The world’s forests play a pivotal role in the mitigation of global climate change. By photosynthesis they remove CO2 from the atmosphere and store carbon in their biomass. While old trees are generally acknowledged for a long carbon residence time, there is no consensus on their contribution to carbon accumulation due to a lack of long-term individual tree data. Tree ring analyses, which use anatomical differences in the annual formation of wood for dating growth zones, are a retrospective approach that provides growth patterns of individual trees over their entire lifetime.

Historical changes in soil carbon associated with land-use change (LUC) result mainly from the changes in the quantity of litter inputs to the soil and the turnover of carbon in soils. We use a factor separation technique to assess how the input-driven and turnover-driven controls, as well as their synergies, have contributed to historical changes in soil carbon associated with LUC. We apply this approach to equilibrium simulations of present-day and pre-industrial land use performed using the dynamic global vegetation model JSBACH.

The use of biomass for heat and power production is supported in many IEA countries since biomass as a renewable fuel can effectively substitute fossil fuels and consequently reduce fossil CO2. During biomass combustion, inhalable particulate matter smaller than 10 micrometres (PM10) can be generated which can cause adverse health impacts.

Uses of main primary energy resources, such as coal, oil, and solid biomass, are directly linked with adverse impacts on human health. Air pollution emitted from various activities in the energy supply chains is the main risk factor to human health, along with accidental and occupational risk exposures.

International Renewable Energy Agency chief Adnan Z Amin on where the clean market is headed

The World Bioenergy Association (WBA) has launched its WBA Global Bioenergy Statistics report for 2017. The report claims that across the world, bioenergy remains the biggest source of renewable energy. A number of key findings are unearthed by the report. Most significantly, the global supply of biomass increased to 59.2EJ in 2014, a 2.6% rise on the previous year. In total, it accounted for 10.3% of the global energy supply. Biomass also accounted for three quarters of the total renewable energy supply.

Southeast Asia has considerable resources to produce liquid biofuels sustainably, using biomass feedstocks that would not cause carbon-dioxide emissions or interfere with food supply.

Energy is one of the three focal areas of the EU’s development co-operation with Tanzania. The other two are agriculture and governance.

The West Africa Clean Energy Corridor (WACEC) aimed at accelerating the deployment of utility scale renewable energy into the region, was launched in Cape Town on Wednesday with a warning for gover

This study forms part of a broader project, supported by the German Environment Agency (Umweltbundesamt, UBA), with the primary objective to analyse the current situation and development of the international carbon markets.
