Purpose Animal emissions account for nearly 60% of total greenhouse gas emissions from the livestock sector. To estimate these emissions, the Food and Agriculture Organization of the United Nations (FAO) developed a dedicated module within the Global Livestock Environmental Assessment Model (GLEAM). Although previous studies have explored selected inputs for specific animals and emission types, a comprehensive analysis of all 92 inputs (parameters and emission factors) had not been conducted. This study aimed to identify the most influential inputs affecting ruminant emissions in GLEAM.

This article examines the technocentric bias that characterizes climate mitigation literature, focusing on the reports of the IPCC's Working Group III. This bias stems from structural features of the scientific field that prioritizes innovation, leading to the overrepresentation of technological solutions in climate research. Funding mechanisms further reinforce this tendency by incentivizing collaboration with industrial R&D, creating a self-reinforcing loop in which scientific authority and industrial interests converge. The IPCC's institutional positioning—as a policy-relevant yet politically cautious body—amplifies this dynamic by favoring allegedly “cost-effective” technological pathways that lack practical feasibility.

Consumers ending up shouldering most of the costs of installing and operating CCS in the UK, a new report has found.
The startup Gigablue announced with fanfare this year that it reached a historic milestone: selling 200,000 carbon credits to fund what it describes as a groundbreaking technology in the fight against climate change . But outside scientists frustrated by the lack of information released by the company say serious questions remain about whether Gigablue’s technology works as the company describes. Their questions showcase tensions in an industry built on little regulation and big promises — and a tantalizing chance to profit.

A new study uncovers Earth’s deep temperature history and shows just how tightly carbon dioxide has always controlled the climate

Climate activists opposed to the Mountain Valley pipeline were accused of breaking West Virginia’s new critical infrastructure law
The EU is being sued for failing to set ambitious climate targets in sectors that contribute more than half of the bloc’s total greenhouse gas emissions.

juin 2024

Annually updated, IPCC AR6 consistent indicators of human-induced global warming, greenhouse gas emissions, and the remaining global carbon budget.

mars 2024

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.

novembre 2023

Global fall averaged 4.2% between 2010 and 2022 but would have been far more if vehicle sizes stayed same

août 2023

More than a century of research shows that burning fossil fuels warms the climate – that’s exactly why granting new North Sea oil and gas licenses is a bad idea.

juillet 2023

Energy firms have made record profits by increasing production of oil and gas, far from their promises of rolling back emissions

avril 2023

The total concentration of greenhouse gases and other forcing agents, including cooling aerosols, reached 465 parts per million CO2 equivalents in 2020. This is around the peak level that the International Panel on Climate Change states 'should not be exceeded if — with a 67% likelihood and not allowing a temperature overshoot — the global temperature increase is to be limited to 1.5oC above pre-industrial levels'. When allowing for a temperature overshoot, the peak level could be exceeded in 2024. The peak concentrations corresponding to a temperature increase of 2oC by 2100 could be exceeded between 2027 and 2030.

Carbon credits and offsets do not have a great record but the funds they raise are a vital part in fight against deforestation

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.
National climate pledges would collectively require 1.2 billion hectares (about 3 billion acres) of land, researchers have found in a new study, The Land Gap Report. More than half of this land is already currently used for something else. This demand for land will put pressure on ecosystems, Indigenous lands, small farmers and food security. Protecting existing forests and securing Indigenous and community land rights are more effective than carbon capture plans requiring land-use change, including reforestation.
Scientists warn world ‘is heading in wrong direction’ amid rise in nitrous oxide, carbon dioxide and methane.Atmospheric levels of all three greenhouse gases have reached record highs, according to a study by the World Meteorological Organization, which scientists say means the world is “heading in the wrong direction”.
