Hydrogen Fuel’s Potential to Decarbonize Aviation

Air travel accounts for about 2.5 percent of global carbon emissions. To reduce emissions from aviation, ZeroAvia is seeking to build the world’s first zero-emission passenger jet powered by hydrogen fuel, which offers three times more energy per kilogram than jet fuel and emits no toxic fumes when combusted. Hydrogen fuel’s higher energy density and capacity for consistent electrical power make it a promising potential energy source for aircraft.

Electrifying Motorcycle Taxis in Africa to Reduce Emissions and Save Drivers Money

Electric motorcycles and battery swap technology can improve livelihoods and reduce emissions in Africa and around the world. Ampersand, an African electric vehicle company, provides affordable electric motorcycles (called “e-motos”) in East Africa and operates a convenient battery swap system. These e-motos are replacing polluting gas motorcycles with a cost-effective and environmentally friendly alternative.

Electric Vehicle Retrofitting with Dr. Aly El Tayeb


To decarbonize transportation, we’ll need to switch to electric cars. New electric vehicles are decreasing in price and increasing in range and accessibility, but remain out of reach for many. Could EV Retrofitting, a process that converts cars from internal combustion to electric in just a few hours, be what fills in the gap? Listen to Climate Break talk to Dr. Aly El Tayeb, founder of Egyptian retrofitting startup EV Shift, about its potential.

Why Smart Land Use Can Reduce the Need to Drive with Dr. Steve Cliff


Before California can reduce its vehicle miles traveled (VMT) — which measures total amount of driving occurring in the state — we need to start thinking differently about how we use space. Hear from Dr. Steve Cliff, Executive Officer of the California Air and Resource Board (CARB), on how he’s thinking about the role for land use and planning in decarbonizing transportation and reducing VMT.
