Declaration commitments include the following:

• Zero Emission Vehicles (ZEV) Alliance partners, including the state of California, the countries of Norway, the Netherlands and the United Kingdom, commit to zero (local) emission vehicles making up 100% of passenger vehicle sales as fast as possible and no later than 2050.
• The C40 Clean Buses Declaration – 24 megacities from every continent will switch, on average, more than 25% of their bus fleets to low and ultimately zero (local) emission buses, which represents over 42,600 renewed buses by 2020. The ultimate goal is to incentivize and be careful help manufacturers and other stakeholders (such as multilateral banks) understand the scale of global demand, and develop strategies to make these technologies more affordable for cities.
• United Nations Environment Program (UNEP) will launch a new programs of 15 pilots on electric busses, light duty vehicles and motorbikes in developing countries.
• Taxis Worldwide Initiative – 12 taxis companies from 11 countries, representing more than 20,000 vehicles, will introduce in their fleet by 2020, plug-in electric vehicles and assimilated, emitting less than 60 gCO2/km, at a rate of at least 33% of the vehicles entering their fleet.
• France, Spain and Portugal will work towards the development of electric recharging points and call for the deployment of such corridors worldwide.
• Urban Electric Mobility Initiative aims at 30% of new vehicles in cities being electric by 2030.

Fuel Efficiency Improvements. Launched in 2009, by the FIA foundation, the International Transport Forum (ITF), the International Energy Agency (IEA) and the United Nations Environment Program (UNEP), (4) The Global Fuel Economy Initiative (GFEI) aims at doubling the fuel efficiency of global light duty fleet of vehicles by 2050, which would result in a cumulative reduction of over 30 gigatons of CO2 by 2050. Reduction of light-duty vehicles’ fuel consumption can be achieved through the adoption of best standards, ban on imports of old vehicles, labelling schemes and various implementation measures. Additionally, a combination of weight reduction, optimized aerodynamics, improved powertrains (hybrid or electric) and tire-rolling resistance is required to achieve envisaged improvements in fuel economy. Since the 2014 New York Climate Summit, GFEI has triggered a strong momentum worldwide by engaging private partners as well as 40 new countries committed to work towards developing policies and regulations that improve fuel economy of light-duty vehicles. GFEI aims to be working with 100 countries within the next year.
