Mission Statement

Founded in 1994, ECOSS’ mission is to educate and empower businesses and diverse communities to implement environmentally sustainable practices. We represent and create collaboration between key, and often-conflicting segments of Seattle's neighborhoods: businesses, residents, municipalities, environmental organizations, and community groups. Our efforts forge much-needed connections between these different sectors. We ensure equitable access to knowledge and resources by bridging language, cultural, and technical gaps. Our work focuses on delivering resources and education on water quality, resource conservation, clean energy, and green space access. Our work focuses on delivering resources and education on water quality, resource conservation, clean energy, and green space access. We envision thriving communities that are environmentally sustainable and equitable. Our roots are in addressing the imbalance of environmental resources and services available to the South Park neighborhood and lower Duwamish River.

CharityAI™ rates charities from 0 to 100 using public filings (IRS Form 990 and the equivalent registries outside the US) together with the information the charity itself provides on DonationX. Ratings are recalculated every quarter, without human bias, and shown as stars.

Four pillars

Financial strength30%

Program expense ratio, fundraising efficiency, operating reserves, liabilities and revenue diversification, compared with similar organizations.

Reliability20%

Standing with the registry, filing history, verification and how complete the profile is.

Effectiveness25%

How much goes to programs and how consistently the organization delivers them.

Impact25%

The outcomes the charity reports on DonationX: people served, cost per service and results.

Stars

★★★★★ 80–100 ★★★★☆ 60–79 ★★★☆☆ 40–59 ★★☆☆☆ 20–39 ★☆☆☆☆ 1–19

A pillar with no data counts as zero. Without impact metrics the score is capped at 59 (three stars): only the charity can supply that data.
The coverage grade (A to D) says how much filing data the score rests on; NONE means there is not enough to rate.
An organization that is not in good standing with its registry (for example a revoked tax exemption) is shown as Not rated.
"Compared with peers" places the charity's key ratios against organizations of the same country, sector and size.
