Costa Rica unveils plan to achieve zero emissions by 2050 in climate change fight

Environment minister says under plan, his grandchildren in 2035 will have the same carbon footprint as his grandparents did in the 1940s - and by 2050 none at all

Costa Rica has launched an economy-wide plan to "decarbonize" the country by 2050, as the Central American nation aims to show other nations what is possible to address climate change.

Environment minister, Carlos Manuel Rodriguez, said that if the plan is achieved, his grandchildren in 2035 will have the same carbon footprint as his grandparents did in the 1940s - and by 2050 his grandchildren will have none at all.
