A Consumption-Based Approach to Carbon Emission Accounting – Sectoral Differences and Environmental Benefits

In recent years there has been growing concern about the emission trade balances of countries. This is due to the fact that countries with an open economy are active players in international trade. Trade is not only a major factor in forging a country’s economic structure, but contributes to the movement of embodied emissions beyond country borders. This issue is especially relevant from the carbon accounting policy and domestic production perspective, as it is known that the production-based principle is employed in the Kyoto agreement. The research described herein was designed to reveal the interdependence of countries on international trade and the corresponding embodied emissions both on national and on sectoral level and to illustrate the significance of the consumption-based emission accounting. It is presented here to what extent a consumption-based accounting would change the present system based on production-based accounting and allocation. The relationship of CO2 emission embodied in exports and embodied in imports is analysed here. International trade can blur the responsibility for the ecological effects of production and consumption and it can lengthen the link between consumption and its consequences. Input-output models are used in the methodology as they provide an appropriate framework for climate change accounting. The analysis comprises an international comparative study of four European countries (Germany, the United Kingdom, the Netherlands, and Hungary) with extended trading activities and carbon emissions. Moving from a production-based approach in climate policy to a consumption-based principle and allocation approach would help to increase the efficiency of emission reductions and would force countries to rethink their trading activities in order to decrease the environmental load of production activities. The results of this study show that it is important to distinguish between the two emission accounting approaches, both on the global and the local level.

Correlations between garden design plant applications and climate change

Possible effects of climate change means great challenges to landscape design professionals in Hungary. Our climate will shift towards the Mediterranean and we have to prepare for this with among others, choosing correctly the plants to be planted. Teaching garden design dendrology has not recognized yet the necessity and urgency of this matter. Quick measures are required due to the long life-time and slow development of woody taxons. This paper presents the double relationship between landscape design and climate change emphasizing the outdoor architectural methods of adjustment. Such techniques recognized abroad are presented like precipitation drainage by vegetation and extensive green roof. Finally the effects of climate change on ornamental plants application are presented together with the associated project started at the Corvinus University of Budapest in 2010.
