 We need to address renewable energy, we need to look at transportation, we need to look at agriculture. We'll have new materials that better enable us to capture carbon more efficiently. At IBM Research, we're using AI machine learning technologies to help us accelerate the way that we discover and learn about new materials and try and reduce the amount of CO2 that we're actually releasing into the atmosphere. We're looking at sorbent materials, which are usually liquids where you have the flue gas is actually bubbling through it and it's absorbing the CO2 and then we're also looking at membranes which actually can filter it out. There's a huge opportunity to capture the amount of carbon dioxide that's coming out of power plant flue stacks. Carbon dioxide, once it's been captured, has a couple different destinations. We can use it to create plastics or other polymers that have a lot of value.
