CO2 Emissions

The Centre has amended motor vehicle rules to permit vehicles running on 100 per cent ethanol, clarifying that existing vehicles need not switch fuels or undergo modifications.

UNEP says India is likely to meet its climate targets under current policies. However, global emissions must fall much faster to limit peak warming and return to 1.5°C by the end of the century

The government has proposed BS-VII emission norms from April 2029, introducing stricter real-world testing and brake and tyre pollution limits, while automakers seek more time to comply

The panel has proposed mandatory filtration of PM2.5 and VOCs inside vehicle cabins, remote sensing of emissions, and incentives for EV adoption and retrofits

Final CAFE-3 rules drop the special 909-kg concession but soften targets for lighter cars through a revised formula, while tightening norms for heavier vehicles

An Energy Institute report found that higher natural gas prices prompted US power producers to increase coal use, driving a significant share of global emissions growth

Analysts say clean energy growth in Asia offset increased coal-fired generation in the US, limiting overall emissions growth in 2025

While India's CAFE formula resembles the European Union, it lacks any adjustments for protecting small cars

NTPC Ltd on Saturday said it has started drilling for the country's first-ever CO2 injection borewell at its Pakri Barwadih coal mine in Jharkhand. This move, led by the company's R&D arm, NETRA (NTPC Energy Technology Research Alliance), is a decisive step towards fulfilling India's Carbon Capture, Utilization and Storage (CCUS) roadmap and its net-zero commitment by 2070, NTPC said in a statement. "NTPC has marked an important milestone in the nation's clean energy transition by commencing drilling for the country's first-ever CO2 Injection Borewell at its Pakri Barwadih Coal Mine, Jharkhand," it said. The CO2 borewell is being drilled to an approximate depth of 1,200 metres. Its primary purpose is to secure crucial geological and reservoir data required for establishing a safe and effective CO2 storage process. This includes extensive core, methane, and water sampling, alongside seismic monitoring and detailed simulation studies to assess the rock formations' ability to ...

As COP30 opens in Brazil, record CO₂ levels and faltering global leadership leave climate goals in peril, testing the world's resolve to act on its promises

The UN weather agency said Wednesday that carbon dioxide levels in the atmosphere hit new record highs last year, and heat trapped by such greenhouse gases is turbo-charging the Earth's climate and causing more extreme weather. The World Meteorological Organisation said in its latest bulletin on greenhouse gases that C02 growth rates have now tripled since the 1960s, and emissions from human activities and more wildfires helped fan a vicious climate cycle." The Geneva-based agency said the increase of the global average concentration of carbon dioxide from 2023 to 2024 amounted to the highest annual level of any one-year span since measurements began in 1957. The heat trapped by CO2 and other greenhouse gases is turbo-charging our climate and leading to more extreme weather," said WMO Deputy Secretary-General Ko Barrett in a statement. "Reducing emissions is therefore essential not just for our climate but also for our economic security and community well-being, The increase in 202

The world's largest maritime nations are gathering in London on Tuesday to consider adopting regulations that would move the shipping industry away from fossil fuels to slash emissions. If the deal is adopted, this will be the first time a global fee is imposed on planet-warming greenhouse gas emissions. Most ships today run on heavy fuel oil that releases carbon dioxide and other pollutants as it's burned. Nations are meeting at the International Maritime Organization headquarters through Friday. The Trump administration unequivocally rejects the proposal and has threatened to retaliate if nations support it, setting the stage for a fight over the climate deal. In April, IMO member states agreed on the contents of the regulatory framework. The aim is to adopt it at this meeting. That would be a major win for the climate, public health, the ocean and marine life, said Delaine McCullough at the Ocean Conservancy. For too long, ships have run on crude, dirty oil, she said. This ...

Regulators have threatened fines and the closing of one of the plant's coke facilities if Tata Steel fails to significantly reduce toxic emissions this year

The changes to India's policy on emissions from coal plants are not a rollback - but a confident assertion of regulatory maturity, scientific integrity, and rational national interest

Industry divide complicates govt's efforts to finalise new fuel-efficiency norms

If the world continues to release carbon dioxide at the current rate, the carbon budget for limiting global warming to 1.5 degrees Celsius will be exhausted in just over three years, according to an international group of scientists. The carbon budget refers to the total amount of carbon dioxide the planet can emit while still having a good chance of staying below a certain temperature threshold. In this case, the limit is 1.5 degrees Celsius, which countries agreed to at the Paris climate conference in 2015. Exceeding the carbon budget does not mean the 1.5-degree limit will be crossed immediately. It means the world is on course to surpass it very soon unless emissions are drastically cut. The latest "Indicators of Global Climate Change" study, published in the journal Earth System Science Data, also found that the carbon budget for 2 degrees Celsius could be exceeded by 2048 if current levels of CO2 emissions continue. Scientists said human activities have led to the release of

Delta Electronics would source a combined 9.6 million units of wind power annually to power its manufacturing facilities in Tamil Nadu

Thus far, upward of 13.5 million metric tonnes-worth of carbon dioxide removal (CDR) credits have been bought, and just 4.7 per cent of those have been delivered

How should we make sense of this situation? What is the path ahead? Are we headed for a runaway climate change dystopia or can we do better?
