Carbon Footprint : A case study on the municipality of Haninge

Abstract: AbstractCarbon Footprints, as an indicator of climate performance, help identify major GHG emission sources and potential areas of improvement. In the context of greatly expanding sub-national climate efforts, research on Carbon Footprint accounting at municipality level is timely and necessary to facilitate the establishment of local climate strategies. This study aims at exploring the methodologies for Carbon Footprint assessment at municipality level, based on the case study of Haninge municipality in Sweden. In the study, a Greenhouse Gas inventory of Haninge is developed and it is discussed how the municipality can reduce its Carbon Footprint. The Carbon Footprint of Haninge is estimated to be more than 338,225 tonnesCO2eq, and 4.5 tonnes CO2eq per capita. These numbers are twice as large as the production-based emissions, which are estimated to be 169,024 tonnes CO2eq in total, and approximately 2.3 tonnes CO2eq per capita. Among them the most important parts are emissions caused by energy use, and indirect emissions caused by local private consumption. It is worth noting that a large proportion of emissions occur outside Haninge as a result of local consumption. Intensive use of biomass for heat production and electricity from renewable sources and nuclear power have significantly reduced the climate impact of Haninge. The major barrier for Carbon Footprint accounting at municipality level is lack of local statistics. In the case of Sweden, several databases providing emission statistics are used in the research, including KRE, RUS, NIR and Environmental Account.
