After California, now the Washington State senate has adopted a data protection and privacy act that takes the EU General Data Protection Regulation (GDPR) as an example to emulate.
This is definitely a hoped for effect of the GDPR when it was launched. European environmental and food safety standards have had similar global norm setting impact. This as for businesses it generally is more expensive to comply with multiple standards, than it is to only comply with the strictest one. We saw it earlier in companies taking GDPR demands and applying them to themselves generally. That the GDPR might have this impact, is an intentional part of how the EC is developing a third proposition in data geopolitics, between the surveillance capitalism of the US data lakes, and the data driven authoritarianism of China.
To me the GDPR is a quality assurance instrument, with its demands increasing over time. So it is encouraging to see other government entities outside the EU taking a cue from the GDPR. California and Washington State now have adopted similar laws. Five other States in the USA have introduced similar laws for debate in the past 2 months: Hawaii, Massachusetts, New Mexico, Rhode Island, and Maryland.
