The United States has the highest concentration of carbon dioxide in the atmosphere, but some plants are far more efficient than others in capturing the carbon dioxide, a new study suggests.
It also found that some plants can be found in more than one state, and the most efficient ones can’t be found anywhere.
The new study, published Monday in the journal Science, used data from a large-scale survey of plants around the country to look at the carbon capture capacity of plants across the country.
The plants were grouped by their carbon content, which ranges from 0.6% to 7.6%.
The scientists found that the United States had some of the highest carbon capture in the world.
The researchers found that, of the 7.7% of plants they measured, 8.1% produced carbon dioxide and 6.8% produced methane.
Those plants produced about 1,800 metric tons of CO2-equivalent per year, which is about 6,500 metric tons.
But, as the researchers noted, these numbers don’t include the carbon that plants can absorb from the atmosphere and use to make carbonate minerals.
The study did not look at whether plants produce carbon dioxide for energy production or carbonate, which would make the number of carbon-capture plants higher.
The United States does not have any carbon-based production facilities for energy, and carbonate is made by using a process called methanation.
It is also used in some food production and as an ingredient in plastics.
The study found that carbonate was a more efficient way to capture carbon dioxide than methane.
The report found that more than half of the plants in the U.S. produce less than 10% of the carbon they capture.
That’s a big problem for people who want to limit emissions and reduce their impact on the environment, because these plants are essential for carbon capture.
A study by a group of scientists in 2014 showed that in the United Kingdom, the United Arab Emirates, Canada and New Zealand, the largest carbon-related emissions are from agricultural and industrial operations.
This is because these countries have relatively low carbon dioxide requirements.
This new study is a good reminder that we need to look more closely at how plants are being used to capture CO2, said Peter H. Hwang, a senior research scientist at the National Center for Atmospheric Research in Boulder, Colorado, and lead author of the new study.
The paper shows we need more work to figure out what the carbon footprint of our electricity generation should be.
