Carbon Dioxide

Steel is responsible for 7% of global carbon dioxide emissions, around the same as India, with coal-fired blast furnaces producing 2 metric tons of CO2 for each ton of output

The unfairness in the allocation of responsibility for controlling CO2 emissions is evident in the shifting of the burden of emission reductions from consumers to producers

The study claims that Earth's continents are drifting and will one day form a single supercontinent. This will be accompanied by rising temperatures, making the human and mammalian survival impossible

With China on course to meet its 2030 climate goals with relative ease, it could now capitalise on its renewable energy advantages

Scientists have detected the gases carbon dioxide and hydrogen peroxide on Pluto's largest moon, 'Charon', which they said could help understand how icy bodies originated and evolved in the outer Solar System. Once considered the ninth and last planet of the Solar System, Pluto was demoted to a 'dwarf planet' status in 2006, when members of the International Astronomical Union voted to scientifically define a 'planet' for the first time. According to the resolution passed then, a dwarf planet is one that has not been able to create a clear orbit for itself, free from debris. Pluto's orbit, lying in the Kuiper belt region beyond the planet Neptune, was thought to cross with those of other objects. Charon is the largest of the five known moons of Pluto and has been studied since it was discovered in 1978. Being extremely cold, there's practically no chance for life to exist on Pluto and water, essential for life, is present as ice. The team, led by researchers at the Southwest Resear

About 12 per cent of Indian companies report emissions, exceeding the global average of 9 per cent, while 24 per cent of Indian firms set emission reduction targets compared to 16 per cent globally

Flight restrictions and precious metal refinery closures in early 2020 created worries that traders would not be able to move gold to the United States in time to deliver against futures contracts

Private steel major Tata Steel recently launched a carbon bank, a virtual repository through which carbon dioxide will become a value-creating asset for future usage, a company statement said here on Wednesday. CO2 is widely recognized as a harmful substance emitted due to the use of various fossil fuels in industry and transportation. The steel industry, in particular, often relies on coal and other fossil fuels in its production line, resulting in the release of large quantities of CO2. The carbon bank is aimed at measuring and managing carbon dioxide savings generated from various sustainability projects. These savings not only contribute to environmental goals but also hold the potential for generating revenue that can be reinvested into further decarbonization efforts, it said. Rajiv Mangal, Vice President (Safety, Health & Sustainability), Tata Steel, said "In the face of mounting global concerns about sustainability, Tata Steel has taken proactive steps to spearhead carbon .

The vacuum is projected to remove 36,000 tons of carbon annually, equivalent to eliminating emissions from approximately 7,800 gas-powered cars for a year

Under the terms of the agreement, SMBC has extended a long-term project finance facility to GreenCell Mobility for its 350 electric buses project in Uttar Pradesh, the company said in a statement

In 2019, India was among the top five economically developing countries in terms of carbon dioxide (CO2) emissions from aviation, a new research has found. Calculating "nearly real-time" aviation emissions using global flight data, researchers found that overall, the US, China and Great Britain were the topmost contributors, with 22 per cent, 14 per cent and roughly four per cent share. However, among the economically developing countries, India was found to be the third biggest contributor with close to three per cent share in global CO2 emissions from aviation, following China at 14 per cent and the United Arab Emirates (UAE) at more than three per cent. The research team at the Norwegian University of Science and Technology also found that India's share in global CO2 emissions from domestic aviation was the third highest at 1.5 per cent. "The countries with the highest absolute domestic aviation CO2 emissions (global percentage share in total CO2 aviation emissions in parenthese

The levels of the crucial heat-trapping gases in the atmosphere reached historic highs last year, growing at near-record fast paces, according to the US National Oceanic and Atmospheric Administration. Carbon dioxide, the most important and abundant of the greenhouse gases caused by humans, rose in 2023 by the third highest amount in 65 years of record keeping, NOAA announced Friday. Scientists are also worried about the rapid rise in atmospheric levels of methane, a shorter-lived but more potent heat-trapping gas. Both jumped 5.5 per cent over the past decade. The 2.8 parts per million increase in carbon dioxide airborne levels from January 2023 to December, wasn't as high as the jumps were in 2014 and 2015, but they were larger than every other year since 1959, when precise records started. Carbon dioxide's average level for 2023 was 419.3 parts per million, up 50 per cent from pre-industrial times. Last year's methane's jump of 11.1 parts per billion was lower than record annual

Bihar Chief Minister Nitish Kumar on Monday released a draft report that proposes strategies to reduce carbon emission in the state. The draft report on 'climate-resilient and low-carbon development pathway for Bihar' is in line with India's goal of achieving net-zero emissions by 2070. "The report provides a timely first-of-its-kind comprehensive analysis of future growth scenarios for Bihar to understand what a decarbonisation pathway entails and how it can spur economic growth, jobs and sustainability," state environment secretary Bandana Preyashi said at 'Bihar Climate Action Conclave' here. "The underlying principle driving the strategy is to embed climate action -- mitigation and adaptation -- into vision, programmes, policies, and budgets across sectors to lend credence to a net-zero and climate-resilient future," she added. According to the document, "development pathway focuses on choices and actions to reduce greenhouse gas emissions that contribute to climate change, and

