Climate Change 2022: Mitigation of Climate Change - Full video

Summary

The IPCC's latest report underscores the urgency of immediate and drastic emissions reductions across all sectors to limit global warming to 1.5°C. It highlights the potential for halving emissions by 2030 through technological advancements and behavioral changes. The report emphasizes the pivotal role of energy transition, sustainable agriculture, urban planning, and carbon dioxide removal. It also stresses the need for increased financial investment and international cooperation to achieve climate goals, aligning with sustainable development.

Q & A

What is the current status of global greenhouse gas emissions?

Global greenhouse gas emissions from human activities are at their highest levels in human history.

Has there been any progress in slowing down the growth rate of global emissions?

Yes, there is increasing evidence of climate action, and the average annual rate of growth in global emissions has slowed in the last decade.

What is the critical goal for limiting warming to 1.5 degrees Celsius?

Immediate and deep emissions reductions in all sectors are needed to limit warming to 1.5 degrees Celsius.

What does the IPCC's latest report suggest is possible by 2030?

The report shows that there are options available in every sector that can at least halve emissions by 2030.

What are the signs of progress in reducing emissions?

Half of the world's emissions are now covered by climate laws and policies, and there's a falling cost of renewable energy with significant take-up.

How much of global emissions does the energy sector account for?

The energy sector accounts for about one-third of all emissions.

What major transitions are required in the energy sector to reduce emissions?

Major transitions required include using low emission energy sources like wind and solar, alternative energy carriers like hydrogen and sustainable biofuels, and using far less energy by improving energy efficiency and promoting energy conservation.

What role does agriculture, forestry, and other land use play in greenhouse gas emissions?

Agriculture, forestry, and other land use contribute just over a fifth of greenhouse gas emissions.

What are some ways to reduce emissions in the agriculture, forestry, and land use sector?

Conserving ecosystems, improving food systems, restoring and sustainably managing carbon-rich ecosystems like forests and grasslands, reducing greenhouse gas intensity of food production, and reducing food waste and loss.

How does the IPCC's report address the social aspects of demand and mitigation?

It is the first IPCC assessment to include a chapter on demand services and social aspects of mitigation, highlighting the importance of human behavior in both causing the problem and providing solutions.

What is the significance of urban areas in global greenhouse gas emissions?

Cities and other urban areas, where most of the world's population lives, are responsible for more than two-thirds of global greenhouse gas emissions.

What are the key actions needed in cities to reduce emissions?

Key actions include better city design for collocating jobs and homes, enabling better transportation systems, promoting active transport, electrification, and carbon dioxide removal or storage in urban environments.

What is the potential for emissions reductions in the transport sector?

There is substantial potential for emissions reductions in the transport sector, depending on decarbonizing the power sector and the use of electric vehicles, low emission hydrogen, and biofuels.

What challenges does the industry sector face in achieving net-zero emissions?

Achieving net-zero emissions in the industry sector is challenging and would require new production processes, use of low and zero greenhouse gas electricity, hydrogen, and where necessary, carbon capture and storage.

How crucial is carbon dioxide removal for limiting global temperature rise to 1.5 degrees Celsius?

Limiting global temperature rise to 1.5 degrees Celsius will not be possible without carbon dioxide removal.

What is the current gap between financial requirements and existing financial flows for responding to climate change?

There is a considerable gap, with current financial flows being three to six times lower than the requirements to limit warming to 1.5 or 2 degrees Celsius.

How does the IPCC report link mitigation with sustainable development goals?

The report shows how mitigation goes hand in hand with achieving many of the sustainable development goals, such as green and new infrastructure, which can absorb and store carbon while also delivering health benefits from reduced air pollution.
