the Researchers, Stefan Wirsenius, and Timothy D Searchinger argues that the increased use of biofuels leads to increased carbon dioxide emissions. So it is, if the large areas of woodland are felled, including Brazil and Indonesia, to prepare the land for cultivation of crops such as wheat, canola, soy and sugar cane for fuel or food production.
But in Sweden there is no deforestation for the production of fuel and/or food crops. In Sweden, instead of about 1 million hectares of arable planted again with the forest since the 1950s. Since the 1930s, the annual forest growth has exceeded harvesting by approximately 20 percent. The standing volume has doubled since the 1920s. In other words, bind our forests more carbon dioxide than a hundred years ago. As long as growth exceeds the wood harvested is our forestry thus carbon neutral and more.
They argue that the increased yield of wood raw material for the Swedish fuel production will encroach on the current yield for the period attributable to the thermal plants and the production of paper, etc., which, in turn, ”need to be compensated by increased logging and the production of materialprodukter anyone else in the world. Probably partly through the exploitation of untouched old-growth forests, inter alia in the tropics”.
This is a mockery of the conditions for a significant domestic and forest-based fuel production. There is space in Sweden's ever-growing stock of wood for a considerable amount of fuel production without competing with the other requirements, or be in conflict with ecological interests.
Only the annual availability of logging residue chips (logging residues) for example, in Värmland, without a from an ecological point of view unacceptable withdrawals, is enough to förgasningsteknik and high energy yield annually produce fuel equivalent to the energy content of 500,000 cubic metres of gasoline, that is to say, about 10 per cent of our current consumption of petrol.
in Conclusion, the two researchers ' conclusions are not for the forests of Sweden.
