This article contributes to the economic literature on pure and impure public goods by considering two alternatives for contributing to the public good climate protection: offsetting carbon emissions from conventional consumption or paying higher prices for climate-friendly products. We empirically examine a wide range of motives and their impact on individuals’ choice in favour of these two alternatives relying on data from representative international surveys. Our results indicate that environmental awareness, warm glow motives and the desire to set a good example have the most robust effects on both climate protection activities in Germany and the United States. However, some motives differ considerably between both alternatives and the two countries. A green identity enhances the willingness to pay a price premium for climate-friendly goods or services in Germany, while social norms seem to be of much higher relevance in the United States. Our results further suggest that the choice of climate protection activities, especially of carbon offsetting, entails a high degree of uncertainty.
