Governments across Europe and Asia are urging households to keep emergency supplies and prepare to manage without outside help:

• UK - 3 days
• Japan - at least 3 days, preferably a week
• Sweden and Norway - at least 7 days
• Finland and Denmark - 3 days
• Germany - ideally 10 days
• Austria - 10-14 days
• France and the Netherlands - 72 hours
• Estonia - 7 days
• Latvia - 72 hours of self-sufficiency, with supplies for 3-7 days
• Lithuania, Poland, Luxembourg, Belgium and Czechia - generally 72 hours
• Ireland - emergency booklet advising households to prepare essential supplies
• Taiwan - at least 7 days of home supplies, plus a go-bag
• Switzerland - about a week of food and 3 days of water
• EU - a minimum 72-hour preparedness goal

In the United States, civilian guidance recommends supplies for “several days.” Separately, reports on the Pentagon’s FORTRESS initiative describe a goal for major military bases to sustain essential operations independently for at least 90 days.

These recommendations cover disruptions ranging from severe weather and power failures to cyberattacks and conflict. Some have been in place for years.

Prepare calmly. Build supplies gradually. Stay informed.
