The report provides an exhaustive list of solutions across the energy, buildings, transport, land and industrial sectors which show that it is possible to cut emissions quickly and cheaply

The United Nations’ climate science body, the Intergovernmental Panel on Climate Change (IPCC) published the third instalment of its Sixth Assessment Report (AR6) April 4, 2022. The report prepared by the IPCC Working Group III (WG-III) focuses on the mitigation of climate change, ie, the solutions necessary to halt global warming.

The full report collates the latest scientific research from across the world and extends to thousands of pages. But a condensed 63-page summary, titled the Summary for Policymakers (SPM) captures the key highlights.

Here are six takeaways from the SPM:

1. Greenhouse gas (GHG) emissions were 54 per cent higher in 2019 than they were in 1990, but growth is slowing

In 2019, global net anthropogenic GHG emissions were at 59 gigatonnes of carbon dioxide equivalent (GtCO2e), 54 per cent higher than in 1990. Net emissions refer to emissions accounted for after deducting emissions soaked up by the world’s forests and oceans.

Anthropogenic emissions refer to emissions that originate from human-driven activities like the burning of coal for energy or cutting of forests. This emissions growth has been driven mainly by CO2 emissions from the burning of fossil fuels and the industrial sector, as well as methane emissions.

But the average annual rate of growth slowed to 1.3 per cent per year in the period 2010-19, compared to 2.1 per cent per year in the period 2000-09. At least 18 countries have reduced GHG emissions for longer than 10 years on a continuous basis due to decarbonisation of their energy system, energy efficiency measures and reduced energy demand.
