The talk starts with a quiz created by Van der Linden, S. (2022) on What’s the Best Way to Shrink Your Carbon Footprint? New York Times. https://www.nytimes.com/interactive/2022/12/15/opinion/how-reduce-carbon-footprint-climate-change.html
If you're a nerd like me, you may be interested in the meta-study that the quiz is based on: Ivanova, D., Barrett, J., Wiedenhofer, D., Macura, B., Callaghan, M., & Creutzig, F. (2020). Quantifying the potential for climate change mitigation of consumption options. Environmental Research Letters, 15(9), 093001. Available at: https://iopscience.iop.org/article/10.1088/1748-9326/ab8589
