The Samoa government is considering using wood to generate electricity.
It says wood can be a cheaper source of fuel than oil.
The government is targetting the use of invasive tree species like tamarin and African rubber.
The opposition environment spokesperson, Toeolesulusulu Cedric Schuster, backs the idea, saying it's technology that's been around a long time.
He says tamarin is a very invasive species that needs to be removed.
However Toeolesulusulu says the government's proposal is short on detail.
He wants to know how it fits with the big investment the government has already made in solar and diesel.
And he wants to know what measures are suggested to cut carbon emissions, and the harvesting and replanting rates.
