A new study suggests that, although the global terrestrial carbon sink remained relatively stable from 1990 to 2007, the effects of tropical forests were virtually neutral because CO2 emissions from deforestation offset their carbon sink.

Locally managed carbon budgets for housing and transport could be highly effective in reducing greenhouse gas (GHG) emissions, according to researchers. They have suggested a policy framework with standardised methods to monitor city carbon budgets with local flexibility for remaining within these budgets.

According to a new study, an average UK household could reduce its greenhouse gas (GHG) emissions by around 37 per cent through lifestyle changes whilst maintaining an acceptable standard of living.

New research suggests that reducing the value of clean development mechanism (CDM) emission credits according to a country’s wealth and their emissions could encourage advanced developing nations, such as China and India, to leave the CDM, but would not necessarily accelerate CDM projects in the least developed nations.

International agricultural development must broaden its scope to address food security issues, according to a new study. The research recommends removing boundaries between sectors to allow agricultural policy to account for impacts of macroeconomic trends, climate change and links between malnutrition and infectious disease.

China does not export cars to Europe, yet it has adopted the Euro emissions standard for vehicles. A recent study argues this is because international standards can encourage foreign investors to share advanced technical knowledge with companies in developing and emerging economies – thus bringing a package of environmental and economic benefits. In China’s case, its car industry is now better prepared for future trade in a global market, thanks to this strategy.

Climate change objectives are now featured in a wide range of policies, including the European Rural Development Programme, which promotes sustainable agricultural interventions. This study describes the net greenhouse gas emissions for these interventions across Europe. The findings could help policymakers to better meet multiple social, economic and environmental objectives, although the authors say a broader perspective may be needed to determine the overall benefit of interventions.

Research assessments should focus more on engagement processes and less on impacts and outcomes, a new study suggests. The authors examined researchers’ intended impacts and motivational factors, and stated that a change in research evaluation methods, together with better direction from university managers, could help incentivise knowledge exchange and engagement between departments and non-academic entities.

The concepts of instrumental value (protecting nature for humans’ sake) and intrinsic value (protecting nature for nature’s sake) are fundamental to environmental policy. This paper — based on a literature review and critical analysis — argues that using these concepts alone overlooks important concerns for the environment. The authors recommend also considering relational values, which derive from the relationships between people and nature.

The top 10 environmental priorities for EU inland ports have been identified in a recent survey. A port’s relationship with the local community was the top environmental issue, followed by concerns over air and water quality. The survey provides the first benchmark of the environmental performance of inland ports, against which progress in their environmental management can be measured in the future.

Landfill taxes and ‘enhanced waste management’ practices have been introduced to reduce the amount of waste that goes to landfill and to convert waste into useful products. This study investigated the interplay of these two policy options in Belgium, generating findings that could help Europe move towards a resource-efficient, circular economy.

A new international report has investigated the impact of water scarcity and other water-related issues on some of the world’s largest companies in water-intensive industries. Nearly 40 per cent of companies surveyed are already experiencing water problems and nearly 90 per cent have developed water policies, strategies and plans.

Marine diesel contains sulphur compounds, which generate sulphur oxide (SOx) pollution and acid rain. Ships can use mitigating technologies to reduce their SOx emissions, but these can also have a negative environmental impact. The International Maritime Organization (IMO) introduced stringent legislation to control these, aspects of which are incorporated into EU policy. This study examined the implications of the IMO’s policy and recommends a number of design solutions to help ships comply.

The impact that national energy sectors have on international freshwater resources has been demonstrated in the first global study of its kind. The analysis of 129 countries showed differences between countries and sectors in their reliance on international freshwater resources. For example, although the petroleum industries of North America and China are similar in magnitude, the North American industry consumes three times as much international freshwater. Demands from economically developed countries on less economically developed countries, which may have pre-existing water-scarcity issues, compound these problems and complicate the creation of policies that ensure both water and energy security.

Reusing waste water for non-drinking uses in decentralised plumbing networks may improve the efficiency of water supply in urban areas, a new study has found. Modelling this approach in San Francisco, researchers found that, depending on the local geography, a decentralised water supply could lead to energy savings and reductions in greenhouse gas emissions from water treatment of around 30%. Improvements in emerging water-treatment technologies are likely to lead to further savings, which could help increase the efficiency of urban water supply.

