People exposed to fine particle (PM2.5) and ozone pollution are at increased risk of suffering out-of-hospital cardiac arrests, according to a recent Finnish study. Cardiac arrest is more likely within 24 hours after exposure to PM2.5 and up to several days after exposure to ozone.

Recent research into the impact of different levels of noise on 75 volunteers reveals that disturbed sleep caused by night-time aircraft noise can damage blood vessels and increase the levels of stress hormones. As these physical changes are potential pathways to high blood pressure, heart and circulatory disease over the long term, reducing night-time aircraft noise is important for preventing cardiovascular disease in people living near airports.

Upland peat soils provide a substantial carbon sink if managed properly, according to new research. A study of a peatland area in the UK indicated that it could potentially store approximately 160,000 tonnes of CO2 per year.

Phrases that combine 'carbon' with other words, such as 'carbon finance' or 'carbon footprint', can provide insight into how climate change issues are communicated. A new study explored online use of these so-called 'carbon compounds' and indicated that they form three clusters focused on finance, lifestyle and attitudes.

The world’s soils have the potential to store about 3000 megatonnes of carbon per year by the end of the 21st century, according to a new study. It suggests that restoring carbon to cropland and peat soils through practices such as afforestation and no-till farming could help solve global problems of food insecurity and climate change.

Scientists have calculated carbon budgets for croplands in Europe, based on field measurements from nine sites across Europe. They found that significant soil carbon losses occurred from cropping even though some farmers used measures to enhance carbon-sequestration. These results may challenge findings from some other modelling studies if they turn out to be typical for all EU croplands.

Land cleared in the tropics loses nearly twice as much carbon and produces less than half the annual crop yield as land in temperate zones, according to researchers. Their analysis of the trade-off between crop production and the loss of carbon stored in vegetation highlights the need to target reforestation in the tropics.

The actual carbon footprint of products and services can differ considerably according to how energy used to manufacture the product was generated – for example, whether it was generated by fossil fuel or renewable sources. A recent US study has therefore recommended that differences in regional power supply should be acknowledged by life cycle assessments of products and services.

A new study has combined measurements of carbon dioxide (CO2) fluxes with estimates of other greenhouse gas (GHG) emissions from farming operations for 15 European crop sites over several years. It estimated that the sites lost on average 138g of carbon per m2 per year. The total GHG balance (including non-CO2 emissions) was equivalent to an average carbon loss of 203g of carbon per m2 per year.

Although the public are largely aware of climate change, their understanding of how they produce and manage carbon is generally not sufficient to lead to changes in behaviour and lifestyle, according to a recent study. The researchers therefore recommend policy action to increase the ‘carbon capability’ of the general public.

Urban vegetation could have been overlooked as valuable above-ground carbon storage, according to researchers. They estimated that 231,521 tonnes of carbon were stored in above-ground vegetation in a UK city, the majority of which (97 per cent) in trees. This was 10 times the amount estimated from national figures for the same city area.

The greenhouse gas emissions from the construction of new houses are so high that they exceed the emissions from three decades of use, a Finnish study has found. The research is based on houses complying with recently introduced, energy efficient building regulations. According to the authors, as buildings become more efficient this ‘carbon spike’ associated with construction is more important than has been suggested by previous studies.

Permafrost and wetlands in high latitudes could switch from carbon sink to carbon source by the end of the century, according to a recent study. Using a model of terrestrial ecosystems that showed how carbon is stored and released in soils at high latitudes, researchers revealed that climate change could cause these soils to release much more carbon than previously predicted.

Extreme events, such as droughts and prolonged dry spells, under climate change could increase the water repellency of soils, according to a recent study. In the long-term, this could reduce the capacity of soils to sequester carbon.

A recent study from Finland on the carbon footprint of food can help producers and consumers make choices that lower the food chain’s impact on climate change, by highlighting hotspots in the food chain for improvement and revealing food’s overall impact.

The majority of respondents to a UK survey would like to see labels explaining the carbon footprint of the food they buy. 72% of the supermarket shoppers questioned were in favour of carbon labels on food. The survey also found that 42% had changed their shopping habits in the last 10 years in response to environmental concerns.

A new study has explored how cities can create a low carbon future by presenting an approach to stakeholder engagement that develops scenarios of an ideal city. Rather than projecting towards a low carbon target for the future, the study suggests that ‘backcasting’ to the present day from these scenarios may provide a useful goal-orientated approach to environmental planning in cities.

