Klimatpåverkan från svenska befolkningens internationella flygresor. Metodutveckling och resultat för 1990 – 2014
- 2016
-
Reports (other academic/artistic)abstract
- Flygets klimatpåverkan är stor och ökande för rika länder som Sverige. Dagens produktionsbaserade uppföljningssystem bygger på hur mycket flygplanen tankar i respektive land (bunkring) och återspeglar bara utsläppen till första mellanlandning. I denna rapport utvecklas en beräkningsmetod som återspeglar utsläppen från den svenska befolkningens internationella flygresor. Metodiken appliceras sedan för tidsperioden 1990-2014 med hjälp av både resvaneundersökningar och totalstatistik. Beräkningarna visar att antalet internationella resor som svenska invånare gör har ökat med 130 % från 1990 till 2014. Den genomsnittliga flygsträckan för en tur-och-retur-resa har emellertid inte förändrats avsevärt under tidsperioden. Utsläppen per person-km har dock minskat med 37 % mellan 1990 och 2014. År 2014 var utsläppen 190g CO2-ekvivalenter per person-km. En betydande andel av denna effektivisering kan tillskrivas en ökning av kabinfaktorn. De totala utsläppen från svenska invånares internationella flygresor ökade drastiskt 1993-2000, fluktuerade kring samma nivå under perioden 2000-2009, för att sedan åter öka från 2010. När effekterna av utsläpp på hög höjd inkluderas så närmar sig utsläppen 11 Mt CO2-ekvivalenter för 2014 vilket ungefär motsvarar utsläppen från alla personbilstransporter i Sverige. Utvecklingen av utsläpp från flyget kan jämföras med de totala klimatpåverkande utsläppen som Sverige orsakar. Medan utsläppen från svenska invånares internationella flygresor har ökat med 61 % sedan 1990 så har Sveriges officiellt rapporterade totala utsläpp från samtliga sektorer minskat med 24 %. Utan effektiva klimatstyrmedel för flyget riskerar utsläppen från flygandet att bli större än de totala officiella utsläppen redan år 2040.

Measuring greenhouse gas emissions from international air travel of a country's residents methodological development and application for Sweden
- 2018
-
In: Environmental Impact Assessment Review. - : Elsevier BV. - 0195-9255 .- 1873-6432. ; 72, s. 137-144
-
Journal article (peer-reviewed)abstract
- Global civil aviation accounts for 4–5% of total greenhouse gas emissions and these emissions are increasing. In the absence of sufficiently effective global climate instruments, national instruments might be considered as a complement, in which case some way of allocating emissions from international air travel between countries is needed. The purpose of this paper is to develop an accounting method that reflects one country's greenhouse gas emissions from international air travel, and to apply this methodology to Sweden. The new methodology consists of three parts: the number of international air trips made by the country's residents; the average distance of these trips; and the greenhouse gas emissions per passenger km. For Sweden, data for 1990 to 2014 show an increase in the number of trips by Sweden's population of 3.6% per year, resulting in, on average, one international journey (round trip 5800 km) per capita in 2014. The average distance to the final destination has increased only marginally due to simultaneous growth in both long and short trips. However, global average greenhouse gas emissions per passenger km have decreased by 1.9% per year between 1990 and 2014. Because the increase in the number of their trips has outweighed the decrease in emissions per km, the total emissions from Swedish residents' international air travel have increased by 61% between 1990 and 2014. The total emissions from Swedish residents' air travel, including both CO2and non-CO2-effects, were 11 Mt CO2equivalents in 2014, which is the same level as the emissions from Swedish car traffic. This type of reliable data is important when designing policies and for getting public support for new policies.

-
Journal article (pop. science, debate, etc.)abstract
- Sverige och andra länder behöver driva på för att etablera starka internationella styrmedel för att få ner utsläppen från flyget. Detta kommer dock att ta många år. Med tanke på den snabba ökningen av utsläpp krävs därför också temporära styrmedel om Parismålen ska kunna nås.

