Based on SDG 9 “Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation” the investable sub-goals are:

9.1 Sustainable & Resilient infrastructure
Transportation infra
Investible entities that:
- construct or operate public transportation infrastructure (train, metro, ferry) with a focus on affordable and equitable access for all
- construct or operate roads, ports or airports, e.g. in highly undeveloped regions
Social infra
Investible entities that:
- construct or operate schools, hospitals
Waste infra
Investible entities that:
- construct or operate waste collection infrastructure and waste treatment facilities that are aimed at improving resource efficiency (reduce, reuse, recycling)
Communications infra
Investible entities that:
- construct or operate networks, antenna towers, fiber cables, internet providers with a focus on affordable and equitable access for all, especially for connecting the unconnected in disadvantages areas.
Energy infra
Investible entities that:
- transmit and distribute electricity with a focus on affordable and equitable access
- transmit and distribute electricity generated from renewable sources (e.g. wind farm power cables) or provide access to electricity markets which are already >80% renewables or are increasing renewables-based generation (by >1% pa over 3 year average)
- provide equipment or services for smart grids, local storage, behind the meter energy storage, energy transition infrastructure (e.g. grid improvements) and electrical transportation (e.g. EV charging stations)
- distribute alternative fuels (including hydrogen, fuel cells and advanced biofuels)
X Not transmission and distribution driving the expansion of coal or nuclear generation capacity, see SDG7.
9.3 Access of small-scale enterprises to financial services in particular in developing countries
Investible entities that:
- provide loans are provided to small and medium-scale enterprises
- provide electronic payment systems and other financial services enabling small and medium-scale enterprises to access the traditional finance sector
! Additional scrutiny on high risk and predatory lending practices may be warranted
9.4 Upgrade infrastructure and retrofit industries to make them sustainable
Resource efficiency
Investible entities that:
- provide equipment and services that increase resource and energy efficiency (see also SDG 7 and SDG 12) provide equipment and services for recycling and utilization of waste and by-products
- supply recycled materials
- provide equipment and services for Carbon Capture, Utilization and Storage
The SDGs and SDG sub-goals have been translated from an investor perspective into the SDI taxonomy of product categories that are considered solutions contributing to the SDGs. The full SDI Taxonomy can be found here. When evaluating a company, the starting point is the classification of its products and services within the SDI product categories. The size of the positive contribution is calculated from the associated revenues (sales).
