EPA - Ireland's Environment, An Integrated Assessment - 2020

Ireland’s Environment – An Integrated Assessment 2020 To inform the Parties on the development of low GHG emissions strategies and NDCs to 2030 the UNFCCC requested the IPCC to provide a Special Report on Global Warming of 1.5°C . This report was published in 2018 and indicated that: n to limit warming to below 2°C, global carbon dioxide emissions need to be reduced by about 20 per cent from 2010 levels by 2030, and reach net zero around 2075 (2065-2080) n to limit warming to 1.5°C, global carbon dioxide emissions need to be reduced by about 45 per cent from 2010 levels by 2030, reaching net zero around 2050 (2045-2055) n emissions of non-carbon dioxide GHGs should also be reduced but do not need to reach zero; these reductions are similar for 1.5°C and 2°C pathways n carbon dioxide removal (CDR) technologies, including removals by terrestrial sinks such as forests, are needed to offset any overshoot in carbon dioxide emissions and to offset the emissions of non-carbon dioxide GHGs, which cannot be reduced to net zero. An overview of selected international, EU and national policy objectives and targets is given in Table 2.1. 38
