There are several well-established facts in the literature on climate change. First, is that international
agreement are not able to sustain high levels of participation and deep emission cuts at the same time.
Second, with appropriate use of sticks and carrots, they are. Third, that by deterring non-participation, we
deter non-compliance as well. Fourth, from the story of the Montreal Protocol it follows that when necessary,
countries can cooperate on the Pareto-efficient outcome of the underlying game. Lastly, climate change poses
an existential threat to humanity and we do not have much time left to stop. Now, we nonetheless observe
suboptimal levels of individual abatement and modest levels of cooperation. Thus, the purpose of this study
is to establish the role of unilateral actions in the solution of the collective problem of climate change and to
investigate whether external shocks can increase international cooperation. Using game-theoretic approach
a model was built which incorporates uncertainty in the form of damages from the natural disasters that
have a certain probability of occurring and can be altered by the levels of players’ abatement. There are
three major findings: (1) No IEA will be stable unless it requires unilaterally chosen levels of abatement; (2)
time-inconsistent players tend to procrastinate, but under certain values of parameters can turn into timeconsistent
due to higher perceived probability of future damages; and (3) time-consistent players can, on
the contrary, become time-inconsistent and deviate from transition to business-as-usual over time. External
shocks will have no effect on the chosen abatement levels unless politicians exhibit some form of statistical
biases when estimating the probability of future damages. To increase global abatement, it is necessary that
countries unilaterally set more ambitious targets. Otherwise free riding and non-compliance are unavoidable.
