“Renewable energy is a fast-evolving sector and we expect that those regions will have renewable energy sourcing options available in the near future. RE100 recommends that companies should investigate whether onsite renewable electricity for those locations is possible and engage with key stakeholders such as governments and energy companies to develop new options that suit their needs. In addition, a materiality threshold enables RE100 companies to exclude a small number of locations from their commitment when all other options have been exhausted – full details are available in our Matheriality Threshold document.” Source: http://there100.org/faqs
