Most climate policy pathways require gigaton-scale removal of carbon dioxide (CO2) within 30-80 years to keep global warming below 2⁰C. Even with full deployment of all known low-carbon measures, some greenhouse gas emissions arising from human activities (industry, transport and agriculture) will need to be offset in order to achieve net-zero emissions. The £8.6m Greenhouse Gas Removal (GGR) research programme, co-supported by three Research Councils and the UK government, addresses the many uncertainties relating to the cost effectiveness, scalability, and wider environmental and societal consequences of balancing the climate equation through ‘negative emissions’. Eleven component projects (4 consortia, 7 topic-specific projects) are involved over the period 2017-2021, with a wide range of partners and collaborators.
A new UK-based Carbon Removal Network will hold its launch meeting in London on the evening of 27 February 2019. The aim of the group is to bring together professionals who are interested in or already engaged in removing greenhouse gases from the atmosphere. Further information and free registration is available via Eventbrite. The launch… Read more New carbon removal network: London launch meeting 27 February
Increasing soil organic carbon is one of the most straightforward means of removing carbon from the atmosphere – reversing the large amounts (globally more than 100 Gt) that have been released by agriculture. Eight measures to achieve that goal were identified in a Nature article print-published on 6 December, with the paper’s authorship… Read more The many benefits of increasing soil carbon
Two international conferences on carbon removal (as negative emissions) were held in 2018. The first in Gothenburg, 22-24 May; the second, in Canberra, 30-31 October. Whilst separately organized, both attempted comprehensive science responses to crucial climate change questions: what contribution, together and on their own, could different CO2 removal techniques make towards the goals of… Read more Canberra GGR conference: policy summary and presentations now online
Dr Phil Renforth’s GGR research project, on carbon removal in the iron and steel industry, featured prominently on BBC1 TV news on 29 November 2018, with an associated BBC Science and Environment online article. Filmed on the Blaenarvon slag heap in South Wales, Phil and his colleague Sarah Gore demonstrated to David Shukman how silicate… Read more Slag-based carbon removal on BBC TV news
