The 2^nd International Conference on Negative CO₂ Emissions will be held at Chalmers University of Technology, Gothenburg, Sweden, June 14-17, 2022. The purpose of this conference series is to bring together a wide range of scientists, experts and stakeholders, in order to engage in various aspects of research relating to negative CO₂ emissions. This will include various negative emission technologies, climate modelling, climate policies and incentives. The main topics of the conference, around which the sessions will be built, include:

• BECCS
• Biospheric storage
• Cross-cutting sessions
• Direct air capture
• Enhanced weathering
• Modeling
• Ocean alkalization

For details, please go to the Sessions/Topics tab (under Information).

Background

The objective of the Paris Agreement is to limit global warming to well below 2ºC, and to pursue efforts to limit the temperature increase to 1.5ºC. The carbon budget is the amount of carbon dioxide that we can emit while still limiting global temperature rise to a given level, for example 1.5ºC.

The exact size of the carbon budget is uncertain and depends on many factors, including potential future warming of non-CO₂ climate forcers. This said, the remaining budgets for limiting the warming to 1.5ºC or 2ºC have been estimated at about 420 and 1170 Gt of CO₂ . With unchanged present emissions at about 40 Gt CO₂/year these budgets would be exhausted in as few as 10 and 30 years, respectively. Most of the IPCC emission scenarios that meet a global two-degree target in 2100 overshoot the carbon budget at first and then remove the excess carbon with large negative emissions, typically on the order of 400‑800 Gt CO₂ up to 2100.

At the same time as negative emissions appear to be indispensable to meet adopted climate targets, the large future negative emissions assumed in climate models have been questioned and warnings have been raised about relying on very large and uncertain negative emissions in the future. With the future climate at stake, a deeper and fuller understanding of the various aspects of negative emissions is needed.

Abstract submission is now open – Click here to submit your abstract.

The conference will be a hybrid event with physical, “normal” oral presentations, and also pre-recorded presentations that are available only digitally for those who cannot attend in person. Pre-recorded presentations will be made available on-line so that all participants (online or on-site) of the conference can see them at any time during the conference. The pre-recorded presentations will also include a “chat” to make it possible to pose questions to the author. When you submit an abstract you will need to select either oral or pre-recorded presentation.

If you have a previously accepted abstract, i.e. for the submissions made before the pandemic and the postponement of the conference, you will need to submit your abstract again. However, your previous acceptance is still valid and upon submitting you must choose “previously accepted”. Thus, your abstract will not be reviewed again.

Please note the following requirements:
• Submission deadline: December 1, 2021.
• Use appropriate template for submission.
• Submission must be in pdf file format.
• Name the document “Last name of first author, First name of first author”, e.g.: ”Scheele, Carl Wilhelm”.

When the review is complete, corresponding authors will be notified via e-mail whether their contribution has been (a) selected for oral presentation, (b) selected for poster presentation, or (c) rejected. Paper submission is compulsory for oral presenters – both on-site and digital – and optional for poster presenters.