Estimating car use rebound effects from Swedish microdata
- 2019
-
In: Energy Efficiency. - : Springer Science and Business Media LLC. - 1570-646X .- 1570-6478. ; 12, s. 2215-2225
-
Journal article (peer-reviewed)abstract
- The direct rebound effect for private car transport was estimated by following a large sample of Swedish households (28,876) that acquired a new car in 2009. For some households, this resulted in an improvement in fuel efficiency, whereas others acquired a less or similarly fuel efficient car. The households' travel distances were measured and analysed for a period of 3 years before and 3 years after the car was replaced. This approach differs from previous econometric analyses in which fleet-average changes in distance travelled were studied, often using fluctuations in fuel cost as a proxy for changes in fuel efficiency. No significant bivariate relationship was found between changes in fuel efficiency and annual distance travelled but a multivariate analysis that also included changes in income, number of cars in the household, car weight and car power, resulted in a significant rebound effect of 24 %. Households who bought a car that was labelled 'green' did not exhibit any rebound effect, while households who bought a 'normal' car displayed a rebound effect of 32 %. This could indicate that households that buy a car with improved fuel efficiency for environmental reasons also avoid the economically induced rebound effect. The analysis did not indicate any significant differences in the rebound effect between different socio-demographic groups.

Should environmentalists be concerned about materialism? An analysis of attitudes, behaviours and greenhouse gas emissions
- 2016
-
In: Journal of Environmental Psychology. - : Elsevier BV. - 0272-4944 .- 1522-9610. ; 48:December, s. 1-11
-
Journal article (peer-reviewed)abstract
- This study analyses the relationships between materialistic values, environmental concerns, and greenhouse gas (GHG) emissions in a sample of 1004 Swedish residents. The previously established material values scale (MVS) is employed along with detailed measurements of the respondents' GHG emissions from travel behaviour, residential energy use, diet, and other consumption. The developed structural model reveals a weak but significant association between high MVS scores on the one hand and low environmental concern and high GHG emissions on the other hand. In further analysis, however, the correlation between high MVS scores and high GHG emissions is shown to be traceable to the domain of air travel in the first place, with no correlation found, for example, between MVS scores and size of accommodation and spending on cars, both traditional status commodities. Instead of possessions, the status-oriented materialists in the sample thus appeared to focus more on other aspects of their lifestyle.

The Gothenburg congestion charge scheme: A pre-post analysis of commuting behavior and travel satisfaction
- 2016
-
In: Journal of Transport Geography. - : Elsevier BV. - 0966-6923. ; 52, s. 82-89
-
Journal article (peer-reviewed)abstract
- The article uses the Gothenburg congestion charge scheme, implemented in 2013, as a case study to analyze the effects and perceptions of a policy instrument directly aimed to change the travel behavior of individuals. For the study, a survey was conducted including measures of commuting habits, attitudes (toward the congestion charge, the environment, automobility, and public transport), and satisfaction with travel, along with socio-demographic and geographical variables. The survey was distributed to a panel of 3500 car owners in the Gothenburg region before the implementation of the scheme, with a follow-up one year later. The analysis use group comparisons and a binary logistic regression analysis and results show that the difference in accessibility of different societal functions using private versus public transport affected the propensity to reduce car travel, whereas socio-demographic variables had a low statistical significance, with the exception of women who were twice as likely to reduce their car travel than men. All studied groups reported a more positive view of the scheme at follow-up, although this effect was more pronounced among those adapting their commuting behavior. In none of the studied groups did the implementation of the congestion charge scheme correlate with any significant change in satisfaction with travel.

Local Governance of Greenhouse Gas Emissions from Air Travel
- 2018
-
In: Journal of Environmental Policy and Planning. - 1523-908X .- 1522-7200. ; 20:5, s. 578-594
-
Journal article (peer-reviewed)abstract
- Global greenhouse gas emissions from air travel (GHG-A) are on the rise, and projections point towards a rapid growth in the coming decades. This study aims to examine how local government (cities), addresses GHG-A in their Sustainable Energy Action Plans (SEAP). To fulfil this aim, over 200 SEAPs were analysed focusing on three issues: (1) Treatment of GHG-A in local emissions inventories; (2) Policy initiatives within this domain; and (3) The cities’ perceptions of the conflicts of interests. Results showed that more than half of the cities acknowledge the challenge of GHG-A, around one third include GHG-A in their emissions inventories, and more than one quarter have initiated policy interventions. To categorise these interventions, we have added a mode ‘governing by agenda setting’ to an existing analytical framework, ‘Modes of governing’. With their authority limited to the local setting, this mode of governing is a common channel for cities to push changes at higher levels.
