Air Pollution: Raw Materials Behind Half Of Global Greenhouse Gas Emissions, Says United Nations

“Drastically reform the global economy to get more from less, or risk the collapse of global infrastructure”, UN experts warn lawmakers and businesses around the world saying that extracting and processing materials, fuel and food contributes as much as half of the world’s greenhouse gas emissions

Air Pollution: Raw Materials Behind Half Of Global Greenhouse Gas Emissions, Says United Nations

Nairobi: Extracting and processing materials, fuel and food contributes as much as half of the world’s greenhouse gas emissions, the United Nations (UN) said on Tuesday (March 12), as experts gathered in Kenya to find ways to rein in exploding global consumption. Using dozens of data sources, the authors of a major new report presented lawmakers and businesses with a stark choice: drastically reform the global economy to get more from less or risk the collapse of global infrastructure.

With countries already committed under the Paris climate deal to curb emissions to fend off the worst impacts of global warming, experts said there was little hope of meeting that goal without an “urgent and systemic transformation” in how we use Earth’s resources. The Global Resources Outlook 2019 said that worldwide consumption of basic commodities such as water, minerals, and fossil fuels had tripled since 1970.

With high-population nations such as China and India rapidly expanding their economies, the team behind the report called for a drastic overhaul in how that growth is fed. Janez Potocnik, co-chair of the International Resource Panel said,

Nobody is claiming that the countries which are on the lower level of development should not have the right to develop. The question is, is it possible to do it differently to how we have done it, with fewer consequences than we see today?

The report paints a grim picture of relentless demand for resources as the global population ticks towards eight billion people. The use of climate-warming fossil fuels has increased worldwide from 6 billion tonnes in 1970 to 15 billion tonnes in 2017 despite decades of efforts to steer nations towards greener energy. Water use for agriculture and industry outstripped population growth in the second half of the 20th Century. In 2017, 3,900 km3 of water was withdrawn for commercial purposes — 70 per cent of which went to farming. Bruno Orbele, Swiss former environment minister and one of the report’s co-authors said,

The bad use of natural resources has a big impact on our quality of life and environment.

In line with most economic measurements, the study found that per capita consumption of raw materials in high-income nations was more than double the global average. Richer nations use 27.1 tonnes of raw material per person per year, compared to just two tonnes ahead in low-income countries. The “Towards Sustainability” scenario boosts policy measures to slow the growth of resource use, leading to reduced pressure on food and water supplies and boosting global economic growth by 8 per cent.

Conversely, the “Historical Trends” projection which assumes a business-as-usual approach to resource use would see greenhouse gas emissions shoot up 43 per cent by 2060. The corresponding agricultural pressure to feed a global population expected to tip 10 billion by mid-century would see land given over to agriculture increase by 20 percent, reducing forest cover by 10 per cent and other habitats such as grasslands and Savannah by a fifth. Such a trajectory would shatter any remaining chance mankind has of limiting global temperature rises to 1.5 Celsius, as countries committed to achieving in the landmark 2015 Paris accord. “The way we are currently organised, it isn’t simply enough,” said Potocnik.

In a message to lawmakers and heads of state due in Nairobi for Thursday’s One Planet Summit, Potocnik said the time for vague political commitments on the environment had passed. He said,

If you are in public office, defend the public interest. And it’s clear what is public interest today: we have to survive.

NDTV – Dettol Banega Swachh India campaign lends support to the Government of India’s Swachh Bharat Mission (SBM). Helmed by Campaign Ambassador Amitabh Bachchan, the campaign aims to spread awareness about hygiene and sanitation, the importance of building toilets and making India open defecation free (ODF) by October 2019, a target set by Prime Minister Narendra Modi, when he launched Swachh Bharat Abhiyan in 2014. Over the years, the campaign has widened its scope to cover issues like air pollutionwaste managementplastic banmanual scavenging and menstrual hygiene. The campaign has also focused extensively on marine pollutionclean Ganga Project and rejuvenation of Yamuna, two of India’s major river bodies.
