Dear colleagues,
I'd like to inform you of our new paper published today in Climate
Policy which is free online at the link below. We researched the impact
of carbon offsetting on wider carbon management practices and outcomes
amongst universities. We find no moral licensing, moral hazard or
rebound effect amongst adopters of carbon offsets. In fact, adopters
undertook more carbon management practices, had earlier net zero targets
and reduced their carbon emissions slightly more than did non-adopters.
We argue that under the polluter pays principle polluters of carbon have
a duty to clean up their pollution and compensate those damaged. In
fact, plausibly, Not offsetting carbon is moral hazard as it involves to
a large extent wealthier groups, who are better insulated from impacts,
emitting pollution which places costs and risks on the most vulnerable
who have caused the least pollution.

Abstract. Solar Radiation Modification (SRM) is increasingly being
discussed as a potential tool to reduce global and regional
temperatures to buy time for conventional carbon mitigation measures
to take effect. However, most simulations to date assume SRM as an
additive component to the climate change toolbox, without any physical
coupling between mitigation and SRM. In this study we analyse one
aspect of this coupling: How renewable energy (RE) capacity, and
therefore decarbonization rates, may be affected under SRM deployment
by modification of photovoltaic (PV) and concentrated solar power
(CSP) production potential. Simulated 1-hour output from the Earth
System Model CNRM-ESM2-1 for scenario-based experiments are used for
the assessment. We find that by the end of the century, most regions
experience an increased number of low PV and CSP energy weeks per year
under SAI (Stratospheric Aerosol Injections) compared to the
moderately ambitiously mitigated scenario SSP245. Compared to the
unmitigated SSP585 scenario, while the increase in low energy weeks is
still dominant, some areas see fewer low PV or CSP energy weeks under
SAI. A substantial part of the decrease in potential with SAI compared
to the SSP-scenarios is compensated by optically thinner upper
tropospheric clouds under SAI. Our study suggests that using SAI to
reduce high-end global warming to moderate global warming could pose
increased challenges for meeting energy demand with solar renewable
resources.
