A rapid phase out of coal as an electricity source by 2050 would reduce warming by half a degree, according to the Climate Action Tracker, in an update released today ahead of the Ban ki-Moon climate summit. The Climate Action Tracker, put together by research organisations Climate Analytics, Ecofys, and the Pik Potsdam Institute, has calculated that under current Government policies, the world is on track to warm by 3.7°C by 2100.
The latest update looks at the effect of phasing out fossil fuels in the electricity sector. The CAT team ran a number of scenarios around phasing out fossil fuel emissions from the sector, which produces around 40% of global C02 emissions. The electricity sector needs to be decarbonised faster than other sectors, but instead is heading in the opposite direction, increasing carbon intensity and significantly driven by increased coal use, and making it one of the largest sources of recent carbon emission increases. The CAT scientists calculated that rapidly phasing out coal by 2050 would bring down warming by 0.5°C.
The CAT also found that switching from coal to gas would only achieve 25-45% of what could be obtained by the entire electricity sector switching to renewable energy. Aside from slowing warming, a rapid phase out of coal would also bring multiple environmental and health benefits: in 2010, coal plants produced 24% of the world’s mercury emissions and causes smog and severe health problems, particularly in densely populated areas.
Unabated: the Carbon Capture and Storage 86 billion tonne carbon bomb aimed at derailing a fossil phase out
The climate talks at COP28 have centred around the need for a fossil fuel phase out. Our analysis quantifies the risk posed by restricting a phase out commitment to only ‘unabated’ fossil fuels.
No change to warming as fossil fuel endgame brings focus onto false solutions
The CAT's annual warming estimate has risen by 0.1˚C to 2.5˚C. The estimate is largely influenced by weak existing targets rather than shifts triggered by updated Nationally Determined Contributions.
When will global greenhouse gas emissions peak?
The IPCC says peaking before 2025 is a critical step to keep the 1.5°C limit within reach. With emissions set to rise in 2023, this leaves limited time to act. To assess if we can meet this milestone, we look at when global emissions might peak, as well as what we can do to get there in time.
Wind and solar benchmarks for a 1.5°C world
This report presents a detailed methodology for determining the amount of wind and solar capacity that is required for a country to align with the Paris Agreement’s 1.5°C temperature goal. While the focus of the report is the method, it includes illustrative benchmarks for Brazil, China, India, Indonesia, Germany, South Africa.
A 1.5°C future is possible: getting fossil fuels out of the Philippine power sector
The Philippines is also one of the fastest-growing developing countries: poverty is in decline, access to energy is rising and, with that, demand for energy services. However, fossil fuels still dominate the energy system, accounting for 78% of power generation in 2022. This report sets out what the Philippines government needs to do to get the country’s power sector onto a 1.5˚C compatible emissions pathway, replacing fossil fuels with renewable energy.
Production Gap Report 2023
Governments, in aggregate, still plan to produce more than double the amount of fossil fuels in 2030 than would be consistent with limiting warming to 1.5°C. The persistence of the global production gap puts a well-managed and equitable energy transition at risk.
Emissions impossible: Unpacking CSIRO GISERA Beetaloo Middle Arm fossil gas emissions estimates
This report provides an independent evaluation of the CSIRO and GISERA assessments of the potential greenhouse gas emissions that would result from the exploitation of the Beetaloo fossil shale gas reserves.
Adjusting 1.5°C climate change mitigation pathways in light of adverse new information
This study uses an integrated assessment model to explore how 1.5°C pathways could adjust in light of new adverse information, such as a reduced 1.5°C carbon budget, or slower-than-expected low-carbon technology deployment.
