Green Century’s Balanced Fund, which is a mix of equity and fixed-income assets, offers investors the opportunity to align their values with their financial goals. The Fund’s fixed-income portfolio is comprised currently of more than 70% green bonds, including the San Francisco Bay Area Rapid Transit (BART) green bond, which funds projects that expand sustainable public transportation, reduce greenhouse gas emissions, and strengthen climate resilience across the Bay Area.
For over 50 years, BART has connected Bay Area communities. Today, its green bond program drives forward its sustainability initiatives, including energy-efficient trains, renewable energy, and pollution-reduction initiatives—building a cleaner, more resilient future.
Transportation is the largest source of greenhouse gas emissions in the country, and BART is helping change that. Each ride offers a clean, efficient alternative to driving—about three times more efficient than a solo car trip—and prevents more than 25 pounds of CO₂ emissions per round trip. By taking cars off crowded roads, BART is cutting the pollution that fuels climate change and harms air quality.
BART’s sustainability innovations further amplify this impact. Its new train fleet, called the Fleet of the Future, is 100% electric, with 97% of its power sourced from clean energy suppliers. The trains are built with lightweight, recyclable aluminum that both reduces energy use and enables easy recyclability at the end of their lifetimes. Additionally, the trains feature LED lighting and smart door sensors that further reduce energy loss.
BART is also investing in creative strategies to improve climate resilience. In areas prone to wildfire, the transit system brings herds of sheep to graze on brush along railway lines. This low-tech, but effective, solution reduces fire risk, lowers costs, and avoids the emissions that heavy machinery would otherwise produce.
With fixed-income holdings like the BART green bond, Green Century’s Balanced Fund supports and helps fund the protection of a cleaner, more sustainable planet.
A sustainable investment strategy which incorporates environmental, social and governance criteria may result in lower or higher returns than an investment strategy that does not include such criteria.
