Reliance on negative-emission concepts locks in humankind's carbon addiction In December 2015, member states of the United Nations Framework Convention on Climate Change (UNFCCC) adopted the Paris Agreement, which aims to hold the increase in the global average temperature to below 2°C and to pursue efforts to limit the temperature increase to 1.5°C. The Paris Agreement requires that anthropogenic greenhouse gas emission sources and sinks are balanced by the second half of this century. Because… 
Understanding Negative Emissions From BECCS
Changes in our climate are driven by human activity such as agriculture, deforestation and burning coal, oil and gas. The single most significant driver of climate change is the increase in the
Co-producing climate policy and negative emissions: trade-offs for sustainable land-use
Non-technical summary Under the Paris Agreement, nations have committed to preventing dangerous global warming. Scenarios for achieving net-zero emissions in the second half of this century depend on
Climate–carbon cycle uncertainties and the Paris Agreement
The Paris Agreement1 aims to address the gap between existing climate policies and policies consistent with “holding the increase in global average temperature to well below 2 C”. The feasibility of
Higher Carbon Prices on Emissions Alone Will Not Deliver the Paris Agreement
Summary Limiting global warming to 2°C by 2100 requires anthropogenic CO2 emissions to reach zero by 2070 and become negative afterwards; therefore, large-scale carbon dioxide removal (CDR) from the
Negative emissions—Part 1: Research landscape and synthesis
TLDR
An in-depth assessment of the role of NETs in climate change mitigation scenarios, their ethical implications, as well as the challenges involved in bringing the various NETs to the market and scaling them up in time are clarified.
A new scenario logic for the Paris Agreement long-term temperature goal
TLDR
This work draws on insights from physical science to propose a scenario framework that focuses on capping global warming at a specific maximum level with either temperature stabilization or reversal thereafter, and makes questions of intergenerational equity into explicit design choices.
Governing Experimental Responses: Negative Emissions Technologies and Solar Climate Engineering
Parties to the 2015 Paris Agreement strive to ‘hold . . . the increase in the global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature
The role of negative carbon emissions in reaching the Paris climate targets: The impact of target formulation in integrated assessment models
Global net-negative carbon emissions are prevalent in almost all emission pathways that meet the Paris temperature targets. In this paper we generate and compare cost-effective emission pathways that
Negative emissions technologies and carbon capture and storage to achieve the Paris Agreement commitments
TLDR
A new analysis of all global CCS projects and model the build rate out to 2050, deducing this is 100 times too slow, which means no CCS means no 2°C, and a first urgent action for all countries is to commercially assess their CO2 storage.
Negative emissions and international climate goals—learning from and about mitigation scenarios
For aiming to keep global warming well-below 2 °C and pursue efforts to limit it to 1.5 °C, as set out in the Paris Agreement, a full-fledged assessment of negative emission technologies (NETs) that

Biophysical and economic limits to negative CO2 emissions
To have a >50% chance of limiting warming below 2 °C, most recent scenarios from integrated assessment models (IAMs) require large-scale deployment of negative emissions technologies (NETs). These
Paris Agreement climate proposals need a boost to keep warming well below 2 °C
TLDR
Substantial enhancement or over-delivery on current INDCs by additional national, sub-national and non-state actions is required to maintain a reasonable chance of meeting the target of keeping warming well below 2 degrees Celsius.

TLDR
Results indicate that soil carbon sequestration and biochar have useful negative emission potential and that they potentially have lower impact on land, water use, nutrients, albedo, energy requirement and cost, so have fewer disadvantages than many NETs.
