The goal of net-zero carbon by 2050 is almost certain to be drastically curtailed by its costs and lack of feasibility.
The International Renewable Energy Agency, an intergovernmental body, estimates that the world needs to invest $115 trillion in clean technologies such as solar and wind power and electric vehicles to limit global warming since 1900 to 1.5 degrees Celsius, the goal of the 2015 Paris climate agreement that was signed by 195 countries.
Much of the reduction would have to come in India and China, which would need to invest $21 trillion to overhaul transportation and construction while building nuclear, wind and solar facilities to reach zero net carbon emissions by 2060, according to the Wall Street Journal. But 57% of China’s energy consumption in 2020 was supplied by coal, and its consumption of that commodity is forecast to rise 6% from 2020 to 2025.
