Norway has announced plans to step up its efforts as part of "first aid" to slow climate change.
Norway has led developed nations by investing billions of dollars to slow tropical deforestation.
Prime Minister Jens Stoltenberg, whose country is rich thanks to offshore oil and gas, said new measures to slow global warming were needed now because a new UN-led climate deal is due to be agreed only in 2015 and enter into force from 2020.
"In the meantime we must give the climate first aid," he told a news conference. "The government will step up its efforts to slow deforestation and work to cut emissions that give the greatest climate effect in the shortest time," he said.
Stoltenberg did not, however, announce fresh investments or targets. Deforestation (often clearing land for farms) accounts for about 17% of greenhouse gas emissions from human sources.
Forests, from the Congo to the Amazon, soak up carbon dioxide from the air as they grow and release it when they rot or burn.
Norway has been the most generous nation in giving aid to slow tropical deforestation with annual investments worth $500-million in recent years, funded from its own vast fossil fuel revenues. It has $1-billion programmes in both Brazil and Indonesia and smaller projects in nations including Guyana and Tanzania.
Fossil fuel subsidies
Stoltenberg said that other fast-acting measures that would qualify as first aid included cuts in industrial emissions of soot and methane, a powerful greenhouse gas, and reductions in subsidies for the use of fossil fuels.
Oil Change International, an environmental group campaigning for a shift towards cleaner energies such as solar or wind power, estimates that fossil fuel subsidies worldwide will reach $775-billion in 2012.
It also estimates that Norway itself handed out almost $700-million in fossil fuel subsidies last year.
UN-led talks in Qatar this month ended with a deal to extend the Kyoto Protocol, a weak pact that sets greenhouse gas goals for industrialised nations, until 2020.
That unblocked talks on the new, worldwide deal meant to be sealed in 2015. But world greenhouse gas emissions are rising, led by growth in emerging economies such as China and India. – Sapa
