Cara's Climate Friday FAQ #3: Is there a national solution to climate change for Ireland?

Welcome to Climate Friday FAQ #3! This week, I faced a difficult question that I didn’t have an immediate answer to. I’ve studied the science of climate change for over a decade, and I have no doubt about the ecological and social risks we face from pumping greenhouse gases into our finite atmosphere. However, I’m less certain about the solutions to this crisis. Solutions to climate change go beyond science and draw upon engineering, economics and policy, so I’ve decided to move outside of my comfort zone and find out: Is there a national solution to climate change for Ireland?

The problem starts with the fact that our economic prosperity is historically linked to greenhouse gas production. The industrial revolution (from 1750) was a period of radical technological change, which fuelled economic growth while simultaneously increasing the amount of greenhouse gas (GHG) in our atmosphere leading to climate change. Wealthy countries continue to base their economies on relatively cheap, carbon-intensive energy sources (e.g. coal, oil / fossil fuels). It seems futile to try to reduce GHG emissions without tackling this dependency on carbon-based energy for economic growth.


If you read the list of Ireland’s efforts to reduce our GHG emissions in my last climate FAQ, you’ll notice everything we have done to date has only slightly modified the existing system. We’ve chipped away at converting some of our carbon-based energy production to renewables, but we’re still a heavily carbon-dependent society. Our efforts to reduce emissions in transport have only pushed consumers to purchase more efficient, but still carbon-fuelled, vehicles. Our efforts to reduce GHG emissions have been constrained by our need for continued economic growth in a carbon-based economy. Without a seismic shift away from a carbon-based energy system and towards a fossil-free system, we are beating a dead horse with meagre actions that will not be enough to halt runaway climate change.

This week, Ireland’s Green Party is announcing its “Fossil Free in a generation” campaign. It’s ambitious - I love this kind of visionary thinking, and I know that this concept would transform Ireland into the clean climate leader it needs to become, not only to help solve climate change but also to remove our dependency on imported, insecure, and unsustainable fuel sources.  There will be those that doubt “Fossil Free in a generation” is possible – Is it pie-in-the-sky thinking or something that can actually be achieved in Ireland? I needed evidence to find out if this is Ireland’s solution to climate change.   



Fossil fuel – a material (e.g. coal or gas) used to provide heat or power that was formed in the geological past from organic, carbon-based materials (i.e. the remains of living organisms). Fossil fuels are non-renewable resources due to the long timescale required to produce them. The burning of fossil fuels contributes significantly to climate change through the emission of carbon dioxide. 

What does “fossil free in a generation” mean?

When I imagine a fossil-free Ireland, it’s my idea of a utopia. The benefits are extensive and well worth pursuing in their own right. Then I think about what “a generation” means: 2050 - It’s just 35 years from now. My daughter will be under 40 years old. The fossil-free Ireland I imagine seems far too different from reality to believe it could happen in my lifetime or hers. 

It sounds idyllic, but can “fossil free in a generation” really happen in Ireland?

Fossil-free power

At present, Ireland’s fuel mix for electricity generation is dominated by fossil fuels (83%), including gas (48%), coal (22%), peat (12%) and oil (1%). It may seem like an impossible task to convert 83% of fossil fuels to renewable fuels for energy production by 2050, but here’s the reality:
  • SEAI’s wind energy roadmap demonstrates that Ireland has the potential to produce enough electricity from wind to exceed domestic demand by 2030. 
  • The National Economic and Social Research Council’s 2012 report confirms that a fully decarbonised Irish energy system built on wind and other renewables can be achieved by 2050 by developing a smart grid in Ireland and integrating this into a clean EU energy system. 
  • The EU energy roadmap for 2050 calls for a nearly zero-carbon power supply by 2050 through use of existing technologies to change the way energy is both used and produced. 

Such a large transformation in our energy sector won’t be easy. It requires moving investments and subsidies away from fossil fuels and into renewable energy sources and smart grid infrastructure, but the long term benefits in lowering energy costs and improving our energy security would be worth the effort and investment. Ireland has already agreed to be part of Europe’s zero carbon electricity power system by signing the 2030 policy framework for climate and energy. However, in order for this transition to begin, decarbonisation of our energy supply needs to be a core objective of the DCENR Energy White Paper to be published in September, 2015. 


Fossil-free heat

We heat our homes and buildings in Ireland using a wide variety of fuels, including solid fuels (turf, wood, coal), oil, gas, and electricity. With the exception of renewable electricity, all these fuels are carbon-based and thus emit greenhouse gases when burned. There are a many things we could do to make the heating systems in new buildings energy efficient and fossil free (e.g. passive construction, solar/geothermal heating, and district heating systems). Our options to retrofit existing buildings for fossil-free heat are more limited, but not unachievable. When combined with energy efficiency improvements such as insulation, it is possible to install heat pumps cost-effectively so heat can be provided by a fossil-free electricity grid. This excellent article from Ireland’s Engineers Journal explains how 100% fossil-free heating is technically possible for Ireland’s new and old building stocks. 

Fossil-free transport

At first thought, the idea of a transport system independent of fossil fuels in the next 35 years seemed unrealistic to me. Our government has committed to a target of 10% of vehicles run on electricity by 2020, which they’re unlikely to achieve at present rate. Could we really create a completely fossil-free transport system in 35 years? 

