Global gas emissions reached a record high of more than 35 Gt CO2 in 2019. Widespread disruption of human activities and energy consumption caused by the COVID-19 epidemic and lead to an unprecedented 6% reduction in gas emissions by 2020, up to 33.3 Gt CO2. Next, this dramatic decline in air pollution has led analysts to consider long-term changes in the way energy is produced and used worldwide, and – given the ever-increasing rate of renewable energy and growing climate commitment – about 2019. to be a sign of global turbine emissions Clearly, analysts expect a long-term decline in fossil fuels to begin when the annual increase in renewable energy and other non-fossil fuels meet the demand for renewable energy – a period that could be accelerated by both declining energy-related declines (- 4% of global energy demand by 2020 and the increase driven by the rate of growth of renewable energy.
Strong duplication of gas emissions
However, the latest Carbon Monitor estimates (an international partnership launched in 2020 to track global, regional and regional gas emissions are almost real-time), based on comparable data for operations from major countries and sectors8, show a strong duplication of gas emissions. in 2021. Gas emissions between 1 January and 31 December 2021 were only 1% lower than for the same period in 2019. Global gas emissions in 2021 reached 34.9 ± 0.3 Gt CO2 – an increase of 4.8% per annum, which brought just a small amount of gas emissions. 2019 levels. Our estimate is very similar to the latest independent International Energy Agency forecasts for a 4.8% increase in 2021. This gas emissions are an integrated measure of the race between renewable and non-renewable energy sources, and at the global level they argue that the need for renewable and fleeting efforts for ‘better renewal’.
Decline in greenhouse gas emissions
The decline in greenhouse gas emissions in the United States was greater than in any other country (-9.5% by 2020), but recurring (+ 6.5% by 2021; blue bars). The combined reduction of 2020 emissions from smaller countries was also very large (brown bars), but on the contrary there was little recovery in these countries by 2021. Meanwhile, in India, Russia and Brazil, the 2021 release exceeds that of 2019 0.7%, 3.0% and 8.2%, respectively (blue, orange and yellow bars), and China annual release all did not decrease at all, but grew by 0.9% by 2020 and by 5.7% more by 2021 (red bars). These differences are significant indicators of both the magnitude and persistence of epidemic-related disorders in different regions. In particular, the 2021 release is likely to surpass the 2019 release if not in the low-income countries ‘nationwide’ that have not yet recovered from the epidemic.
Similarly, exports of road and air transport have dropped dramatically by 2020. power- and industrial emissions were seen in a significant decline in 2020, with their emissions in 2021 being 1.5% greater and 0.2% lower, respectively, than in 2019 (light green and yellow bars). The increase in energy-related emissions related to 2019 underscores the strong duplication of fossil fuels within the sector that is better able to eliminate carbon.
Further analysis of changes in energy-related production in major countries shows that the sharp decline in the second quarter of 2020 was due to a decrease in carbon dioxide emissions, but the corresponding rise in carbon emissions also caused an increase in carbon emissions in the 2021 energy sector. currently – when demand decreases, the use of fossil fuels decreases, but as demand has doubled, waste producers resume work faster.
Most energy-related stimulants go to mineral oil rather than renewable energy
The latest estimates, therefore, raise doubts in the hope that 2019 will be the world’s largest fossil fuels. Although solar and wind energy continue to grow much faster than fossil fuels. For example, renewable energy became 83% of new energy by 2020 and only China has enormous coal capacity, total energy consumption and gas emissions are growing rapidly in many areas, and some statistics show that most energy-related stimulants go to mineral oil rather than renewable energy. Despite this, the trend over decades of non-fossil fuels and the dramatic fluctuations in carbon dioxide during the epidemic show that the long-term domination of fossil fuels is now dangerous.
When and how soon the use of such fuels will decrease, however, will depend on how successful countries are in estimating the increase in energy demand, preventing further growth of fossil fuels, and accelerating the growth of non-fossil fuels. Although many of the mitigation measures have recently been developed for integrated test models, power system models and industry groups that produce fossil fuels to increase in the coming years, such models have generally and consistently underestimated the falling costs and associated growth of modern renewable energy sources such as solar photovoltaics – and possibly he does too.
If so, as world leaders look to implement the agreements from COP26, and as the latest IPCC reports are released, the most important task may be to remove barriers to the use of renewable resources. In any case, next year should reveal whether 2021 was a fast-moving spike at the beginning of a long-term decline in gas emissions, or whether the extraction of old fuel has more years to do.
