How can Bioenergy with Carbon Capture and Storage (BECCS) contribute to meeting 2 degrees? Policy card D2a

How can Bioenergy with Carbon Capture and Storage (BECCS) contribute to meeting 2 degrees? Policy card D2a Most computer modelled scenarios that limit global warming to below 2°C rely on some amount of CO2 removal from the atmosphere later this century.1 BECCS is a process that has the potential to remove carbon from the atmosphere. … Read more

How plausible is a rapid global increase in the deployment of Bioenergy with Carbon Capture and Storage (BECCS)? Policy Card D1a D1b

Most future scenarios of the energy systems needed to avoid dangerous climate change involve the removal of atmospheric carbon dioxide later this century (referred to as a ‘negative emissions’ technology). BECCS is currently the only technology with the potential to remove carbon from the atmosphere at a global scale, whilst meeting future rising energy needs … Read more

Exploring the feasibility of low-carbon scenarios using historical energy transitions analysis (C3)

This study analyses the dynamics pf previous energy transitions with a view to applying these insights to assess the feasibility of low-carbon scenarios produced by a global energy systems model (the Grantham Institute’s TIMES Integrated Assessment Model, TIAM-Grantham). The study first reviews recent literature investigating past energy transitions, as well as how the feasibility of … Read more

Synthesising existing knowledge on the feasibility of BECCS: Workshop report (D1.b)

There is a growing and significant dependence on biomass energy with carbon capture and storage (BECCS) in future emission scenarios that do not exceed 2°C warming; over 100 of the 116 scenarios associated with concentrations between 430–480 ppm CO2 depend on BECCS to deliver global net negative emissions in the IPCC Fifth Assessment Report (AR5) … Read more

Overshoot scenarios and their climate response (A3)

This report reviews the current literature regarding “overshoot” scenarios where some aspect of the climate such as the temperature or GHG concentrations temporarily exceed a given target. The aim is to characterise such scenarios from Integrated Assessment Models (IAM) and where possible the climate to these scenarios, however most simulations with comprehensive climate models consider … Read more

Planetary limits to BECCS negative emissions (D2.a)

This study focuses on the planetary limits to BECCS from first generation annual bio-energy (BE) crops coupled with Carbon Capture and Storage (CCS). The acknowledged threat of many damaging aspects of climate change over the next century and beyond has prompted research into ways to reduce and reverse the recent increase in the amount of … Read more

Synthesising existing knowledge on the feasibility of BECCS (D1a)

There is a growing and significant dependence on biomass energy with carbon capture and storage (BECCS) in future emission scenarios that do not exceed 2°C warming; over a hundred of the 116 scenarios associated with concentrations between 430–480 ppm CO2 depend on BECCS to deliver global net negative emissions in the IPCC Fifth Assessment Report (AR5) … Read more

Mitigation policy cards

A series of  policy cards providing up-to-date evidence for policy questions relating to climate change mitigation. Policy card 1: What is the scale and challenge of the energy system transition required to meet long-term climate goals? Achieving emissions consistent with a 50% chance of remaining below 2°C by 2100 will require large changes in the energy system over … Read more

An updated view of tipping points and the relevance for long-term climate goals (A5)

While some aspects of climate change can be viewed as becoming proportionately larger with increasing forcings, other aspects may feature more complex, nonlinear behaviour. This can include abrupt and/or irreversible change, which may be associated with key thresholds. Such behaviour must be considered differently in assessments of the potential benefits of mitigation: it implies, for … Read more