Developing countries need more carbon space for economic growth, Union Minister R K Singh said on Friday as he emphasised that 77 per cent of the legacy carbon dioxide load has been caused directly by the developed countries. India aims to reduce its carbon emission intensity by 45 per cent by 2030. "Now, what is the present status on our planet? You have some countries that are developed and their average per capita income as per IMF figures is about USD 58,700 per year," Singh said at the World Sustainable Development Summit 2024 in the national capital. Singh, who is in charge of the power as well as new and renewable energy ministries, said there are developing countries where the average per capita income is USD 6,770 per year. "Just imagine the disparity. Now these developed countries (became) developed using fossil fuels and you know 77 per cent of the legacy carbon dioxide load on our planet earth was caused directly by them... that has led to this global rise in temperatur

The NCRTC is installing solar panels on rooftop spaces along the Delhi-Ghaziabad-Meerut RRTS, which is expected to yield 12.5 million units of solar energy and reduce 11,500 tonnes of carbon dioxide emissions annually, officials said on Saturday. A solar capacity of about three MW has already been installed over the platform sheds of RRTS stations at Sahibabad, Guldhar, Duhai, Duhai Depot station and Duhai workshop of the priority section, which will be able to meet the auxiliary load requirement of these locations, they said. "The National Capital Region Transport Corporation (NCRTC) is poised to install about 11 megawatt of solar capacity over its rooftop spaces along the 82 km-long Delhi-Ghaziabad-Meerut Regional Rapid Transit System (RRTS) corridor. This initiative is expected to yield 12.5 million units of solar energy annually and a reduction of 11,500 tonnes of CO2 emissions annually," an official said. Further solar power plants will be installed at the remaining stations of

Forty-one percent of the Indian population still uses wood, cow dung or other biomass as cooking fuel and cumulatively emits around 340 million tonnes of carbon dioxide into the environment every year, which is about 13 per cent of India's greenhouse gas emissions, according to a new report. The report "India's Transition to E-cooking" by the independent think tank Centre for Science and Environment also said that the Pradhan Mantri Ujjwala Yojana led to a rapid expansion in access to liquified petroleum gas (LPG) in India, but it has "not guaranteed a sustained transition to clean cooking in households" that benefited from the scheme. Around a third of the world's population 2.4 billion people globally (including 500 million people in India) still lack access to clean cooking solutions. This causes untold damage to the economy, public health and the environment. Approximately three million people globally (including 0.6 million people in India) die prematurely every year because

Union Agriculture Minister Arjun Munda on Monday launched a framework to promote the Voluntary Carbon Market (VCM) in the farm sector and said this will encourage small and medium farmers to avail benefits of carbon credit. Introducing farmers to the carbon market will not only benefit them but also accelerate the adoption of environment-friendly agricultural practices, the minister said. He launched the 'Framework for Voluntary Carbon Market in Agriculture Sector' and 'Accreditation Protocol of Agroforestry Nurseries' here, according to an official statement. He requested cooperation from the ministries concerned of the Centre and the states and other organisations to promote the carbon market in the interest of farmers. "Global challenges like global warming are in front of all of us; hence we have to move ahead with caution," the minister said. Munda said the Accreditation Protocol of Agroforestry Nurseries will strengthen the institutional arrangements for the production and .

India's per capita carbon dioxide emissions rose by around five per cent in 2022 to reach 2 tonnes but these were still less than half of the global average, according to a report released here on Tuesday. According to the Global Carbon Project, a group of international scientists, the United States topped the per capita emissions chart with every individual in the country emitting 14.9 tonnes of CO2 (carbon dioxide), followed by Russia (11.4), Japan (8.5), China (8), and the European Union (6.2). The global average stood at 4.7 tonnes. The US is also the biggest CO2 emitter since the Industrial Revolution. Over the entire period 18502022, the US' cumulative emissions amounted to 115 gigatonnes of carbon dioxide (Gt C) (24 per cent of the world total), the EU's to 80 Gt C (17 per cent) and China's to 70 Gt C (15 per cent). India has emitted 15 Gt C since 1850 which is just 3 per cent of the world's total. The data provided by the Global Carbon Project shows India's per capita ...

Extracting carbon dioxide from the atmosphere rather than sources of emissions, the direct-air method is the costliest application of carbon capture, according to the International Energy Agency

On a warming planet, plants like oaks and poplars will emit more of a compound that exacerbates poor air quality, contributing to problematic particulate matter and low-atmosphere ozone, a study shows. The same compound, called isoprene, can also improve the quality of clean air while making plants more resistant to stressors including insects and high temperatures. "Do we want plants to make more isoprene so they're more resilient, or do we want them making less so it's not making air pollution worse? What's the right balance?" said Tom Sharkey, a professor at Michigan State University in the US. "Those are really the fundamental questions driving this work. The more we understand, the more effectively we can answer them," Sharkey said. Isoprene from plants is the second-highest emitted hydrocarbon on Earth, only behind methane emissions from human activity. Yet most people have never heard of it, the researchers said. Isoprene interacts with nitrogen oxide compounds found in air
