Seagrass ecosystems are important carbon dioxide sinks that can sequester carbon for centuries as organic matter in sediment. They are also a major source of methane, a potent greenhouse gas, which limits their carbon sink capacity. However, data are lacking on their methane emission dynamics. Here...
Carbon dioxide emissionsMethane emissionsGreenhouse gas emissions associated with Representative Concentration Pathway RCP2.6 could limit global warming to around or below a 2 掳C increase since pre-industrial times. However this scenario implies very large and rapid reductions in both carbon dioxide (CO2...
Limiting the rise in global mean temperatures relies on reducing carbon dioxide (CO2) emissions and on the removal of CO2 by land carbon sinks. China is currently the single largest emitter of CO2, responsible for approximately 27 per cent (2.67 petagrams of carbon per year) of global fossil...
methane needs to be regenerated after a period of reaction to restore the reducing equivalent in the cell. Xin et al.[171]also found that IMV3011 can catalyze the bioconversion of CO2to methanol. However, the ability to synthesize methanol is limited by the reduction equivalent in the cell. ...
Reaching this target would clearly be easier if the use of oil and gas declined. But even if demand doesn’t fall much, the sector can abate the majority of its emissions, at an average cost of less than $50 per ton of carbon-dioxide equivalent (tCO2e), by priorit...
Its greenhouse gas emissions over the same period would also increase by only 40%, to 2,990 million tonnes of carbon dioxide equivalent (Mt CO2e), leaving the country's overall emissions close to its benchmark 1990 emissions level. This anticipated development has been forecast as the "...
1 litre of GPL produce 1.56 kg of CO2.(3000.0*0.52=1560.0) Methane CNG (compressed natural gas):CH4+ 2 O2--> CO2+ 2 H2O + energy 1 mol CH4(16 g/mol) --> 1 mol CO2(44 g/mol) => 16g --> 44g => 1000/16*44=2750g ...
The OGCI, a group of leading energy companies, recently introduced new measures to address climate challenges at its fifth annual conference and said it was making progress curbing methane emissions.
Carbon dioxide equivalent or "CO2e" means an amount of greenhouse gas or gases expressed as the equivalent amount of carbon dioxide, and is computed by multiplying the mass of each of the greenhouse gases by the global warming potential published for each gas at 40 CFR part 98, subpart A,...
Electroreduction of carbon dioxide (CO2) is a potential strategy to transform the intermittent sources of energy into high-energy chemicals, which can potentially reduce our dependence on fossil fuels and alleviate atmospheric pollution1,2,3,4. Among the products formed upon electrochemical CO2 reductio...
