Models, modelling tools and datasets

In our work for a wide range of clients CE Delft makes frequent use of computer models and modelling tools, many of which are designed in-house.
Models are the computer programs used to calculate environmental impacts and that put our research on solid quantitative footing.
Modelling tools are user-friendly and versatile interfaces with which our clients – and their clients – can specify their own parameters and calculate the impacts themselves, tailored to their own specific circumstances. In design, mode of operation and simplicity or complexity, each tool is tailored to the client’s particular requirements.
Datasets provide the relevant environmental data on products or materials, and are generally condensed into a format like Excel or SimaPro. If your firm already uses SimaPro, these datasets can be ordered from CE Delft, imported and used for in-house calculations on environmental and other issues.

 


Feebate simulation tool passenger vehicles

For the International Council on Clean Transport (ICCT) we developed a feebate simulation tool aims to provide users (governments, NGO’s) with insight into the various possibilities for designing a feebate system for a particular country and the vehicle and financial impacts that can be expected for this country with the design choices made. This, in turn, can assist users of the tool in national-level policy discussions. The user does not need any data to use the tool, as several default countries have been included in the tool which can be used for comparison. A user guide has been developed that provides clear instructions on how to use the tool and these tabs in particular. Background information on feebate schemes, design options, and the pros and cons of different designs has been included in the annexes of this user guide.

Environmental Impact of Packaging tool

This tool calculates the carbon footprint and embodied energy content of coffee and tea packaging. Users select the packaging type of interest and the data are then computed for the entire lifecycle, from raw materials and production all the way through to transport and waste disposal.

In this versatile modelling tool, users have numerous options for specific data input. The impact of the packaging is calculated per cup of coffee/tea, per consumer packaging unit (pack of coffee/tea), or for all types of packaging individually.

SITA Ecoscan: environmental impacts of waste disposal

For SITA, CE Delft has developed the Ecoscan, which can be used by industries to determine the environmental impacts of their waste disposal practices and how these can be reduced. CE Delft calculated the relevant indices, elaborated the environmental calculations and designed the de modelling tool on which the web version is based. The Ecoscan calculates not just CO2 emissions, but a range of other environmental impacts, too. naar boven

SuperWijzer app: meat, butter, cheese and eggs

For the animal welfare group Varkens in Nood and Greenpeace, CE Delft has calculated the impacts of the entire supply chain of 121 animal-derived protein sources like meat, milk and butter on climate and biodiversity (land-use quality). This data was used to create the SuperWijzer app, a free smartphone app that consumers can use to scan the barcode of virtually any protein product found on Dutch supermarket shelves and see how it scores on the two environmental criteria as well as with respect to animal welfare. naar boven

LCA on film

Which environmental parameters and endpoints should you study in an LCA study, and how do you go about weighting them? It’s always tricky to explain the results of this kind of study in a way that is clear and comprehensible to non-experts. On a commission from Nomacork, CE Delft has created a short animated clip explaining an LCA study on natural cork.

Modint Ecotool for textile products

For Modint, the Dutch trade association for clothing, fashion accessories, carpet and (interior) textiles, CE Delft has developed the Modint Ecotool. With this tool, textile producers can quantify the cradle-to-grave environmental impact of their products. Users define their own particular product, from the fibres and production processes all the way through to product use and disposal, as well as the specific technologies used. The results for five environmental impacts are then reported on a ‘score card’. CE Delft designed and developed the tool, elaborating the underlying software and providing the background environmental data and modelling calculations. naar boven

Tools for modelling potato waste processing

Under the so-called MJA/MEE scheme, numerous companies in the Netherlands have made long-term pledges to reduce their energy consumption, reporting on their achievements annually. For companies in the potato processing sector, CE Delft has developed a computer tool permitting simple calculation of the energy requirements and potential energy savings of four processing routes for four potato waste streams by entering just a handful of parameters.  For this tool CE Delft provided the core indices and environmental calculations as well as the computing software. A web version has also been developed. naar boven

CO2 Performance Ladder

The CO2 Performance Ladder is a software tool today used by numerous companies in the Netherlands to reduce the environmental impact of their  operations, with a growing number also using it in the context of project outsourcing and procurement. In 2011 CE Delft updated the in-house-developed datasets, including new indices for biofuels and district heating, for example. During the development phase CE Delft also advised on the methodology employed. The CO2 Performance Ladder is administered by SKAO. naar boven

Logistics Emissions Scan computes freight transport emissions

In a comparative study by TNO and the trade journal Logistiek CE Delft’s Logistics Emissions Scan scored high marks. The tool provides insight into freight transport emissions and was developed by CE Delft, the trade association EVO and Altimedes Consulting. For further information, click herenaar boven

STREAM datasets for environmental impacts of transport vehicles

For STREAM, the 'Study on Transport Emissions of All Modes', CE Delft has developed a database with recent emissions data on a very extensive range of transport vehicles. With STREAM, CE Delft helps companies establish tailor-made emission factors for CO2 and other air pollutants that make due allowance for type of freight, transport distance and company-specific vehicle load factors so they can compute the emissions associated with their operations. CE Delft can provide support in developing an emission calculator as an element of a logistics planning package or in making specific carbon-footprint calculations. naar boven

ABCO2

In collaboration with the CAPE Group, CE Delft has created a multimodal carbon emissions tool for the transport sector: ABCO2. The calculation methodology was developed by CE Delft, as was the tailor-made set of emission factors (g/tkm). ABCO2 calculates the CO2 emissions of the selected transport route and alternatives. CE Delft can provide support for environmental calculators in logistical planning software by developing calculation methodologies and defining tailor-made sets of emission factors. naar boven

TEMPO: Transport Elasticity Model for Policy Options

The CE Delft-designed freight transport model TEMPO calculates the transport and logistical impacts of policy measures. Transport effects are reflected in total transport demand, modal split and average trip length, logistical effects in changes in average vehicle load factors, routing and average fuel consumption.  CE Delft has used the TEMPO model in a range of projects, including studies on the effects of a kilometre charge for freight vehicles in the Netherlands and on the effects of pricing policies for all freight transport (road, rail, inland shipping) serving the Amsterdam-Paris corridor. naar boven

Shadow price dataset

Shadow prices can be used to put a financial value on environmental impacts. CE Delft had already developed a set of shadow prices back in 2002, and these were updated in 2010. At the same time a user manual was also created setting out possible applications of such prices in both the policy and commercial context. naar boven

Tool for energy efficiency in the built environment

For the Dutch Interior Ministry, CE Delft has developed a tool that allows users to chart the effects of a wide range of measures in the realm of energy efficiency. Users define their own boundary conditions for the model, such as minimum energy savings, maximum costs and degree of government intervention. The measures that best match these criteria are then graphically displayed for comparison. naar boven

MACH - Marginal Abatement Costs of Heavy-duty vehicles

At the request of the European Commission (DG Climate Action), CE Delft has developed a tool that establishes the marginal cost curves of CO2 abatement measures for heavy-duty road vehicles. Users enter their own assumptions on fuel prices and technology costs and lifetimes, which the model uses to generate cost curves for various vehicle categories. naar boven
