Lebanon is among the countries least prepared to face climate change. At the root of this vulnerability is the country¡¯s limited adaptive capacity.

Critical no-regret investments in key service sectors like energy, water, transport and solid waste are urgently needed in the short-term to mitigate the impact of climate change on Lebanon¡¯s development path.
