Seagrass had the highest annual methane air-sea fluxes but the lowest global warming potential in carbon dioxide equivalent due to a decrease in its flux. Hence, seagrasses can help climate change mitigation compared to bare sediments.#Tropical seagrasses and adjacent unvegetated mudflats both emit ...

on a 30-year timeline, our analysis shows that more than 90 percent of the potential emissions reductions associated with these solutions could be achieved at a cost of less than $25 per ton of carbon-dioxide equivalent (tCO2e)—a price sometimes paid in th...
GWP values calculated over a time horizon of 100 years (denoted GWP100) have been employed particularly extensively in climate studies to report emissions of various GHGs on the same scale as CO2(ref.2). GWP100values are used to estimate cumulative CO2-equivalent emissions of an LLCF over a ...
According to a new study published this week in the journal Science, lengthy blow-ups on pipelines and at wellheads—as happened in the Belmont county explosion—are behind the release of roughly 8m tonnes of methane every year. That is equivalent to between 8% and 12% of the estimated tot...
These studies have shown that methane emissions from many sources could be reduced substantially, often using known technology or by transfer of good practice. Opportunities to reduce methane emissions may be relatively inexpensive compared with equivalent reductions in emissions of other greenhouse gases....

We clearly demonstrated that in our systems, diffusive CH4 flux (in terms of CO2 equivalent) were of minor importance in the GHG emissions (without CH4 accumulation under ice), with diffusive CO2 flux generally accounting for more than 95% of the annual diffusive flux. We also noted the ...

6 Results: “carbon majors” A total of 914 billion tonnes of CO2-equivalent (GtCO2e) has been traced to 90 international entities based on analysis of historic production records dating from 1854 to 2010. These entities cumulatively produced 985 billion barrels (bbl) of crude oil and NGLs (...
