IPCC Released the third and final part of its 6th Assessment Report

  • Date April 6, 2022

In news:

IPCC released the third and final part of its sixth Assessment Report, aimed at finding ways to mitigate the dangers of rising temperatures.

It highlights immediate and deep emission reductions across all sectors, otherwise limiting global warming to 1.5 Degree C is beyond reach.

Key points:

In 2010-2019 average annual global greenhouse gas emissions were at their highest levels in human history, but the rate of growth has slowed.

Since 2010, there have been sustained decreases of up to 85% in the costs of solar and wind energy, and batteries.

Limiting warming to around 1.5°C (2.7°F) requires global greenhouse gas emissions to peak before 2025 at the latest, and be reduced by 43% by 2030;

Methane would also need to be reduced by about a third.

Investment gaps: The report looks beyond technologies and demonstrates that while financial flows are a factor of three to six times lower than levels needed by 2030 to limit warming to below 2°C (3.6°F), there is sufficient global capital and liquidity to close investment gaps.

 

Suggestion in all sectors to at least halve emissions by 2030

Major transitions in the energy sector. This will involve a substantial reduction in fossil fuel use, widespread electrification, improved energy efficiency, and use of alternative fuels (such as hydrogen).

  • Having the right policies, infrastructure and technology in place to enable changes to our lifestyles and behaviour can result in a 40-70% reduction in greenhouse gas emissions by 2050.

Cities and other urban areas also offer significant opportunities for emissions reductions.  

  • These can be achieved through lower energy consumption (such as by creating compact, walkable cities), electrification of transport in combination with low-emission energy sources, and enhanced carbon uptake and storage using nature.

Reducing emissions in industry will involve using materials more efficiently, reusing and recycling products and minimising waste. For basic materials, including steel, building materials and chemicals, low- to zero-greenhouse gas production processes are at their pilot to near-commercial stage.

  • This sector accounts for about a quarter of global emissions. Achieving net zero will be challenging and will require new production processes, low and zero emissions electricity, hydrogen, and, where necessary, carbon capture and storage.

Agriculture, forestry, and other land use can provide large-scale emissions reductions and also remove and store carbon dioxide at scale.

International cooperation is a critical enabler for achieving ambitious climate change mitigation goals. The UNFCCC, Kyoto Protocol, and Paris Agreement are supporting rising levels of national ambition and encouraging development and implementation of climate policies, although gaps remain.
