Hemiparasitic plants display a unique strategy of resource acquisition combining parasitism of other species and own photosynthetic activity. Despite the active photoassimilation and green habit, they acquire substantial amount of carbon from their hosts. The organic carbon transfer has a crucial influence on the nature of the interaction between hemiparasites and their hosts which can oscillat...

Australia’s transport greenhouse gas (GHG) emissions are high and continue to grow, with current levels approximately one-third higher than in 1990 and increasing by around 1% annually. Efforts to curtail and reverse this growth have not been successful to date. In recent times, national policy development and debate has centred on market-based mechanisms to reduce GHG emissions, namely an emis...

The spatial representation of forest cover and forest parameters is a prerequisite for undertaking a systems approach to the full and verified carbon accounting of forest ecosystems over large areas. This study focuses on Ukraine, which contains a diversity of bioclimatic conditions and natural landscapes found across Europe. Ukraine has a high potential to sequester carbon dioxide through affo...

The emission targets adopted in the Kyoto Protocol far exceed the likely level of emissions from Russia and Ukraine. These countries could sell their “bubbles” if the Protocol enters into force and industrialized countries establish an international emission trading system. Using the most recent, comprehensive scenarios for emissions of carbon dioxide from the energy system we estimate that dur...

We introduce endogenous directed technical change into integrated climate policy assessment. Our model builds on state-of-the-art theory as well as econometric data. We apply our model to the assessment of a carbon budget based climate policy. Motivated by the announcement of international transfers during recent climate policy negotiations, we vary the begin of endogenous international transfe...

The atmospheric budget of methyl bromide (CH(3)Br), an ozone-depleting gas, is highly uncertain, because it has complex sources and sinks. Although oceans, biomass burning, and industrial production are identified as the major sources, the fraction of CH(3)Br that is contributed by each source is not well known. A mass-balance approach that exploits differences in the carbon isotopic signature ...
