Life Cycle Initiative (LCI) was jointly established by SETAC and UN Environment in 2002. This initiative is a multi-stakeholder partnership enabling the global use of credible life cycle knowledge by private and public decision makers. The overarching goal of the initiative is to provide science-based life cycle knowledge, advices and capacity building in order to enlighten public and business decisions to help to reach the sustainable development goals (SDGs). This initiative has been playing a key role in providing recommendations on life cycle impact characterisation by organising scientific workshops, where scientists and other stakeholders come together to review best available methods and agree on operational recommendations, and by publishing global guidance documents. In June 2018, the second Pellston Workshop® took place in Valencia bringing 43 people together for one week to work and decide on recommendation updates. This present paper recalls the consensus building process and provides key insights on the outputs from this second international workshop.
