The elements of Goodrich Petroleum that make it a Buy are presented in a ROTH Capital Partners report.

Municipal solid waste (MSW) landfills, which consist of everyday consumer items, are potential long-term sources of emissions that could threaten the environment and human health if they are not managed carefully after closure. New research has presented a methodology to estimate future emission levels for closed MSW landfills and the impact of different aftercare strategies.

New research has found evidence that a small Marine Protected Area (MPA) in the Mediterranean has the potential to deliver larvae of some fish species to surrounding, non-protected areas. This is one of few studies to investigate this desired role of MPAs and its design could be used to evaluate current and future MPAs elsewhere.

A recent study has assessed the lifecycle environmental impact during the production and use phase of three battery types for plug-in hybrid (PHEV) and full performance battery electric vehicles (BEV). The study indicates that newer lithium-ion (Li-ion) technologies outperform current nickel-metal hydride (NiMH) batteries and identifies processes contributing to 13 environmental impacts

Researchers have developed a new model to assess the health-related external costs arising from air pollution from ten major emission sectors. Applying the model at national and Europe-wide levels, they suggested that the major contributors to costs were industrial power production, agriculture, road traffic and domestic combustion.

The global production, trade and use of goods and services has a significant impact on the environment — and rates of consumption are rising. A new study combines two assessment methods to quantify the impact of European trade on the environment. It finds that, overall, the EU was a net importer of environmental impact from 2000 to 2010, that machinery, equipment and vehicles contributed most to the EU’s export impacts and that the EU’s trade balance (import impact minus export impact) is increasing over time. The two assessment methods complement one another well and could form the basis for future country or region-wide studies, suggest the researchers, by enabling a detailed analysis of individual steps within a product’s trade flow, while also providing a larger picture of the overall process.

As 3D printing, also known as additive manufacturing (AM), begins to replace conventional manufacturing, the environmental impacts of its implementation must be assessed. This study conducted a life cycle assessment (LCA) to investigate the environmental and resource implications of using AM to manufacture the metal parts of an engine in a light distribution truck. In the LCA, the impacts of both present and possible future states of AM technology were compared with current conventional manufacturing. The results suggest that there are potential environmental and resource benefits1 to AM technologies, but that these benefits rely on the achievement of a clean energy source and further technological development.

New research has compared the environmental impact of four alternative methods of water supply in Copenhagen. Results indicated that rain and stormwater harvesting is the most environmentally sound approach, whilst desalination currently has a large environmental impact, mainly due to electricity use. However, if freshwater extraction is included as an impact, the environmental credibility of desalination is improved.

A recent study has compared the environmental impact of a range of building materials. Energy consumption, carbon dioxide emissions and water demand can all be reduced by switching to renewable sources of energy, improving technologies and promoting eco-friendly alternative materials.

A method has been developed to compare how EU Member States have implemented the Energy Performance Buildings Directive. It suggests that implementation varies widely across Europe but that the Czech Republic, Finland, Portugal and Slovakia have kept to the Directive’s aims and guidelines most closely, based on data available in 2009.

New research has assessed the environmental impact of gold production using life cycle assessment and estimated embodied energy and greenhouse gases, embodied water and solid waste burden that each tonne of gold produces, using various processes.

A hacking group has started to flood a dark web hacking marketplace with databases containing a combined total of 73.2 million user records over 11 different companies. [...]

As the media environment changes, the way scientists communicate their work must also evolve. This study explored the effect of public communication on the scientific ‘impact’ of America’s most highly cited nanotechnology researchers. It provides the first evidence that outreach activities, such as speaking to journalists and being mentioned on Twitter, can increase a scientist’s impact.

Sea level rise may cause soils in coastal regions to become more saline. In a recent study, reproduction in soil invertebrates was impaired in soils containing salt levels below the threshold used currently to define saline soils. The authors recommend community-level studies to further investigate the salt concentrations that are harmful to soil organisms.

Researchers have proposed a new indexing scheme to help decision-makers prioritise brownfield sites for redevelopment. The scheme scores potential sites according to socio-economic, smart growth and environmental dimensions. By giving users the flexibility to emphasise some aspects of development as more important than others, it can be adapted for use in different contexts.

