World leaders have agreed to a consensus on the war in Ukraine, climate change and energy security at the G20 summit in New Delhi.
In a leaders' declaration issued on day one of the summit on Saturday, the Group of 20 (G20) nations agreed on the Ukraine conflict that all states "must refrain from threats" and that "today's era must not be of war".
Going into the summit, there had been concern a declaration might not be reached due to Russia being unwilling to condemn its military action.
However, the joint statement also made the concession that "there were different views and assessments of the situation".
The declaration said G20 members reiterated their national positions, along with warning the use of nuclear weapons in the situation was "inadmissible".
The leaders' declaration also called on Russia and Ukraine to ensure grain and goods deliveries were unimpeded and emphasised the need to accelerate efforts to phase down the use of coal.
Earlier at the summit, Prime Minister Anthony Albanese used a speech to urge nations to commit to net-zero to lessen the impact of devastating natural disasters.
Mr Albanese said urgent action was needed to prevent a further exacerbation of climate change.
“Our communities have endured another year of extreme climate impacts,” he told world leaders at the summit.
"Devastating weather events have affected so many nations, including Australia.
“The science is clear: our climate has already changed.
"We are united in our ambition for a net-zero future.
"Now we must turn our hands to action: urgent, comprehensive action.”
During his intervention at the summit, Mr Albanese touted the federal government's net-zero transformation and $40 billion for energy transformation projects.
He urged the G20 economies to increase production of renewable energy technology.
Mr Albanese said Australia was committed to stepping up on climate action.
"Australia has long been a reliable global energy supplier, and we continue to be, but as the world decarbonises, what we export will change," he said.
"We are expanding our capacity to provide the minerals, metals and clean energy components to help decarbonise our region."
During his speech, Mr Albanese also hit out at Russia's invasion, which has been ongoing since early 2022.
"(Prime Minister Modi) has steered the G20 through another challenging year, a year made all the more challenging, of course, by Russia's illegal and immoral invasion of Ukraine, which I condemn in the strongest terms," he said.
Russian President Vladimir Putin decided to skip this year's summit, with Russian Foreign Minister Sergey Lavrov attending in his place.
The prime minister later held bilateral talks with Japanese Prime Minister Fumio Kishida.
The pair discussed climate change and energy security, along with relations in the Pacific.
Mr Albanese congratulated the Japanese prime minister on the recent release of treated radioactive water from the Fukushima nuclear power plant, following the tsunami and nuclear disaster in 2011.
He also held meetings as part of MIKTA, an association of leaders from Mexico, Indonesia, South Korea, Turkey and Australia.
The prime minister held informal talks on Friday night with European Commission President Ursula von der Leyen on a free-trade agreement between Australia and the EU, which had previously been stalled in negotiations.
The pair spoke about finalising the agreement as soon as possible.
New Delhi has come to a standstill due to the summit, with police closing off large sections of the city.
Nearby businesses and schools have been instructed to close as part of security measures
During the opening remarks, Mr Modi said the G20 had agreed to add the African Union, made up of 55 countries from the continent, as a permanent member of the bloc.
