The SAU 70’s GHG emissions for the 2022-2023 school year (listed as 2023 for the purpose of the table below) and projected emissions for the years 2030 and 2050 are shown in Table 2. The forecasted emissions are a “business-as-usual” scenario. Growth projections in emissions are based on anticipated population growth in the towns of Hanover and Norwich. The forecast does not account for the effects of legislation that may reduce emissions from electricity and vehicles in the future. The forecast indicates that if SAU 70 does not take action, GHG emissions will continue to increase.

As shown in Figure 5, the sectors showing the highest GHG emissions are building energy, employee commute, and student commute. Projected emissions to the year 2050 show that these three sectors will continue to be the primary sources of SAU 70’s emissions and therefore addressing these sectors should become a priority.

Figure 6 shows that the majority of emissions in SAU 70 are coming from HHS with 1,473 MTCO₂e released, followed by the Ray School (655 MTCO₂e), RMS, (523 MTCO₂e), and MCS (336 MTCO₂e). Population projections show that in a BAU scenario, the emissions remain relatively constant out to 2050.
