55  Summary

      Using sub‑method 3, calculating abatement for a population in a measurement period involves estimating the effect of treatment on mean daily emissions of greenhouse gas at sites in the population, using a linear regression model that relates mean daily emissions at sites during the measurement period to a number of independent variables. Variables used in the regression analysis include the mean daily emissions at sites in the relevant pre‑treatment period, and whether the site is in the treatment group in the population. The regression is weighted by the number of days in the measurement period for which there is data, about measured energy consumption at the site, that is used for the purposes of this Part.
      If the estimated treatment effect is statistically significant, abatement for the population is calculated by multiplying the negative of the estimated treatment effect by the number of days for which there is data about measured energy consumption at sites in the treatment group in the population.
