Decreasing the CO2 footprint related to business and commuter travel for companies presents a multitude of challenges. These challenges range from finding the objections of employees regarding EVs, and ways to overcome them, to determining what an ideal composition of a car fleet would be. At the same time the financial feasibility of all theses challenges have to be taken into account. If no (financial) benefits can be gained, a company is less likely to implement measures to reduce its CO2 emissions. Building on this, the main aim of this thesis is thus to find the barriers against electric driving for company car drivers in The Netherlands and find ways in which the company can aid in overcoming these barriers. Additionally, this research presents a thorough and general investigation into the yield and costs accompanying the installment of rooftop solar systems.  To determine the barriers amongst employees, a quantitative survey was conducted with 176 respondents. The survey was analyzed and generated with the help of TAM, and the results were then used to create three different CO2 reduction scenarios. After which it was possible to calculate cost and benefits associated with each individual scenario. In doing so the one-off and yearly investment costs were determined for both employer and employee. Based on the research done it is concluded that the barriers against the transition to EVs are similar for company car drivers and private car owners.  It is also concluded that the barriers found are similar for all companies in The Netherlands. Furthermore, by driving electrically, while commuting, companies can easily reach a CO2 reduction of 21.0%.  If companies then also use their rooftops to generate electricity, that can be used to charge the EVs, an additional savings can be realized of, in this case, 9.0%
