CNBC: Climate experts are worried about the toughest carbon emissions for companies to capture

"Scope 3 carbon emissions, or those not part of operations or under direct control, represent the majority of the carbon footprint for most companies, in some cases as high as 85% to 95%. As companies lay out ambitious carbon reduction targets and net-zero pledges for the decades ahead, slow progress on tracking Scope 3 emissions has climate experts worried."

Vox EU: A policy framework for achieving negative emissions

"This column argues that an alternate type of policy, called 'carbon shares', can limit emissions as efficiently as carbon taxes or caps while also properly incentivising negative emissions."

Zickfeld, Kirsten; et al. (2021): Asymmetry in the climate–carbon cycle response to positive and negative CO2 emissions

Zickfeld, Kirsten; Azevedo, Deven; Mathesius, Sabine; Matthews, H. Damon (2021): Asymmetry in the climate–carbon cycle response to positive and negative CO2 emissions. In Nat. Clim. Chang., pp. 1–5. DOI: 10.1038/s41558-021-01061-2.

" It is commonly assumed that the climate–carbon cycle response to a negative CO2 emission is equal in magnitude and opposite in sign to the response to an equivalent positive CO2 emission. Here we test the hypothesis that this response is symmetric by forcing an Earth system model with positive and negative CO2 emission pulses of varying magnitude and applied from different climate states."

Hannah, Lee (2022): Chapter 21 - Mitigation: Reducing Greenhouse Gas Emissions, Sinks, and Solutions

Hannah, Lee (2022): Chapter 21 - Mitigation: Reducing Greenhouse Gas Emissions, Sinks, and Solutions. In Lee Jay Hannah (Ed.): Climate change biology. Third edition. London, [Amsterdam]: Academic Press, pp. 439–472.

"Stopping climate change requires much more than emissions reductions: it requires stabilizing atmospheric greenhouse gas (GHG) concentrations. In the absence of large new additional sinks for CO2 and other GHGs, stabilization equates to reducing emissions nearly to zero. In turn, near-zero emissions means complete transition of the world's energy supply to renewable (non-CO2-emitting) sources. This is a huge task—one that will need to be accomplished in stages."

Mercator Research Institute on Global Commons and Climate Change (2021): Cleaning up emissions from our atmosphere

Mercator Research Institute on Global Commons and Climate Change (2021): Cleaning up emissions from our atmosphere. MCC Policy Brief No. 2 - Carbon Removal. June 2021.

"The issue of "negative emissions" is moving up the agenda, and governments are already setting concrete goals. Reducing greenhouse gas emissions quickly towards zero is not enough to achieve the temperature targets of the Paris global climate agreement."

Sasaki, Nophea; et al. (2021): Predicting carbon emissions, emissions reductions, and carbon removal due to deforestation and plantation forests in Southeast Asia

Sasaki, Nophea; Myint, Yadanar Yè; Abe, Issei; Venkatappa, Manjunatha (2021): Predicting carbon emissions, emissions reductions, and carbon removal due to deforestation and plantation forests in Southeast Asia. In Journal of Cleaner Production 312, p. 127728. DOI: 10.1016/j.jclepro.2021.127728.

"Here, we assessed carbon stocks, carbon emissions, removals, and reductions due to deforestation and management of the natural (NFs) and plantation forests (PFs) in Southeast Asia. We found that area of NFs declined about 1.09 million ha or 0.52% yr−1 over the last 20 years but only approximately 0.29 million ha was converted to PFs."
