Sentences with phrase «called negative emissions»

Adding to the skepticism over the feasibility of air capture is that there are other, cheaper ways to create the so - called negative emissions.

This has sparked a growing realisation that so - called negative emissions might be necessary to meet the goals of Paris, where an overspend against the carbon budget is paid back by pulling CO2 from the air.

While this is normally a slow natural process during which minerals chemically bind CO2, technological upscaling could make this relevant for so - called negative emissions to help limit climate risks.

Not exact matches

If we embark on a path that is equivalent to setting emissions to zero now (say by having a period of negative emissions in the 2035 to 2050 time frame), and call the sequestration we accomplish mitigation then mitigation can arrest climate change, make adaptation unneeded and bring us to a safe concentration of carbon dioxide in the atmosphere as Hansen has pointed out.

Carbon removal and storage coupled with drawing down fossil fuel use is called «negative emissions.»

In particular, these models love a technology called «bioenergy carbon capture and sequestration (BECCS)» because it has negative emissions — you grow biomass, harvest it and burn it for electricity, and then store the pollution underground.

Many commentators and policymakers have also argued that so - called «negative emissions technologies,» such as BECCS, will be critical to meet the Paris Agreement's objectives to «achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century.»

In recent years, a number of climate change commentators, non-governmental organizations, and intergovernmental organizations have discussed the potential need for so - called «negative greenhouse gas emissions» strategies.

Achieving negative emissions will involve what the analysis calls «the deployment of uncertain and at present controversial technologies, including biomass energy with carbon capture and storage.»

The other way to get to negative emissions is through something called Direct Air Capture, where a device sucks carbon dioxide straight from the atmosphere like a vacuum.

It seems likely that large scale removal of greenhouse gases from the atmosphere may be called for: so - called «negative emissions».

If we embark on a path that is equivalent to setting emissions to zero now (say by having a period of negative emissions in the 2035 to 2050 time frame), and call the sequestration we accomplish mitigation then mitigation can arrest climate change, make adaptation unneeded and bring us to a safe concentration of carbon dioxide in the atmosphere as Hansen has pointed out.

Peters is a researcher who is on the record stating that he thinks there's little chance of holding warming to 2 degrees Celsius unless we come up with so - called «negative emissions» technologies that allow us to actively withdraw carbon dioxide from the atmosphere later in the century.
