In this article, we present a comparative analysis of the carbon emissions associated with AI systems (ChatGPT, BLOOM, DALL-E2, Midjourney) and human individuals performing equivalent writing and illustrating tasks. Our findings reveal that AI systems emit between 130 and 1500 times less CO2e ...
To make calculations more manageable, we normalize all GHG numbers to carbon dioxide equivalent (CO₂eq). For example, one ton of methane has the same warming effect as about 25 tons of CO₂, so we normalize it to 25 tons CO₂eq. We might shorten it to just carbon, which often ...
Breeding of rice varieties with low carbon dioxide equivalent (CO2e) emission is essential in reducing global greenhouse gas (GHG) emissions. In this study, we compared the gross CO2e emission of two newly developed green super rice (GSR) varieties with elite hybrids and nationally released farme...
5.3 Carbon emissions Contrary to most western countries, where the question of carbon emissions reduction is raised in almost any debate about future energy supply schemes, this issue has so far been widely neglected in the approaches to electricity planning of the MENA countries. The scientific lit...
CO2 emission in the transport sector has attracted significant attention from policymakers in both transport and climate change fields because of its share in the overall emissions and continuous growth [2]. According to the International Energy Agency [3], 6.57 billion tons of global CO2 was ...
Also called direct emissions, Scope 1 emissions are released directly from sources that are owned or controlled by an organization. Examples include emissions produced from manufacturing processes, fugitive emissions like methane emissions from coal mining or the onsite production of electricity by burning...
emissions: 3000 kWh per year electricity usage * 0.58982 kg carbon dioxide equivalent (CO2e) per kWh = 1,769 kgCO2e 1.781 tCO2e 7500 kWh per year gas usage x 0.22674 kg carbon dioxide equivalent (CO2e) per kWh / 1000 = 1,701 kgCO2e 1.701 tCO2e 1000 kg Waste per Year * ...
carbon emissions9,10. The net amount of carbon captured by plants through photosynthesis over a given period is called net primary production (NPP)11,12. NPP is closely related to a carbon sink, which is equivalent to NPP minus the component of soil heterotrophic respiration13; thus, NPP ...
equivalent to an area double the size of Singapore (719 km2), with a loss rate of 0.28% year−1from 2000 to 2019. Net global losses resulted in 16.3 (0.4–33.2, 90% confidence interval) Tg CO2e year−1emissions from 2000 to 2019 and a 0.045 (−0.14–0.115)...
Significant emissions are also released from the lagoons used to store untreated farm and animal waste. When put together, the carbon equivalent emissions from livestock are greater than the emissions from all passenger vehicles in the world. Additionally, the manure lagoons at many animal processing...
