A group representing major internet companies including Facebook, Amazon and Alphabet said on Tuesday it backed modernizing U.S. data privacy rules but wants a national approach that would block California’s new regulations that take effect in 2020.

“Data has revolutionized every part of our economy and our lives, both online and offline. Businesses and nonprofits of all sizes, in every sector of the economy, have integrated data into their products and services to the benefit of consumers, which is why internet companies support an economy-wide, national approach to regulation that protects the privacy of all Americans,” said Internet Association President and CEO Michael Beckerman.

The group released six principles and policy considerations to modernize national privacy legislation. According to the group, a national framework should specifically preempt the patchwork of different data breach notification laws in all 50 states and the District of Columbia to provide consistency for individuals and companies alike.

The Internet Association represents more than 40 major internet and technology companies.
