We only accept open sources in impact analyses. What does this mean?
Sources need to be freely accessible without any restrictions. The reason is that readers and raters need to be able to read any sources documented in the analysis and confirm the cited information.
Many sources are open-sourced, such as Wikipedia, certain online newspapers like the Guardian, and data providers. However, some sites are not freely accessible, like The Financial Times. You need to pay to access their articles, so we do not accept them. Finally, some sites are semi-open: visitors get limited access (think Statista) or only up to a certain amount of visits (for example, the CDP). These sites can be accepted if the information is viewable by everyone; otherwise, they might be rejected. The decisions remain on Reviewers, depending on the situation.
