António Guterres says ‘sun is rising on a clean energy age’ as 90% of renewable power projects cheaper than fossil fuels
Rapporteur calls for defossilization of economies and urgent reparations to avert ‘catastrophic’ rights and climate harms
Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehend
Identifying the socio-economic drivers behind greenhouse gas emissions is crucial to design mitigation policies. Existing studies predominantly analyze short-term CO2 emissions from fossil fuels, neglecting long-term trends and other GHGs. We examine the drivers of all greenhouse gas emissions between 1820–2050 globally and regionally. The Industrial Revolution triggered sustained emission growth worldwide—initially through fossil fuel use in industrialized economies but also as a result of agricultural expansion and deforestation. Globally, technological innovation and energy mix changes prevented 31 (17–42) Gt CO2e emissions over two centuries. Yet these gains were dwarfed by 81 (64–97) Gt CO2e resulting from economic expansion, with regional drivers diverging sharply: population growth dominated in Latin America and Sub-Saharan Africa, while rising affluence was the main driver of emissions elsewhere. Meeting climate targets now requires the carbon intensity of GDP to decline 3 times faster than the global
Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online [...] The report recommended that if global red meat eating was cut by 50%, the “planetary health diet” would provide nutritious food to all while tackling the harms caused by animal agriculture, which accounts for over 14% of all greenhouse gas emissions worldwide. It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.
Dans le cadre de la transition énergétique, l’aviation se tourne vers des e-fuels nécessitant des volumes importants d’électricité bas carbone pour être produits. Or, cette électricité est bien moins taxée que l’électricité destinée à des besoins « primaires », tels que le chauffage ou l'éclairage, comme le détaille mon étude publiée dans Climate Policy(1).
As fossil fuel interests attack climate accountability litigation, environmental advocates have sounded a new warning that they are pursuing a path that would destroy all future prospects for such cases. Nearly 200 advocacy groups have urged Democratic representatives to “proactively and affirmatively” reject potential industry attempts to obtain immunity from litigation.
Climate change will fuel contests—and maybe wars—for land and resources.
The world’s addiction to fossil fuels is a “Frankenstein’s monster sparing nothing and no one”, the UN secretary general, António Guterres, told leaders at the World Economic Forum in Davos on Wednesday. “Our fossil fuel addiction is a Frankenstein’s monster, sparing nothing and no one. All around us, we see clear signs that the monster has become master,”
Un armateur norvégien a annoncé avoir modifié un de ses navires pour en faire "le premier au monde" doté à bord d'un système de captage et de stockage du CO2 à grande échelle afin de réduire ses émissions.Alimenté au fioul lourd, un carburant décrié pour ses émissions élevées de soufre, particules fines et dioxyde de carbone, le Clipper Eris devrait voir ses rejets de gaz à effet de serre (GES) réduits de jusqu'à 70%, a indiqué son propriétaire, le groupe Solvang.
As Malm and Carton explain, if firm policies were put in place to “leave fossil fuels in the ground”, stranding the assets of fossil fuel companies, there would be “layer upon layer” of value destruction.
It’s better to burn out than fade away…until it kills you.

2024

COP29 in Baku, which finished last week, was crawling with fossil-fuel lobbyists determined to eke out profits for as long as possible. Shockingly, for a second year running, it is European governments that have facilitated access for a huge number of them.
At least 1773 fossil fuel lobbyists have been granted access to the COP29 summit in Baku, underscoring an outsized polluter presence year after year at crucial climate talks, according to a new analysis from Corporate Europe Observatory, Corporate Accountability and Global Witness, from the Kick Big Polluters Out (KBPO) coalition.
Global average surface temperatures shattered all-time records in 2023 at 1.45 ± 0.12 ◦C above pre- industrial levels (WMO 2024). Worsened by climate change-induced drought, Canadian wildfires burned 18.5 million hectares, nearly three-times more land area than in any previous year on record (NRC 2023).
The net zero approach of the Paris agreement has become detached from reality as it increasingly relies on science fiction levels of speculative technology.
Alors que les gouvernements se préparent à se réunir pour le Sommet du Futur de septembre prochain - une réunion de haut niveau des Nations Unies qui vise à "offrir un meilleur présent et à préserver l'avenir" - de récentes négociations ont supprimé deux mots du projet de résultat : les combustibles fossiles.
En tant qu'anciens chefs de gouvernement et lauréats du prix Nobel du monde entier, nous écrivons avec un sentiment commun d'urgence et de responsabilité concernant l'avenir de notre planète. Nous félicitons les Nations unies pour leur intention d'organiser un Sommet de l'avenir en septembre prochain - une réunion historique des Nations unies qui vise à garantir un avenir durable et équitable pour tous.
Coal and gas exports expected to remain roughly at current level until at least 2035 with 4.5% of emissions linked to Australia, report finds
Le plus gros parti au Parlement européen désire revoir la mesure concernant l'interdiction des moteurs thermiques dès 2035.
