Investigating the potential for Negative Emissions Technologies (NETs) in Ireland

Most climate change mitigation scenarios analysed to date by the Intergovernmental Panel on Climate Change (IPCC), for efforts consistent with the goals of the Paris Agreement (keeping global average temperature rise well below 2°C over pre-industrial), rely on presumed deployment of so-called “negative emissions technologies” (NETs) at very large (global) scales within a small number of decades. 
Negative emission technologies are composite technology systems which achieve net removal of one or more greenhouse gases from the atmosphere. Example NET concepts include Afforestation/Reforestation, Bio-Energy with Carbon Capture and Storage, Direct Air Capture of carbon dioxide, and enhanced soil carbon storage.

ie-nets is a two year research project, funded by the Irish Environmental Protection Agency of Ireland (EPA) Research Programme 2014-2020 (grant number 2016-CCRP-MS.36). The project will build Irish research capacity and contribute to effective national policy in this emerging area.

The overarching objective is to provide a detailed and rigorous assessment of the scale and speed of negative emissions technology deployment that is required by currently envisaged decarbonisation pathways (globally and nationally), consistent with the Paris agreement goals.

The project is being undertaken jointly by Dublin City University and Trinity College Dublin under the direction of Professor Barry McMullin (DCU) and Professor Mike Jones (TCD).

Our work in Trinity will focus on modelling the bioenergy resource potential in Ireland, asses the greenhouse gas impact of growing bioenergy in Ireland and asses the cost and technical consequences of achieving negative emissions in biofuel production.

Previous Projects
Ph.D Title: The quantification of population dynamics of Pinus and Ulmus in Europe during the Holocene
Disease, climate change and human activities have long term impacts on tree populations, but the longevity of trees challenges the investigation of their dynamics. This project developed models of long term tree population dynamics using pollen data. Pine and elm were selected for analysis because of their dynamic but contrasting histories in Europe over the last 10,000 years. The aims were achieved by collating data from the European Pollen Database and analyzing the spatial and temporal trends in declines and recovery of these taxa. Climate, edaphic and human impact data were considered as possible drivers. 
There will be a further focus on pine and elm in Ireland, investigating the native status of Scots Pine, exploring the growth of pine on bog surfaces in Ireland and characterizing the post-decline dynamics of Elm.

This research is funded by the Trinity Centre for Biodiversity Research.
