The importance of non-CO₂greenhouse gases

Non-CO2 greenhouse gases: the underrepresented, complex side of the climate challenge

“…Special attention is paid to environmental targets such as the United Framework Convention on Climate Change (UNFCC), and to the UN Sustainable Development Goals (SDGs). Based on preceding editions and particularly NCGG7 (Kroeze et al 2014;Kroeze and Pulles 2015), it was concluded that there is a widely recognized essential role of non-CO 2 mitigation in reaching deep mitigation targets (limiting global warming to 2 degrees Celsius or lower), in line with recent literature (Frank et al 2018;Rogelj et al 2019;Harmsen 2019). However, it was found that this is not reflected in the attention for non-CO 2 related research and policy, compared to that of CO 2 .…”

“…The papers in this Special Issue help to address the gap of non-CO 2 GHG research identified in Kroeze et al (2014) and Kroeze and Pulles (2015). Based on the outcome of NCGG8 conference, it can be concluded that non-CO 2 GHG related research remains an important, yet relatively small field, given the fact that 1) stringent climate targets require non-CO 2 mitigation to become a key part of global climate policy (Frank et al 2018;Rogelj et al 2019) and 2) non-CO 2 related policy will need to consist of a combination of many independent solutions, even more than in the case of CO 2 emissions.…”
