Progress in the way of Geo-engineering?


As I mentioned in the opening post of my blog the IPCC recently published their Fifth Assessment Report. I bring this report up again because something interesting was included in it – a paragraph on geo-engineering, well climate engineering, featured for the first time! It goes as follows ... 

IPCC 5th Assessment Report
Methods that aim to deliberately alter the climate
system to counter climate change, termed geoengineering,
have been proposed.  Limited evidence precludes a
comprehensive quantitative assessment of both
Solar Radiation Management (SRM) and Carbon Dioxide
Removal (CDR) and their impact on the climate system.  
CDR methods have biogeochemical and technological
limitations to their potential on a global scale.  
There is insufficient knowledge to quantify how much
CO2 emissions could be partially offset by CDR on a
century timescale.  Modelling indicates that SRM methods, 
if realizable, have the potential to substantially offset a
global temperature rise, but they would also modify 
the global water cycle, and would not reduce ocean 
acidification.  If SRM were terminated for any reason, 
there is high confidence that global surface temperatures 
would rise very rapidly to values consistent with the 
greenhouse gas forcing.CDR and SRM methods carry
side effects and long-term consequences on a global scale. 
(p. 21)

I don't know about you, but I think I agree with many others in thinking that the paragraph on climate engineering is neither in support nor does it entirely dismiss climate engineering. Despite this, however, a backlash has occurred in response to it from those, such as the ETC group, who are opposed to legitimizing ‘geo-engineering’. 

Ocean Fertilization in the eyes of the ETC

This backlash has occurred because in the eyes of some this inclusion of geo-engineering gives it legitimacy regardless of how 'layered with caveats it is' (Stilgoe, 2013). To date, proposals on geo-engineering have attracted controversy (Parson and Keith, 2013) and so this response is, I suppose, unsurprising. 

It does, however, prompt an interesting question of what the IPCC's inclusion of climate engineering will mean for the future addressing of climate change? More specifically, what will this mean for the contributions of Working Group III (WGIII) on climate mitigation that are to be published in April 2014. Are we witnessing a first step towards an acceptance of climate change methods?


#FirstStep

More realistically, perhaps, is the assertion that perhaps the IPCC have recognised that at some point we might need to use geo-engineering to mitigate climate change. 

As things stand, however, geo-engineering is in need of more research and development. In turn, this means competent and legitimate governance is required however there is currently no governance that exists beyond scientific review or national laws - meaning geo-engineering doesn't have any international legal control (Parson and Ernst, 2013). 

Recognising this as a void, guidelines, on the governance of geo-engineering research, have been proposed by the Solar Radiation Management Governance Initiative and Oxford Geo-engineering Programme. Their attempts to aid geo-engineering progress are however hindered as their proposals lack the specificity needed to aid operational governance and they fail to address key questions such as how the boundary between small and large scale geo-engineering should be defined and what level of regulation - science or government - is needed?  

Questions such as these are central to geo-engineering debates as they serve to polarise people, creating tensions as a result of geo-engineering's dual prospect as an activity that can involve large risk reduction and formation (Parson and Keith, 2013). 

A battle thus exists between those opposed and those in favour of geo-engineering. Those opposed to geo-engineering point out the environmental risks that are associated with it and the difficulties of having strict control over methods due to the broad categories used. Adding fuel to the fire of skeptics are also failed attempts of geo-engineering such as the ocean fertilisation project in Canada (Nature, 2012).

Where does this leave us then ...  
Currently, progress is being made through the use of climate study methods such as natural and anthropogenic analogs, climate modeling, field experiments and small scale tests to explore the use of geo-engineering (Robock and Kravitz, 2013). 

But it is also being limited by the deadlocked geo-engineering debate. At this stage, I can't help but agree with Parson and Keith (2013) when they point out that geo-engineering might actually be needed in the future and if research is blocked now, if we need to use it in the future we will be left with under-researched and risky methods. For this reason, I restate the four aims they advance for the progress of future research governance (see below) as they concurrently highlight the areas that hinder geo-engineering progress and highlight ways to facilitate it.  


