Biden: cut US carbon emissions in half by 2030

President Joe Biden announced at the Leaders Summit on Climate that the US will aim to reduce carbon emissions by 50 to 52 percent by 2030. Climate experts have urged world leaders to cut carbon emissions in order to limit the warming of the planet to 1.5 degrees Celsius. The Paris Agreement sets a 2 C rise within the current century as a maximum, but urges countries to work toward a 1.5 C rise. Recent studies have found that the 1.5 C rise will be reached within five years. (Photo: Ralf Vetterle, Pixabay)
