The Earth’s average surface temperature is rising as a result of increased greenhouse gasemissions. This means that we face extensive challenges in reducing the anthropogenic climateimpact. With the ambition to map and reduce its climate impact, LBVA (Laholmsbuktens vattenoch avlopp, the administration of sewage treatment in municipalities of Halmstad and Laholm)has undertaken extensive work to compile a climate report for the year of 2016. This shows theoverall climate impact of their operation. The Climate Report covers all sources of emissionsthat occur directly from LBVA's activities, but also the indirect climate impact from purchasedproducts and services. The report apply the CEMAsys accounting tool that categorizes andconverts data into carbon dioxide equivalent (CO2e). Emissions from logistics, energy supplyand the environmental impact of the wastewater treatment process are emissions that LBVAgenerates. This report shows the extent of process emissions in form of methane gas (CH4) andnitrous oxide (N2O) from treatment of wastewater, especially nitrous oxide, which have a veryhigh heating potential and therefore account for a major part of LBVA's climate impact.
