The carbon footprint of the Rugby Championship will be reduced next season.

The New Zealand Herald reports that from 2021, the All Blacks will only travel to one of Argentina or South Africa each year, but will instead play two tests there rather than one.

The country they don't travel to in a given year will come down to New Zealand for two tests.

The same change will apply to the Wallabies, who will visit the country the All Blacks don't travel to and welcome the team Ian Foster's men don't host.

For example, in 2021 the All Blacks could host two tests against the Springboks before travelling for two tests away in Argentina, before the reverse occurs in 2022.

The All Blacks and Australia will continue to play home and away tests each year as will Argentina and South Africa.

Former All Blacks Coach Sir Graham Henry joins Mike Hosking to share his thoiughts on the changes.