NITES, said that this went against the government guidelines of not firing people or cutting salaries during the pandemic.

A UK solar park has been found to change the local microclimate, reports recently published research. Moreover, the microclimate coupled with management activities had an impact on greenhouse gas emissions and plant-community diversity and productivity under the solar panels. The study’s authors say their research provides a starting point for considering how to improve solar-park design in order to deliver co-benefits for biodiversity and farming, and minimise any negative environmental effects.

A new study suggests that the energy sources used in chemical production contribute significantly to environmental damage in developed countries. The researchers recommend increasing the efficient use of heat and electricity, in addition to reducing direct emissions of harmful pollutants, to dramatically improve the environmental impact of the chemical industry.

A recent study has considered the levels at which active pharmaceutical ingredient (API) residues are safe when released into water bodies from drug manufacturing plants. It proposes that environmental reference concentrations and maximum tolerable concentrations are adopted for each API.

Calculating the costs of nitrous oxide (N2O) emissions to society as well as business is vital to understand the true economic gains of reducing N2O emissions, new research suggests. Increasing nitrogen use efficiency by 20% by 2020 could bring global annual benefits to the climate, health and environment worth US $160 (€118) billion, the researchers conclude.

The emissions of two perfluoroalkyl acids (PFAAs) into the Danube River Basin have been estimated in a test of four different hypotheses regarding the factors affecting those emissions. The results were used to simulate water concentrations for comparison with measured data. The researchers found that incorporating wastewater treatment information and wealth distribution alongside population data can improve the accuracy of emissions estimates.

The Alang shipbreaking yards in India recycle almost half of all end-of-life ships worldwide. The major activity at the yards is plate-cutting, used to recover steel from ships. This process consumes nearly 29 kg of oxygen and 7 kg of liquefied petroleum gas (LPG) and emits almost 22 kg of CO2 per 1 km-long cut with a 1 mm depth. This study reveals the carbon footprint and resources consumed in the cutting of steel plates. The method used to derive these findings could be adapted to ship dismantling yards worldwide.

The pathways for removal of dissolved phosphorus within biofiltration systems have been examined in a new study. Over 95% of phosphorus was removed over the study period, with the majority of phosphorus stored within plants. The researchers say the findings demonstrate the value of using suitable plant species within biofiltration systems to treat polluted water.

Advances in nanotechnology mean that a rapidly increasing number of products are being produced using engineered nanomaterials, for example, nano-enabled thermoplastics. Many of these nano-enabled products are destined to reach their end-of-life through waste incineration or accidental fire. Now, an original study has revealed that the presence of nanofiller in thermoplastics significantly enhances both the concentration and toxicity of polycyclic aromatic hydrocarbons (PAHs) produced during thermal decomposition at the product’s end- of-life, resulting in concentrations of total PAHs and more toxic PAHs that are up to eight times higher than those found in pure (non nano-enabled) thermoplastics. This finding has significant environmental health implications.

A new liquid has been designed to selectively capture sulphur dioxide emissions, one of the primary causes of acid rain. The capture process is reversible so the sulphur dioxide can be released at a later stage. This means, for example, that sulphur dioxide could be captured from power plants and reused later in other industrial processes.

Methane gas emissions could have a larger warming effect on climate than has been previously thought. A recent study has found that the interactions between greenhouse gas (GHG) emissions and aerosols in the atmosphere can change the impact of various emissions, and that mitigation policies should take these effects into account.

According to new research, emissions of anthropogenic nitrous oxide (N2O) are now causing more damage to the ozone layer than those of any controlled ozone depleting substance and this is projected to remain the case for the rest of this century. The study suggests that limiting N2O emissions could help both the recovery of the ozone layer and tackle climate change.

EU-supported research has established a new model to calculate air pollution emissions from ships. Its calculations could create a database that lists emissions per ship type and size as well as by country.

A new tool used to investigate exhaust emissions of marine vessels has been developed and applied to shipping in the Baltic Sea.

Large benefits can be achieved for society by reducing global emissions of mercury. Global savings of US$1.8-2.2 billion (€1.3-1.6 billion) can be made by reducing damage to IQ alone, according to recent research.

