This discussion paper questions the idea that ‘greener’ economic growth can achieve the reductions in GHG emissions that are necessary – a point that was also powerfully made by Tim Jackson in his 2009  book Prosperity without Growth: Economics for a finite planet.

This article in the Copenhagen Post covers reactions to the Danish government’s proposal to tax sugar  in a manner similar to last year’s introduction of a saturated fat tax.

This study calculates and maps humanity’s green, blue and grey water footprint at a high spatial resolution. 

Aljazeera video series earthrise takes an upbeat look at ecological, scientific, technological and design projects all around the world, from a farm in Australia growing low impact crops using sea water and solar power, to an ingenious project that has dramatically cut rhino poaching on a South African game reserve.

The CCAFS (Climate Change, Agriculture and Food Security) programme have published a new report that looks at the role and effectiveness of private sector CSR activities in the agricultural sector.

The Scottish Aquaculture Research Forum has published a study on Scottish produced suspended mussels and intertidal oysters. The study considered the cradle-to-gate impacts of the shellfish, from spat collection in the case of mussels, and hatching in the case of oysters, through  growing, harvesting, depuration, and packing ready for dispatch.  To illustrate the carbon impacts of the full life cycle, a scenario is included that,  based on various assumptions, illustrates the potential impacts of distribution, retail, consumption and disposal of the shells. 

This article in Science Daily is based on materials prepared by the French Institut de Recherche pour le Développement (IRD)  It argues that Brazil’s reliance on agricultural exports to drive economic growth is environmentally unsustainable and highlights the link between deforestation for cattle grazing, soy production on cleared land which pushes cattle further into the forest, and the sale of high-value timber.  The article states that government controls introduced from the year 2000 have scaled down deforestation from around 20,000 to 6,000 km² per year, but the threat of an increase in world demand is always just over the horizon, with implications for further deforestation.

The UK dairy sector has published its first report which looks at the carbon footprints of a selection of British dairy farms with a view to establishing a baseline against which progress can be measured.   The study reveals very substantial differences in the GHG footprints expressed as CO2 eq/kg fat corrected milk, of different farms, and also finds that there is more variation between farms, than between production systems.  It also concludes that there is no one variable (eg milk yield, fertiliser use or energy consumption) that accounts for most of the variation between farms.

The Danish EPA has compiled guidance for policy-makers aiming to promote SCP in the food retailing sector. It states that  “Government has an important enabling role to play in using policy levers to support the development of a business case for manufacturers and retailers to produce and deliver more sustainable products.
