ICCT: California’s Advanced Clean Trucks regulation

Sales requirements for zero-emission heavy duty trucks. On June 25, 2020, the California Air Resources Board (CARB) adopted the final rule for new standards that require the sale of zero-emission heavy-duty trucks (HDTs), starting with the 2024 model year. The Advanced Clean Trucks (ACT) regulation, first of its kind in the world to require manufacturers to sell increasing percentages of zero-emission trucks, is expected to reduce the lifecycle emission of greenhouse gases (GHGs) and eliminate

ICCT: CO2 emissions from commercial aviation – 2013, 2018, and 2019

This report updates a working paper released last year, and details a global, transparent, and geographically allocated carbon dioxide (CO2) inventory for three years of commercial aviation. For the first time, we estimate absolute emissions and carbon intensity per passenger by both seating class and aircraft class. While results show that global passenger operations are becoming more fuel-efficient, this is not happening fast enough to offset traffic growth. Commercial traffic has increased nearly four times

CLASP: Global Opportunities to Advance Water Efficiency

CLASP assessed the viability of introducing water efficiency policies in the world’s top-18 carbon-emitting economies in the appliances sector, focusing specifically on policies for faucets and showerheads. CLASP ranked each country by the relative urgency and potential for impactful policies based on factors such as hot water consumption, pressure on water resources, and projected population increases. CLASP also assessed the viability of successfully implementing water efficiency policies, based on prerequisites such as existing water or

CLASP: 3H Hybrid Heat Homes

An Incentive Program to Electrify Space Heating and Reduce Energy Bills in US Homes Heat pumps are a critical technology on the path to net-zero emissions, but their deployment to date has been slow. This document proposes a low-barrier, least-cost policy package to rapidly deploy efficient space heating and cooling solutions in the United States. It aims to “raise the floor” for electric space heating in the residential HVAC market, delivering 45 million new installations
