Carbon Emissions

Calling for strategies to tackle residual emissions, scientists said they would need to be balanced by carbon dioxide removal techniques to meet net-zero goals, meaning that greenhouse gases (GHG) entering the atmosphere are offset by those being removed. Residual emissions are those that remain after efforts to eliminate GHG emissions have been implemented. For example, agriculture and shipping industries are likely to continue releasing GHG in the atmosphere, even with concerted efforts towards eliminating emissions. "Our plans are not adequate to meet the goal of limiting the earth's temperature increase to no more than 1.5 degrees Celsius by 2050," said lead researcher Holly Jean Buck, assistant professor of environment and sustainability, University of Buffalo, New York, US. Buck and her international team argued for a better understanding of residual emissions in their paper published in the journal Nature Climate Change. They said that according to long-term strategies of ..

Following certain recommendations such as using steel frames and opting for tile cladding in multi-storey building design to decrease embodied carbon emissions and operational energy could save up to six gigatonnes of carbon by 2050, according to a new study. Researchers from the University of Cambridge and Bath, UK, devised a computer model and used it to estimate that these recommendations could also save between 28 and 44 per cent of annual heating and cooling costs, using technology that is currently available. Their findings are reported in the journal Applied Energy. Construction and operation of buildings account for more than one-third of global emissions and energy use. While buildings are a large part of the current problem, they are also a significant lever for change, said the researchers. For their study, the researchers looked at shape, size, layout, structural system, windows, insulation, ventilation, and use parameters, for both residential and office buildings, acr

Publication of a major new United Nations report on climate change is being held up by a battle between rich and developing countries over emissions targets and financial aid to vulnerable nations. The report by hundreds of the world's top scientists was supposed to be approved by government delegations Friday at the end of a weeklong meeting in the Swiss town of Interlaken. The deadline was repeatedly extended as officials from big nations such as China, Brazil, Saudi Arabia, as well as the United Nations and the European Union haggled through the weekend over the wording of key phrases in the text. The report by the United Nations' Intergovernmental Panel on Climate Change is meant to cap a series that digests vasts amounts of research on global warming compiled since the Paris climate accord was agreed in 2015. A summary of the report was approved early Sunday, but three sources close to the talks have told The Associated Press that there is a risk that agreement on the main tex

India's nuclear power sector is saving 41 million tonnes of carbon dioxide emissions annually, compared to emissions that would have been generated by equivalent electricity generation from coal-based thermal power plants, Union Minister Jitendra Singh informed Lok Sabha on Wednesday. In a written reply, Singh said as part of low carbon development of electricity systems consistent with enhanced development benefits, the government was exploring a significantly greater role for nuclear power. Nuclear power currently comprises three per cent of India's total electricity generation, Singh said, adding that sufficient production and share of atomic energy was essential for ensuring the country's energy security. Current policy targets a three-fold rise in nuclear installed capacity by 2032, said Singh, who is in-charge of the Department of Atomic Energy. He said nuclear energy can be considered for delivering base load power free of intermittency in place of energy from fossil ...

The carbon emissions from the Indian marine fisheries sector is much lower than the global level, an ICAR-Central Marine Fisheries Research Institute (CMFRI) research study said. Presenting the data at a review meeting of the fisheries component of the network research project under the National Innovations in Climate Resilient Agriculture (NICRA) of the Indian Council of Agricultural Research (ICAR), CMFRI found that the harvest phase (active fishing) in the country utilised more than 90 per cent of the fuel used in the sector. In a research in assessing the carbon footprint in India's marine fisheries, the ICAR-CMFRI has estimated that the sector emits 1.32 tonnes of CO2 (carbon dioxide) to produce one tonne of fish, which is lower than the global average of more than two tonnes for the same quantity. "This is the assessment of the greenhouse gas (GHG) emissions from total activities in the sector, from pre-harvesting to marketing, by converting it into CO2 equivalent," CMFRI said

Suzuki Motorcycle India on Wednesday said it has launched a range of scooters, which conform with the upcoming stricter emission norms, priced between Rs 79,400 to Rs 97,000 (ex-showroom Delhi). The company's 125cc scooters, including Access 125, Avenis and Burgman Street, get the latest on-board diagnostics (OBD2-A) system. Suzuki has also introduced E20 fuel-compliant engines on the Access 125, Avenis and Burgman Street range. "Suzuki's powerful 125cc engine which delivers high performance and has been ruling riders' hearts is now E20 (petrol with 20 per cent ethanol) and OBD2-A compliant. We plan to gradually make our entire product portfolio compatible to E20 fuel," Suzuki Motorcycle India Executive Vice President (Sales, Marketing and After Sales) Devashish Handa said in a statement.

A study, implemented in 2020-21, included 21 businesses, representing about 10% of industry emissions, and all elements of a carbon market demonstrated a 28% reduction in cost of emissions reductions

Ever bigger cars pose a growing problem for the environment because they produce more greenhouse gas emissions and need larger batteries than their smaller cousins, according to the International Energy Agency. The Paris-based body suggested Monday that it's time for the car industry to downsize its vehicles, citing data that showed the world's 330 million sports utility vehicles, or SUVs, pumped out almost 1 billion metric tons of carbon dioxide in 2022. That's more than the annual emissions of an industrial nation like Germany. The shift towards heavier and less fuel-efficient conventional vehicles increases growth in both oil demand and CO2 emissions," the agency said, noting that SUVs consume about a fifth more gasoline than an average medium-sized car. Between 2021 and 2022, oil use in conventional cars, excluding SUVs, remained roughly the same, but the oil consumption of SUVs globally increased by 500,000 barrels per day, accounting for one-third of the total growth in oil .

Researchers have shown that a new 3D-printed superalloy could help power plants generate more electricity while producing less carbon, according to a new study. Scientists from Sandia National Laboratories, US, created a superalloy, with an unusual composition that makes it stronger and lighter than state-of-the-art materials currently used in gas turbine machinery, the study said. A superalloy, or a high-performance metal alloy, is an alloy with the ability to operate at a high fraction of its melting point. As the world looks for ways to cut greenhouse gas emissions, the findings could have broad impacts across the energy sector as well as the aerospace and automotive industries, and hints at a new class of similar alloys waiting to be discovered, the study said. The team published their findings in the journal Applied Materials Today. "We're showing that this material can access previously unobtainable combinations of high strength, low weight and high-temperature resiliency,"
