Although drained areas for the purposes of forestry and agriculture cover only a few per cent of Sweden’s total surface area, they release enormous amounts of greenhouse gases such as carbon dioxide and nitrous oxide.
‘Greenhouse gas emissions from former peat lands make up about one-fifth of Sweden’s total reported emissions of greenhouse gases. This is roughly the same amount as the country’s entire industrial sector emits through energy consumption,’ says Åsa Kasimir Klemedtsson, researcher at the Department of Earth Sciences, University of Gothenburg.
Sweden’s reporting of greenhouse gas emissions to the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol is seemingly very precise, but by combining the contributions from drained peat lands with the CO2 uptake by forests into a net figure, these emissions are in effect hidden.
‘As the amount of carbon stored in forests is increasing, the emissions from drained peat lands become invisible. And this may explain why measures to reduce these emissions haven’t been discussed to the extent they deserve,’ says Kasimir Klemedtsson.
The second commitment period of the Kyoto Protocol started this year, with new rules for how greenhouse gas emissions from drained peat lands can be reported. This has brought attention to the issue. This autumn, the UN’s climate panel, IPCC, will publish the fifth evaluation report, and also new guidelines for how greenhouse gas emissions due to draining of wetlands should be calculated.
A workshop is currently being planned to shed light on the problem.
‘The purpose of the workshop is to bring attention to and discuss emissions of greenhouse gases from drained wetlands. We want to describe the amounts emitted, how they are reported and which actions could help reduce them. We also want to illuminate what authorities and business actors are doing to limit the emissions, and what else needs to be done,’ says Kasimir Klemedtsson.
The workshop is hosted by the Gothenburg Atmospheric Science Centre (GAC), which is a centre for atmospheric research in the Gothenburg region, and BECC (Biodiversity and Ecosystem Services in a Changing Climate), which is a collaboration between Lund University and the University of Gothenburg.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