There is a growing demand for new settlements in and around urban areas due to social, economic and population factors. However, this can lead to the loss of agricultural land and green spaces that provide essential ecosystem services and contribute to the wellbeing of local people. Several countries, such as the UK and Germany, have attempted to limit the growth of urban areas by encouraging the redevelopment of brownfield sites.

Researchers at the Stowers Institute have established a definitive link between the makeup of the microbiome, the host immune response, and an organism's ability to heal itself.

A recent study compares the effects of organic, ‘natural’ fertilisers, such as compost, with mineral, synthetic fertilisers, such as urea, on N2O emissions from Mediterranean soil. It suggests that there is little difference between the fertilisers, but that pig slurry offers the best overall balance in terms of emissions and crop yield.

A recent EU-supported study has analysed the development of volunteer or ‘rogue’ GM (genetically modified) maize plants in a conventional crop field. It finds that their numbers are low and do not exceed the EU’s threshold of 0.9 per cent for incidental GM content.

A recent study has compared the chemical environmental impacts of using the weed controller glyphosate on glyphosate-tolerant (GT) crops, with the use of other herbicides on non-GT crops. Glyphosate used on GT crops had lower environmental impacts than herbicides used on non-GT crops, but the persistence of AMPA (a break-down product of glyphosate) in soils could be a problem in the future.

The number and impacts of disasters have increased in Europe in the period 1998-2009, a new report by the European Environment Agency (EEA) concludes. The report assesses the frequency of disasters and their impacts on humans, the economy and ecosystems and calls for better integrated risk management across Europe.

The damaging health impacts of some key air pollutants can occur at lower atmospheric concentrations than indicated by the most recent World Health Organization (WHO) Air Quality guidelines, set in 2005 and currently used in Europe. This is according to a new WHO report, which assesses scientific evidence to help inform European air pollution policies.

Exposure to excessive noise is recognised as a major environmental health concern. This Thematic Issue examines the impact of noise on human health and outlines how policy initiatives may limit health effects from noise annoyance - and improve wellbeing.

A recent study suggests that exposure to aircraft noise during the day has a greater impact on cognitive ability in children than sleep-disruption caused by exposure to aircraft noise during the night. Protective policy is therefore likely to be most effective if focused at the school level.

It is difficult to compare estimates of noise exposure across EU Member States because the methods used to produce the data vary between countries. A new study has investigated five methods of estimating noise exposure and identified some of the reasons for variation in the data they produce.

Exposure to aircraft noise at night for more than 20 years could increase the risk of heart disease and stroke, according to research conducted around six European airports. Risk also increased for those constantly exposed to road traffic, but this may have been caused by air pollution rather than noise.

People living close to road, rail and aircraft noise are likely to experience negative health effects. Long-term noise exposure may lead to problems with their heart and circulatory (cardiovascular) system and night-time noise is particularly disruptive of sleep patterns, which in turn may lead to cardiovascular health problems, a review of research into the effects of noise on cardiovascular diseases has found.

While occupational exposure to noise has declined, ‘social’ exposure in the form of personal music players or rock concerts is estimated to have tripled for young people since the 1980s. A new review examines studies that have investigated noise sources, including environmental (e.g. traffic) and social (e.g. via headphones) sources. The review also explores research into the range of health effects beyond hearing impairments, such as annoyance and cardiovascular problems.

Standards for environmental management, such as EMAS and ISO 14001, aim to help organisations become more sustainable, but they have received little evaluation. A new Italian study is the first to quantitatively compare the impacts of these two standards. Its results suggest that EMAS's stipulation that organisations must report their ongoing performance may bring sustained environmental benefits in the longer term.

New insights into the impact of dredging on the environment highlight the distinction between small, frequent deposits of sediments arising from maintenance dredging, and larger one-off capital deposits. Understanding this distinction is crucial for effective licensing and monitoring of dredging.

Environmental impact studies which are conducted early on in the development of wave and tidal-power schemes allow the schemes' technology to be adapted to consider their impacts on marine ecosystems, according to a recent study which reports on a Swedish research wave park.

A recent study in Finland suggests new building regulations will lead to a substantial reduction in the total energy demand and CO2 emissions in new apartment buildings. This could have an impact on the source of energy used for new buildings. In particular, the demand for space heating will fall, which could have an impact on the source of energy used for new buildings.

