IPCC report: Greenhouse gas emissions must peak within three years to keep world ‘sustainable’

The UN climate experts (IPCC) on Monday published their set of scenarios to limit global warming and its already devastating effects.

LHumanity has less than three years to invert the trajectory of greenhouse gas emissions, the main contributors to climate change, if it is to maintain a “livable” world, UN climate experts warn in a new report Monday.

The Paris Agreement’s most ambitious goal of limiting warming to +1.5°C compared to the pre-industrial era is “out of reach” with current international commitments, IPCC experts point out. And even if “peak emissions” are indeed reached before 2025 and “immediate action” is taken, warming could reach 2°C.

“We are at a turning point. Our decisions today can ensure a future worth living,” emphasizes Giec boss Hoesung Lee.

Reduce use of coal, gas and oil by at least 60% by 2050, UN says

The use of fossil fuels must be sharply reduced by 2050 in order to achieve the major goal of the Paris climate agreement of limiting global warming to +1.5°C compared to the pre-industrial era, UN climate experts (IPCC) warn in their new benchmark on Monday Report.

Without carbon capture (an immature large-scale technology), coal use is projected to be phased out completely and oil and gas use by 60% from 2019 levels by 2050, or to come from zero or low-carbon sources,” estimates the IPCC.

According to the UN, the richest 10% of households are responsible for up to 45% of emissions

Households with the 10% highest incomes in the world alone are responsible for between 36% and 45% of the total greenhouse gas emissions responsible for climate change, UN climate experts (IPCC) point out in a report published on Monday.

Of this top 10%, two-thirds live in developed countries. Emissions related to the lifestyle of the middle and underprivileged classes in developed countries are 5 to 50 times higher than their counterparts in developing countries, the IPCC also points out.

According to the UN, energy efficiency and sobriety could reduce emissions by 70%

Measures on energy demand and the consumption of goods and services would reduce the greenhouse gas emissions responsible for climate change by 40 to 70% by 2050, estimate UN climate experts (IPCC) in their latest report published on Monday.

“Having the public policies, infrastructure and technology to enable changes in our lifestyle and behavior (…) offers significant untapped (mitigation) potential,” said Priyadarshi Shukla, one of the co-chairs of the IPCC Working Group on Solutions to reduce the causes of climate change.
