CO2 emissions from the combustion of fossil fuels represent largest anthropogenic disruption natural global carbon cycle and lead to an undesirable increase in atmospheric levels. The so-called "carbon-neutral" renewable energy source biomass appears be a promising replacement for fuels. "Combined Energy Biosphere Model" (CEBM), was developed as method calculating content after intensive use biomass. It includes (i) biosphere part computing annual on 2,433 grid elements covering continents’ plant mass soil, well (ii) economic 119 countries. As history understanding (including quantification growth decay by formulae, inclusion deforestation, fuel fertilizer effect) shows, such model (as CEBM) provides needed methodology assess net effects large-scale plant’s atmosphere. Results show that (in systemic view) is “only half neutral” previously thought, even principal level. conclusions indicate (even if valuable mitigation strategy) its potential limited. When interpreting CEBM scenarios, very first priority, reducing current demand most highly preserving climate.

The present need for an energy transition in the wake of a global climate catastrophe led to “EU green deal” which requires system all countries. This study aimis survey aims identify strategies within such based on trend analyses and reports available technologies implementation. Based literature analysis over 300 pieces (of feasibility studies technology implementation with focus Central Europe) statistical levels “energy intensity” (E/GDP) covering three decades countries worldwide, diagnosis is made that steady improvements several dedicated technological areas can be were could still increased future, as required by targets. Across distinct fields economy, concrete options are portrayed: Energy infrastructure, Smart grids, Transmission grid management, Electricity storage, Heat Industrial waste heat; linked diagnosed long-term trends emerging from “Global Change Data Base” GCDB, allowing sectorial so-called intensity, was not yet delivered until now time series literature. main findings show economic sectors clusters most appropriate achieve targets while safeguarding social aspects sustainability.
