I can't understand how these comments get though the review process.
They probably mean reducing the 'effects' of emissions.

Can some one explain how SAI reduces emissions of CO2, CH4, N2O and
fluorocarbons?

*Abstract*
An artificial method of injecting sulfate aerosols into the
stratosphere to reduce greenhouse gas emissions (GHGs) is called
stratospheric aerosol injection (SAI). By releasing sulfates into
the atmosphere, volcanic eruptions naturally disperse sunlight and
lower the temperature of the Earth’s surface. This technique
attempts to replicate that process. SAI has drawn interest as a
possible geoengineering technique to mitigate the effects of
climate change. It does, however, present important ethical,
technical, and environmental issues that need to be properly
resolved before deployment is ever discussed. Regional climate
alteration, ozone layer depletion, disruption of precipitation
patterns, and negative health consequences on humans are among the
possible dangers linked to solar radiation exposure. Concerns
about consent, equity, governance frameworks, and unexpected
repercussions are all included in the category of ethical
considerations. Moreover, there are unknowns about the best
injection heights and aerosol volume needed for efficient cooling
while reducing additional hazards. To make informed judgments in
the future regarding the sustainability and practicality of using
SAI as a tool to reduce greenhouse gas emissions, it is imperative
to have a thorough grasp of these intricate concerns. Therefore,
the current chapter will analyze the concept of SAI and its
anticipated benefits and challenges.
