Biogeoscience focuses on the interplay between biological activity and the chemical and physical environment of the Earth, and is critical to the mitigation of climate change if the world is to avoid ‘dangerous anthropogenic climate change’. Most countries set ambitious targets under the 2015 Paris Climate Agreement to cut emissions and limit the mean temperature rise due to below 2^oC and to try to keep the rise to no more than 1.5^oC. However, the emission gap between the pledges and the actual emission required to meet the targets is "alarmingly high". Current pledges cover only one-third of the cuts to meet the climate targets, and the current trajectory will result in a warming of at least 3^oC by 2100. To avoid 1.5^oC of warming, a carbon neutral economy coupled with ‘Negative Emission Technologies’ (to actively remove atmospheric carbon dioxide) will need to be in place. This presentation will examine the potential of biogeoscience to mitigate climate change in: i) bioenergy & carbon capture, and; ii) silicate-based minerals.

Professor Jeff Obbard was a professor at the National University of Singapore and Qatar University for more than 14 years. He also served as Vice President for Science & Technology at a joint-venture to develop biofuels. He was a recipient of the United Nations Mondialogo Engineering Award, and has been recognized as a Top 100 Global Sustainability Leader. He has published more than 100 papers in high quality journals.
