Green economy: fix our 'ends' not just our 'means'

While growth remains as our main goal economic and environmental crisis will persist. A green economy requires us to aim at development rather than growth, through the responsible promotion of justice, the common good, and environmental sustainability.

The green economy and sustainable development: an uneasy balance?

The United Nations Conference on Sustainable Development (or Rio+20) was conceived at a time of great concern for the health of the world economy. In this atmosphere ‘green economy’ was chosen as one of two central themes for the conference, building on a burgeoning body of literature on the green economy and growth. This research examines the relationship and influence between the double crisis and the rise of ‘greening’ as part of the solution. The aim is to understand what defines and distinguishes the proposals contained in twenty-four sources on the green economy (including policy documents by international agencies and think tanks, and research papers), and what is the meaning and implication of the rising greening agenda for sustainable development as it enters the 21st century. Through a systematic qualitative analysis of textual material, three categories of discourse that can illuminate the meaning and implication of greening are identified: ‘almost business as usual’, ‘greening’, and ‘all change’. An analysis of their relationship with Dryzek's classification of environmental discourse leads to the identification of three interrelated patterns: (1) scarcity and limits, (2) means and ends, and (3) reductionism and unity—which deepen our understanding of the tensions between emerging propositions. The patterns help explain the meaning and implications of greening for sustainable development, revealing an economisation and polarisation of discourses, the persisting weak interpretation of sustainable development, and a tension between the fixing or shifting of dominant socioeconomic paradigms that underpin its conceptualisation.

Literature Review WM9: Part II - light goods vehicles in urban areas, carried as as part Work Module 1, Green Logistics Project

LGVs are of ever-greater importance in terms of the final delivery of many time-critical, high value goods and are also widely used in industries that provide a wide range of critical support services. There are almost five times as many LGVs as there are HGVs (goods vehicles over 3.5 tonnes gross vehicle weight) currently licensed in Britain. The LGV fleet in Britain is growing at a faster rate than the HGV fleet, and the LGV fleet travels more than twice as many vehicle kilometres each year than the total HGV fleet. LGVs perform a far greater proportion of their total distance travelled in urban areas than HGVs, and consume 25% of the total diesel and 3% of the total petrol used by all motorised road transport vehicles in Britain.

Literature Review WM9: Part I - urban freight transport, carried out as part of Work Module 1, Green Logistics Project

The review illustrates the importance of road movements in goods distribution in urban areas. It highlights the major economic, environmental and social impacts associated with this freight activity and reviews policy options available to those responsible for regulation. A wide range of possible solutions to problems posed by urban freight operations are also covered including approaches related to: consolidation, facilities, vehicle design, information capture and utilisation, and non-road modes.

Characterization of two immunomodulating homogalacturonan pectins from green tea

Two natural homogalacturonan (HG) pectins (MW ca. 20 kDa) were isolated from green tea based on their immunomodulatory activity. The crude tea polysaccharides (TPS1 and TPS2) were obtained from green tea leaves by hot water extraction and followed by 40% and 70% ethanol precipitation, respectively. Two homogenous water soluble polysaccharides (TPS1-2a and TPS1-2b) were obtained from TPS1 after purification with gel permeation, which gave a higher phagocytic effect than TPS2. A combination of composition, methylation and configuration analyses, as well as NMR (nuclear magnetic resonance) spectroscopy revealed that TPS1-2a and TPS1-2b were homogalacturonan (HG) pectins consisting of a backbone of 1,4-linked α-d-galacturonic acid (GalA) residues with 28.4% and 26.1% of carboxyl groups as methyl ester, respectively. The immunological assay results demonstrated that TPS1-2, which consisted mainly of HG pectins, showed phagocytosis-enhancing activity in HL-60 cells.

Laccase bio-grafting a versatile modification tool from green chemistry technologies

Today more than 99% of plastics are petroleum-based because of availability and cost of the raw material. The durability of these disposed plastics contributes to the environmental problems as waste and their persistence in the environment causes deleterious effects on the ecosystem. Environmental pollution awareness and the demand for green technology have drawn considerable attention of both academia and industry into biodegradable polymers. In this regard green chemistry technology has the potential to provide solution to this problematic issue. Laccase bio-grafting has recently been the focus of green chemistry technologies due to the growing environmental concerns, legal restrictions and increasing availability of scientific knowledge. In the last several years, research covering various applications of laccases has been increased rapidly particularly in the field of grafting. In principle, laccase-assisted graft co-polymerization may impart a variety of new functionalities to a polymer. The modified polymers through grafting have a bright future and their development is practically boundless. In present work, novel biodegradable graft copolymers combining the advantages of bacterial cellulose backbone and PHB side chains will be prepared by introducing enzymatic grafting technique. The present research will be a first step in the biopolymer modification. To date no report has been found in literature explaining the enzymatic grafting of PHAs. The technique would also provide an efficient modulation approach to improve the biodegradability and biocompatibility of the graft copolymer. The newly grafted copolymers will exhibit unique functionalities with wider range of potential applications mainly in tissue engineering, biosensors, pharmaceutical industry (drug delivery systems) and bio-plastics.

A repeated measures experiment of green exercise to improve self-esteem in UK school children

Exercising in natural, green environments creates greater improvements in adult's self-esteem than exercise undertaken in urban or indoor settings. No comparable data are available for children. The aim of this study was to determine whether so called ‘green exercise’ affected changes in self-esteem; enjoyment and perceived exertion in children differently to urban exercise. We assessed cardiorespiratory fitness (20 m shuttle-run) and self-reported physical activity (PAQ-A) in 11 and 12 year olds (n = 75). Each pupil completed two 1.5 mile timed runs, one in an urban and another in a rural environment. Trials were completed one week apart during scheduled physical education lessons allocated using a repeated measures design. Self-esteem was measured before and after each trial, ratings of perceived exertion (RPE) and enjoyment were assessed after completing each trial. We found a significant main effect (F (1,74), = 12.2, p<0.001), for the increase in self-esteem following exercise but there was no condition by exercise interaction (F (1,74), = 0.13, p = 0.72). There were no significant differences in perceived exertion or enjoyment between conditions. There was a negative correlation (r = −0.26, p = 0.04) between habitual physical activity and RPE during the control condition, which was not evident in the green exercise condition (r = −0.07, p = 0.55). Contrary to previous studies in adults, green exercise did not produce significantly greater increases in self-esteem than the urban exercise condition. Green exercise was enjoyed more equally by children with differing levels of habitual physical activity and has the potential to engage less active children in exercise.
