This Handbook is a technical background document to Policy Paper 1 Comprehensive Green Public Procurement System as a Mechanism for Implementing the Concept of Managing All Types of Waste in the Republic of Kazakhstan for 2026–2030 (Government Decree of the Republic of Kazakhstan No. 1201 of 31 December 2025), prepared under the EU SWITCH-Asia Policy Support Component programme (2024–2026). The Handbook sets out the full content of the 41 standard positions of construction materials and engineering equipment delegated to it by Policy Paper 1 — items 1–41 in the classification proposed in PP1 Tables 61 and 62, distributed across 12 established categories (A–M). For each position, the Handbook provides regulatory standards from three jurisdictions (EU, Japan, Asia); Kazakhstan equivalents — intergovernmental standards (GOST) and national standards (ST RK) — with references to corresponding international standards; a market-readiness assessment; a three-tier price analysis; green public procurement environmental criteria; per-unit carbon benefit; and environmental requirements for the technical specification to be used on the public procurement web portal of the Republic of Kazakhstan (goszakup.gov.kz). The intended audience comprises public procurement specialists, sustainable construction experts, and the International Centre for Green Technologies and Investment Projects (IGTIPC) as the single operator of the registries of green technologies (L1), green products (L2), and green services and works (L3). This Handbook serves as the technical data source for the green products registry (L2). The architecture of the L1→L2→L3 cascade is set out in PP1 (Section 3.4) and PP2 (Section 3.1).
