Hatched areas indicate locations in which the difference is statistically significant at a 95% confidence level. and d contrail cirrus net radiative forcing due to a 80% reduced initial ice crystal number (low minus present-day initial ice crystal number). Burkhardt et al.
The first real-world, head-to-head comparison of improved cookstoves (ICs) and traditional mud stoves has found that some ICs may at times emit more of the black carbon particles that are linked to serious health and environmental concerns than traditional mud stoves or open-cook fires. —Kar et al.
Despite the economic effects of the global financial crisis (GFC), carbon dioxide emissions from human activities rose 2% in 2008 to an all-time high of 1.3 tonnes of carbon per capita per year, according to a new paper published by an international team of 31 scientists in Nature Geoscience. Global carbon budget 2008.
Replacing a gasoline-powered ride-hailing vehicle with an electric vehicle can deliver three times the carbon benefits of a personally owned electric vehicle, according to a study by a University of California, Davis, researcher of Uber and Lyft data. The paper is published in the journal Nature Energy. —Alan Jenn.
But unless they're charged entirely on renewable energy—still statistically unlikely today—there are emissions associated with generating the electricity used to charge their batteries. For several years now, rigorous "wells-to-wheels" analyses of the carbon-dioxide emissions.
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.
Senate Bill 32, signed in 2016, requires the state to go even further than AB 32 and cut greenhouse gas emissions 40% below 1990 levels by 2030—the most ambitious carbon goal in North America. The carbon intensity of California’s economy has dropped 38% since the 2001 peak and is now one-half the national average.
The findings, published in the 21 September issue of Atmospheric Chemistry and Physics , are generally consistent with official Chinese government statistics and could bolster their credibility as international negotiations proceed on commitments of China and other nations to combat climate change.
The study, published recently in Atmospheric Environment , investigated commuter exposure to PM 2.5 , black carbon (BC), and ultrafine particles (UFP) in six common transport microenvironments in Sacramento, California. One important finding is the need for more light rail and dedicated bike paths, as well as cleaner locomotives.
The overall carbon emissions associated with electric cars decrease as the electricity used to recharge them gets cleaner. And the latest statistics from the International Energy Agency (IEA) will be good news indeed for electric-car drivers.
Achieving these goals will require the transportation sector to compress its product development cycle for cleaner, more efficient engine technologies by 50% while simultaneously exploring innovative design space. Achievable advances in engine technology can improve the fuel economy of automobiles by over 50% and trucks by over 30%.
Researchers at Caltech and JPL used statistical mechanics to design a polymeric fuel additive that can self-assemble into “megasupramolecules” (≥5000 kg/mol) at low concentration (≤0.3 weight percent) and thus can reduce the intensity of post-impact fuel explosions that occur during accidents and terrorist acts. Ming-Hsin Wei, Boyu Li, R.
This statistic alone puts the growth of electrification into stark contrast and demonstrates our monumental national progress towards a cleaner, greener, lower carbon car parc.
UK’s Progress Toward Zero Emissions: A Roadmap to a Sustainable Future The United Kingdom is making significant strides toward achieving a zero-emissions future, aligning with its ambitious goal to become carbon neutral by 2050. This represents a 21.4% increase from 2023 and accounts for 19.6% of all new car sales. thetimes.co.uk
When you ask people about cleaner energy, they think of electricity,” says Tommi Eronen, CEO of Polar Night Energy. We need to protect and restore forests so they can keep removing carbon from the air. Statistics Finland , “Over one-half of Finland’s electricity was produced with renewable energy sources in 2020”, November 2021.
However, some issues remain, such as providing adequate charging infrastructure or ending reliance on fossil fuels to generate power and minimize carbon emissions. The statistics can differ depending on how much sunlight each location receives each year. ” Dima Steesy.
Appendix D: Vehicle Driving Statistics. The combination of harvesting whole forests and burning long-sequestered carbon sources such as coal or oil has impaired the Earth’s carbon cycle at an increasing pace. To restore balance we must protect the oxygen-producing biomass of Earth and reduce the amount of carbon emissions.
In Germany, statistics from the Federal Motor Transport Authority reveal that total car registrations in March fell by 38% while fully electric cars actually grew by 56% and hybrids by 208%. In fact, just a few days ago Germany and France announced a €500 billion green recovery fund to accelerate the EU’s shift to a low-carbon economy.

As environmental concerns continue to rise, brands and consumers alike are looking to do their part to reduce their carbon footprint.
2025 Chevrolet Equinox EV “As a result of the regulatory costs, distortions, and pressures imposed by the existing CAFE standards, more Americans will be relegated to driving older and older used vehicles, which statistics show are much less safe in a highway crash,” the new Transportation Secretary wrote.
