Too little attention is paid to the side effects of emission-limiting measures

24.01.2003


With measures aimed at reducing the emission of pollutants such as ammonia, policy makers pay too little attention to the consequences for the emission of other substances. This is revealed in a computer model constructed by Corjan Brink from Wageningen University during his doctoral research. For example, the model shows that reducing the amount of ammonia emitted leads to an increase in the emission of nitrous oxide (laughing gas).



The computer model developed by the environmental economist Brink, combined with figures from European agriculture demonstrates that the policy aimed at reducing ammonia emission can lead to an increased emission of nitrous oxide or methane. For example, ammonia-limiting measures such as the introduction of low-emission stables and the low-emission application of manure can lead to a tripling in the emission of nitrous oxide.

The results also indicate that a reduction in nitrous oxide or methane results in a reduced emission of ammonia. However, lower nitrous oxide emissions are associated with an increased emission of methane. The outcomes per country differ considerably, dependent on the measures implemented to reduce the emissions.


The most important measures which simultaneously ensure a decrease in ammonia, nitrous oxide and/or methane emissions are less nitrogen in the feed, the more efficient use of artificial fertilisers and manure, and modifications to the feed to increase the productivity of the animals.

In his doctoral research, Brink concentrated on the emission of ammonia (NH3), nitrous oxide (N2O) and methane (CH4) in European agriculture. These substances contribute to various environmental problems such as acid rain and climate changes, and are largely produced by the same sources. Brink discovered that there are almost no quantitative data concerning the side effects of measures to reduce the emission of these substances. He therefore estimated the side effects for a number of relevant measures.

The computer model he developed made it possible to calculate the costs and effects of reduction strategies for different environmental problems in relationship to each other. With this information policy makers can produce cheaper and more effective strategies to reduce the emission of pollutants. The model works for 36 European countries.

The research was funded by the Netherlands Organisation for Scientific Research (NWO).

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
