摘要

The fishing sector is a candidate for efficient climate policies because it is commonly exempted from greenhouse gas taxes and the fundamental problem of using a common pool resource is far from optimally solved. At the same time, fisheries management has other objectives. This study uses Swedish fisheries to analyse how the fishing sector and its climate impact are affected by regulations aiming at: (1) solving the common pool problem (2) taxing greenhouse gas emissions and (3) maintaining small-scale fisheries. The empirical approach is a linear programming model where the effects of simultaneously using multiple regulations are analyzed. Solving the common pool problem will lead to a 30 % reduction in emissions and substantially increase economic returns. Taxing greenhouse gas emissions will further reduce emissions. Policies for maintaining the small-scale fleet will increase the size of this fleet segment, but at the cost of lower economic returns. However, combining this policy with fuel taxes will reduce the size of the small-scale fleet, thus counteracting the effects of the policy. If taxation induces fuel-saving innovations, it is shown that this will affect not only emissions and fleet structure, but also quota uptake.
