Big brand sustainability: Governance prospects and environmental limits     

Peter Dauvergne  Jane Lister 《Global Environmental Change》2012,22(1):36-45

This article introduces and evaluates the implications for global environmental change of the rising power and authority of big brand companies as global environmental governors. Contributing to the private governance literature and, in particular, addressing the gap in this research with respect to the political implications of individual firm ‘buyer power’, the article provides evidence and analysis of how big brand sustainability is altering the power relations within global supply chains, and the governance prospects and limits of this trend. The authors argue that recent brand company efforts through their global supply chains, while still a long way off from their goals, are achieving environmental gains in product design and production. Yet, these advances are also fundamentally limited. Total environmental impacts of consumption are increasing as brand companies leverage corporate sustainability for competitive advantage, business growth, and increased sales. Big brand sustainability, while important, will not on its own resolve the problems of global environmental change. In conclusion, the article highlights the importance of a co-regulatory governance approach that includes stronger state regulations, sustained advocacy, more responsible individual consumerism, and tougher international legal constraints to go beyond the business gains from big brand sustainability to achieve more transformational, ‘absolute’ global environmental progress.  相似文献

Structure of the Mt Isa region from seismic ambient noise tomography     

E. Saygin  H. McQUEEN  L. J. Hutton  B. L. N. Kennett  G. Lister 《Australian Journal of Earth Sciences》2013,60(6-7):707-718

We use seismic tomography, exploiting group velocities derived from ambient noise, to delineate the crustal structure beneath Mt Isa and the surrounding blocks and basins. The depth extent of the blocks can be traced into the mid-crust and the spatial extent of the associated velocity anomalies mapped over an area of approximately 500 km by 500 km. The Proterozoic Mt Isa block is imaged as a region of elevated seismic velocities comparable to the Yilgarn craton in Western Australia, while the surrounding basins have relatively low velocities. Seismic velocity anomalies display correlations with the regional Bouguer gravity data and with high crustal temperatures in the region. There are a number of isolated low-velocity anomalies under the Millungera basin that suggest either previously unknown thermal anomalies or zones with high permeability, which can also produce lowered velocities.  相似文献   

Highly retentive core domains in K-feldspar and their implications for 40Ar/39Ar thermochronology illustrated by determining the cooling curve for the Capoas Granite,Palawan, The Philippines     

M. A. Forster  R. Armstrong  B. Kohn  G. S. Lister  M. A. Cottam  S. Suggate 《Australian Journal of Earth Sciences》2013,60(7):883-902

K-feldspar from the late Miocene Capoas Granite on Palawan in The Philippines appears to contain highly retentive diffusion domains that are closed to argon diffusion at near-solidus temperatures during cooling of this ～7 km-diameter pluton. This is an important result, for K-feldspar is commonly considered not retentive in terms of its ability to retain argon. Closure temperatures for argon diffusion in K-feldspars are routinely claimed to be in the range ～150–400°C but the release of ³⁹Ar from irradiated K-feldspar during furnace step-heating experiments in vacuo yields Arrhenius data that imply the existence of highly retentive core domains, with inferred closure temperatures that can exceed ～500–700°C. These high closure temperatures from the Capoas Granite K-feldspar are consistent with the coincidence of ⁴⁰Ar/³⁹Ar ages with U–Pb zircon ages at ca 13.5 ± 0.2 Ma. The cooling rate then accelerated, but the rate of change had considerably slowed by ca 12 Ma. Low-temperature (U–Th)/He thermochronology shows that the cooling rate once again accelerated at ca 11 Ma, perhaps owing to renewed tectonic activity.  相似文献   

Geochemical mapping using stream sediments in west-central Nigeria: Implications for environmental studies and mineral exploration in West Africa

This paper provides an overview of regional geochemical mapping using stream sediments from central and south-western Nigeria. A total of 1569 stream sediment samples were collected and 54 major and trace elements determined by ICP-MS and Au, Pd and Pt by fire assay. Multivariate statistical techniques (e.g., correlation analysis and principal factor analysis) were used to explore the data, following appropriate data transformation, to understand the data structure, investigate underlying processes controlling spatial geochemical variability and identify element associations. Major geochemical variations are controlled by source geology and provenance, as well as chemical weathering and winnowing processes, more subtle variations are a result of land use and contamination from anthropogenic activity.  相似文献
