What is 'hidden' impact?

We as Western consumers have much more impact than we think. Not only in our daily activities in and around the house or weekly at the gaspump, but mostly on the other side of the world, by producing and transporting the things we buy and use daily. Most of the impact has already taken place even before we buy a product in the shop.

If you include that hidden impact, you can effectively improve the sustainability of your lifestyle. Let’s go!


Furthermore, we often only look at one type of impact, such as CO2 or plastic. Suppose you only pay attention to packaging, you could theoretically continue to eat meat and fly.

Think Big Act Now takes all types of impact into account, thus tackling the blind spots in our thinking about sustainability. That way, your sustainable choices actually make a difference.

The impact top 10

The top 10 shows us where we cause most of our impact. But more importantly, it also shows us what we can best work with if we want to become more sustainable.

It turns out that the average Dutchman’s stuff is number 1 in the Impact Top 10. Our car takes up number 2. Thereafter come the impacts of our housing and eating meat and fish. At number 5, there’s flying and at number 6, all food except meat, dairy and eggs, is listed, meaning vegetable food and drinks. After that, clothing and textiles, dairy and eggs, personal care in the bathroom and public transport, being the smallest of the impact top 10.

In the spring of 2020 research bureau CE Delft re-examined the top 10 categories. The new data has caused a number of shifts compared to the previous impact top 10. The top 10 shown on the right and described above is the most recent version (2020).
