Nauseda informed the summit about "Lithuania's decision to substitute fossil fuels for biomass and eventually to switch completely to biomass in district heating," it said in a press release.

"In Lithuania, the share of biomass in residential district heating has increased from 30 to 70 percent over the last five years, while at the same time average heating prices have fallen by 30 to 40 percent," the president said in his speech.

Nauseda said the global initiative, entitled "Transition to Sustainable Heating", will help meet commitments to cut carbon emissions.

"The initiative is supported by Sweden, Austria, Ukraine, Georgia, and Latvia, with other countries where central heating is indispensable on the way to join it," his office said in the press release.

"In his speech, the president highlighted five priorities that should be immediately included in the world leaders' agenda to preserve priceless natural beauty and diversity for future generations", it said.

These include "climate neutrality and minimized fossil-fuel energy production, promotion of innovation, development of circular economy, increased cooperation between public and private sectors, and unique country-specific tools to fight climate change."
