Governments can start a global cascade of "positive tipping points" to cut prices and carbon emissions by using mandates to switch investment from polluting fossil fuels to clean technologies, according to a new report launched today at Climate Week NYC.

Researchers found that regulatory mandates with specific timeframes will ensure clean technologies become cheaper than fossil fuel alternatives up to three years earlier worldwide—reducing carbon emissions in the power, transport and heating sectors by at least 75% in 2050.

The report compares the effectiveness of regulatory mandates, subsidies and carbon taxes in more than 70 countries to see which would most quickly lead to positive tipping points in terms of cheaper prices for consumers, enabling clean technologies to outcompete fossil fuels in major emitting sectors.

The researchers examined four sectors: power, heating, light road transport and heavy road transport.
