Growing CO2 emissions can change labour productivity in developing countries: Study
Intense heat days resulting from the rising carbon dioxide (CO2) level from the air will influence labour productivity and economic growth, particularly in many developing nations, including India, according to a study.
Outdoor work in tropical areas like Southeast Asia, north-central Africa and northern South America are likely to become more hazardous with the growth in temperatures caused by climate change, according to a new study published in Nature.
For each trillion tonnes of CO2 emissions, gross domestic product (GDP) losses might be nearly half a per cent, showed the study.
The developed nations like Canada, Germany, New Zealand and the United Kingdom have less than 0.1 percent of productivity reduction per unit .
However, productivity declines in developing nations like India, Gabon, Thailand and Malaysia will vary from 3-5 per cent of overall GDP per year for every trillion tonne of carbon emitted, said researchers in the Concordia University.
In 2018, the world totaled roughly 40 billion metric tonnes of CO2 into the atmosphere. This has resulted in economic losses of nearly two per cent of international global GDP, the reseachers said.
However, in lower-income states the economic consequences will be”approximately nine times greater” than countries with higher-income.
Regional increase in the yearly overall heat exposure.
Furthermore, these states are located in areas with intense climate change impacts, including destructive sea level increase, high levels of population increase and delicate food safety.
“The thresholds of heat exposure leading to labor productivity loss are very likely to be exceeded earlier and more broadly in developing countries in warmer parts of the planet,” said Damon Matthews, professor in the varsity.
Loss of growth due to elevated heat exposure will likely be greatest in agriculture, mining and quarrying, manufacturing and construction – sectors which accounts for 73 percent of output in low-income nations’, the investigators noted.
“These states are also more vulnerable as a greater fraction of their workforce is employed in such sectors and since they have less ability to execute infrastructural changes that deal with a changing climate,” Matthews added.
For the study, the team used calculations on popular guidelines regarding remaining time recommendations per hour of labor and heat exposure. The calculations were based on historical and future increases of heat exposure with simulations from eight different Earth Systems Models.
The estimate of productivity loss was based on wellness guidelines regarding labor in extreme heat.
The consequences predicted in the analysis indicate the direct effect of CO2 emissions. “The impact scales fairly well with the complete amount of emissions we produce,” Matthews explained.
The findings can help nations adopt measures to mitigate emissions, as”every additional tonne of CO2 emission which we create will have this extra impact, and we can measure that growth,” Matthews explained.
