National action on climate change mitigation appears to be joining the international climate negotiations in the new and ever popular “climate shuffle” dance. It involves maximum effort and motion while staying in the same spot…or even, in some cases, going backwards.

Recent emissions trends and estimates of the effects of those policies in place and proposed lead to a new estimate that warming is likely to approach 4°C by 2100, significantly above the warming that would result from full implementation of the pledges (3.3°C). The continuous global fossil-fuel intensive development of the past decade suggests that high warming levels of 4°C are more plausible than assuming full implementation of current pledges.

Climate Action Tracker: 2024 warming projection update

Despite an escalating climate crisis marked by unprecedented wildfires, storms, floods, and droughts, the Climate Action Tracker annual global temperature update shows global warming projections for 2100 are flatlining, with no improvement since 2021. The aggregate effect of current policies set the world on a path toward 2.7°C of warming.

Decarbonising light-duty vehicle road transport

The Climate Action Tracker provides updated 1.5ºC compatible benchmarks for the transport sector for the world as a whole and for seven individual countries; the US, EU, China, India, Brazil, South Africa and Indonesia.

Emissions Gap Report 2024: No more hot air … please!

The 2024 edition of UNEP’s Emissions Gap Report shows how much higher nations must aim. To get on a least-cost pathway for 1.5°C, emissions must fall 42 per cent by 2030, compared to 2019 levels. G20 nations, particularly the largest-emitting members, would need to do the heavy lifting.

The role of northern forests in limiting warming to 1.5°C

Northern forests are critical in the race to net zero CO₂ by mid-century. Protecting and restoring these forests, alongside steep and rapid reductions in fossil fuel emissions, is essential both to mitigating emissions and to supporting forest ecosystem services and biodiversity.

Methodology underpinning the State of Climate Action series: 2024 update

This technical note describes the State of Climate Action series’ methodology for identifying sectors that must transform, translating these transformations into global mitigation targets primarily for 2030, 2035 and 2050 and selecting indicators with datasets to monitor annual change. It also outlines the report’s approach for assessing progress made toward near-term targets and comparing trends over time.

LNG shipbuilding industry heading to huge oversupply

The LNG shipbuilding industry appears to be doubling down on building new carriers, ignoring the global shift to a low carbon economy and putting itself into an even worse oversupply situation than a year ago, we find in our updated report.

Setting 1.5°C compatible wind and solar targets

Based on global energy system modelling sense-checked against key national studies, this report presents new analysis on what a 1.5°C-aligned rollout of wind and solar could look like for key countries. It aims to inform target setting for 2030, 2035 and beyond in third generation NDCs.

Technical guide for the development of long-term low emission development strategies in Africa

This technical guide proposes concrete steps and actions to help African countries develop strong, high-performing Long-Term Low Emission and Climate Resilient Development Strategies that chart a low-emission development path, build resilience, encourage innovation, and create new opportunities for green growth.

Evaluating the near and long-term role of carbon dioxide removal in meeting global climate objectives

For 1.5°C pathways with limited overshoot, most of the mitigation between now and 2030 should come from emissions reductions (70%), with reductions from cutting non-CO2 emissions (20%) and land-based carbon dioxide removals such as afforestation and preventing deforestation (10%) making up the remainder.

Article 6.4 progress update: work of the Supervisory Body on the Paris Agreement Crediting Mechanism

The Article 6.4 mechanism, now known as the Paris Agreement Crediting Mechanism, allows countries to trade reductions in carbon emissions in a manner that goes beyond zero-sum offsetting, to achieve their commitments under the Paris Agreement. This briefing aims to update Small Island Developing States and Least Developed Countries on the standards and procedures that have been adopted by the supervising body (Article 6.4) to inform the design of projects.

What does a just transition look like for Caribbean Small Island Developing States?

This briefing aims to provide some preliminary information on what just transition encompasses in the context of Caribbean Small Island Developing States.

What good looks like: G7 climate policy 2024 update

This brief outlines seven key policy recommendations for this June’s G7 summit that, if adopted, would demonstrate the ambition and leadership needed to keep the Paris Agreement’s 1.5°C limit in sight.