New research has estimated the global footprint of emissions from commercial aircraft. In 2006 nearly 190 million tonnes of fuel were burnt and 162 million tonnes of carbon from CO2 were emitted. The vast majority of the fuel was burned in the Northern hemisphere and half the emissions were over the US, Europe and East Asia.

A recent assessment suggests that reducing black carbon emissions, produced by burning carbon-based materials, would prevent millions of premature deaths in developing countries as well as helping meet climate change mitigation targets.

Existing technologies could reduce emissions of CO2 and air pollutants from land transport by almost a third. But, reductions will not be delivered through markets alone, according to a recent assessment, particularly for CO2. The researchers argue that strong policy interventions will be essential to mitigating climate change caused by emissions from land transport.

Environmental policy makers increasingly rely on computer models to test traffic policies. Researchers have investigated the impact of reducing speed limits on traffic emissions using two different models, but the models produced some contradictory results. The researchers therefore warn policy makers to interpret model results very carefully and to avoid relying on simple 'macroscopic' models.

Agriculture is a significant source of greenhouse gas (GHG) emissions. Researchers have developed a framework for estimating emissions of methane and nitrous oxides from agriculture, by updating the International Panel on Climate Change (IPCC) approach, which captures more detail about differences between locations.

The nitrogen dioxides (NOX) and carbon dioxide (CO2) emissions of some light-duty petrol and diesel vehicles are higher during on-road driving than during standard laboratory tests, according to a new study. This means that in normal on-road driving, light-duty vehicles, which include passenger cars and light commercial vehicles, may exceed European emissions limits and could be having a greater impact on urban air quality than previously thought.

There is a growing body of scientific research into the health benefits of urban forests, such as improving air quality and providing recreational space. However, new research challenges the assumption that their overall impact on quality of life is always positive and land planners need to take into account ecosystem disservices as well as services, say the researchers.

Recently adopted EU waste legislation and its implementation at national level could have a significant effect on some countries’ emission loads for municipal solid waste incinerators, according to a recent study. The study suggests that the effects of increasing incineration over the next decade would be most profound for countries where incineration is currently only used on a small scale.

Pollen allergy is a common cause of allergic respiratory diseases such as hay fever and asthma. A recent continent-wide study suggests that rising carbon dioxide (CO2) emissions over the last 30 years may be increasing pollen counts especially in European cities, which could have serious consequences for public health.

To reduce air pollution levels in harbours, EU Directive 2005/33/EC requires all anchored ships to use fuels with low sulphur content. A recent study of air quality in Mediterranean harbours shows that levels of sulphur dioxide have decreased significantly since the Directive was implemented in 2010.

Low emission zones (LEZs) that restrict old vehicles in city centres may need implementation in combination with other traffic policies to have greater impacts on air quality, according to new research. A study that measured emission levels before and after the introduction of LEZs in five Dutch cities indicated that air pollution concentrations were reduced but not to a statistically significant level.

More Europeans are driving diesel cars, with important implications for vehicle emissions. A new study suggests that diesel cars may emit nitrogen oxides (NOx) at levels far higher than emissions standards, even when considering the newest generation of diesel cars. Part of the problem is that tests of vehicle emissions in the laboratory do not accurately reflect on-road emissions.

A recent study suggests that mercury deposited from the atmosphere is the main source of mercury pollution in the open oceans. Curbing mercury emissions will slowly lead to a decrease in contaminated fish, as eaten by humans, within a few years to decades after the cuts have been made, the researchers suggest.

Low emissions zones (LEZs) can substantially reduce local levels of traffic-based air pollution, a new study has shown. Monitoring air pollution in Munich, Germany, researchers found that particulate matter from traffic sources dropped by 60% after implementation of an LEZ.

Strong acids formed from shipping emissions can produce seasonal ‘hot spots’ of ocean acidification, a recent study finds. These hot spots, in ocean areas close to busy shipping lanes, could have negative effects on local marine ecology and commercially farmed seafood species.

Low emission zones (LEZs), which restrict access for high emission vehicles, have proven to be a successful way to improve air quality in line with EU regulations. An analysis of London’s LEZ has revealed discernible reductions in air pollution levels five years after implementation.
