Carbon Flying: It's a Drag We’re stuck with airliners powered by fossil fuels for now, but we can significantly cut emissions with innovations that reduce aerodynamic drag.
Hope Renewables Growth Will Limit Warming – AI Modelling AI model predicts greater levels of wind and solar PV renewables in the global supply by 2050, sooner than current policies would predict, enough to limit global warming to 2 degrees.
Hope Reducing Carbon Dioxide Emissions from Shipping by Half A ship-borne system employing accelerated weathering of limestone to capture carbon dioxide from exhaust gas is better and cheaper than land-based systems.
Hope How Policy Is Like the Tide Policy might seem slow and boring, but sometimes it's the most effective action. Solar PV for parking lots is a good example.
Hope Gyrotron Well Drilling for Deep Geothermal Energy Bit-less deep-well drilling teases the prospect of terawatts of clean energy.
Hope Sail-Powered Cargo Ships Scale Up A new, much-bigger addition to the world's fleet of hybrid sail/diesel-powered commercial cargo ships.
Hope EVs Deliver Lowest Lifecycle Carbon Footprint Everywhere Cradle-to-grave GHG emissions of light duty electric vehicles are lower than all forms of their internal combustion-engined equivalents, no matter the region
Materials Cooler Cement Changing the surface microstructure of cement reduces concrete's contribution to global warming by keeping structures cooler
Hope One New Way of Making Low-carbon Cement Even cement production can be electrified, for a 90% reduction in GHGs
Hope Climate for the win! The Vermont Greens FC won their 2025 national championship. Why it matters for climate change.
Electricity Kilowatt Batteries. OMG! Sophisticated and useful energy-dense "personal power stations" have quietly come to market. They are impressive.
Hope Teach your children well If we have hope, it will be realized from the impact of coming generations.
Hope Tidal Turbine Bearings and Seals Critical components for successful long-term tidal turbine operation reach a major reliability milestone.
Wind Bladeless Wind Generators A Spanish company is developing wind generators that exploit the vortex-shedding effect. The tapered towers have no rotating parts.
water More Fish in the Sea Marine preservation areas work well when properly managed. That's great ... because we need them.
Hope Reusable Hospital Isolation Gowns Radically reducing the biggest source of hospital waste for GHG and cost reductions
Hope Hot Glass, but a Cooler Climate Glass blowing, an ancient art that has always had a dreadful carbon footprint, finds ways to improve.