In 2008, Min. Simon Coveney (then Fine Gael Energy Spokesperson) claimed that the Fianna Fail-Green Party government goal of 10% electric vehicles by 2020 was under ambitious, and stated it was “both feasible and realistic to aspire to achieve the complete replacement of petrol and diesel engine driven cars with electric vehicles within 15 years”.  I couldn’t find evidence to support Min. Coveney’s claim of being able to achieve fossil-free transport in 15 years, but recent peer-reviewed evidence for Ireland demonstrates that we could de-carbonise our transport system within 35 years by replacing 80% of our transport fleet with electric vehicles and powering heavy duty vehicles with biofuels or synthetic fuels. The EU low carbon roadmap aims to undertake a complete transition to hybrid and electric cars and fuel heavy duty vehicles with sustainable biofuels from 2025. While converting our fossil fuel based transport system into a fossil free system seemed unrealistic to me at first, it is technically possible and on its way to becoming a reality at EU level.  


Carbon-neutral agriculture

What does carbon-neutral agriculture mean?

The 2012 NESC report defined a carbon-neutral society as one where the net greenhouse gas emissions associated with activities within that society’s geographic area are zero. Teagasc extended this definition to agriculture by defining carbon-neutral agriculture as the “scenario in which national GHG emissions from agriculture are fully offset by carbon sequestration by grassland soils, forestry and other land use”. The NESC Secretariat proposed carbon-neutrality as a ‘horizon point’ for 2050 to which Irish agriculture could aspire.

Is carbon-neutral agriculture possible in Ireland?

Teagasc conducted a qualitative investigation to answer this question in their 2013 report, Carbon Neutrality as a horizon point for Irish Agriculture. They cited a host of uncertainties in future policy and market developments (e.g. price of carbon credits) and in scientific understanding (e.g. how carbon sequestration measures such as afforestation will respond to a changing future climate), all of which prohibited them from giving a definitive answer to this question.  However, nowhere in the report does it state that carbon-neutral agriculture by 2050 is impossible. 

What’s noteworthy is that the report emphasises the longer we wait to take action, the more difficult this goal of carbon-neutrality will be to achieve, and  “even with the uncertainties surrounding the policy and economic landscapes between now and 2050, an ‘early start’ on the pathway towards carbon neutrality will be required”. For example, the report cites the need for immediate action to develop a substantial forestry sink as a cost-effective mitigation measure for the future. 

The most encouraging part of the Teagasc report is their conclusion that implementing the concept of carbon neutrality in Irish agriculture “allows a significant expansion in the potential and positive contribution that agriculture can make” to reducing national GHG emissions. In their words, “full carbon-neutrality for agriculture by 2050 may be difficult to achieve, but this should not distract from efforts to approach carbon-neutrality as a horizon point.” Even aspiring toward carbon-neutrality in agriculture would make a significant difference in our country’s GHG emissions. 

Is “fossil free in a generation” Ireland’s solution to climate change?

The “fossil free” concept is not new. In 2014, Friends of the Earth called on the Irish government to make Ireland fossil fuel free, and rigorous research was published in the International journal of Sustainable Energy Planning and Management, which detailed how Ireland could transition to a 100% renewable energy system and consequently create 100,000 additional jobs without increasing the costs of energy.  As early as 2006, the Stern Review on the Economics of Climate Change emphasised the need to decouple carbon-consumption and economic growth. 

When I began this post, I was sceptical that the “fossil free in a generation” concept was a realistic solution to combat climate change in Ireland. However, when I broke it down into its components, I was surprised how easily I was able to find evidence to demonstrate that a fossil-free society is achievable. It won’t be easy, but the technology to undertake this ambitious transformation already exists and new technologies will continue to develop to expedite the process. The only thing that prevents such a large-scale transformation from happening is political will and the tendency to maintain the status quo rather than tackle long-term challenges.

Green Party critics could claim their “fossil free in a generation” call is an unsubstantiated dream, but this vision is truly possible for Ireland and would undoubtedly revolutionise our society. If we want to live in this fossil-free world and enjoy all the benefits it has to offer, we simply have to elect representatives to carry out our vision.

Keep fighting the good fight!

Inspiring post! One point worth adding (already implied in your comments about the building sector) is the potential for using less of everything. Fossil-free transport becomes much more feasible if we manage to figure out our land-use and transport planning to allow a sizeable portion of the population to choose whether or not to own a car. And our villages and towns would become much more pleasant places, destinations in their own right, in the process. All in all, a fossil-free Ireland is an inspiring vision. It would be the greatest love-letter to the next generation we could imagine. Now we just need some more people to join you in painting the picture of what it will look like.

I think this is the best of the three yet, because it is based on a real and tangible premise/question. It does, however, reinforce the 'real world' view that the difficulties in achieving a fossil fuel free country out weigh the positive factors. Not least that governments seem incapable of comparing the present and near futures with the long term and seeing the net cost/benefits of acting/not acting on this issue.

I think its easy to talk about potential green solutions. We all know green is technically feasible but frustrated politically. But the premise to all this really hopeful green talk always is that we are in a democracy, and I think that's perhaps a mistake. If we are in the shadow of an oligarchy, not a democracy, then we need to think about how to change that, rather than repeatedly voicing green hopes. If the oligarchy thinks green is only about money maybe we need to rethink strategy? For example, September 20, 2016, I y emailed Irish the Minister for Transport Tourism and Sport, Mr. Shane Ross (minister@dttas.ie), and asked him if Dublin is going to do anything at all to promote and increase city cycling and commuting, and he answered [indirectly], no. Said the level of investment proposed to support cycling in Dublin is 100 million euro, which sounds nice, but when I looked into it, I found this is a mere 1% of the Minister's planned funding, and this paltry 1% is to be spent entirely on cycle education in schools ['wear your helmet']. No new bike paths. See the Irish government's proposed Programme for Partnership Government 2016 for the delivery of Smarter Travel measures over the period of the Capital Investment Programme 2016-2021. 99% is to be spent on roads etc. I believe these are no goofs or failures to understand whats needed. Its not a lack of citizen protests or comments. Its deliberate transfer of public money [taxes, debt] into corporate [oligarchic] coffers.
