The Paris agreement has accelerated worldwide momentum for strengthening global warming countermeasures.
As most greenhouse gas emissions come from energy consumption, key measures to check global warming are saving energy through efficient use and transitioning to low carbon energy. For example, better fuel efficiency would reduce the amount of carbon dioxide issuing from cars that run on fossil fuels. But to bring about a drastic reduction, it is essential to shift from gasoline to electric vehicles and from fossil fuel power generation to renewable energy and nuclear power that do not emit carbon dioxide. Carbon dioxide emissions can be significantly reduced by electrifying equipment and reducing the carbon content of power sources.
