It follows an adjournment debate in the Commons last week in which Liberal Democrat MP Bob Russell highlighted the work of HTA campaign Greening the UK.
He also called on decentralisation and planning minister Greg Clark to increase urban green planting on new and existing developments.
Russell said this could help local authorities and developers achieve Government sustainability and carbon reduction targets, reduce crime levels and improve hospital recovery rates.
"Urban planting is not just nice to have. We need a more systematic approach to the issue," added Russell.
Clark acknowledged the importance of green infrastructure and highlighted the role of the Localism Bill in protecting green space.
However, he failed to make any reference to urban planting in relation to the National Planning Policy Framework.
HTA business development director Tim Briercliffe said: "The Government has taken steps in the right direction.
"But, with no specific reference to urban planting made with regard to the National Planning Policy Framework, there is still further progress to be made."
