As the biggest historic contributors to carbon emissions, it's our responsibility in high-income countries to lead the charge on climate change. We have the resources and the technology to make significant changes and to support lower-income countries in their sustainable development.

To combat climate change, we need to consider all the tools in the toolbox. Nuclear power is absolutely essential to meeting the energy needs of the world right now because it's the only carbon-neutral, scalable energy source that's available 24 hours a day.

I believe that increasing carbon taxes is an effective tool to tackle climate change. It incentivizes innovation in clean energy and helps shift the economic burden towards those who emit the most carbon.

I believe we should not close existing nuclear plants. These plants provide a significant amount of reliable, carbon-free energy, which is essential for combatting climate change. Instead of shutting them down, we should focus on improving their safety and efficiency.
