Why EVs Aren't a Climate Change Panacea

Cars That Think

Environmental groups foresee the public needing to use electrified mass transit , reduce long-haul flights for business as well as pleasure), increase telework, walk and cycle to work or stores, change their diet to eat more vegetables, or if absolutely needed, drive only small EVs. The answer is perhaps some, but maybe not too much.

UOP/Solazyme Neat Renewable Diesel from Algae Oil Powers Vehicle at United Nations Climate Change Conference

Green Car Congress

One of those vehicles is a Mercedes-Benz E-Class powered by unblended renewable diesel produced by UOP’s Ecofining process ( earlier post ), using oil from algae provided by Solazyme. Green diesel offers value as a blending stock for refiners seeking to enhance existing diesel fuels and expand the diesel pool.

All-in-one solar-powered tower makes carbon-neutral kerosene in the field at pilot-scale

Green Car Congress

The aviation sector is responsible for about 5% of global anthropogenic emissions causing climate change. It relies heavily on kerosene (jet fuel)—a liquid hydrocarbon fuel typically derived from crude oil. (A)

KIST team develops technology for mass-production of lignin-bio-aviation fuels

Green Car Congress

The ability to produce aviation-grade fuel from oil derived from wood waste—which up until now has been difficult due to the high viscosity of the oil—could help international aviation companies comply with new emissions regulations scheduled to go into effect in 2027. Lignin constitutes 20 to 40 percent of lignocellulose.

Flaring practices allow more methane into the atmosphere than thought; simple fixes can have big impact

Green Car Congress

Oil and gas producers rely on flaring to limit the venting of natural gas from their facilities. Methane—which can be a byproduct of oil production—is a powerful greenhouse gas. Flights were conducted in the Permian and Eagle Ford oil and gas fields in Texas, as well as the Bakken oil and gas field in North Dakota.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

Based on visual interpretation of high-resolution (30 m) satellite images, a new study in the journal Global Change Biology: Bioenergy determined that industrial plantations covered over 3.1 Slightly more than half of the GHG emissions for these biofuels in the EPA’s analysis came from land use change. Earlier post.).

Researchers show oil palm plantation expansion a significant source of CO2; projected to contribute more than all of Canada’s current fossil fuel emissions by 2020

Green Car Congress

Oil palm supplies more than 30% of world vegetable oil production. The study, published as an open access paper in the journal Nature Climate Change , shows that deforestation for the development of oil palm plantations in Indonesian Borneo is becoming a globally significant source of carbon dioxide emissions.
