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.

As authorities declared 2024 the hottest on record, a key private sector climate alliance, the Glasgow Financial Alliance for Net Zero (GFANZ) abandoned a requirement that members be aligned to the Paris agreement. That was followed by a network of net zero asset managers suspending work, and deleting from its website its statement of commitments that members must adopt, after BlackRock, the biggest of them all, quit its ranks.
Shifting responsibility to consumers minimises the role of energy industry and policymakers, University of Sydney research suggests

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.

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

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

novembre 2022

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.

In this 2nd part we use data from the BP Statistical Review (June 2020). BP’s definition of oil is different from OPEC’s crude oil used in part 1. It includes also shale oil, oil sands, condensates (lease condensate or gas condensates that require further refining) and NGLs (natural gas liquids – ethane, LPG and naphtha separated from the production of natural gas).

novembre 2021

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

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.

juin 2021

Every new climate pledge is an attempt to distract people from the failed ones it replaces. Apparently, all seven governments have committed “to conserve or protect at least 30 per cent of the world’s land and at least 30 per cent of the world’s ocean by 2030”. But what does it mean?

mai 2021

The number of countries announcing pledges to achieve net zero emissions over the coming decades continues to grow. But the pledges by governments to date – even if fully achieved – fall well short of what is required to bring global energy-related carbon dioxide emissions to net zero by 2050 and give the world an even chance of limiting the global temperature rise to 1.5 °C.
