The livestock sector is estimated to contribute 14.5% of all global anthropogenic greenhouse gas (GHG) emissions. This study estimated the costs of reducing emissions from ruminant livestock using five different practices. The findings will help policymakers to understand the cost effectiveness of different interventions in the sector, and the contribution that different policies could make to addressing climate change.

The economic costs of replacing energy inefficient high-pressure mercury (HPM) lamps, used in outdoor lighting, with more efficient alternatives have been explored in a recent study. High-pressure sodium (HPS) lamps would be more cost effective than light-emitting-diode (LED) technology, although the researchers say LEDs could become more economical in the future.

Curefit, which has come under fire from several of its staff that were laid off, is one of the many startups whose business has been directly impacted due to the virus outbreak

TEvery kilometre travelled by car incurs costs to the individual and society that are more than six times those of travelling by bicycle, a new study suggests. The researchers presented a cost-benefit analysis developed for Copenhagen, finding that cars resulted in costs of 0.50 €/km in comparison to 0.08 €/km for bikes.

Hybrid and electric vehicles emit lower levels of carbon dioxide and air pollutants than conventional petrol and diesel vehicles, yet their market uptake in the EU remains limited. New research provides an assessment of the Total Cost of Ownership (TCO) — which combines purchase and operating expenses — of different vehicle types. By comparing historical data on hybrid, petrol and diesel vehicles in three countries (Japan, the UK and the USA), researchers found a strong link between TCO and market share of those vehicles. They also identified a number of ways in which policymakers may promote the adoption of cleaner vehicles through the provision of financial incentives.

Researchers have evaluated how well Swedish policy instruments deal with external environmental costs associated with district heating (DH) plants. They found they have improved environmental performance, but for some plants, the costs of internalising external costs, in terms of taxes, emission permits and environmental fees, are higher than the environmental costs of pollution they produce.

A study has evaluated the Municipal Urbanisation Tax (MUT)—a specific tax for the construction, maintenance, and reinforcement of urban infrastructure—in the city of Tomar, Portugal. The city has a new formula for the tax which is simpler and reinforces efforts to contain urban sprawl. The MUT is a one-time charge applied to new development through land subdivision (Loteamento) or individual buildings, similar to an impact fee. Other municipalities aiming to direct urban regeneration towards their brownfield sites, for example, could learn from the Portuguese experiences.

It can take six to seven years before the financial benefits of brownfield regeneration projects are realised, according to a new study which focused on redevelopment in Michigan, USA. The study examines liability issues, regulatory concerns, clean-up standards and funding mechanisms, and introduces a new model that informs debate on brownfield redevelopment policies and funding mechanisms.

Reluctance to use cost-benefit analysis (CBA) in environmental decision making in Germany stems from a preference for traditional approaches and a fear that it leads to loss of influence. This is suggested by new research based on interviews with those responsible for water policy management.

A new study has investigated the restoration of a damaged estuary in Spain by comparing the costs of installing sewage systems with the associated benefits for water quality and biodiversity in the area. Long-term benefits, particularly in the inner part of the estuary, increased with investment in sewage treatment schemes.

A recent study has assessed the costs and effectiveness of reducing phosphorus pollution for lakes in Scotland, UK, to achieve good ecological status as required by the EU’s Water Framework Directive (WFD). It was found that phosphorus in 72% of the lake area in Scotland could be mitigated at a cost of £5.7 million (€7 million) per year, which is considered a proportionate or reasonable cost given the resulting social benefits.

New research has shown that policy measures in Denmark have successfully reduced total nitrogen loading to 10 estuaries by 39% in recent decades. However, to fully meet the targets of the EU Nitrates Directive and comply with the EU Water Framework Directive in a cost-effective manner, further mitigation measures must be tailored and focused to particular areas.

The socio-economic costs and benefits of adaptation to river flooding caused by climate change have been assessed in a new study. According to the study, adaptation measures could save €53.1 billion every year in flood-related losses across Europe by 2080.

Agricultural run-off can contain pesticides, sediment particles and nitrates and is a major threat to the health of the sea. Although there are policy frameworks to reduce run-off water, they often don’t clearly explain how to maximise benefits. A new study provides an economic framework that prioritises methods based on their cost-effectiveness, which could help policymakers to reduce the pollution of marine ecosystems.

An analysis of conservation management strategies in the EU identifies a number of options for increasing the cost-effectiveness of conservation within the Natura 2000 network of protected areas. More time and money should be given to implementing conservation measures than planning them and governments should guarantee conservation funding over longer terms, say the researchers.

A new model, named OUTOPIE could help design more effective agri-environmental schemes. The model links the farm, field and landscape levels to allow a more accurate assessment of the costs of enrolling specific fields in conservation schemes. Using the model, the researchers were able to assess the cost-effectiveness of different policies for the conservation of the Little Bustard bird (Tetrax tetrax) in France.

