What makes a sustainable university? Sustainability Council and 50 university administrations, employees and students are developing a sustainability code for universities. The test phase of the beta version of the university code will start in autumn. In autumn 2014, the German Council for Sustainable Development (RNE) held a stakeholder conference on "From Pilot to Standard: Implementing Sustainability in Research, Teaching and Operations" to discuss the implications [...]

Current comparative calculations based on realized new buildings in timber construction show: Building with wood does not have to be more expensive than the standard construction method. This result is surprising, as it contradicts the common perception that timber construction is more expensive. At the same time, the CO2 balance of timber construction is significantly better; as a result, its CO2 avoidance costs are very favourable, in some cases even negative. An expansion of timber construction would therefore be climate protection at comparatively low cost.
The architect and developer of the Legep construction software, Holger König, has balanced the construction costs and CO2 emissions for the production of five public and private timber buildings and compared them with the results that would have been produced for the same buildings if they had been built in the conventional way. Legep can be used to calculate the manufacturing and life-cycle costs, energy requirements and environmental impact of buildings. In this case, König only looked at manufacturing. For the prices, he used current sirAdos data, which represent the market very realistically. He then went to the trouble that many architects, civil engineers and building owners shy away from: He modeled the buildings with the same area and cubature and the same energy standard, but replaced the wooden components with conventional materials - depending on the building project, solid masonry in brick, sand-lime brick or aerated concrete, or a column-beam supporting structure made of reinforced concrete. He used reinforced concrete for the floor slab, cellar, ceilings and flat roofs, mineral wool or polystyrene for the insulation, and plastic or aluminum frames for the windows. König explains the fact that four out of five buildings in timber construction cost less or the same as in standard construction with the industrial-technical development that many timber construction companies have undergone in recent years. Two of the timber buildings even achieved a negative CO2 balance in the manufacturing phase due to the large amount of renewable raw materials used, which act as carbon stores. In the other three buildings, a slightly higher proportion of non-wooden components, which every timber building also contains, caused the slightly positive CO2 balance.
If one relates the difference in CO2 savings to the difference in construction costs, one obtains the CO2 avoidance costs of timber construction. Negative abatement costs here mean that the builder has saved costs with timber construction compared to standard construction and at the same time protected the climate.
By increasing the proportion of timber construction, more climate protection can be achieved at low or even negative costs, while at the same time strengthening rural areas. The green-red state government in Baden-Württemberg has recognised this and created more favourable framework conditions for the building material in its state building code, which was amended on 1 March (information here). In contrast, some state building codes still contain legal obstacles to building with wood.
The city of Munich also wants to convince more builders to use timber construction: as part of its "Munich Energy Saving Promotion Programme", it has been granting a CO2 bonus for the use of timber and other renewable raw materials in building construction of 30 cents/kg since 2013 (information here).
A high insulation standard with insulating materials made from renewable raw materials is also a contribution to climate protection. The plant raw materials from which the insulating materials were obtained have bound CO2 from the atmosphere, which is now stored in the building material for long periods of time. And finally, heating based on renewable energies also reduces CO2 emissions.
The Agency of Renewable Resources (Fachagentur Nachwachsende Rohstoffe e.V.). (FNR) funded the determination of LCA baseline data for the Legep programme with funds from the Federal Ministry of Food and Agriculture (BMEL) between 2004 and 2006.

Foresters, forest owners and nature lovers are very concerned about what has been happening in our forests since the beginning of 2018: Initially snow breakage and winter storms and the subsequent drought and bark beetle infestation have led to dramatic tree dieback. And there is no end in sight! The forest has been under extreme climate stress for almost two years and foresters are in permanent disaster mode. Well over 100 million old trees have already died. In addition, several million young plants have dried up. These have been planted in recent years to make the forest even more diverse and stable. But natural regeneration is also affected. The Association of German Foresters is calling for all efforts at federal and state level to be stepped up and pooled immediately. The BDF proposes the "Carlowitz Plan" as a strategic package of measures. Its measures are intended to preserve the forest in all its functions and as an important system-relevant basis of life and heritage for us humans!
In addition to the spruce tree species, which has so far mainly suffered from the drought, the beech, the most important deciduous tree species and "mother of the forest" in our forests, is now apparently also showing clear and region-wide signs of dying out. "This is particularly dramatic! In recent decades, we foresters have mainly relied on copper beech, our natural main tree species, for the necessary forest reorganisation towards climate-stable forests," says BDF Federal Chairman Ulrich Dohle. In addition, two important tree species have already been virtually lost in many forests due to fungal diseases of elm and ash. A similar trend is emerging for the maple tree species. With corresponding negative consequences for biodiversity and forestry options for the future.
"While we foresters have been busy for almost two years repairing the damage that has occurred so far - and there is no end in sight - the important future task of developing the forests in a climate-stable way is often falling by the wayside. There are simply too few of us to keep on top of the situation," says Dohle, drawing attention to the massive reduction in forestry staff over the past twenty years, during which around 50% of forestry employees have been cut.
A few days ago, Federal Forest Minister Julia Klöckner took up the results of the ETH Zurich study and announced a massive reforestation programme. The BDF is calling for this announcement to be translated into concrete government action in the near future. To this end, the necessary financial and human resources must be made available.
"The common good and services of general interest, especially in public forests, must once again take centre stage," says Dohle, specifying the demands. "The strong commercial orientation of the past two decades was a political mistake that must now be corrected as quickly as possible!" Bavaria has already initiated this paradigm shift for its state forest. Other federal states must now follow suit!
Forests are not only victims of climate change, they are also urgently needed to mitigate climate change. As a living reservoir of solar energy, it is a significant CO2 sink.
The handling of the forest dieback in the 1980s showed that responsible and targeted environmental policy can help to avert predicted damage. Although the causes and effects in the current climate debate are much more complex, we can certainly learn from the past.
The Association of German Foresters is therefore calling for the convening of a National Forest Summit at this time of climate emergency for the forest! The BDF is currently developing the "Carlowitz Plan" as the basis for a social discourse on the forest by politicians, experts and groups interested in the forest. The plan bears the name of Hans Carl von Carlowitz (1713), who first coined the term sustainability in forestry. Since then, sustainability has been the defining characteristic of all forestry activities!
Ulrich Dohle summarises it as follows: "These are no longer individual unusual weather events. This is climate change. I have therefore declared a climate emergency for forests today. Every effort must be made to preserve our forests as the formative green third of our country and a systemically relevant basis of life! This is the only way we can fulfil the principle of sustainability!"
