Table . Contextual parameter characteristics describing cost and emission typologies and country clustering by typology. Contextual parameter magnitude is described as "low" and "high" when statistical differences existed between the low and high typology for a NSS system. "Varies" was used to describe parameters that had no consistent statistical trend between typology groups. A "-" indicates the parameter was not relevant for cost or CI calculations. Relevant systems for each contextual parameter are identified as BR (Biogenic Refinery), NG (NEWgenerator), and RE (Reclaimer) with a filled circle (•) representing the baseline scenario and an open circle (○) representing alternative scenarios. The emission typology was only evaluated for the Biogenic Refinery systems (indicated with an *) because PCA showed no distinct typology clusters for the CRT systems (Figures ). Countries clustered by typology represent the quantity of countries that fall into each cost and emission typology broken down by HDI. Some country quantities are reported as ranges to account for the countries on the border of the typology groups; swapping typologies depended on the NSS system evaluated (e.g., a country could be in the low-cost typology for the baseline NEWgenerator and in the high-cost typology for the alternative NEWgenerator).
