This Climate Action Tracker Update uses a new method to assess “comparable efforts” and the “fair share” of governments’ national greenhouse gas reduction proposals. Such a comparison is essential for the successful completion of an agreement on climate change in Paris in December this year, as some governments have made their offers conditional on comparable action by others.
For the first time, the method we have developed provides a comprehensive overview of many different viewpoints on what could be considered a “fair” contribution for each of over 30 countries, and for the periods 2020, 2025, 2030 and 2050. It is based on a very wide range of literature from researchers from the north and south that was initially collected for the IPCC Fifth Assessment Report (AR5).
The Climate Action Tracker does not itself assign emission reduction proposals of countries to a specific concept of “fairness”, but instead locates a country’s emission proposals within the full range of academic analyses of the issue. The “sufficient” category means that if all governments adopted the same level of effort, warming would be held below 2°C with a likely probability.
Where a government is rated “medium”, its emission reduction proposals could be compatible with limiting warming below 2°C, but only if other countries compensated for that by reducing their emissions more than their medium category.
In order to span the full range of literature, the Climate Action Tracker’s team—from four research organisations—has complemented IPCC AR5 with new literature, alongside the CAT’s own, new calculations.
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.
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.
Railway development: lessons for the EU
This paper analyses how EU railway policy for a low-carbon future can be enhanced, drawing insights from Japan and Switzerland.
2030 targets aligned to 1.5°C: evidence from the latest global pathways
Our new method applies sustainability limits and minimises the need for carbon dioxide removal to set key 2030 global targets for renewables, fossil fuels and emissions.
The biogeophysical effects of idealised land cover and land management changes in Earth system models
The dependence of different land cover and land management change options on the background climate are still poorly understood across different Earth system models.
