A newer, more accurate method for calculating methane emissions from offshore oil and gas production suggests that the United Kingdom severely underestimates its greenhouse gas emissions. Researchers conclude that as much as five times more methane is being leaked from oil and gas production than reported.
While carbon dioxide (CO2) tends to be the most commonly discussed and recognized GHG, there are numerous other greenhouse gasses including methane, nitrous oxide, sulfur hexafluoride, and hydrofluorocarbons. The three major greenhouse gases are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Methane (CH4).
Just after the Big Bang, the universe was shrouded in a mist of hydrogen, and this oldest element is still all around us: in water (H 2 O), natural gas (with main component methane CH 4 ), and ammonia (NH 3 ). On its own, hydrogen hardly exists in nature: it is almost always bonded to something else.
The study found that hydrogen leaks, though impactful, are about three times less damaging to the climate than methane leaks (the primary component of natural gas) on a per-mass basis. When hydrogen leaks, it reduces atmospheric hydroxyl radicals (OH), which act as natural detergents by breaking down methane.
Other problematic sources of air pollution include methane, which produces hazardous ground-level ozone that is linked to health conditions such as lung damage, chest pain , and exacerbated respiratory diseases. Notably, both methane and many major forms of PM 2.5 Notably, both methane and many major forms of PM 2.5
Yet, it’s had the unintended consequence of ramping up near-term globalwarming. But given that sulfur also cools the planet, failing to rein in, at the very least, short-lived greenhouse gases like methane while reducing sulfur pollution simply ratchets up the rate at which the world warms.
You’ll understand what products and processes emit g reenhouse gases (GHGs), including the carbon-containing gases carbon dioxide and methane. Carbon dioxide equivalent” is a standard unit for counting greenhouse gas (GHG) emissions regardless of whether they’re from carbon dioxide or another gas, such as methane.
These indicators, including but not limited to carbon dioxide, methane, ocean acidification, tropical forest loss, population, GDP, water use, and transportation, have reached the point past natural variation, showing indisputably that the Earth is in a different state than before. .
Diverse compounds are emitted by everything from motor vehicles to power plants, and include both greenhouse gases and short-lived climate pollutants – which are known to fuel globalwarming – as well as a host of volatile organic compounds that can lead to short- and long-term health problems in humans.

Methane emissions reduction could significantly reduce rates of globalwarming at a relatively low cost, major research warns. As such, the report emphasises that methane mitigation is "one of the best ways of limiting warming in this and subsequent decades".
However, industry has yet to provide the kind of comprehensive data needed to estimate how far any possible climate benefits from switching to blue hydrogen produced by the planned projects may offset the residual CO2 emissions and methane leaks associated with making it. percent — less than the estimated global average of 1.4
” “Globalwarming could challenge the very fabric of the world’s ecological and economic systems,” Shell executive Ged Davis wrote in a contribution to a report by the Organisation for Economic Co-operation and Development (OECD) published two years later. .”
Just 50 nations worldwide now outside initiative that aims to cut methane emissions 30 per cent by 2030. First launched with just over 100 national backers at the UN Climate Summit in Glasgow a year ago, the GlobalMethane Pledge commits signatories to collectively reducing emissions of the gas by 30 per cent between 2020 and 2030.
Although this level was not defined by the convention, the aim was to allow ecosystems and society to adapt naturally to climate change, which means slowing globalwarming down. In addition, several states have their own more demanding legislation in place, such as California’s and Massachusetts’ GlobalWarming Solutions Act.

All the top green business news from around the world this week, including fresh WHO air pollution guidelines and global coal, methane and HFC commitments. More countries join globalmethane and coal power pledges. President Biden unveils plan to slash climate-warming HFCs.
Preliminary data shows that methane emissions jumped in 2020 by the largest amount since systematic record-keeping began decades ago. The National Oceanic and Atmospheric Administration (NOAA) said that globalmethane concentrations shot up by 14.67 Globally averaged, monthly mean atmospheric methane abundance.
