Glossary

Mode of Transport

The way how people or goods get moved from A to B. Common modes of transport are walking, cycling, driving by car, bus, train, sending goods via trucks or ships or planes. 

prewiew
Mode Split or Modal Split

This described the percentages of transportation types used. This usually refers to certain geographical areas or use cases, such as commuters in the Paris area. 

prewiew
Molten Salt Battery

A type of battery that utilizes molten salts as an electrolyte.

Multi-modal Travel

Traveling which allows to select different means of transport for the same ride – but using only one means of transport per trip, e.g. either one time take a bike, next time a car, another time a bus. Also see Inter-modal Travel. 

prewiew
Nationally Determined Contribution (NDC)

Submissions by countries that have ratified the Paris Agreement which presents their national efforts to reach the Paris Agreement’s long-term temperature goal of limiting warming to well below 2°C. New or updated NDCs are to be submitted in 2020 and every five years thereafter. NDCs thus represent a country’s current ambition/target for reducing emissions nationally. 

prewiew
NEDC

A cautionary tale in use of the word “new”, the New European Driving Cycle (NEDC), last updated in 1997, was designed to assess the emission levels of car engines and fuel economy in passenger cars. It has fallen out of favour as manufacturers were configuring their cars’ performance for the NEDC test, rather than the NEDC measuring their cars’ real world performance. When it comes to electric vehicles, the NEDC gives quite a generous assessment of range. 

prewiew
Neighbourhood Electric Vehicle (NEV)

BEV’s that are limited to streets with lower speed limits, typically around 45mph. NEV’s are all-electric and can be recharged using a standard outlet. 

prewiew
Net Zero CO2 Emissions

Net Zero CO2 Emissions are also referred to as carbon neutrality. Net zero carbon dioxide (CO2) emissions are achieved when anthropogenic CO2 emissions are balanced globally by anthropogenic CO2 removals over a specified period.

prewiew
Net Zero Emissions

Net Zero Emissions are achieved when anthropogenic emissions of greenhouse gases to the atmosphere are balanced by anthropogenic removals over a specified period. Where multiple greenhouse gases are involved, the quantification of net zero emissions depends on the climate metric chosen to compare emissions of different gases (such as global warming potential, global temperature change potential, and others, as well as the chosen time horizon).

prewiew
New Mobility

This is a buzzword describing new and upcoming mobility options and their combination into an integrated traffic system. Not everything labeled as “new” is really new, e.g. ride sharing is as old as the use of horses and buggies and even electric scooters were known in the 20’s of the last century. New Mobility is sometimes also referred to as Smart Mobility.
