Negative emission farming [PDF]

Journal of Soil and Water Conservation, 2021
In comparison with levels in 2000, global carbon dioxide (CO2) has increased by 43.5 ppm to 414.4 ppm during 2020, an increase of 12%. Indeed, concentration of atmospheric CO2 now is higher than at any time during the past 3.6 million years (Stein 2021).

Mapping Multi-Level Policy Incentives for Bioenergy With Carbon Capture and Storage in Sweden

Frontiers in Climate, 2020
Bioenergy with carbon capture and storage (BECCS) is considered a key mitigation technology in most 1.5–2.0°C compatible climate change mitigation scenarios. Nonetheless, examples of BECCS deployment are lacking internationally. It is widely acknowledged

Enhanced weathering potentials—the role of in situ CO2 and grain size distribution

Frontiers in Climate, 2022
The application of rock powder on agricultural land to ameliorate soils and remove carbon dioxide (CO2) from the air by chemical weathering is still subject to many uncertainties.

Potential of Land‐Neutral Negative Emissions Through Biochar Sequestration

Earth's Future, 2022
Negative emissions (NE) are under discussion as elements of mitigation strategies aiming to achieve the climate targets of the Paris Agreement. However, biomass‐based NE technologies such as bioenergy with carbon capture and storage (BECCS) require vast ...

Transport Cost for Carbon Removal Projects With Biomass and CO2 Storage

Frontiers in Energy Research, 2021
Strategies to remove carbon from the atmosphere are needed to meet global climate goals. Promising strategies include the conversion of waste biomass to hydrogen, methane, liquid fuels, or electricity coupled with CO2 capture and storage (CCS).

Endotoxin emissions from commercial composting activities [PDF]

, 2009
This paper describes an exploratory study of endotoxin emissions and dispersal from a commercial composting facility. Replicated samples of air were taken by filtration at different locations around the facility on 10 occasions. Measurements were made

Environmental sustainability of negative emissions technologies

Sustainable Production and Consumption, 2022
Negative emissions technologies (NETs) are expected to play a significant role in mitigating climate change. However, there are also concerns that a large scale deployment of NETs may cause various environmental impacts due to the use of land, water and energy resources.

Towards true climate neutrality for global aviation: a Negative Emissions Fund for Airlines [PDF]

, 2022
What would it take for aviation to become climate-neutral by 2050? We develop and model a trajectory for aviation to reduce its CO2 emissions by 90% by 2050, down to a level where all residual emissions can be removed from the atmosphere without crowding

The Future of (Negative) Emissions Trading in the European Union

, 2020
Under the European Union Emissions Trading System (EU ETS), operators must surrender allowances corresponding to the emissions of greenhouse gases (GHG) from their installations.

Research priorities for negative emissions

Environmental Research Letters, 2016
Carbon dioxide removal from the atmosphere (CDR)—also known as ‘negative emissions’—features prominently in most 2 °C scenarios and has been under increased scrutiny by scientists, citizens, and policymakers.
