hide a far more sophisticated approach which really does mean proper accounting for all of the vital services that we get from healthy forest ecosystems. I see nothing yet to give me any confidence though.
