The benefit to the climate of using biofuels as a substitute for fossil fuels has been sharply contested for years; much of the disagreement is based on the assumptions underlying the carbon accounting in the lifecycle analysis. Assuming that biogenic carbon flows are always in balance over a biomass product’s lifecycle—i.e.,
A new statistical method developed by researchers at KAUST (King Abdullah University of Science and Technology, Saudi Arabia) can detect abnormal ozone levels within large bodies of monitored data. The monitoring methods can quickly and accurately detect ozone anomalies—localized spikes in ozone concentration indicated by sensor data.
Carbon emissions associated with increased exports from China (left), as part of a more systematic view of increased national emissions (right), 2002 to 2005. Researchers from Norway, the United Kingdom, and the United States, estimated in the study that China’s 2005 carbon emissions were 80.59% or more higher than 2002 emissions. “

The country’s 2008 GDP growth rate has been revised upward from 9.0
Carbon dioxide emissions from these rigs would be able to be significantly reduced if these faults were rectified by as much as 15%, according to a large-scale test that tyre manufacturer Michelin carried out in partnership with Volvo Trucks. Two-thirds of Europe’s truck rigs are driving around with incorrect wheel alignment.
It also showed that global annual emissions of greenhouse gases increased from 24 billion tonnes of carbon dioxide equivalents in 1970 to 33 billion tonnes in 1990 and 41 billion tonnes in 2005. EDGAR used the latest international statistics and data on greenhouse gas emissions to model emissions for every country in the world.
The growth of global industrialization, increasing demand on energy resources and rising carbon emissions are deepening the need for energy infrastructure that is increasingly green, distributed, flexible, and resilient. Grid balancing and resilience is not a challenge borne out of our transition to a net-zero carbon economy.

The report also considers the efficiency (and inefficiencies) in the current system, as well as considering the aggressive investments that other trade blocs are making in new infrastructure and lower-carbon transportation—investments that may be outpacing efforts in North America. Shifting to lower-carbon fuels. Training Eco-drivers.
The end-Permian extinction is associated with a mysterious disruption to Earth’s carbon cycle. First, we show that geochemical signals indicate superexponential growth of the marine inorganic carbon reservoir, coincident with the extinction and consistent with the expansion of a new microbial metabolic pathway.
