In 2023, the CO2 growth rate was 3.37 ± 0.11 ppm at Mauna Loa, 86% above the previous year, and hitting a record high since observations began in 1958[1], while global fossil fuel CO2 emissions only increased by 0.6 ± 0.5%[2,3]....
Offsetting allows corporations to increase emissions, while getting credit for pseudo-reductions elsewhere
A carbon bomb is any fossil fuel extraction project that will generate more than one gigatonne of carbon dioxide (1GtCO2) over its remaining life.

Carbon Brief provides an updated analysis of when the world will likely exceed the Paris 1.5C limit
Historical responsibility for climate change is radically shifted when colonial rule is taken into account, Carbon Brief analysis reveals.
Natural ecosystems store large amounts of carbon globally, as organisms absorb carbon from the atmosphere to build large, long-lasting, or slow-decaying structures such as tree bark or root systems. An ecosystem’s carbon sequestration potential is tightly linked to its biological diversity. Yet when considering future projections, many carbon sequestration models fail to account for the role biodiversity plays in carbon storage. Here, we assess the consequences of plant biodiversity loss for carbon storage under multiple climate and land-use change scenarios. We link a macroecological model projecting changes in vascular plant richness under different scenarios with empirical data on relationships between biodiversity and biomass. We find that biodiversity declines from climate and land use change could lead to a global loss of between 7.44-103.14 PgC (global sustainability scenario) and 10.87-145.95 PgC (fossil-fueled development scenario). This indicates a self-reinforcing feedback loop, where higher levels

China’s CO2 emissions fell by 3% in March 2024, ending a 14-month surge that began when the economy reopened after the nation’s “zero-Covid”

Over the past year, there has been a vigorous debate among scientists – and more broadly – about whether global warming is “accelerating”.
Carbon Brief explores which countries are or have targets to be net-negative, and the moral and scientific arguments for such a milestone.

Global investment in the clean energy transition grew by 17% in 2023, showing resilience despite geopolitical tensions, high interest rates, and inflation. But was it enough to keep the world on track to hit net zero by 2050? To answer this question, we compare 2023 clean energy investment by sector with what’s annually needed to reach net zero by 2050, in partnership with the National Public Utilities Council.
Current methods to calculate the so-called social cost of carbon largely leave out how many future people our emissions will kill. This study tries to correct that.

EUCityCalc has officially launched its free, open source online platform that allows local councils and other stakeholders to visualise and simulate low-carbon scenarios for their towns and cities, as well as to assess the trade-offs related to available choices.
The European Commission has received an open letter signed by 110 academics, businesses, civil society organisations and research institutions urging the EU to separate emissions reductions, land-based sequestration and permanent carbon removals in the EU’s post-2030 climate framework. This separation should be at the heart of both the setting and the implementation of the 2040 target and associated plans.
At a time when we need to shift our collective climate action up a gear, the influence of the fossil fuels lobby is succeeding in slowing down ambition both at COP27 and in the EU.

The critical annual update revealing the latest trends in global carbon emissions
The effect of increasing the concentration of atmospheric carbon dioxide (CO2) on global average surface air temperature might be expected to be constant, but this is not the case. A study published in the journal Science shows that carbon dioxide becomes a more potent greenhouse gas as more is released into the atmosphere.

Mapped: Carbon Dioxide Emissions Around the World According to Our World in Data, the global population emits about 34 billion tonnes of carbon dioxide (CO₂) each year. Where does all this CO₂ come from? This graphic by Adam Symington maps out carbon emissions around the world, using 2018 data from the European Commission that tracks tonnes of CO₂ per 0.1 degree grid (roughly 11 square kilometers). This type of visualization allows us to clearly see not just population centers, but flight paths, shipping lanes, and high production areas. Let’s take a closer look at some of these concentrated (and brightly lit) regions on the map.

Human activities are threatening to push the Earth system beyond its planetary boundaries, risking catastrophic and irreversible global environmental change. Action is urgently needed, yet well-intentioned policies designed to reduce pressure on a single boundary can lead, through economic linkages, to aggravation of other pressures. In particular, the potential policy spillovers from an increase in the global carbon price onto other critical Earth system processes has received little attention to date. To this end, we explore the global environmental effects of pricing carbon, beyond its effect on carbon emissions. We find that the case for carbon pricing globally becomes even stronger in a multi-boundary world, since it can ameliorate many other planetary pressures. It does however exacerbate certain planetary pressures, largely by stimulating additional biofuel production. When carbon pricing is allied with a biofuel policy, however, it can alleviate all planetary pressures. In the light of nine Earth Syst
We are developing a first-of-a-kind methodology for transforming industrial sabotage and other forms of direct action into carbon offsets. Browse our repository of case studies or propose a new one for analysis.

A new paper suggests that variations in warming of the Pacific Ocean were actually triggered by changing aerosol emissions from human activity.
Poly- and perfluoroalkyl substances (PFAS) and global climate change have attracted worldwide attention. PFAS have been found all across the planet, from the polar regions to the global ocean. Global oceans have emerged as a substantial sink for the carbon in the environment due to their remarkable capacity to absorb atmospheric carbon. Oceans absorb around 24% of the world’s CO2 emissions. Thus, the ocean plays a prominent role in the earth’s carbon cycle. However, the widespread application of PFAS in a wide range of products and the inefficient management of PFAS-containing wastes made them ubiquitous pollutants, which are increasingly getting as a pollutant of emerging concern. Marine PFAS pollutants can produce harmful effects on gas exchange and the ocean’s carbon cycle. Thus, it leads to an increase in greenhouse gas emissions, which eventually adversely affects global warming and climate change. Consequently, threats of marine PFAS to oceans carbon sequestration are discussed in this paper. Marine PFA

Hopes of the UK government meeting its domestic and international climate targets have “worsened” over the past year, according to the CCC.
Almost every country in the world has signed up to the Paris Agreement’s goal of keeping warming well-below 2C and pursuing efforts to limit it to 1.5C.

Popularity of sport utility vehicles driving higher oil demand and climate crisis, say experts
Potential external cost savings associated with the reduction of animal-sourced foods remain poorly understood. Here we combine life cycle assessment principles and monetarization factors to estimate the monetary worth of damage to human health and ecosystems caused by the environmental impacts of food production. We find that, globally, approximately US$2 of production-related external costs were embedded in every dollar of food expenditure in 2018—corresponding to US$14.0 trillion of externalities. A dietary shift away from animal-sourced foods could greatly reduce these ‘hidden’ costs, saving up to US$7.3 trillion worth of production-related health burden and ecosystem degradation while curbing carbon emissions. By comparing the health effects of dietary change from the consumption versus the production of food, we also show that omitting the latter means underestimating the benefits of more plant-based diets. Our analysis reveals the substantial potential of dietary change, particularly in high and upper-
Only if there is a fundamental change in the way we manage land we can reach the targets of climate-change mitigation, avert the dramatic loss of biodiversity and make the global food system sustainable.
