California 2017 GHG inventory shows 1.2% total drop from 2016; transportation sector emissions up 1%

Green Car Congress

Transportation sector emission sources include combustion of fuels utilized in-state that are used by on-road and off-road vehicles, aviation, rail, and water-borne vehicles, as well as a few other smaller sources. In-State Hydro, Solar, and Wind Electricity Generation. This is, however, the lowest growth rate over the past 4 years.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet.

Study: Urban grime releases NOx when exposed to sunlight

Green Car Congress

When in the air, these compounds may combine with volatile organic compounds to produce ozone, the main component of smog. In a subsequent laboratory comparison, they found that nitrate disappeared from grime 10,000 times faster than from a water-based solution when both were exposed to artificial sunlight. —James Donaldson.

UC Davis Begins $2.8M Studies on Impacts of Escaped Nitrogen

Green Car Congress

But excess nitrogen is emitted from soils, seeps into groundwater and runs off into surface waters. Nitrogen runoff in bays and coastal areas, where it makes algae numbers spike then crash, drawing oxygen from the water and leading to dead zones—areas that cannot support finfish, shellfish or most other aquatic life.

Earth Day and the Importance of Green Energy

Blink Charging

According to Forbes , studies have found that solar and wind power is often cheaper than power from fossil fuels, even without financial assistance, and their daily operations undercut even the most cost-effective coal plants. Solar energy is harnessed using photovoltaic cells that capture sunlight and turn it into electricity.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Soot—black and brown particles that absorb solar radiation—comes from two types of sources: fossil fuels such as diesel, coal, gasoline, jet fuel; and solid biofuels such as wood, manure, dung, and other solid biomass used for home heating and cooking around the world. Dessler et al., 2008] and methane [Schutz et al., Guenther et al.,