A recent project has developed a method to spatially target payments to areas where multiple ecosystem services, combining biodiversity conservation with carbon and water services, are jointly provided, so as to enhance the cost-effectiveness of the PES scheme. The study focuses on Madagascar, but the method could be applied at the national or regional level in any country.

To encourage protection of the environment, payments for environmental services (PES) schemes offer direct incentives to individuals and communities to maintain or improve the provision of environmental services. A recent study suggests indicators to monitor PES must be chosen very carefully to help ensure that monitoring does not cost more than the payments themselves.

Reducing the extinction risk to all threatened bird species by at least one category on the IUCN Red List by 2020 would cost US$0.875 - 1.23 billion (???0.671-0.94) per year, according to a recent study. To achieve this level of support would require an additional US$0.769 ??? 1.08 (???0.59- 0.82) billion per year over and above existing conservation funding for threatened birds.

Costs of defending protected areas from poaching and other illegal activities could be reduced through spatial planning software, finds a new study. Using the tool, the researchers devised new patrol activities in central Africa which would reduce current costs of law enforcement by 35%, as well as providing more effective protection.

Monitoring biodiversity on farms is vital for conservation policies but how much does it cost? In a new pan-European study, researchers develop a standardised monitoring programme and estimate it will cost an average of €8 200 per farm to conduct. This cost could be dramatically cut if volunteer ‘citizen scientists’ or farmers help gather data for the programmes.

Scientists have successfully monitored penguins across the east Antarctic over eight years using a network of remote cameras. The research team present their results in a recent study which describes their method of remote observation as a useful, low-cost tool for monitoring a range of isolated land-breeding marine species.

Monitoring of at-risk sites is important for preventing the arrival and spread of invasive species. However, resources are often insufficient to achieve the level of risk reduction desired by authorities. This study presents a novel framework, based on the ‘acceptable level of risk’ construct, to align needs to reduce risk with available resources.

The cost-effectiveness of agri-environment schemes to conserve species and habitats under the Scottish Rural Development Programme (SRDP) has been assessed by a recent study. Cost-effectiveness was found to vary widely between schemes. Improvements in cost-effectiveness relative to specific conservation objectives might be achieved with increased geographical targeting, advice and monitoring of impacts.

New research compared criteria for accepting environmental risk as tools to evaluate cost-effective measures that would prevent tanker oil spills. The results suggest that the Cost of Averting one Tonne of Spilled oil (CATS) criterion is the best candidate, as it appears to be both practical and meaningful in actual risk assessments, and can lead to sensible recommendations.

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 health impacts of consuming food that has been grown using cadmium-contaminated fertilisers are an increasing concern. New Danish research has estimated that the annual monetary cost of these impacts is €15.53 per km2 of agricultural land treated with mineral fertilisers. This cost rises to €37.04 per km2 if pig manure is used.

The economic benefits of the ecosystem services provided by constructed wetlands far outweigh the costs of maintaining them, new research has confirmed. Analysis of a wetland that treats the third largest lake in Florida, US, shows that it provides ecosystem services worth $1.79 (€1.64) million per year, against costs of less than half that figure.

If the effects of air pollution on climate change are included in air quality strategies, efficiency gains of €2.5 billion can be achieved in the EU, according to recent research.

The policy implications of agricultural losses caused by high concentrations of ground level ozone have been highlighted by a recent study. The study modelled ozone impacts on 14 of the most important crops grown in the Greater Thessaloniki area of Greece. The results provide information about differences in scale of losses and economic impacts across the region which may be useful in designing agricultural subsidy schemes.

A new study has shown that life expectancy and monetary benefits increase significantly when levels of fine particles are reduced further in European cities. It also reveals that living near busy roads could be responsible for a substantial amount of poor health attributable to air pollution.

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 public health impacts of air pollution in Europe remain large, but are falling thanks to regulatory actions to cut emissions, a recent study finds. However, it issues a warning about the public health impacts of emissions from rising levels of international ship traffic.

Ahead of the 2016 Paris Agreement on climate change, various climate and energy policy actions were proposed to target pledged 'nationally determined contributions' (NDCs). Now, researchers have quantified the global impact of implementing these actions on air quality, and determined that they have the potential to substantially reduce air pollution worldwide, with significant co-benefits for human health and agriculture — including the prevention of up to 99 000 premature deaths annually by 2030. These co-benefits could offset the global costs of climate policy; this study thus calls for an integrated policy perspective that aims to maximise the benefits of NDCs for climate and health.

Scientists have discovered a novel way to produce bioplastic, which could be more cost-effective on a commercial scale than current techniques. The new technique, which uses microscopic algae to synthesise a widely used polyester, has the potential to revolutionise plastic production, say the researchers.
