To address the danger that greenhouse gas (GHG) emissions from aircraft pose to public health and welfare, the U.S. Environmental Protection Agency (EPA) is set to propose an aircraft CO2 emissions standard.

There is considerable interest in India in moving toward fuel-efficiency standards based on simulation modeling, and particularly in exploring the feasibility of using the Vehicle Energy Consumption Calculation Tool (VECTO) developed by the European Commission.

This working paper details and analyzes a global, transparent, and geographically allocated carbon dioxide emissions inventory for commercial aviation for calendar year 2018.

This study assesses the fuel efficiency of U.S. airlines on domestic operations in 2017 and 2018. Revenue passenger miles (RPMs) increased 10% and departures increased by 4% from 2016 to 2018. Fuel efficiency in terms of RPMs per gallon of fuel consumed improved by 3%.

Market projections for electric vehicle growth in India are ambitious but uncertain. In addition, the passenger car CO2 standards enforced in India are amongst the most lenient, and the super-credit multipliers available for electric vehicles are more generous compared to global practices.

This paper examines the potential of two innovative technologies—wind-assist and hull air lubrication—to help reduce emissions from new and existing ships.

This sets out the impact of current global policies, the changes in the global fleet and new global efficiency targets to accelerate the uptake of clean and efficient vehicles for vehicle efficiency.

In October of 2018, the Department of Transport of South Africa received cabinet-level approval to move the Green Transport Strategy (GTS) forward. The GTS is South Africa’s governmental guidance document that sheds light on pathways to decarbonize the country’s transport sector.

This analysis examines the benefits and costs of fuel-saving technologies for new heavy-duty vehicles (HDVs) in India over the next 10 years and explores how various scenarios for the deployment of vehicles with these technologies will impact petroleum consumption and carbon dioxide (CO2) emissions out to 2050.
