In this work we present two unit-level decommissioning schedules that are aligned with a Paris Agreement compatible CO2 emission reduction pathway. Both of these schedules require 4.2 GW of coal capacity to be retired each year, and units currently under construction would only be able to operate for four years at the most.

Key findings

To contribute to the achievement of the Paris Agreement, South Korea needs to phase out coal from its electricity sector before 2030. The country’s 9th Basic Plan for Electricity Power Supply and Demand (9th BPESD) presents a unit-level operation schedule for coal power plants that would see nearly 27 GW of coal-fired power capacity still online in 2034, with coal eventually being phased out in 2054, almost 15 years later than is required to be Paris Agreement compatible.

In this work we present two unit-level decommissioning schedules that are aligned with a Paris Agreement compatible CO2 emission reduction pathway. Both of these schedules require 4.2 GW of coal capacity to be retired each year, and units currently under construction would only be able to operate for four years at the most.

Coal-fired power plants are a significant source of air pollution in South Korea, which has been linked to premature deaths due to increased risk for cardiovascular diseases, chronic and acute respiratory diseases, and other health impacts such as pre-term births and depression.

Avoided health impacts under accelerated coal phase out

Following the two Paris-compatible decommissioning schedules presented in this study could halve the number of premature deaths linked to air pollution from South Korean coal plants within the next 5 years and save over 18,000 lives (over 12,000 lives within South Korea) until the end of their operation, when compared to the current policy plan of phasing out coal in 2054.
A corresponding reduction of over 1,700 preterm births (800 within South Korean boundaries), 3,000 new asthma cases (2,500 within South Korean boundaries) and more than 4.6 million work absence days (2.8 million within South Korean boundaries) is estimated to result from the accelerated decommissioning schedule as compared to current policy plans (see Table above).

Tripling renewables by 2030: interpreting the global goal at the regional level

At COP28, governments agreed to triple global renewable capacity by 2030. This report breaks down what a 1.5ºC-aligned renewables rollout would look like at the regional level and calculate the associated investment needs.

Submission to the Australian Treasury consultation on the Petroleum Resource Rent Tax

As the gas industry in Australia has grown exponentially, the profit taxes it pays to the government have proportionally plummeted, presenting an opportunity to change this regime. Here, we respond to the Australian Government Treasury consultation on the Petroleum Resource Rent Tax (PRRT) – anti-avoidance provisions and clarifying treatment of ‘exploration’ and Mining, Quarrying or Prospecting Rights.

COP28 initiatives will only reduce emissions if followed through

Few of the sectoral initiatives announced during COP28 will meaningfully contribute to closing the emissions gap. Many of them lack either the ambition, clarity, coverage or accountability needed to really make a difference.

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.

Submission on Australia's future gas strategy

The Australian government asked for answers to its questions around the future of its gas strategy. This was our submission.

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.

State of Climate Action 2023

This report finds that global efforts to limit warming to 1.5°C are failing across the board, with recent progress made on every indicator – except electric vehicle sales – lagging behind the pace and scale needed to address the climate crisis.

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.
