Time for rigorous actions to cut emissions in half by 2030


The IPCC’s Sixth Assessment Report of Working Group III (AR6 WGIII) on ‘Mitigation of Climate Change’ presented a range of financially sound options for each country to reduce emissions in order to limit warming to 1.5 degrees Celsius.

Pointing out that between 2010-2019, global average annual greenhouse gas emissions were at their highest levels in human history, but growth has slowed, the WGIII report says: “Without an immediate and profound reduction in emissions across all sectors, limiting global warming to 1.5 degrees Celsius is out of the question. However, more and more people are getting it,” he said. evidence that climate action is bringing about change.”

Since 2010, the cost of solar and wind energy as well as batteries has dropped consistently by up to 85%. A growing number of policies and legislation have improved energy efficiency, reduced deforestation rates and accelerated the deployment of renewable energy, scientists say in this latest IPCC report.

“We are at a crossroads. The decisions we make now can ensure a livable future. We have the tools and know-how needed to limit warming.” IPCC Chairman Hoesung Lee said.

The brief for policymakers of the IPCC Working Group III report, “Climate Change 2022: Mitigating Climate Change”, was approved on Monday by 195 member governments of the IPCC, through a virtual approval session beginning on March 21.

“Having the right policies, infrastructure and technology to enable changes in our lifestyles and behaviors could lead to a 40-70% reduction in greenhouse gas emissions by 2050. This offers the potential. significantly untapped,” said IPCC Working Group III Co-Chair Priyadarshi Shukla.

“Evidence also shows that these lifestyle changes can improve our health and well-being.” Shukla said.

Reducing emissions in industry will involve more efficient use of materials, product reuse and recycling, and waste minimization. For basic materials, including steel, building materials and chemicals, low-to-zero greenhouse gas production processes are in the experimental to near commercial stage, IPCC scientists say. commercial.

This sector accounts for about a quarter of global emissions. Achieving net zero will be challenging and will require new production processes, electricity, hydrogen, hydrogen, low carbon capture and storage, and zero emissions at the required levels. Agriculture, forestry and other land use can help reduce emissions on a large scale, while removing and storing carbon dioxide on a large scale.

“There has been a proliferation of laws, policies and technologies to help cut emissions, and they are having an effect. This report provides a great deal of scope for looking at development pathways,” Navroz K Dubash, one of the lead authors coordinating one of the chapters of the report.

The development paths taken by countries at all stages of economic development impact greenhouse gas emissions and thus shape mitigation challenges and opportunities, which vary from country to country. and area.

“For the first time, the report covers how demand for services and the social aspects of mitigation can be used in a way that includes innovation, technology development and transfer, yet puts people into the center” Joyashree Roy, another lead author, said.

The assessment of future pathways in this report covers the short-term (until 2030), medium-term (until 2050) and long-term (until 2100), combining an assessment of commitments and Existing action with an assessment of emissions reductions and their impacts, with respect to long-term temperature outcomes through 2100.

Points out that to accelerate the low-carbon transition in the Global South, developed countries need to ensure greater financial flows and technology transfer in key areas such as renewable energy, electric vehicles , green hydrogen and other sectors, Arunabha Ghosh, Executive Director, Council on Energy, Environment and Water (CEEW), said: “The IPCC report is a stark reminder for all developed countries to dramatically accelerate their transition to a bogus economy.”
