Based on the Publications of the IPCC Working Groups I to III the question of the influence of the entropy increase since the industrialization around 1750 on the current climate development is answered both in general terms as well as through a first quantitative approach. It is shown that the...

One important element of the current policy debate on what measures should be taken to reduce greenhouse gas emissions is the controversy over the costs of reducing those emissions. "Top-down" macroeconomic and general equilibrium models give much higher estimates of the costs than "bottom-up"...

Canada's natural capital — its resources, ecosystems and wildlife — are indispensable to the productivity of industry. Despite this, both the public and private sectors have failed to adequately factor in the consequences of production and consumption on the natural environment. There is a...

This chapter examines government policy alternatives for protecting the environment. We compare environmentally motivated taxes and various non-tax environmental policy instruments in terms of their efficiency and distributional impacts. Much of the analysis is performed in a second-best setting...

In this reply, I oppose and further debate some of the points raised in Mr. Tehrani's comment (2010). In addition, I show that, when dealing with short-run linear-programming models with not-adjusted-to-demand capacities, Aumann-Shapley prices can be considered as an attempt to recreate long-run...

As oil refining is a multiproduct industrial activity, there are innumerable ways to allocate a refinery’s CO2 emissions among the various refined products. The linear-programming models used to manage refineries may serve to compute the marginal contribution of each finished product to the...

Linear programming is widely used by multiproduct oil-refining firms which minimize a refinery’s variable cost under a set of constraints. In addition to operating costs, this variable cost can include the cost associated with the refinery’s CO2 emissions. We suggest a quite general approach...

This paper concerns optimal emissions of greenhouse gases when catastrophic consequences are possible. A numerical model is presented which takes into account both continuous climate-feedback damages as well as the possibility of a catastrophic outcome. The uncertainty in the model concerns...
