Tunings and updates to BAU in recent versions of the FeliX model:
- FeliX Model (a/o 21 December 2015)
- Raise Spared Ag Land and Forest Land Yield to 15 biomass ton/yr/ha, in accordance with Berndes et al. 
- Introduce Emissions per ha Grassland Conversion (17 GtC/ha, or 20% of forest carbon stock). This is multiplied by Agriculture Other Land Allocation Rate, to calculate a contribution to C Emissions from Land Use Conversion.
- Eliminate FAO Fertilizer Emissions (Fertilizer Emissions Factor == 0). These are already included in non-CO2 forcings (nominally RCP 4.5), and associated uncertainty is covered by RCPs 2.6 - 8.5. These emissions previously constituted 14% of LULUC sector emissions in 2011.
- Decrease Climate Sensitivity to 2xCO2 to 2.5 W/m*m (from 3.0). This brings Temperature Change from Preindustrial into better agreement with HadCRUT4 and GISS anomalies, and is in line with the IPCC WG4 central value (2.5 W/m/m) as well as the WG5 range (1.5-4.5 W/m/m).
- Increase Flux Atmosphere to Ocean to match IPCC WG5 data by decreasing Ref Buffer Factor by 20%.
- Increase Energy Demand 1900 Calibration from 120 Mtoe/yr to 500 Mtoe/yr to match emissions data for the early industrial period. Despite the large increase, this is a very minor effect.
- Reduce Coal Price toe and Oil Price toe during periods [1900-1940] and [1920-1980], respectively, to better match historical data.
- Increase C Emission from Oil Energy by 2.5 GtC (cumulative) between 1900 and 1950 to match emissions data for the early industrial period.
- Increase C Emission from Coal Energy by 12.5 GtC (cumulative) between 1900 and 1950 to match emissions data for the early industrial period.
- Updated energy sector to latest EIA data (PE, coal, oil, and gas production)
- Recalibration of nominal Energy Demand per Capita - included annual geometric increase of 0.1% in per capita energy demand over period [1900-2100] (above at right).
- This change affects Total C Emission from Energy Sector, Net Emissions, Atmospheric Concentration CO2, etc.
- The effect will be correlated across most scenarios, so impact estimates should not change by any significant amount.
- The former baseline can be recovered by setting Energy Correction Annual to 0.000 in the Energy_Market Share sector of the model.
- Include agricultural residue collection and processing from 10% of arable land (5.5 Gt/ha/y) for bioenergy production (up to 14EJ/y in 2100). Collection area is scaled linearly over 20 years beginning in 2015. Previously, there was no collection of residues in BAU.
- Include carbon penalty for conversion of natural to managed forest. Penalty is equal to 50% of areal forest carbon stock (nominally 85 tC/ha), spread out over ten years after land use change.
- Changed Potential Land Based Biomass Production to Actual Land Based Biomass Production when calculating carbon credit for bioenergy production (Carbon Storage in Biomass for Energy). This corrects a bug which overestimated carbon credits (by about 1 PgC in BAU and 0.2 PgC in all BioEnergy-class scenarios) when Potential Biomass Energy Production from Resources outstrips Potential Biomass Energy Production from Infrastructure or Total Biomass Demand.
- Changed Life Expectancy Normal from 28.6 years to 29.2 years to match WB data & WPP MedVar projection.
