Why was there a reduction in CO2 emissions in 2012?
The largest drop in emissions in 2012 came from coal, which is used almost exclusively for electricity generation (see figure below). Other factors contributing to the lower emissions include decreased demand for transportation fuels and mild winter temperatures that reduced demand for heating.
What was the CO2 level in 2011?
390.9 ppm
The figure shows the global atmospheric concentration of carbon dioxide up to 2010. The value for 2011 is 390.9 ppm but is not included in the chart to ensure consistency with the other greenhouse gas figures.
How much CO2 did the US produce in 2018?
5.27 billion metric tons
Total U.S. energy-related carbon dioxide (CO2) emissions in 2018 rose to 5.27 billion metric tons, 2.7% more than its 2017 level.
What three countries produced the most CO2 per capita in 2012?
2012’s carbon emissions in five graphs
- Carbon emissions rose.
- Renewable energy grew, but fossil fuels still dominated.
- Developing countries produced more emissions.
- The highest emissions came from China, the US, and the EU.
- Per person, Australia emitted the most carbon.
Why did CO2 emissions drop in 2008?
Sky-high fuel prices, declining energy use and a slumping economy gave the U.S. its largest annual decline in fossil fuel-based carbon dioxide (CO2) emissions since 1982, when emissions fell 5.3 percent.
Why did CO2 levels decrease in 2008?
Source: EEA. Of the Kyoto greenhouse gases, CO2 accounted for the largest reduction in emissions in 2008 (Figure 3). This was mainly due to slower economic growth, improved energy efficiency, reduced use of coal and greater use of gas and renewables.
How much have CO2 emissions increased over the last 10 years?
Since 1970, CO2 emissions have increased by about 90%, with emissions from fossil fuel combustion and industrial processes contributing about 78% of the total greenhouse gas emissions increase from 1970 to 2011.
What was the CO2 level in 2010?
390.1
The atmospheric level of carbon dioxide has been steadily rising since the 1960’s. In 2020, atmospheric carbon dioxide levels reached 414.24 parts per million, in comparison to 1960 levels which stood at about 316 parts per million….
| Characteristic | Concentration in parts per million |
|---|---|
| 2010 | 390.1 |
| 2009 | 387.64 |
| 2008 | 385.83 |
What was the CO2 level in 2005?
378.9 parts per million
In 2005 the agency’s index stood at 378.9 parts per million (ppm), a slight increase over 2004 when CO2 levels averaged 376.8 ppm.
