1 November 2018, Carbon Brief, Negative emissions: Scientists meet in Australia to discuss removing CO2 from air. An international group of researchers and policymakers met in Australia’s capital this week for the country’s first major conference dedicated to the topic of “negative emissions”. The two-day event, held at the Australian Academy of Science’s Shine Dome in Canberra, played host to a range of ideas for removing CO2 from the atmosphere and storing it on land, underground or in the oceans. The topics discussed ranged from “natural” solutions, such as boosting the carbon stores of soils and giant kelp forests, to the more experimental, including “fertilising” the world’s oceans. Carbon Brief was at the conference, which was organised by researchers from Australian National University and the University of Tasmania, to take in the presentations, talks and discussions. The Australian perspective This year has seen a ramping up of interest in negative emissions technologies (NETs) on both national and international levels. In January, the European Academies Science Advisory Council (EASAC) – an independent group that offers science advice to EU policymakers – published a reportlooking at the feasibility and overall potential of NETs from a European perspective. This was followed by the world’s first international conference on NETs, which was held in Sweden in May. The three-day event, which was covered in depth by Carbon Brief, saw scientists debate a range of issues, with a particular focus given to land-based methods such as afforestation and bioenergy with carbon capture and storage (BECCS).
