The phrase "a decrease in carbon" is correct and usable in written English.
It can be used when discussing environmental issues, carbon emissions, or any context where a reduction in carbon levels is relevant.
Example: "The new policy aims to achieve a decrease in carbon emissions over the next decade."
Alternatives: "a reduction in carbon" or "a drop in carbon levels."
"Various processes, including the appearances of living organisms, led to a decrease in carbon dioxide and an increase in oxygen.
It is likely that the development of higher land plants during the Devonian period (from 408 to 360 million years ago) resulted in an increase in atmospheric oxygen and a decrease in carbon dioxide.
In the twelve months since the carbon price was introduced in Australia, our nation has enjoyed nearly unparalleled economic prosperity: low inflation of 2.4percentt, strong growth in the stock market of 23percentt, record low unemployment of 5.8percentt, low interest rates of 2.5percentt (cash rate), strong terms of trade and most importantly a decrease in carbon emissions.
There was also a decrease in carbon deposition with increasing reaction temperature.
Paradoxically, weak environmental regulation significantly facilitates a decrease in carbon intensity through industrial green transformation.
The results indicated that the addition a low amount of Mo to Ni3Al led to a decrease in carbon deposition.
Agricultural practices often lead to a decrease in soil carbon (C), which often begins shortly after a natural system is converted to arable land.
Application of gypsum resulted in an increase in inorganic carbon and a decrease in organic carbon.
Hence, following a ketogenic diet-induced decrement of the respiratory exchange ratio and of metabolic carbon dioxide output, a decrease in arterial carbon dioxide partial pressure or of pulmonary ventilation, or of both, is expected.
A sodium-dependent bicarbonate transporter showed an average 9-fold decrease in transcript level for 3 comparisons, suggesting a decrease in photosynthetic carbon fixation, and subsequently, a lower overall carbon flux may accompany FFA production.
Based on thermodynamics and TEM/EDS analyses, it is supposed that austenite growth is controlled by carbon diffusion in specimens with Si and Mn added, as well as the Fe 0.6 mass% C binary material, while a decrease in the carbon activity gradient with the addition of these elements results in slower reversion kinetics.
