Global CO2 emissions from fossil fuels reached a record high in 2024 at 37.4 billion tonnes, up 0.8% from 2023, according to the Global Carbon Project. Despite progress in renewables and climate efforts, fossil fuel use has not yet peaked, raising concerns about reaching global warming limits. With 41.6 billion tonnes of CO2 projected overall, scientists stress immediate and deep emission cuts to meet climate targets and prevent further warming. Key regions show mixed trends, with India’s emissions up 4.6% and the EU’s emissions down 3.8%.

India accounts for per cent of the global total carbon dioxide (CO2) emissions, and it is expected to increase by 4.6 per cent in 2024, according to a new report released on Wednesday, ahead of the UN climate conference in Baku, Azerbaijan.

Cargo bikes save an average of 95 percent and 82 percent more carbon dioxide equivalent (CO2e) per kilometre than diesel vans and electric vans respectively, according to findings from UK cargo bike delivery network Zedify.

While existing travel websites primarily display the cheapest or fastest travel option, the new BookSmart24 app also finds the most CO2- and emission-efficient variant for the chosen route. The platform enables users to make smart and responsible booking decisions and to realize that traveling in an environmentally conscious manner does not necessarily have to be more expensive.

Transition-metal nitro­gen-doped carbons (TM-N-C) are emerging as a highly promising catalyst class for several important electrocatalytic processes, including the electrocatalytic CO2 reduction reaction (CO2RR). The unique local environment around the singly dispersed metal site in TM-N-C catalysts is likely to be responsible for their catalytic properties, which differ significantly from those of bulk or nanostructured catalysts. However, the identification of the actual working structure of the main active units in TM-N-C remains a challenging task due to the fluctional, dynamic nature of these catalysts, and scarcity of experimental techniques that could probe the structure of these materials under realistic working conditions. This issue is addressed in this work and the local atomistic and electronic structure of the metal site in a Co–N–C catalyst for CO2RR is investigated by employing time-resolved operando X-ray absorption spectroscopy (XAS) combined with advanced data analysis techniques. This multi-step approach, based on principal component analysis, spectral decomposition and supervised machine learning methods, allows the contributions of several co-existing species in the working Co–N–C catalysts to be decoupled, and their XAS spectra deciphered, paving the way for understanding the CO2RR mechanisms in the Co–N–C catalysts, and further optimization of this class of electrocatalytic systems.

BAKU — Global carbon dioxide emissions, including those from burning fossil fuels, are set to hit a record high this year, pulling the world further off course from averting more destructive climate extremes, scientists said on Wednesday (Nov 13). The Global Carbon Budget report, published during the UN's COP29 climate summit in Azerbaijan, said global CO2 emissions are set to total 41.6 billion metric tons in 2024, up from 40.6 billion tons last year. The bulk of these emissions are from burning coal, oil and gas. Those emissions would total 37.4 billion tons in 2024, up by 0.8 per cent in 2023, the report said. The rest are from land use, a category that includes deforestation and forest fires. The report by more than 80 institutions was led by the University of Exeter in UK. "We don't see a sign of fossil fuel emissions peaking in 2024," said lead author Pierre Friedlingstein, a climate scientist at the University of Exeter. Without immediate and steep emissions cuts worldwide, "we will just go straight into the 1.5C target, we'll just pass it and continue," he said.
