Die Rubrik »Kurz zum Klima« erscheint nun bereits seit drei Jahren mit nahezu 60 Ausgaben. Dieser Beitrag greift drei Themen aus den Bereichen Energie-, Klima- und Umweltpolitik – das Reserven-Produktions-Verhältnis, die weltweite CO2-Reduktion und das Problem der Überfischung – erneut...

Global regulations involving clean energy technologies have evolved in recent decades. Such evolution came as a result of technological disparities between the North and the South. Such regulatory changes came because of the failure of developed nations to assist developing countries in...

This paper describes the design of a new emissions trading scheme which is based on the principle of equity. The scheme is based on the principle that the atmosphere is common property to all humankind, and as such, all people have an unalienable right over air. As such there is little...

The focus of the green paradox literature has been either on demand-side climate policies or on effects of technological changes. The present paper addresses the question of whether there also might be some kind of green paradox related to supply-side policies, i.e. policies that permanently...

We use a two-period model to investigate intertemporal effects of cost reductions in climate change mitigation technologies for the power sector. With imperfect climate policies, cost reductions related to carbon capture and storage (CCS) may be more desirable than com-parable cost reductions...

We investigate the socially optimal anthropogenic intervention into the global carbon cycle. The limiting factor for this intervention is the accumulation of carbon in the atmosphere, which causes global warming. We apply a simplified two-box model to incorporate aspects of the global carbon...

The Green Paradox states that, in the absence of a tax on CO2 emissions, subsidizing a renewable backstop such as solar or wind energy brings forward the date at which fossil fuels become exhausted and consequently global warming is aggravated. We shed light on this issue by solving a model of...

Optimal climate policy is studied. Coal, the abundant resource, contributes more CO2 per unit of energy than the exhaustible resource, oil. We characterize the optimal sequencing oil and coal and departures from the Herfindahl rule. 'Preference reversal' can take place. If coal is very dirty...

Our main message is that it is optimal to use less coal and more oil once one takes account of coal being a backstop which emits much more CO2 than oil. The way of achieving this is to have a steeply rising carbon tax during the initial oil-only phase, a less-steeply rising carbon tax during the...
