Fig. 3. Comparison of impacts of typical herbicide regimes for conventional, compared with glyphosate-resistant sugarbeet in the UK and Germany in terms of energy requirements (MJ), global warming potential [kg carbon dioxide (CO₂) equivalent], and ozone depletion [kg chlorofluorocarbon (CFC) 11 equivalent] per functional unit. UKA and UKB are two different herbicide regimes used with non-transgenic sugarbeet in the UK, GER is a typical herbicide regime used with non-transgenic sugarbeet in Germany, and Ht is with use of glyphosate only with glyphosate-resistant sugarbeet (Bennett et al., 2004).
