To achieve the international goal of limiting global warming to 1.5 degrees Celsius, requires carbon dioxide (CO2) emissions to be reduced by 45%. 39; here 2030 compared to the level presented in 2010.This is stated in the special report on the global warming of the Intergovernmental Panel on Climate Change (IPCC).
At a press conference, the researcher at UNAM Science Center Atmosphere Graciela Raga, reported that the special report examined the difference between impacts of 2 ° to 2100 or from 1.5 to 2100.
"To limit the heating to 1.5 degrees Celsius up to 2100, the emissions of CO2 would be zero between 2045 and 2055 ", said the Specialist of the National Autonomous University of Mexico (UNAM) Graciela Raga.

The Doctor of Atmospheric Sciences explained that to limit warming to 2 degrees Celsius by the end of the century, emissions must be reduced by 20% by 2030 and reach zero. in 2075.
"In most scenarios, carbon capture options must be used in the atmosphere to limit warming to 1.5 degrees Celsius," he said.
It is therefore necessary that countries work for the development of new energy production systems . In addition, changes in the infrastructure of urban planning, land use, energy efficiency in buildings and significant reduction of emissions in transport.
The researcher points out that, according to the report, such transitions are unprecedented.
"Drastic reductions in electricity production, with a revolving production of between 70 and 85 per cent to 2050 and the removal of mineral carbon," he said.
To achieve the goal of reducing emissions in industries it is possible to use existing technologies, badociated with best practices such as electrification, hydrogen, process efficiency, breeding sustainable, product substitution.
