  • Norway Backs Carbon Capture and Storage (CCS): Will others follow? In discussing carbon capture and storage (CCS) technology deployment we ended our last blogpost by noting the uncertainties in scaling up to much larger flows than the roughly 1 MtCO2/yr level being achieved by the 15 industrial scale plants currently operating (two natural gas processing plants extract 7 and 8 MtCO2/yr for use in enhanced oil extraction). For companies, the business case for CCS is currently poor as it is expensive per tonne of CO₂ stored, relative to low carbon market prices, and the risks are not well understood, particularly in guaranteeing very long term CO₂ storage.  For governments, the political case is similarly difficult given public resistance to higher energy costs and civil society concerns ...

  • Challenges to CCS deployment Carbon Capture and Storage (CCS) is the process of capturing carbon dioxide (CO₂) from flue gasses when burning fossil fuels or biomass/biofuel and compressing and transporting this CO₂ and injecting it into an underground geological storage site. This technology is heavily relied upon in most scenarios to achieve a target global warming limit of “well below 2°C” over pre-industrial, recently agreed to by 141 parties in the Paris agreement. Examples of working CCS facilities can be seen in Canada, Iceland and Norway. Successful large scale deployment of CCS could increase energy security, significantly reduce negative impacts of climate change and support the economy. Further, if combined with BioEnergy (so called “BioEnergy with Carbon Capture and Storage” or ...

  • What Role for “Negative Emissions”? IE-NETs submission to the Irish Citizens’ Assembly The following is the on-line, plain-text summary of the IE-NETs Project Team submission as submitted to the Irish Citizens’ Assembly for its upcoming consideration of the question: How the State can make Ireland a Leader in Tackling Climate Change? The full submission is available to view here on our Documents page (and also from the IE-NETs resource page in  EPA SAFER-Data).How the State can make Ireland a Leader in Tackling Climate Change: What Role for “Negative Emissions”? Ireland and all nations agreed in Paris to act on “best available science” and “on the basis of equity” to urgently limit further emissions of greenhouse gases. The best available science tells us clearly that the climate ...

  • Will there be forestry offsets toward ‘carbon neutrality’ for Irish agriculture? Will there be forestry offsets toward ‘carbon neutrality’ for Irish agriculture?Carbon neutrality has come to the forefront of climate mitigation policy in Ireland, particularly following the Paris Agreement's reference that states: Article 4 In order to achieve the long-term temperature goal set out in Article 2, Parties aim to reach global peaking of greenhouse gas emissions as soon as possible, recognizing that peaking will take longer for developing country Parties, and to undertake rapid reductions thereafter in accordance with best available science, so as to achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century, on the basis of equity, and in the context of ...

  • Does Ireland need NETs? A centrepiece of Irish action on climate change is the Climate Action and Low Carbon Development Act, 2015. Under the terms of the Act, the Government is now required to prepare (and regularly update) a "National Mitigation Plan" which lays out the short, medium and long term pathway and policy actions for Ireland to "mitigate" its contribution to global climate change. In effect, this means a plan to reduce (or, better, eliminate completely) our collective emissions of greenhouse gases: especially carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). CO2 arises mainly from energy use (in electricity, transport and heating). Emissions of CH4 and N2O are primarily associated with our agricultural system ...

  • ie-nets full project proposal available online The full ie-nets project proposal, as approved for funding by the EPA  (grant award ref 2016-CCRP-MS.36, 5 December 2016) is now available on the ie-nets website. Here is a short extract, summarising the project motivation and objectives (please refer to the full proposal for the detailed reference list): Meinshausen et al. (2009) provides the key scientific foundation for inferring a fixed ["forever"] global carbon budget from a given target global temperature rise constraint. Under the Paris Agreement (UNFCCC 2015) the parties to the United Nations Framework Convention on Climate Change have endorsed a collective global goal of keeping temperature rise “well below” +2°C over pre-industrial. However, almost all IPCC scenarios for achieving this ...

  • Climate Action to meet the Paris Agreement: How fast is fast? The definition of climate action has been vague until recently. Now though, the Paris Agreement, ratified by Ireland and the EU last year, together with ever-stronger climate science, are making the reality of the challenge much clearer. National and EU climate policy can now be updated to align actions with the science and equity research relating to the Paris temperature limits. Here we take a look at what that might mean with the help of a new article in the journal Science written by a team including some very well known climate scientists:A roadmap for rapid decarbonizationBy Johan Rockström, Owen Gaffney, Joeri Rogelj, Malte Meinshausen, Nebojsa Nakicenovic, Hans Joachim SchellnhuberScience 24 Mar 2017 : 1269-1271  DOI ...