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.

Vegetated coastal ecosystems, such as mangroves, marshes and seagrasses, are an important carbon sink and their destruction increases greenhouse gas (GHG) emissions. A new study estimates that 0.15-1.02 Pg (petagrams) of CO2 are being released annually from degradation of these valuable ecosystems, resulting in economic losses of US$6-42 billion (€4.68 to 32.81 billion) per year.

Periods of slow growth observed in coral reefs in the Caribbean are caused by aerosols in the air from pollution and volcanic activity, recent research suggests. Aerosols cause cooler sea surface temperatures and reduce the amount of sunlight reaching the coral, both of which slow coral growth.

Despite better public transport and more energy-efficient housing, city dwellers have a larger carbon footprint than those in rural areas, according to a recent Finnish study. This is partly explained by the phenomenon of ‘parallel consumption’ in which people extend their living space by using services that the home also provides.

Despite their general absence from climate policy discussions, the world’s mountain grasslands and shrublands (MGSs) store between 60.5 and 82.8 billion metric tonnes of carbon, a new study estimates - more than three times that of ocean and coastal ecosystems. This research, which is the first to provide a global inventory of carbon stored in MGSs, argues that these ecosystems should be accounted for in climate policy.

Soil and plants store around 5% of the world’s carbon, but carbon storage in some soils is in decline. Recent research has found that climate change accounted for 9–22% of carbon declines in organic soils in semi-natural habitats throughout England and Wales from 1978–2003. The researchers say monitoring soils rich in carbon should be a priority to ensure that more carbon is not released to reinforce climate change.

Huge amounts of soil carbon have been discovered up to 1 metre below grassland in a recent UK study. Yet most carbon inventories do not assess soil deeper than 30cm. Furthermore, this research suggests that intensive management of grassland, involving high rates of fertiliser use and livestock grazing, may deplete carbon at these depths.

Researchers have proposed a global roadmap for decarbonisation over the coming decades. The roadmap is based on the idea of a simple heuristic, described by the researchers as ‘carbon law’, of halving carbon dioxide (CO2) emissions every decade from 2020 to 2050. The researchers say that, if combined with the development of new technologies and efforts to reduce CO2 emissions from land use, this target could lead to a carbon-neutral global economy by 2050.

Rapidly rising sales of electronic goods could cause huge amounts of hazardous electronic waste (e-waste) to build up in developing countries over the next 10 years, a new study has concluded. Prompt action is needed to ensure e-waste is properly managed in emerging economies to protect the environment and human health.

The carbon footprint of food waste should be taken into account alongside the the weight of food wasted, says a new study. The research examined three years of food waste data from six branches of a Swedish supermarket and calculated the waste’s carbon footprint. On the basis of their footprint, key products that could be targeted for waste reduction include beef mince, meatballs and cream, the results suggest.

A recent study has assessed some of the environmental impacts of the production of batteries used with low carbon systems, such as photovoltaic cells and wind turbines. The results indicate that lithium-based batteries have the most significant impact, in terms of metal depletion and greenhouse gas (GHG) emissions, but more complete data are needed on possible toxic impacts to conduct a full comparison between batteries.

Power plants are a major source of CO2 emissions and contributor to global warming. This study reports on a portable technology to remove CO2 from their combustion exhaust gases. Pilot testing on a coal burning plant in Poland captured thousands of kilograms of CO2 per day. This could be a viable future means of mitigating CO2 emissions from the power generation sector.

Storing atmospheric carbon dioxide (CO2) has the potential to mitigate the impacts of changes in climate. Researchers have now developed a way to inject CO2 into volcanic rock, and tested it in Iceland. Over 95% of the injected CO2 was mineralised (converted into a solid) within two years, instead of taking centuries or millennia as previously anticipated. The technique demonstrates potential for the permanent and safe storage of CO2 within basaltic rocks.

A new study provides clues as to which innovative low-carbon technologies will successfully get onto the market quickly. The historical analysis of 16 energy technologies — from steam engines to wind power — found that the average length of a product’s ‘formative phase’ is 22 years. This important period of innovation in a technology’s development is shorter for products which do not need extensive new infrastructure or changes to user behaviour. The findings could help policymakers identify new technologies that can be deployed more rapidly to meet short-term environmental targets.

