Some countries (including Saudi Arabia) have questioned the scientific basis for the need to limit temperature increases to 1.5°C. ECO would like to remind everyone, but especially these countries, that Article 3.3 of the Convention (remember it?) states that ‘Parties should take precautionary measures to anticipate, prevent or minimise the causes of climate change and mitigate its adverse effects. Where there are threats of serious or irreversible damage, lack of full scientific certainty should not be used as a reason for postponing such measures’. ECO calls upon Parties to enhance their implementation of the Convention to fulfil this agreed mandate.
