Grounded by the prices : Internal carbon pricing as a means to reduce corporate air travel
Many large companies use mechanism called internal carbon pricing (ICP) as a means to voluntarily reduce their emissions, when there is no external carbon pricing by the regulator, or such price is deemed insufficient to deliver the level of emission reductions a company wants to achieve. With ICP …

Characterizing the Drivers of Carbon Use in Post-Anoxic Denitrification
… result from post-anoxic denitrification using internal carbon that was stored in the anaerobic zone. An investigation into the factors affecting internal carbon-driven (internal C) denitrification was done via a series of batch tests. The capacity for internal C denitrification was demonstrated …

Determining transpiration efficiency of eight grain sorghum lines [Sorghum bicolor (L.) Moench]
… both field and the field-pot studies (p<0.05). Internal carbon dioxide (Ci), an indicator of intrinsic transpiration efficiency, differed among lines under field conditions (p<0.05). Leaf relative water content (RWC), measured in the greenhouse, and did not differ among the eight accessions. No …

Optimizing Enhanced Biological Phosphorus Removal at WRRFs: Impact of Low DO Operation and Full-Scale Strategies
… High rates of denitrification fueled by internally stored carbon in the post-anoxic zone were found to co-occur with elevated PAO activity, and subsequent batch tests indicated post-anoxic phosphorus uptake rates ranging from 3 to 40 percent of the aerobic phosphorus uptake rates. …

Palaeoclimatology of the late Palaeocene to middle Eocene: geochemical records of stable and transient climate states
… to two periods of warming where significant carbon isotope perturbations may indicate the forcing of the Earth's climate into an alternative quasi-stable state. The Palaeocene { Eocene Thermal Maximum (PETM) represents a significant input of exogenic carbon into the atmosphere over the course …

Ship-pack replenishment optimization in a two-echelon distribution system with lost sales and seasonal product obsolescence
… The cost input change is formulated as an internal carbon tax that would significantly impact transportation costs. The sensitivity analysis concludes that the optimal replenishment policy consistently yields 0.7 - 1.8% savings as costs are varied.

Urban-Scale Decomposition of Carbon Peaking Targets in the Yangtze River Delta from a Consumption-Based Responsibility Perspective
Under the background of the carbon peaking and carbon neutrality goals, the scientifically grounded decomposition of the carbon peaking target to the city level has emerged as a vital issue in China’s climate governance. As one of the regions with the highest economic development and strongest …

Using cathodic protection to control corrosion of reinforced concrete structures
… a high frequency of 10,000 Hz and an internal carbon fibre electrode method are recommended. Regarding the CP for the chloride contaminated reinforced concrete exposed to the atmosphere, it is suggested that adopting an instant-off potential of -500 mV with respect to Ag/AgCl/0.5KCl …

Carbon gains, losses, and feedbacks in shallow, eutrophic lakes of phytoplankton and macrophyte dominance
… as an important component of the global carbon cycle, yet anthropogenic activities that alter their community structure may change the way they transport and process carbon. This research focuses on the relationship between carbon cycling and community structure of primary producers in …

Impacts of heat waves on food quantity and quality of soy bean/corn in the Midwest at ambient and elevated [CO2]
… would reduce stomatal conductance (gs) and the internal carbon dioxide concentration inside the leaf (Ci) and increase photorespiration. In the long term heat waves would decrease the operating efficiency of photosystem II or alter leaf biochemical properties, i.e. the maximum rate of rubisco …
