The globally averaged surface concentration of carbon dioxide reached 420 parts per million (ppm), methane 1934 parts per billion and nitrous oxide 336.9 parts per billion (ppb) in 2023.

A new UN report highlights the urgent need to address nitrous oxide emissions, which are accelerating climate change, harming the ozone layer, and posing serious health risks.

More than half of clinical trial participants treated with venetoclax, ibrutinib, prednisone, obinutuzumab, and lenalidomide (ViPOR) had substantial tumor shrinkage. Of those, 38% had tumors that disappeared completely.

Gurgaon-based startup OnlyGood FutureTech helps companies measure emissions generated by supply partners

The study by Delhi-based independent think tank Council on Energy, Environment and Water (CEEW) said policies for India's power, residential and transport sectors have already saved 440 million tonnes of carbon dioxide (MtCO2) between 2015 and 2020.

In 2023, the largest absolute contributions to global fossil CO2 (carbon dioxide) emissions were from China (31%), followed by the United States with 13% and India taking up 8%

More than 100 world leaders converged upon New York City today to discuss international efforts to reduce carbon emissions and combat climate change. The list of speakers at the UN Climate Summit included U.S. President Barack Obama, UK Prime Minister David Cameron, Brazilian President Dilma Rousseff, French President François Hollande, and Chinese Vice Premier Zhang Gaoli.

California and Quebec, which together created the largest carbon market in North America this year, may come away empty-handed as they woo northeastern U.S. states to join their system.

Global emissions were unchanged last year, the first time that’s happened amid economic growth in four decades, according to the International Energy Agency.

President Barack Obama ordered the federal government to reduce greenhouse gas emissions by 40 percent from 2008 levels over the next 10 years by shifting to renewable energy sources such as solar power.

Mexico has become the first developing nation to formally promise to cut its global-warming pollution, a potential milestone in efforts to reach a worldwide agreement on tackling climate change.

What do the following have in common: New Zealand, South Korea, Switzerland, Kazakhstan, Quebec, Alberta, Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, Vermont, California, Beijing, Guangdong, Hubei, Shanghai, Shenzhen, Chongqing, Tianjin, Tokyo, Kyoto, Saitama and 28 countries in Europe?

Carbon emissions in 2014 remained at the previous year’s levels of 32.3 billion metric tons — a milestone that points to the impact worldwide renewable energy investment is having in the face of a 1.5 percent annual increase in global energy consumption, according to a new report from REN21. The tenth annual Renewables 2015 Global Status Report cites “increased penetration of renewable energy” and improvements in energy efficiency as the chief reasons for the noted emissions stabilization.

European Union leaders intend next month to agree on a timeline for developing energy and climate targets for 2030, delaying a final decision on the polices, according to two people with knowledge of the matter.

Japan said the U.S.’s proposed cuts in greenhouse-gas emissions from its power plants is a bold step to tackle climate change.

We must aim for their complete elimination by the second half of the century and need to come to grips with the risk of climate change. While many countries have announced ambitious targets to reduce fossil fuel emissions by 2020, and even mid-century, further efforts are needed.

Governments need to put together the optimal policy mix to eliminate emissions from fossil fuels in the second half of the century. Cherry-picking a few easy measures will not do the trick. There has to be progress on every front, notably with respect to carbon pricing, and that is what peer review and learning from best practice should help achieve, said OECD Secretary-General.

Carbon taxes and emission trading systems are the most cost-effective means of reducing CO2 emissions, and should be at the centre of government efforts to tackle climate change,according to a new OECD study.

Taxes are potentially among the most effective ways of cutting pollution and greenhouse gas emissions, but they are currently – with very few exceptions – underused; and even where used, they are frequently designed in a sub-optimal way.

More than 150 countries have submitted their post-2020 Intended Nationally Determined Contributions (INDCs) to the United Nations Framework Convention on Climate Change (UNFCCC). Such contributions are vital to the #COP21 climate change conference in Paris this December.

Advanced and emerging economies have made progress in addressing climate change, yet most are on a trajectory that would see them fall short of their mitigation goals. Governments need to significantly accelerate their efforts and strengthen their climate change policies.

A stern warning for climate change, and our health - Shipping brings us 90% of world trade and has increased in size by 400% in the last 45 years. Cargo ships, tankers and dry-bulk tankers are an essential element of a globalised world economy, but they are thirsty titans and they won’t settle for diet drinks. There are up to 100,000 working vessels on the ocean and some travel an incredible 2/3 of the distance to the moon in one year.

This summer, we witnessed record-breaking heat and extreme weather events across the globe. To address the urgent climate challenge, and meet our broader development goals, trillions of dollars need to be invested in low-emissions and resilient infrastructure.

Emissions curbs set by the European Union’s Emissions Trading System, Europe’s main tool for reducing carbon emissions, have not hurt revenue, profits or employment at firms subject to the cap-and-trade programme over 2005-2014, according to a new OECD report.

Australia has made some progress replacing coal with natural gas and renewables in electricity generation yet remains one of the most carbon-intensive OECD countries and one of the few where greenhouse gas emissions (excluding land use and forestry) have risen in the past decade. The country will fall short of its 2030 emissions target without a major effort to move to a low-carbon model, according to a new OECD report.

Turkey will see its greenhouse gas emissions continue their steady rise of recent years without concrete actions to improve energy efficiency and increase the use of renewable energy sources, according to a new OECD report.

OECD Secretary-General, Mr. Angel Gurría, gives his views in this blog from the World Economic Forum in Davos on the huge risk that carbon dioxide emissions pose to the economy and the environment.
