DN Debatt: LRF och Svenskt flyg svarar inte om klimatmålen

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Sammantaget ser vi inget i motdebattörernas argument som talar emot att införa styrmedel, till exempel konsumtionsskatter, inom dessa områden där inga stora tekniska lösningar finns i sikte, skriver 14 miljö- och energiforskare i slutrepliken till sin text om flyg- och köttskatt (26/2).

Nu krävs kraftfulla åtgärder mot nötkött och flygresor

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Svenskarnas globala utsläpp från köttkonsumtion och flygresor motsvarar hälften av de totala utsläppen på hemmaplan. I vår rapport till Naturvårdsverket föreslår vi tydliga styrmedel – som nya skatter – för att begränsa konsumtionen på dessa områden, skriver 14 miljö- och energiforskare.

- Changes in human diets hold significant greenhouse gas emissions mitigation potential. In this paper, we use a field experiment to analyze the effects of implementing a label with greenhouse gas emission information for each dish at a restaurant. The traffic-light colored label was implemented in a student catering facility with 300–600 servings every day, and covered all seven dishes on offer. Individual level sales data including an anonymous identification number, gender, and age was collected both during the label phase and during a five-week control phase prior to the introduction of the label. We found that sales of green labeled (low emission) meat dishes increased by 11.5% compared to the control phase, whereas sales of red labeled meat dishes were reduced by 4.8%. Although the label had an effect on consumer behavior, emissions decreased modestly by 3.6%. We did not find evidence for different reactions to the label based on gender or age. © 2017 Elsevier B.V.

How can the EU climate targets be met? : A combined analysis of technological and demand-side changes in food and agriculture
- 2016

Tidskriftsartikel (refereegranskat)abstract
- To meet the 2 °C climate target, deep cuts in greenhouse gas (GHG) emissions will be required for carbon dioxide from fossil fuels but, most likely, also for methane and nitrous oxide from agriculture and other sources. However, relatively little is known about the GHG mitigation potential in agriculture, in particular with respect to the combined effects of technological advancements and dietary changes. Here, we estimate the extent to which changes in technology and demand can reduce Swedish food-related GHG emissions necessary for meeting EU climate targets. This analysis is based on a detailed representation of the food and agriculture system, using 30 different food items. We find that food-related methane and nitrous oxide emissions can be reduced enough to meet the EU 2050 climate targets. Technologically, agriculture can improve in productivity and through implementation of specific mitigation measures. Under optimistic assumptions, these developments could cut current food-related methane and nitrous oxide emissions by nearly 50%. However, also dietary changes will almost certainly be necessary. Large reductions, by 50% or more, in ruminant meat (beef and mutton) consumption are, most likely, unavoidable if the EU targets are to be met. In contrast, continued high per-capita consumption of pork and poultry meat or dairy products might be accommodated within the climate targets. High dairy consumption, however, is only compatible with the targets if there are substantial advances in technology. Reducing food waste plays a minor role for meeting the climate targets, lowering emissions only by an additional 1–3%. © 2016 The Authors

How Do Dietary Choices Influence the Energy-System Cost of Stabilizing the Climate?
- 2017

Tidskriftsartikel (refereegranskat)abstract
- We investigate how different global dietary scenarios affect the constraints on, and costs of, transforming the energy system to reach a global temperature stabilization limit of 2 degrees C above the pre-industrial level. A global food and agriculture model, World Food Supply Model (WOFSUM), is used to create three dietary scenarios and to calculate the CH4 and N2O emissions resulting from their respective food-supply chains. The diets are: (i) a reference diet based on current trends; (ii) a diet with high (reference-level) meat consumption, but without ruminant products (i.e., no beef, lamb, or dairy, only pork and poultry); and (iii) a vegan diet. The estimated CH4 and N2O emissions from food production are fed into a coupled energy and climate-system optimization model to quantify the energy system implications of the different dietary scenarios, given a 2 degrees C target. The results indicate that a phase-out of ruminant products substantially increases the emission space for CO2 by about 250 GtC which reduces the necessary pace of the energy system transition and cuts the net present value energy-system mitigation costs by 25%, for staying below 2 degrees C. Importantly, the additional cost savings with a vegan diet--beyond those achieved with a phase-out of ruminant products--are marginal (only one additional percentage point). This means that a general reduction of meat consumption is a far less effective strategy for meeting the 2 degrees C target than a reduction of beef and dairy consumption.
