Emissions modelling

Since the early 1980s, emissions calculation models have been the primary method for determining current and future energy consumption, emissions of greenhouse gas and harmful substances in the transport sector, and for assessing the necessity and impact of measures designed to reduce emissions. Our TREMOD model plays a defining role in the configuration and ongoing development of emissions modelling in the transport sector.

Determination and modelling of CO2 emissions from motor vehicle traffic

What are the CO2 emissions of passenger cars and light commercial vehicles in reality? This question was investigated in the present study using empirical data and new modelling approaches.

Ecological assessment of different types of transport

Which means of transport has the least environmental impact? This question is answered in a new study by ifeu in cooperation with INFRAS and Öko-Institut.

Climate Balance of Caravanning

Do travelling with motorhomes and caravans have a smaller carbon footprint than other forms of travelling? The study compares the emissions from driving, vehicle and building manufacture, on-site…

Greenhouse gas emissions of the German travel mobility

Travel generates large amounts of greenhouse gas emissions that have not yet been fully recorded. Travel mobility represents about half of the total mobility of nationals, half of it is abroad.

Update of the models TREMOD/TREMOD-MM for emission reporting 2020 (reporting period 1990-2018)

The emission calculation models TREMOD and TREMOD-MM are the most important data sources for energy consumption and pollutant emissions of transport and mobile equipment and machinery in Ger-many. A…
