Climate: Enerdata confirms a rebound in CO2's global energy-related emissions in 2017

AFP published on Jan. 29. 2018

Global emissions of carbon dioxide (CO2) related to energy consumption are on the rise again after three years of stagnation, according to preliminary estimates released Monday by the firm Enerdata, confirming recent forecasts of other international experts.

According to Enerdata, CO2 emissions from burning fossil fuels (gas, coal, oil) would have increased by about 2% last year, due to higher coal consumption. After three years of decline, the three countries with the most use of coal have all increased their consumption of this most polluting energy: it jumped 3,7% in China, 4% in India, and recovered slightly in the States. United States (+ 1%).

In China, this rebound is the result of rising electricity consumption and looser regulatory restrictions on coal, in a context of strong economic growth, says Enerdata. In the United States, rising gas prices have helped make coal a little more attractive. To fuel its demand, China has also significantly increased its imports of gas and in particular liquefied natural gas (+ 50%).

The economic recovery in Russia has resulted in a rise in gas consumption after four years of decline, while it fell by 3% in the United States due to a warmer winter, competition from energy sources. renewable and comparatively cheaper coal. China (+ 6%) also pulled global demand for oil last year. It grew by 2% in India with the development of the automobile, barely more than in the United States and Europe.

These estimates confirm those published in November by the Global Carbon Project, the result of the work of scientists from all over the world, and which had chilled the COP23 in Bonn, an international mobilization meeting in the fight against global warming.

For its assessment, Enerdata has identified the data published by the ten countries that consume the most of each energy over the first three quarters and extrapolated the data for the last quarter. The estimate may therefore still vary depending on the cold observed at the end of 2017, which influences gas consumption. But "the increase in emissions is certain," Nathalie Desbrosses of Enerdata told AFP.

Global warming: Australia wants to plant one billion trees by 2050

21 fev 2019 Futura Sciences

Victims of an unprecedented climate crisis, Australia wants to plant one billion trees and hopes to reach its CO2 emissions targets and boost its economy. It follows many other countries that have all announced impressive numbers of plantations. But is it really effective?
.........

https://www.futura-sciences.com/planete ... 050-75093/

And meanwhile Australia exports its coal.
In 2017 Australia exported 372 million tons of coal.

In 2017 thermal coal exports were 200 million tonnes (Mt) worth $ 20.8 billion while metallurgical coal exports were worth 172 billion.

Will these trees survive with the extreme temperatures already encountered :?: .
For this to be really effective, it would also be necessary to convert agriculture to non-tillage and agroforestry.

and it would be necessary above all, to stop this total poisoning of the earth by these chemical poisons destroying bio-diversity much more than this CO2.
It's been a century since the whistle-blowers predicted this catastrophic, apocalyptic state and nobody wanted to hear them, and it's only when the forest burns that we worry about listening to the firefighters. But if it is easy to extinguish the beginning of a fire, when the entire forest has ignited and despite all the efforts made to try to extinguish it, all that remains is ash and desolation. The news only shows what this major work for our civilizations had planned, the Apocalypse (which means revelation), about what would happen to our humanity and the earth suffering. :( : Cry: : Evil:

Raw materials behind half of greenhouse gas emissions, according to a UN report

AFP published the 12 mar 2019

The extraction and production of raw materials, fuel and food contribute to half of global greenhouse gas emissions, according to a UN report, which calls for major reforms of the economy.

Using dozens of data sources, the authors presented Tuesday to decision makers and business leaders gathered in Nairobi for the General Assembly of the United Nations Environment Program (UNEP) a radical alternative: drastically reform the global economy to produce better with less or risk a collapse of the global system.

Despite the commitments to reduce emissions made by the signatories of the Paris climate agreement (COP21), there is little hope of limiting global warming to + 2 ° C, let alone + 1,5 ° C, without an "urgent and widespread transformation", according to experts.

The report estimates that consumption of raw materials such as minerals, water and fossil fuels has tripled since 1990. While the economies of highly populated countries like China and India are growing, the leaders of this report call for a radical overhaul of what fuels this growth.

"No one is saying that countries that are less developed should not have the right to develop," noted one of them, Janez Potocnik. “The question is: is it possible to do it differently, with less consequences than what we see today?”.

The exploitation of resources is obviously driven by a growing demand from a world population that tends to 8 billions of individuals.

The use of fossil fuels thus increased from 6 billion tonnes in 1970 to 15 billion in 2017, despite efforts to transition to greener energies. "The misuse of natural resources has had a significant impact on our quality of life and on the environment", noted Bruno Orbel, former Swiss Minister for the Environment, also co-author of the report.

The text also emphasizes that per capita consumption of raw materials is twice as high in rich countries as in the world average. In developed countries, consumption is 27,1 tons per capita per year against 2 tons in poor countries.

It puts on the table a scenario towards a "sustainable" situation which would involve measures to slow the growth of the use of resources, reducing the pressure on the water and food supply and allowing global growth of 8%.

Conversely, projections for continuing current trends predict a 43% increase in greenhouse gas emissions by 2060. “If you're in power, defend the public interest. general interest is clear today: we must survive, ”insisted Potocnik.

CO2 emissions linked to energy use stabilize in 2019

AFP • 11 / 02 / 2020

After two years of increase, CO2 emissions linked to energy use stabilized worldwide in 2019, thanks in particular to the development of renewable energies in developed economies, the International Agency for energy (IEA).

CO2 emissions worldwide reached 33 gigatonnes in 2019, a level similar to the previous year, despite global economic growth of 2,9%, according to data from the IEA, which previously forecast an increase.

The agency cites as the reasons for this stabilization "the development of renewable energies (mainly wind and solar), the switch from coal to natural gas, and more production from nuclear" in developed economies.

"We must now work hard to ensure that 2019 remains a definitive peak in CO2 emissions and not just another pause in their growth," said Fatih Birol, executive director of the IEA, quoted in a statement. "We have the technologies to do this, we have to use them all," he added.

According to the IEA, emissions from the energy sector in developed economies have fallen to levels not seen since the late 1980s, a time when electricity demand was one-third lower than that today.

Milder weather in several countries and slower economic growth in several emerging markets are also among the factors cited by the IEA.

By country, the United States recorded the largest decline, with a decline of 2,9% or 140 million tonnes of CO2 less.

In the European Union, emissions fell 5% (-160 million tonnes). Natural gas produced more electricity than coal for the first time, underlines in particular the IEA.

Emissions from Japan have fallen by 4% after the recent restart of nuclear reactors.

"This welcome break in the growth of emissions calls for optimism about our ability to fight climate change during this decade," said Mr Birol.

In the rest of the world, however, emissions increased by 400 million tonnes, mainly due to coal-fired power plants in Asia.
