Lambeth has become the first London Borough to adopt the standards, which compel the council to "ensure, using enforcement powers where expedient, that the planting required by planning approvals is installed and maintained."
The motion, proposed by Liberal Democrat Councillor Diana Braithwaite, was given unanimous support at a full council meeting last week.
It pledges council support to exemplar schemes and the lobbying of local MPs to promote the principles of the Greening the UK campaign within Parliament.
The Greening the UK campaign has been highlighting the fact that there has been a 50% reduction in soft landscaped areas on new developments over the past decade; and that only 50% of the green planting outlined in approved planning documents is ever delivered.
Councillor Diana Braithwaite said: "We have to ensure that green spaces, trees and plants are integral in the design of all new developments and that they are not merely an afterthought."
Horticultural Trades Association director general David Gwyther added: "The planting of trees and plants in urban areas has immense benefits for our social, health and environmental well being - with particular impact in large conurbations like London.
"I am encouraged by the news that Lambeth is the first London Borough to adopt the Greening the UK model motion and I hope that other Boroughs will follow suit and join the campaign."
