The country, and the world's, first legal investigation about the responsibility of fossil fuel companies on climate change impacts is nearing closure with the submission of the Final Memorandum by petitioners to the Commission on Human Rights.

The investigation has become one of the biggest repositories of evidence on how the fossil fuel industry misled the public on climate change and the human rights impacts and harms it has caused Filipinos. The petition is the first of its kind, but is also part of a recent wave of climate litigation cases emerging worldwide.
