The evidence provided shows that the company has set specific targets for sourcing 100% ProTerra certified soy lecithin by 2018, 100% RSPO certified palm oil/palm kernel oil by 2015, and 100% cocoa and hazelnuts by 2025 and 2020 respectively. However, these targets do not explicitly mention "zero conversion," which typically refers to a commitment to not convert any more natural habitats into agricultural land. Thus, it's not clear from the provided information whether these sourcing targets are linked to a zero conversion commitment. The evidence provided does not detail how the company plans to achieve these targets, what actions it plans to take, what resources it plans to allocate, or what KPIs it will use to measure progress.
