Sixty-six countries vow carbon neutrality by 2050: UN

Sixty-six countries have signalled their intent to achieve net zero carbon dioxide emissions by 2050, the United Nations said Monday, seen as a vital goal in preventing catastrophic longer term climate change.

"In terms of the 2050 group, 66 governments are joined by 10 regions, 102 cities, 93 businesses and 12 investors -- all committed to net zero CO2emissions by 2050," the office of UN Secretary General Antonio Guterres said in a statement.
