Under current emission trajectories, temporarily overshooting the Paris global warming limit of 1.5 °C is a distinct possibility. Permanently exceeding this limit would substantially increase the probability of triggering climate tipping elements. Here, we investigate the tipping risks associated with several policy-relevant future emission scenarios, using a stylised Earth system model of four interconnected climate tipping elements.

Met ruim honderd biljoen dollar aan vermogen is de Glasgow Financial Alliance for Net Zero op papier de machtigste financiële organisatie ter wereld. Het doel is om klimaatneutraal te worden tegen 2050. Maar tussen woord en daad gapen belangen in de fossiele industrie en conservatieve lobbygroepen.

L'Institutional Investors Group on Climate Change (IIGCC) a publié une nouvelle version de son Net Zero Standard for Oil and Gas.

Without more legally binding and well-planned net-zero policies, the world is highly likely to miss key climate targets.

Humanity is not on track to avoid the deadliest effects of climate change, according to University at Buffalo researcher Holly Jean Buck. "Our plans are not adequate to meet the goal of limiting the Earth's temperature increase to no more than 1.5℃ by 2050," said Buck, Ph.D., assistant professor of environment and sustainability....

Carbon offsets can help achieve emissions goals, some experts argue, while others say they are actively dangerous

Many countries' pledges to get to net zero greenhouse gas emissions rely partly on removing carbon dioxide from the atmosphere, using methods such as planting trees and restoring degraded ecosystems. But a report out today has revealed they are relying too heavily on these carbon drawdown schemes to fulfil these promises. The Land Gap Report, which was released today by the University of Melbourne and includes input from more than 20 international researchers, has calculated countries would collectively need 1.2 billion hectares of land to meet their Paris Agreement goals.

Carbon capture and storage schemes, a key plank of many governments’ net zero plans, “is not a climate solution”, the author of a major new report on the technology has said. Researchers for the Institute for Energy Economics and Financial Analysis (IEEFA) found underperforming carbon capture projects considerably outnumbered successful ones by large margins.

They argue that balancing supply represents just a fraction of nuclear power’s potential contribution to decarbonisation.

Net zero is popular among polluters for good reason – it’s toothless compared to emissions restrictions and a carbon tax

In Paris, all governments solemnly promised to come to COP26 with more ambitious 2030 commitments to close the massive 2030 emissions gap that was already evident in 2015. Three years later the IPCC Special Report on 1.5°C reinforced the scientific imperative, and earlier this year it called a climate “code red.” Now, at the midpoint of Glasgow, it is clear there is a massive credibility, action and commitment gap that casts a long and dark shadow of doubt over the net zero goals put forward by more than 140 countries, covering 90% of global emissions.

Low greenhouse gas technologies require more metals than their fossil fuel-based counterparts. This column estimates supply elasticities and pins down the price impact of the energy transition on the metals markets. The results show that prices for copper, nickel, cobalt, and lithium could reach historical peaks for an unprecedented, sustained period in a net zero emissions scenario. The total value of production could rise more than four-fold for the period 2021-2040, rivaling the total value of crude oil production.

To successfully emerge from Covid into a fairer, greener future we need to recognise nature as an essential piece of the puzzle

Fresh emissions targets from Saudi Arabia and Australia – two of the world’s largest fossil-fuel producers – are due to arrive just in time for global climate talks in Glasgow. These would commit the two countries to reducing domestic emissions to net zero by around mid-century – though both are expected to continue exporting fossil fuels for decades to come.

pour enrayer les pires scénarios en matière de changement climatique, les émissions mondiales de gaz à effet de serre devront diminuer de moitié d’ici à 2030, avant de descendre au niveau net nul vers le milieu du siècle. En clair, il s’agit d’éliminer de l’atmosphère, par des moyens technologiques ou naturels, toutes les émissions de CO2 liées aux activités humaines dans le but de parvenir à « zéro émission nette », c’est-à-dire à la neutralité carbone. Dans son rapport intitulé Net Zero by 2050, l’Agence internationale de l’énergie (AIE) tire la sonnette d’alarme quant à la nécessité de limiter la part des combustibles fossiles dans la consommation d’énergie. La feuille de route présentent des scénarios concrets de transition

Governments must close gap between net zero rhetoric and reality, says International Energy Agency head

The best available evidence shows that, on the contrary, warming is likely to more or less stop once carbon dioxide (CO2) emissions reach zero, meaning humans have the power to choose their climate future.
