Earth Economics quantified the benefits created by developing GSI on StreetWell properties. Valuing non-market benefits makes GSI projects more attractive to socially conscious investors. Planting 25 new trees and replacing 2,500 sq ft of sidewalks with raingardens would create $2M in ecosystem services over 25 years, returning $7 for every $1 invested.

Earth Economics has quantified the ability of investments home hardening in California to support jobs, economic activity, and tax revenues throughout the state. Each dollar invested in retrofitting returns about $1.70 in total economic activity. If homes were moderately hardened, it could cost $16-$20B, but would also support 74,000-92,500 jobs, add $21-$26.5B to the economy.

The county's open spaces generate at least $2.96B in value each year. Over a century, this amounts to an asset value of at least $138.9B—conservation is a smart investment in the county's future.

We supported Bluewing Civil Consulting, Headway Environmental, and the Vermilion Soil and Water Conservation District, assessing impacts of water control alternatives on ecosystem services in the Lower Vermillion Watershed, Louisiana.

Our high-level valuation of co-benefits created by natural ecosystems in the Ohio River Basin found that the 68M acres of natural ecosystems produce at least $50B in annual benefits, and $1.17T in benefits over 30 years.

Earth Economics and the Everglades Foundation conducted an economic assessment of Everglades ecosystems to show the importance of natural capital in sustaining the region’s economy and quality of life.
