To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climatechange, according to a new report from the National Academies of Sciences, Engineering, and Medicine.
Recent reports in the scientific literature and popular press have produced confusion about the climate implications of natural gas. On the one hand, a shift to natural gas is promoted as climate mitigation because it has lower carbon per unit energy than coal or oil. This would eventually be offset by a modest benefit.
People from Chevron and Toyota will be driving Toyota’s Tundra, RAV4 and Camry on this road trip with the objective of demonstrating the fuel, which is more than 40% less carbon intensive than traditional gasoline on a lifecycle basis, according to Chevron. United States. doi: 10.2172/1846005
The Alternative and Renewable Fuels and Vehicle Technology Program’s Investment Plan allocates $176 million over the next two years to stimulate green transportation projects and encourage innovation to help meet the state’s aggressive climatechange policies.

A new working paper published by the International Energy Agency (IEA) concludes that natural gas can play a significant role in cutting on-road vehicle carbon dioxide emissions, but that over the long term there will need to be a commitment to transition to very low CO 2.

You’ll be helping to cut your carbon footprint and you’ll be doing the South Bay community a good turn. Maybe you missed their headline yesterday that read: Scientists: Pace of ClimateChange Exceeds Estimates. I advise the other dead-ender subscribers still left to cancel and read for free too.
An 80% reduction in US greenhouse gas (GHG) emissions by 2050 has been generally established as the de facto required domestic contribution to stabilizing global concentrations at low to medium levels, that is, 450 and 550 ppm carbon dioxide equivalent (CO 2 -equiv).
Although many of these technologies are availabletoday, the emissions reductions and fuel economy improvements proposed would involve more widespread use of these technologies across the light-duty vehicle fleet. Tags: ClimateChange Emissions Fuel Efficiency Policy. Preliminary regulatory impact analysis.
Climate pledges by governments to date—even if fully achieved—would fall well short of what is required to bring global energy-related carbon dioxide emissions to net zero by 2050 and give the world an even chance of limiting the global temperature rise to 1.5 °C,
Tackling road transport energy use is vital to enhancing energy security and reducing carbon dioxide emissions globally. Even though most of the key fuel economy technologies are availabletoday, additional breakthroughs and cost reductions would help, including lighter materials, advanced combustion systems and better lubricants.
Around $176million will be invested over the next two years as the California Energy Commission adopts the Alternative and Renewable Fuels and Vehicle Technology Program’s Investment Plan to encourage innovation and meet the state’s climatechange policies.
The two companies believe this strategy will work, citing research carried out for the French carmaker which indicates that 80% of people in Europe currently travel less than 60km per day; well within the range of many electric vehicles availabletoday.
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. But use of petroleum will continue.
