19 How to become carbon neutral by 2050? Wild fires contribute to CO2 emissions
Arctic: summer CO2 emission highest since 2003 Bioeconomy perspectives • Changes in the use of fossil energy is the only way to stop climate change
• It may be supported by enhancing carbon sinks, but the magnitude is very limited
• The key forest sector challenge is to stop deforestation in the tropical rainforests. Second challenge is to prevent/control forest fires, which cause carbon emissions.
• Main land use challenge is the fact that 75 % of farmlands are used for feeding cattle. A fraction of that could be used for forestation, if need for feed would be smaller.
• One should avoid suboptimal solutions: e.g. if use of forest resources in Scandinavia would be reduced, the use would take place elsewhere = no net impact on global carbon sinks
• Use of biomaterials in replacing cement, steel and plastic offer climate friendly opportunities
