The calculation of dynamic ecological footprint on the basis of the dynamic input-output model

The Leontief input-output model is widely used to determine the ecological footprint of consumption in a region or a country. It is able to capture spillover environmental effects along the supply change, thus its popularity is increasing in ecology related economic research. These studies are static and the dynamic investigations are neglected. The dynamic Leontief model makes it possible to involve the capital and inventory investment in the footprint calculation that projects future growth of GDP and environmental impacts. We show a new calculation method to determine the effect of capital accumulation on ecological footprint.

Living within a One Planet reality: the contribution of personal Footprint calculators

During the last 50 years, humanity's Ecological Footprint has increased by nearly 190% indicating a growing unbalance in the human-environment relationship, coupled with major environmental and social changes. Our ability to live within the planet's biological limits requires not only a major re-think in how we produce and distribute 'things', but also a shift in consumption activities. Footprint calculators can provide a framing that communicates the extent to which an individual's daily activities are compatible with our One Planet context. This paper presents the findings from the first international study to assess the value of personal Footprint calculators in guiding individuals towards sustainable consumption choices. It focuses specifically on Global Footprint Network's personal Footprint calculator, and aims to understand the profile of calculator users and assess the contribution of calculators to increasing individual awareness and encouraging sustainable choices. Our survey of 4245 respondents show that 75% of users resided in 10 countries, 54% were aged 18–34 years and had largely used the calculator within an educational context (62%). The calculator was considered a valuable tool for knowledge generation by 91% of users, and 78% found it useful to motivate action. However, only 23% indicated the calculator provided them with the necessary information to make actual changes to their life and reduce their personal Footprint. The paper discusses how and why this personal Footprint calculator has been effective in enhancing individuals' understanding of the environmental impact of their actions, framing the scale of the problem and empowering users to understand the impacts of different lifestyle choices. Those individual-level and system-level changes needed to generate global sustainability outcomes are also discussed. Similar to other calculators, a gap is also identified in terms of this calculator facilitating individuals to convert new knowledge into action

On production and abatement time scales in sustainable development. Can we loosen the sustainability screw ?

In this paper we carry out a preliminary exploration of a time scales' conjecture, which postulates that "reasonable" notions of sustainability must include a suitable synchronisation of time scales of both the processes of human development and those of the natural environment. We perform our analysis within a coarse, ?ve variable, model of man-nature interactions expressed as a system of differential equations where production and human capital are coupled with both renewable and non-renewable natural resource. We demonstrate a phenomenon that we name the "sustainability screw" that describes a spiral like trajectory of the three key variables: non-renewable and renewable resources as well as the production capital. Under many plausible scenarios, this spiral tends unacceptably fast to an undesirable equilibrium. However, we also show that by adjusting the ratio of "intensity of production effort" and "intensity of abatement effort", parameters of the relative time scales of production and natural recovery processes can be altered in a manner that produces, arguably, more sustainable trajectories.sustainable optimization systems, viability, multiple time scale

Applying consumer responsibility principle in evaluating environmental load of carbon emissions

There is a need for a proper indicator in order to assess the environmental impact of international trade, therefore using the carbon footprint as an indicator can be relevant and useful. The aim of this study is to show from a methodological perspective how the carbon footprint, combined with input- output models can be used for analysing the impacts of international trade on the sustainable use of national resources in a country. The use of the input-output approach has the essential advantage of being able to track the transformation of goods through the economy. The study examines the environmental impact of consumption related to international trade, using the consumer responsibility principle. In this study the use of the carbon footprint and input-output methodology is shown on the example of the Hungarian consumption and the impact of international trade. Moving from a production- based approach in climate policy to a consumption-perspective principle and allocation, would also help to increase the efficiency of emission reduction targets and the evaluation of the ecological impacts of international trade

