GHG policy should cover 'upstream' electric vehicle emissions

Regulators should establish a process to consider the full lifecycle greenhouse gas (GHG) emissions of electric vehicles, according to a new US study. This would help ensure that vehicle emissions regulations are placed on a sound scientific basis, manufacturers continue to improve the efficiency of electric vehicles, and the full benefit of regulations to limit GHG emissions from vehicles are realised, say the researchers.

Counteracting the urban heat island effect with effective planning

Climate change is likely to exacerbate the urban heat island (UHI) effect. A new study has therefore examined possible climate change adaptation measures that can alleviate the UHI effect and illustrated how these strategies can be practically applied. While the study provides real-life examples to demonstrate how the measures can be used, it does not include any quantitative assessment of their impacts.

Seagrass decline releasing large quantities of carbon

Grasses growing at the bottom of our oceans lock away large quantities of ‘blue carbon’, according to a new study. The results suggest that the soil that seagrass grows on is capable of storing more carbon than soils on land and as a result of the current global decline in seagrass, vast stores of carbon may be being released into the ocean and atmosphere.

Public health risks of hot Mediterranean summers vary by region

Elderly people are at particular risk from the damaging health effects of hot summers in European Mediterranean cities, such as Athens, Barcelona and Lisbon, but in North African and Middle-Eastern Mediterranean cities, such as Tunis and Tel-Aviv, younger people are more vulnerable, a recent study concludes. This is particularly concerning, the researchers suggest, given the insufficient resources available to deal with this public health problem in some countries.

Mediterranean land degradation threatens food security

Climate change, tourism and population growth are all accelerating land degradation in the Mediterranean region, according to recent research. This can have severe impacts: the amount of available agricultural land per capita in the region could have dropped by half by 2020, compared with 1961, the study estimates. This article was updated 6.11.14 to correct an error in the valuation of ecosystem services provided by Mediterranean coastal wetlands.

Decommissioning is a significant part of nuclear power’s GHG impact

The greenhouse gas (GHG) emissions produced during the decommissioning phase of nuclear power plants may have been underestimated in previous assessments, new research suggests. The study estimated that the decommissioning process for a German plant resulted in 1 651 265 tonnes of CO2 (or equivalent) emissions, or 0.825 tonnes of CO2 equivalent per tonne of waste. While the researchers acknowledge that impact is highly dependent on the unique characteristics of each decommissioning project, these results raise questions as to whether this phase has been accurately assessed in earlier research.

Screening soil moisture conditions reveals an increased risk of drought in a Swedish drainage basin

The risk of drought in the Norrström drainage basin, Sweden, increased during the 20th century, a new study has found. As the frequency of the dry periods increased, less water was available in the landscape for agriculture and for the resupply of groundwater — despite an increase in precipitation in the area over the same period. The researchers reached this conclusion after screening soil moisture conditions in the basin over the course of the century.

Ignoring flood risks leads to increasing losses: assessment should include climate change, land use and economic development

Floods are devastating natural hazards, which can cause loss of life and substantial damage to buildings and other infrastructure. Assessing future flood risk is complicated by the influence of climate change, land-use change and economic development in an area. A study on an Alpine valley suggests that land- use change and urbanisation will affect future flood risk by 2030 more than climate change, but risks can be reduced by adopting low-cost adaptation strategies, such as building restrictions in flood-prone areas and residents taking their own precautions against flooding.

Green buildings: researchers call for fuller environmental assessment

Over half of a low-energy building’s environmental impact occurred before it was even occupied, a new case study from Italy calculates. The researchers recommend expanding the environmental assessment of buildings from just the operational stage of a building’s life, when it is in use, to include production and transport of materials, construction activities and building maintenance. A wide range of environmental impacts should also be considered, they argue, and not just energy use.
