Thank you! The Paris Agreement only relates to climate change and aims to limit the global temperature increase to 2 degree Celsius in this century. There are other international/regional/bilateral treaties concerning the environment. Alongside customary international law, these treaties make up the international standards in relation to protecting our environment. The integration of these standards to investment treaties is relatively recent and follows the raising awareness on the environmental damage that can be caused by investors' activities at the host State. Stricto sensu, the Paris Agreement creates the obligation on States to prepare "nationally determined contributions". It does not create obligations for investors or the private sector. However, by way of determining their nationally determined contributions, States will surely develop policies that will impact investors. I hope this answer helps!

Thank you! Yes, in the case of the Netherlands, we can talk about four influential domestic cases. Here’s the database of the Sabin Centre on that, which might be helpful: climatecasechart.com/climate-change-litigation/non-us-jurisdiction/netherlands/
