Despite the Paris Agreement and numerous actions, climate change seems to be inevitable. Events and phenomena as forest fires, hurricanes, floods, and melting glaciers can hardly be explained solely by natural changes in the weather. We need to do our very best to limit the climate change, but also a thermal increase below 1.5 ℃ affects our planet. Up to now, most research has been devoted to mitigation, how can we reduce and preferably prevent the climate change. This is particularly valid for the concrete research that in recent years has been dominated by making the concrete material more environmentally friendly or greener by replacing parts of the Portland cement with industrial by-products, e.g., fly ash, ground-granulated blast-furnace slag and silica fume. However, in order to protect our built environment for higher sea levels, greater floods, forest fires close to urban areas, and possible increased wind loads, measures to protect our built environment, not least our infrastructure are urgent. The years 2030, 2040 and 2045, which frequently are mentioned in the environmental agreements, are coming closer. Concrete has a large role to play both in protecting structures such as barriers around cities close to the sea or rivers and for strengthened existing or new structures that can withstand increased loads and attacks from water, moisture, wind, and fire. The paper describes and discusses research needs focusing on Scandinavian conditions identified in an ongoing pilot study.
