population growth can greatly impact on greenhouse gas emission pattern in the future. considering the importance of population growth in climate change studies, the present research concentrates on the population growth of the middle east in the late 21th century based on the iiasa population scenarios. under the projections of a1-b1 scenario, the world’s population will grow up to 8.7 billion...

The pollution haven hypothesis suggests that unilateral environmental regulation could cause adverse “competitiveness” impacts on domestic manufacturers as they lose market share to foreign competitors and relocate production activity – and emissions – to unregulated economies. This is particularly troubling in the case of mitigating climate change, a global pollution externality, where there a...

Nitrous oxide (NzO) is emitted from wastewater treatment processes. It is known as a greenhouse gas that contributes to global warming (over 200 times more per molecule than carbon dioxide) and to the destruction of the ozone layer. It is therefore of great importance to develop technology that can suppress N20 emission. The effects of an anoxic period on NzO emission and nitrogen removal were ...

We have developed an integrated model system, EVA (Economic Valuation of Air pollution), based on the impact-pathway chain, to assess the health-related economic externalities of air pollution resulting from specific emission sources or sectors, which can be used to support policymaking with respect to emission control. Central for the system is a newly developed tagging method capable of calcu...

One problem in international climate policy is the refusal of large developing countries to accept emission reduction targets. Brazil, China and India together account for about 20% of today’s CO2 emissions. We analyse the case in which there is no international agreement on emission reduction targets, but countries do have domestic targets, and trade permits across borders. We contrast two sce...

In November 2009, China pledged a 40–45% decrease in CO2 emissions per GDP by 2020, as compared with the 2005 level. Although carbon intensity (emission) targets by nature are ambiguous, this study demonstrates that China’s pledge is consistent with the current Chinese domestic agenda that simultaneously pursues economic growth and energy security. The target numbers in the pledge seem reasonab...
