Obama gave his final address to the United Nations on Tuesday, where he discussed how investing in new technologies can help combat climate change, among other issues.
He highlighted the need for a “new model” for the global marketplace, one that’s both environmentally sustainable and inclusive of rich and poor countries.
The address came just a day before Obama signed a Presidential Memorandum requiring the federal government to consider climate change when setting national security policies.
In the address, Obama said that “investing in research” and providing “market incentives” to develop new technologies is critical to fighting climate change and greenhouse gases.
He also discussed the landmark Paris climate deal, signed in December 2015, giving it another boost in front of world leaders.
