AI model recommendation framework could slash machine learning selection emissions by 98% -study
A new academic study has proposed a machine learning recommendation framework designed to minimise carbon emissions from AI model development by predicting the environmental impact of training runs before they occur, with the researchers claiming the approach could cut emissions from model selection by more than 98%.

A bipartisan US proposal to expand reforestation infrastructure support could ease long-standing supply bottlenecks constraining nature and carbon projects, observers told Carbon Pulse.
Read MoreLess than 2% of global cement emissions set to be captured by 2035, report finds
Planned CO2 capture and storage (CCS) projects in the cement sector will capture less than 2% of the industry’s global emissions by 2035, despite the successful launch last year of the world’s first commercial‑scale CCS facility at a Norwegian cement plant, according to a new report.
Read MoreBRIEFING: Financiers single out ‘delivery risk’ as biggest obstacle for European carbon removal projects
The risk that a developer goes bankrupt or fails to deliver is the biggest obstacle to funding carbon removal (CDR) projects, financiers told a European Commission event on the EU’s Carbon Removals and Carbon Farming (CRCF) scheme last week.
Read MoreGlobal carbon removal “governance gap” threatens climate goals, report warns
A new discussion paper has urged governments to rapidly establish a global governance framework for carbon removal (CDR), warning that the world is dangerously unprepared to manage the scale needed to meet climate targets.
Read MoreArticle 6 authority adopts new clean cooking fNRB tool, requests additional country-level values
The Article 6.4 Supervisory Body (SBM) has formally adopted a new tool for calculating the fraction of non-renewable biomass (fNRB), a key parameter underpinning baseline-setting in cookstove and biomass carbon activities, though has requested more granular country-level values be included following further work.
Read MoreMarine carbon removal projects may gain from persistent sargassum blooms -report
Marine carbon removal (mCDR) projects looking to use sargassum could benefit from more predictable and persistent blooms in the Atlantic, as floating seaweed mats have increasingly begun to sustain their own growth, according to a recent study.
Read MoreMethane emissions from global rice paddies surge as soil carbon sink weakens -study
Global greenhouse gas emissions from rice paddies have nearly doubled over the past six decades, driven primarily by expansion in cultivated area and intensified crop residue incorporation, with methane remaining by far the dominant source of warming, according to a new study.

Emitters and financial players appear on opposite sides of the fence following the latest US Commodity Futures Trading Commission (CFTC) reference period, with each shortening and lengthening their positions, respectively for overall net holdings in California Carbon Allowances (CCAs) and RGGI Allowances (RGAs), data showed.
Read MoreOcean CDR initiative funds studies into alkalinity enhancement impacts on fisheries, marine species
An ocean carbon removal research initiative has awarded funding to two scientific projects examining how ocean alkalinity enhancement (OAE) could affect commercially and culturally important marine species, amid growing scrutiny over the ecological risks of marine CO2 removal techniques.
