Roseville 2040 Chapter9: Resilience and Environmental Protection <br />4. GREENHOUSE GAS EMISSIONS REDUCTION <br />Background <br />Since greenhouse gases (e.g. carbon dioxide) trap heat within the atmosphere, <br />acting to reduce these emissions can help mitigate future climate risks.' <br />Minnesota Statute 216H.02 establishes a goal "to reduce statewide greenhouse <br />gas emissions across all sectors producing those emissions to a level at least 15 <br />percent below 2005 levels by 2015, to a level at least 30 percent below 2005 levels <br />by 2025, and to a level at least 80 percent below 2005 levels by 2050." The latest <br />statewide analysis shows that Minnesota is not currently on track to achieve these <br />targets, with only a 4% reduction from 2005 levels in 2014? With many human <br />activities contributing to the emission of these gases — from driving to work to <br />burning natural gas to heat a home — local governments like the City of Roseville <br />can have a strong influence on the emissions caused by activities within its <br />boundaries. Roseville can lead by example to reduce emissions from City <br />operations through strategies like improving building and fleet efficiency and <br />replacing fossil fuel use with renewable energy. Additionally, the City can use <br />education, incentives, and regulation to impact emissions from residents and <br />businesses. <br />According to the Regional Indicators Initiative, in 2016 Roseville is attributed with <br />an estimated 13.1 tonnes of carbon dioxide equivalents (CO2e) per person for a <br />total of468,159 tonnes.' The greatest source of greenhouse gas (GHG) emissions <br />in the community comes from building energy consumption, making up 56 percent <br />of total emissions (FIGURE 9-1). Broken down by sector, the commercial and <br />industrial sector accounts for 39 percent, while residential energy use accounts for <br />17 percent of all emissions. Broken down another way, electricity emissions <br />account for 33 percent and natural gas emissions account for 23 percent of the <br />community's total. Emissions for vehicle travel make up 42 percent, and <br />treatment of municipal solid waste is 2 percent. Additional sources of emissions <br />not included in this analysis come from air travel and wastewater treatment. <br />' Wuebbles, D.J., D.W. Fahey, K.A. Hibbard, B. DeAngelo, S. Doherty, K. Hayhoe, R. Horton, <br />J.P. Kossin, P.C. Taylor, A.M. Waple, and C.P. Weaver, 2017: Executive summary. In: Climate <br />Science Special Report: Fourth National Climate Assessment, Volume I . U.S. Global Change <br />Research Program, Washington, DC, USA, pp. 12-34, doi: 10.7930/JODJ5CTG. <br />' Minnesota Pollution Control Agency, "Minnesota's GHG emissions: 1990-2014and Next <br />Generation Energy Act goals," 2017, d oi:10.1007/978-1-4419-7991-9. <br />' Metric tons (tonnes) of carbon dioxide equivalent (CO2e) is the typical unit used for <br />greenhouse gas inventories. Along with carbon dioxide, CO2e includes other greenhouse <br />gases (methane and nitrous oxide) that are weighted based on their global warming <br />potential. A metric ton is equal to 1.102 short tons. <br />Chapter9 I Page 7 <br />
