CO2 emissions and GDP move together over the business cycle. Most climate change researchers would agree with this statement despite the absence of a study that formally analyzes the relationship between emissions and GDP at business cycle frequencies. The paper provides a rigorous empirical...

The European Union (EU) is actively campaigning for the global regulation of carbon emissions generated by maritime bunker fuels because these emissions are presently barely regulated and are projected to increase significantly in the coming decades. However, since a global regulation has not...

CO2 emissions from international shipping, which are currently unregulated, are predicted to rise from 2.7% today to 18% in 2050. International bunker fuel emissions have been excluded from any commitment in the Kyoto Protocol; the UNFCCC conference in Copenhagen also failed to bring about clear...

Trade, economic development, and climate change issues are closely linked and this has significant implications for the design of climate change policies especially for developing countries. Developing countries regard the objective of economic development and growth as being as important as the...

In this paper, we analyze how much the shipping sector could contribute to global CO2 emission reductions from an efficiency point of view. To do this, a marginal abatement cost curve (MACC) for the shipping sector is generated that can be combined with a MACC for conventional CO2 abatement in...

Sustainability has been largely replaced by discounted utilitarianism in contemporary climate-change economics. Our approach rejuvenates sustainability by expanding the conception of the quality of life, along the lines of the UN Human Development Reports, to include not only consumption, but...

Firms talk more about the climate on earnings conference calls when climate matters are more material for a firm, when there is greater shareholder pressure or when it is better prepared for climate-related disclosure. However, there is also large unexplained variation in climate talk. In a...

Global efforts towards mitigating climate change gain momentum; reducing carbon dioxide (CO2) emissions and aiming for zero emissions, or carbon neutrality, is the main goal. Economic factors are main determinants of CO2 emissions coming from production and energy consumption. This paper aims to...

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...