The Canary Islands have the potential to become carbon neutral by 2050, a new study indicates. This could be achieved by shifting to a 100% renewable energy supply, improving energy efficiency and building new grid connections between islands. Energy solutions for small island regions, such as the Canaries, could act as role models for larger systems, as well as similar islands, the researchers suggest.

In-depth soil information is increasingly required to achieve an array of environmental and economic goals. In particular, accurate estimates of soil carbon stocks are necessary to guide land-management practices and climate- related policymaking. To help meet this need, Australian scientists have developed a new sensing method to analyse cylindrical soil samples (soil cores), known as the Soil Condition ANalysis System (SCANS). By integrating a novel automated soil- core sensing system (CSS) with advanced statistical analytics and modelling, the SCANS provides a level of detail that is difficult to achieve with existing alternatives. SCANS is not only rapid, accurate and inexpensive1, but is likely to be a useful tool for farmers, land managers and policymakers, as the improved assessment of soil functions, structures and carbon stocks will facilitate more informed, sustainable decision-making.

Indium, a unique metal, is in short supply worldwide and is not recycled at the end of its life (EoL). Indium is used in a wide range of technologies, causing regions across the world that are reliant on its import — such as Europe — to be concerned about security of supply. Primary sources of indium are thought to be sufficient for medium-term needs, but with growing demand comes growing concern over long-term supply. A new study has conducted a material flow analysis and examined secondary sources of indium within European ‘urban mines’ and in-use stocks (IUS) of indium products, identifying these as potential sources of 500 tonnes of indium — if it were recycled at EoL.

In an interview with ETCIO, Vikas Varma, Chief Operating Officer, South Asia, Mastercard talks about how the company’s AI-driven secured contactless payment initiatives have helped them prevent any business losses during the crisis.

The rental car service has tweaked its model to support emergency services during the lockdown and is gearing up its IT infrastructure for the post-Covid surge in demand.

While energy-efficiency gains are needed to lower Europe’s greenhouse gas emissions, low-carbon technologies are also crucial if we are to meet ambitious EU emissions targets in the long term, new comparative research concludes.

Speed control, road traction, wipers when it rains, maintaining safe distances, collision avoidance, and lane change are some of the prominent features.

In the country, autonomous mobility will probably mean robotic tractors rather than robotic cars, and if tractor maker Escorts has its way, they could get here sooner than thought.

New research has compared life cycle environmental impacts of new petrol and diesel cars and highlighted options for improvement. It indicates that the greatest improvements are achievable through more efficient power trains and lightweight cars. However, these technological solutions come at a financial cost whereas other improvement options, such as behavioural changes, provide a win-win solution.

A ‘feebate’ can be an effective policy option to aid the transition to a more environmentally-friendly transport system, a UK study suggests. This combination of fees and rebates can increase the take-up of low-carbon cars, the researchers argue, which leads to reduced life cycle greenhouse gas (GHG) emissions.

Travelling by coach or train has a lower impact on the climate than travelling by air or car, but using a small diesel car to carry several passengers can have similarly low impacts per person, new research suggests. Air travel is the worst form of transport, in terms of global warming impact, the researchers found, but the average percentage occupancy of a mode of transport significantly affects the impact per passenger.

The promotion of diesel-fuelled cars in Europe may not have had the beneficial environmental effects that were expected, research suggests. It has been assumed that they help reduce greenhouse gas (GHG) emissions from the transport sector, but studies show that their fuel efficiency is lower than previously believed, while their black carbon and nitrogen oxides emissions are higher. The consequent reduction in global warming effects from diesel cars may therefore be negligible, perhaps even negative.

Two shared electric car schemes, in Berlin and Paris, have been examined by a recent study. Although both schemes are progressive, Berlin's takes an 'inter-modal' approach to encouraging sustainable mobility, because it integrates electric cars into the wider public transport system. The scheme in Paris, however, focuses on cars as the main form of transport.

The transition to a low-carbon transport system needs a coherent national policy framework that supports all its aspects, according to a review of transport and innovation policy in Finland. Its findings suggest that policy makers need to identify and remove contradictory policies that present barriers to achieving a greener transport system.

Motivation to practise fuel-efficient driving may be more influenced by environmental concerns than by financial benefits, research suggests. In promoting fuel efficiency, this survey of Dutch motorists highlights the power of providing feedback to drivers – both environmental and economic – on their behaviour.