Benchmarking local ecological performance using ecological footprint accounts

Ecological footprint is good at telling us how much we weight relative to global ecological ressources. However it tells us nothing on their geographical origin and makes no distinction be-tween ecological ressources used from distant or local land. Moreover it does not measure theintensity of exploitation of soils or other sustainability considerations like biodiversity loss. There-fore the results provided by the footprint calculation are barely suitable for planning and policydesign, as information on real use of local land is lost in the process of calculation. This issuesare well known and are part of the research agenda set by the footprint research community andrecommendations has been made to deal with them. The research community already use various metrics to compute the ecological footprint: global hectares, actual hectares and disturbed hectares. The increasing use of input-output technics has also enhanced the localization of the footprint. In this paper all the metrics are used in conjunction with input-output techniques to produce four ecological performance indicators of a local economy taking in account: its global weight on the planet, its degree of dependence on distant ecological ressources, the sustainability of its farming practices, and the quantity of local fertile land not yet used in a bioproductive way. This four performance indicators are then plotted together giving an easy visualizing tool to compare various alternative scenariosBenchmarking ; local ; ecological performance ; footprint accounts

The disconnect between indicators of sustainability and human development

This paper presents an initial review of the theoretical and measurement discussions of sustainability and its relation to human development. As we show in this paper, there is an overall consensus about the importance of sustaining development and well-being over time, but in reality different development paradigms lead to different definitions and measures of sustainability. We review some of those measures, among which the Adjusted Net Savings (a green national accounting measure calculated by the World Bank and rooted in a weak concept of sustainability), the Ecological Footprint (calculated by the Global Footprint Network and rooted in a strong concept of sustainability, where environment is considered a critical resource), and the carbon dioxide emissions (a simple environmental indicator, used in international debate of climate change). Our analysis shows conflicting conclusions when studying the correlations between these indicators of sustainability and existing human development indicators, namely HDI, which emphasizes the need for further analysis to understand what “sustainable human development” means. Nevertheless, as we show here, over time there has been a close link between higher economic performance and energy consumption, which has been mostly based in the use of fossil fuels.sustainability, human development, measurement, energy.

From Ecological Footprint to Ecological Rent: An Economic Indicator for Resource Constraints

This paper takes as its starting point a combination of a (monetary) input-output model with a national Ecological Footprint account for Germany in the spirit of Wiedmann et al. (2006). Footprint as well as biocapacity are dealt with at the industry level. Gross output of each industry and final demand for each industry can then be split into a share that can be reconciled with biocapacity and another share that corresponds to biocapacity overshooting. The Ecological Footprint concept is extended in this study by introducing the additional biophysically productive land necessary for sustaining the given level of economic activity. It is assumed that each industry had to rent the corresponding areas and to apply a given technology in order to make this additional land biophysically productive. This results in a new technology for each industry leading to an increase in costs and prices. The new price level is directly linked to the share of output that corresponds to biocapacity overshooting. Economic indicators can be derived by measuring the income difference brought about by the price increase. This difference corresponds to a Ricardian rent which is due to resource constraints on output growth

Carbon emissions locked - in trade

In recent years there has been a growing concern about the emission trade balance of countries. It is due to the fact that countries with an open economy are active players in the international trade, though trade is not only a major factor in forging a country’s economic structure anymore, but it does contribute to the movement of embodied emissions beyond the country borders. This issue is especially relevant from the carbon accounting policy’s point of view, as it is known that the production-based principle is in effect now in the Kyoto agreement. The study aims at revealing the interdependence of countries on international trade and its environmental impacts, and how the carbon accounting method plays a crucial role in evaluating a country’s environmental performance and its role in the climate mitigation processes. The input-output models are used in the methodology, as they provide an appropriate framework for this kind of environmental accounting; the analysis shows an international comparison of four European countries (Germany, the United Kingdom, the Netherlands, and Hungary) with extended trading activities and carbon emissions. Moving from the production-based approach in the climate policy, to the consumptionperspective principle and allocation [15], it would also help increasing the efficiency of emission reduction targets and the evaluation of the sustainability dimension and its impacts of international trade. The results of the study have shown that there is an importance of distinction between the two emission allocation approaches, both from global and local level point of view
