Challenge: Increasing sustainability requirements from international buyers meet lack of understanding and awareness at supplier level

Objective: Improved local capacities and awareness on new requirements for export readiness and competitiveness

Approach: Establish RBH with suitable partner institutions for a long-term anchoring of servies on the ground

Impacts: Since end of 2022 over 2500 suppliers in 8 countries have made use of the support services of the RBH

This guidance is primarily aimed at public procurers involved in a range of contracting agreements related to building materials and products. This includes the purchase of building materials for construction works, but may also extend to material extraction, manufacturing, building, retrofit, refurbishment, design, interior fit out, and end-of-life demolition or deconstruction processes. There are a variety of roles within the procurement cycle that the guidance can support, from commissioning, category management, tender preparation and evaluation, to contract management.

Este documento aborda la gestión de sustancias químicas de preocupación y algunos

aspectos de sostenibilidad, incluyendo la circularidad en la compra pública sostenible

(CPS) de los AEE, específicamente de computadores, impresoras y acondicionadores de

aire, proporcionando además una orientación clara a las entidades públicas sobre cómo

incluir criterios técnicos para la adquisición de dichos equipos.

Plastics are used in a vast range of building components, such as seals, windows and doors, roofing, internal and external finishes, paints, panels, varnishes, stains, pipes, guttering, cables, floor coverings, membranes, formwork, supporting structures, building skins and insulation. However, their benefits come at a growing cost to the environment and public health.

The construction industry consumes 20% of all plastics and 70% of all polyvinyl chloride (PVC) produced globally each year. Exponentially greater amounts are being produced and used, with 8.3bn tonnes of virgin plastics produced worldwide between 1950 and 2017 and global output predicted to double by 2050.

The transition to sustainable construction will involve fundamental changes in the way buildings are designed, manufactured, built and operated. As society pushes up against established planetary boundaries, professionals working in the built environment need to identify how to change our practice.

Healthy Building Network's report on post-consumer carpet feedstocks calls for eliminating over 40 highly toxic chemicals in carpets that threaten public health and impede recycling. These toxics are known to cause respiratory disease, heart attacks, cancer, and asthma, and impair children's developmental health. The report outlines strategies to protect public health and the environment by improving product transparency, eliminating dangerous chemicals from carpets, and increasing carpet recycling rates. It also reveals surprising efforts in the industry to remove many of these toxic substances from carpet design.

HBN tested 94 commercially available paint products for the presence of harmful per- and polyfluoroalkyl substances (PFAS), called “forever chemicals”. Approximately 50% of ‌paints tested positive for fluorine, a marker of PFAS. Review the details of our findings and the recommended actions you can take.

UNEP's new Eco-innovation Building Materials Supplement was created to respond to the building material sector's need for more guidance in building resilient, competitive, and sustainable business models for SMEs. Designed together with Bioregional, pilot implementation support of the National Cleaner Production Centre (NCPC) Sri Lanka and to be read alongside UNEP's Eco-innovation Manual, the supplement provides specific examples, learning case studies, and advice on applying the eco-innovation methodology within the building materials value chain.

Per- and polyfluoroalkyl substances (PFAS) are a large class of thousands of synthetic chemicals that are used throughout society. However, they are increasingly detected as environmental pollutants and some are linked to negative effects on human health.

This page from the European Chemicals Agency provides background on PFAS chemicals and their use in a number of products, including construction materials, paints and chrome plating.