1. To let low risk, scientifically valuable research proceed 

2. To give scientists guidance on the design of socially acceptable research 

3. To address legitimate public concern about reckless interventions or a thoughtless slide from small research to planetary manipulation

4. To end the current legal void that facilitates rogue projects

Progress - What Progress?

With regards to renewable energy and geo-engineering little has been done in the way of progress - by that I mean the implementation of geo-engineering and renewable energy methods in order to address environmental change. For this reason I am going to have a look at the progress of both renewable energy and geo-engineering in my next two posts ... 

In the United Kingdom during August 2011 The Energy Bill was formulated with the purpose of addressing three main objectives: to tackle barriers to investments in energy efficiency, to improve energy security and to enable investment in low carbon energy supplies.




Regarding renewable energy there are five policies in the Act which are relevant - 
the Green Deal, a Feed-in Tariff (FIT), Renewable Heat Incentive (RHI), Renewables Obligation (RO) and an Electricity Market Reform (EMR).

Looking at these in a little more detail ...

The Green Deal is a new financing framework designed to enable the provision of fixed improvements to the energy efficiency of homes and businesses. It’s funded through an added charge on energy bills to avoid the need for upfront costs for consumers. Alongside double-glazing and insulation improvements, renewable energy generation is also proposed as an energy saving improvement. The Green Deal can be combined with other schemes such as the Energy Company Obligation, Feed-in Tariffs, Renewable Heat Incentive or the Renewable Heat Premium Payment to make improvements more affordable.

The Feed-in Tariffs (FITs) scheme was first introduced in 2010 with the aim of encouraging the use of small-scale renewable energy generation by offering financial incentives for each kWh generated.
The FITs cover technologies such as solar photovoltaics (PV), hydro, anaerobic digestion (AD) and wind and domestic scale microCHP and people using these will receive payments from an electricity supplier of their choice for the electricity they generate, use and also for any surplus electricity. 

The Renewable Heat Incentive (RHI) is also a tariff scheme payable to energy users generating their own renewable heat. The scheme is targeted at businesses, the public sector and non-profit organizations – bigger users of energy – and aims to help them meet the costs of installing renewable heat technologies. The range of technologies the scheme supports include biomass, ground and water source heat pumps, geothermal heat, biomethane and biogas and solar thermal collectors. 

The Renewables Obligations (RO) is the main mechanism in supporting the generation of large-scale renewable electricity. It entails placing an obligation on licensed electricity suppliers to source a specified proportion of their electricity from renewable sources and if they don’t they are penalized. Renewable electricity suppliers receive Renewable Obligation Certificates (ROCs) for every MWh they produce with the number of ROCs per MWh varying depending upon the technologies used.

Electricity Market Reform (EMR) can be first evidenced in the publication ‘Planning Our Electric Future: A White Paper for Secure, Affordable and Low-carbon Electricity’ as the paper sets out to achieve the ‘government’s objectives on decarbonisation, renewable energy, security of supply and affordability.

Policies that promote renewable energy such as those outlined above from the UK are all good and well if they are causing positive changes. But this doesn't seem to be the case, well not in the UK as responses to a recent poll shows 'Energy-saving attitudes unchanged by green deal and price rises'. It was asserted that the Green Deal would increase energy efficency in the UK however since its 2011 launch only 57 deals have been completed and despite there being a popular concern over increasing energy bills few are aware of the solutions that can be found in being more energy efficient. 

This eye-opening response leaves one questioning whether there is much point in these policies being in place and worse still it highlights the 'government's failure to develop a functioning energy efficiency policy' (Platt, IPPR). For progress to be made then perhaps the area it needs to occur in is not in the technologies themselves but rather in the government efforts to bring awareness to renewable energy and encourage its use. That said, to see whether this conclusion holds, the viability of renewable energy technologies is a task that must, and will, also be done. 

Before this though I will look a little into the progress of Geo-engineering in my next post. So, until next time enjoy reading!
