Japanese Prime Minister Kishida Fumio and Brazilian President Luiz Inacio Lula da Silva plan to establish a new bilateral framework in the field of decarbonization.
Kishida is scheduled to visit the South American country from May 2.
Lula will chair this year's meeting of the Group of 20 leaders.
The new bilateral framework will be aimed at utilizing Brazil's rich resources such as biofuels and Japan's expertise in technologies such as hybrid engines.
The plan is expected to see the two countries' public and private sectors increasingly work together.
Brazil is scheduled to host the annual United Nations conference on climate change next year.
The country is also expected to play a key role in the global push to decarbonize.
