On étudie la gouvernance des transitions vers des villes plus économes en carbone. On s'interroge sur la diversité de ce que l'on entend par la gouvernance ducarbone dans les villes. On analyse un audit d'initiatives de gouvernance ducarbone dans
les villes australiennes. On suggère quatre programmes gouvernementaux distinctifs. Le paysage émergent de l'Australie en matière de gouvernance urbaine ducarbone reproduit autant les mises en ordre de la gouvernance existants qu'il contient des

Regional accumulations of pedogenic carbonates were examined relative to precipitation, altitude, and temperature. The largest accumulations of pedogenic carbonates were found in calcic soils in warm, arid areas. In the naturally desertified lands
of China, total stored carbon, including carbonatecarbon, is 1,8-fold more than organic carbone alone. The carbon released through land desertification in China may be an important factor affecting changes in concentrations of greenhouse gases worldwide.

Les AA. développent une nouvelle approche basée sur les émissions de carbone basées sur les consommations d’énergie des foyers en Floride. Elles sont ensuite intégrées aux taux de séquestration de carbone de la végétation et modélisées à l’aide de
la télédétection. Les résultats montrent que la Floride assimile les émissions de carbone résidentielles nettes (comprenant les ressources pour la consommation et les transports) et que les sources de carbone sont associées aux densités urbaines et

Capitalizing on the carbon sequestration potential of agroforestry in Germany’s agricultural landscapes : realigning the climate change mitigation and landscape conservation agendas
The paper calls for greater integration of scattered trees into agricultural landscapes, hypothesizing that agroforestry practices effectively store carbon and deliver other important ecosystem services. Several agroforests from the Upper Lusatia
have been selected. Practices of conserving or promoting six agroforest classes are compared with a catalogue of essential properties for becoming effective carbon offset projects. Criteria from mandatory and voluntary carbon markets for carbon
sequestration are then applied. The study concludes that steps towards realization of ‘carbon sequestration projects’ should include collecting empirical evidence regarding the carbon sequestration potential of temperate agroforestry systems.

This paper presented an approach to project the future CO2 emissions from the perspective of optimal economic growth, and applied this model to the cases of China and the United States, whose CO2 emissions together contributed to more than 40
% of the global emissions. The projection results under the balanced and optimal economic growth path reveal that the CO2 emissions will peak in 2029 for China and 2024 for the USA owing to their empirically implied pace of energy efficiency improvement. Moreover

Many of the essays focus on the materiality of carbon : its physical properties and how this affects its enrolment into the global circuits of capital. Many contributions highlight the need to take seriously the biophysical properties of carbon
. These properties may give rise to new governance challenges (in terms of commodification, measurement and exchange) or produce distinct forms of socio-ecological relations. There is a focus on the scalar politics of the new carbon economy and the specific
governance challenges it generates. There are claims of the uneven development that results on the ways in which carbon is commodified.
Samples taken from loess and paleosols were examined for carbonate content. The main results were: 1) the carbonate content measured differed significantly when the samples were analysed jointly with the concretions occuring in them or separately
from these constituents; 2) solubility of different carbonates (calcite, dolomite, aragonite etc.) was found different. This factor also might have influenced the measured total amounts of carbonates.
Carbonate leaching rates in several soils in Switzerland and in the Lake Constance region were calculated and related to landscape development. The leached depth of the soil, the carbonate content and the soil density profile are sensitive to soil
age. A first database of carbonate leaching and its relationship to soil age is presented. A simple relationship between the amount of precipitation and carbonate losses was found.

The AA. measured the carbon budget of 8 sites: 4 restored-revegetated sites, 2 unrestored bare soil control sites, and 2 intact vegetated controls over 2 years (2006-2008). They considered the following flux pathways: dissolved organic carbon (DOC
); particulate organic carbon (POC); dissolved carbon dioxide (CO2); primary productivity; net ecosystem respiration, and methane (CH4). The study shows that unrestored, bare peat sites can have significant carbon losses. Most sites showed improved carbon budgets
(decreased source and/or increased sink of carbon) after restoration; this improvement was mainly in the form of a reduction in the size of the net carbon source, but for one restored site the measured carbon budget after 4 years of restoration was greater
than observed for vegetated controls. Therefore, the carbon sequestration benefit of peatland restoration is evaluated.

This paper reviews the progress of carbon trading in China and examines the involvement of the state and financial sectors. The results show a hierarchical relationship between the state and finance and a clear asymmetry of power in the organization
of China’s carbon markets. It concludes that China has put the market-based policy instrument of carbon trading under a substantial concentration of state power. Also, the findings have important implications for understanding the rise of carbon markets
This article analyses the ecological–economic geographies of globalization in order to demonstrate how regions could be connected with seemingly distant carbon emissions. It shows that emissions from emerging economies such as China might also
but in quantitative research as well. An understanding of the geography of carbon emissions that is adequate to an era of globalization will require theoretical subtlety as much as additional empirical research.

unfolded that the expansion of economic scale is the main driver of the rapid growth of carbon footprint. Thirdly, developing low-carbon economies and low-carbon industries, as well as advocating low-carbon city construction and improving carbon efficiency
would be the primary approaches to inhibit the rapid growth of carbon footprint. Moderately controlling the economic scale and population size would also be required to alleviate carbon footprint.
Based on the energy consumption, integrated with the Top-Down life cycle approach and geographically weighted regression (GWR) model, this paper analyzed the spatial differences and multi-mechanism of carbon footprint in provincial China in 2010
. Firstly, the AA. calculated the amount of carbon footprint of each province using “Top-Down” life cycle approach and found that there were significant differences. Secondly, with the aid of GIS and spatial analysis model (GWR model), this paper had