A new study highlights the environmental impact of beef produced from specialist meat production based on suckler herds, as opposed to that based on the calves of dairy cows. According to the study, beef produced in this way has a greater impact in terms of greenhouse gas (GHG) emissions, acidification and eutrophication potential, and on land use.

The impact of climate change on electricity consumption is important to both adaptation and mitigation policies. New research has estimated that over the next 100 years climate change could cause up to a 20 per cent decrease in demand for electricity for heating in Northern Europe and up to a 20 per cent increase in demand for electricity for cooling in Southern Europe.

A new study assesses the potential impacts of climate change on human health in the Netherlands. The researchers conducted a survey, asking health experts to rate the level of uncertainty attached to different health impacts of climate change, which highlighted heat-related deaths and vector-borne diseases as particularly relevant to climate change adaptation.

When assessing the environmental impacts of new ‘green’ concretes, care should be taken to ensure that a range of impacts are considered, such as ecosystem damage and water depletion, rather than a sole focus on CO2 emissions, a recent study concludes. It demonstrates that cement incorporating industrial by-products performs substantially better than Portland cement when rated across several classifications of environmental impact.

The world’s ocean ecosystems will suffer warming, increased acidity, low oxygen and reduced primary food supply as a result of rising CO2 and this is likely to have dramatic environmental and social impacts, a new study concludes. It predicts that the most vulnerable low-income countries, where 870 million people are dependent on marine ecosystems, would be affected if CO2 emissions are not tackled.

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.

Municipal solid waste (MSW) landfills, which consist of everyday consumer items, are potential long-term sources of emissions that could threaten the environment and human health if they are not managed carefully after closure. New research has presented a methodology to estimate future emission levels for closed MSW landfills and the impact of different aftercare strategies.

A new study has shown that contamination of groundwater by hazardous substances contained in waste liquid from landfill sites – known as leachate - could be significantly reduced by choosing specific types of material to line the landfill reactors.

Life-cycle indicators to monitor selected waste streams' impacts on the environment have been developed by the European Commission’s Joint Research Centre (JRC). These are presented in a recent study which describes a method for analysing waste's impacts using these indicators. The study also reveals the need for better statistics and more detailed categorisation of waste streams to effectively inform decision making in waste management.

Life cycle assessment (LCA) can measure the environmental impact of the different stages of a ship’s life cycle, from design to dismantling. This assessment focused on the impact of recycling the metal parts of a ship and did not consider the crucial impact of the hazardous materials present on board. The results showed that re-use of metals had environmental benefits, but overall these were small compared to the environmental impact of other life cycle stages, such as operation.

A study has evaluated three types of media campaign conducted by a large UK supermarket to encourage shoppers to reduce their food waste. These used social media, an e-newsletter and a print/digital magazine, respectively. Although they all appeared to lead to reductions in food waste to some extent, similar behavioural changes were also seen for customers who had not participated in any of the campaigns.

Researchers have examined environmental and economic impacts of supermarket food waste in a new study. Bread and meat products made the largest contribution to the environmental footprint of the supermarket assessed. Alternative waste strategies, such as using bread waste as animal feed, have the potential to reduce these impacts.

The development of future recycling technologies must be informed by data about products and materials that will enter the waste stream, but such forecasts are subject to a high level of uncertainty. In this study, researchers have proposed a methodology for predicting emerging waste materials, applying it to silicon-based photovoltaic (PV) panels. The findings show that closed-loop recycling — when post-consumer waste is recycled to make new products — of PV panel materials could mitigate up to 0.2% of the annual environmental impact of Flanders1, Belgium, if suitable technology was developed.

Consumers in France, Germany and the USA perceive ‘environmentally friendly’ packaging to be reusable, recyclable and ‘biodegradable’1, finds a new study. These results suggest that producers should emphasise the end-of-life merits of packaging to appeal to consumers’ environmental concerns, and design packaging that is reusable, recyclable and ‘biodegradable’. However, they also indicate a need to raise public awareness of packaging’s true life-cycle environmental impacts, such as those during production and transport, which are greater than consumers generally perceive them to be.
