This document discusses how Open Strategic Autonomy (OSA) and the green transition are related. On the one hand, OSA refers to the balance between the capacity of acting autonomously and openness in strategically important policy areas, which enhances the resilience of countries. On the other hand, the green transition means a departure from fossil fuels and overconsumption to a low-carbon paradigm and a sustainable model of growth, addressing environmental challenges such as climate change and resource overexploitation. The green transition has the potential to mitigate strategic dependencies across various sectors, including energy, food and agriculture, but it can also pose novel challenges by requiring the acquisition of critical raw materials, exposing countries to new geopolitical risks and supply interruptions. New technologies and innovation play a crucial role in achieving OSA, with a focus on finding sustainable alternatives and the competitiveness of the industries. This goal also requires a collaborative and strategic approach, with a special attention to less developed countries and regions, in order to ensure that no one is left behind. Finaly, the document highlights the challenging balance and potential synergy between OSA and the green transition in the path towards a sustainable future.
