A national action plan on green public procurement, issued for public consultation on Thursday, proposes that ministries should be bound to opt for environmentally-friendly products in all calls for tender they issue by 2025.
The tenders will be monitored by Environment Ministry officials and vetted if they do not follow the rules, environment and climate change director Ruth de Brincat said.
The proposed action plan is the second of its kind, with the first having required that half of all government tenders have environmental considerations. That target was exceeded last year, when 67 per cent of procurement featured environmentally-friendly considerations, Ms de Brincat added.
The new plan also suggests that at least 15 per cent of all waste generated from demolition and excavation works for public buildings and construction should be reused.
This would also help create a market for reconstituted stone, Ms de Brincat said.
Construction and waste accounted for over 69 per cent of waste generated in 2016.

Environment Minister Jose' Herrera, who also addressed the press conference, pointed out that the Environment and Resources Authority is preparing a plan for land reclamation.
The document also calls for measures to encourage people to repair, rather than replace products. Such measures could include readily-available spare parts.
The public consultation on the document closes December 22.
