EPHI Joins UNEP-Coordinated Global Wastewater Initiative to Advance Paris Agreement Implementation

EPHI expands its contribution to climate adaptation and Paris Agreement transparency through integrated drinking water and wastewater systems.

Press Release

Chicago, Illinois – January 22, 2026
Environmental & Public Health International® (EPHI) announced that it has joined the Global Wastewater Initiative (GWWI), a United Nations Environment Programme (UNEP) coordinated platform. The engagement supports implementation of the Paris Agreement by strengthening climate-resilient drinking water systems and their interaction with wastewater and sanitation, while advancing transparency objectives under Article 13.

Supporting Paris Agreement Article 13 Through Water Infrastructure Data

The Enhanced Transparency Framework under Article 13 of the Paris Agreement relies on credible, consistent information on climate adaptation actions and related infrastructure investments. Drinking water infrastructure data are a critical upstream input to understanding system resilience, public health risk, and downstream wastewater and sanitation performance.

Through its engagement in the GWWI, EPHI contributes data-driven tools that support sub-national adaptation planning and enable improved tracking of drinking water system investments with implications for integrated water and wastewater management.

Linking Drinking Water and Wastewater Systems for Climate Adaptation

Climate-resilient drinking water systems directly affect wastewater and sanitation performance, water quality, and public health outcomes. Engagement through the GWWI situates drinking water infrastructure planning within a broader systems context.

The UNEP-recognized Lead Service Line Replacement Cost Calculator® (LSLRCC) supports climate-resilient drinking water planning by enabling communities to model infrastructure needs, assess future cost risks, and inform adaptation decisions.

Independent Validation and Applied Infrastructure Use

The LSLRCC has been independently covered by infrastructure and public works publications as a practical tool for strengthening drinking water systems. Its applied use in estimating lead service line replacement costs demonstrates how decision-grade drinking water infrastructure data support climate adaptation and public health protection, while informing transparency objectives under the Paris Agreement and integrated water system planning.

Advancing the UN Sustainable Development Goals

Strengthening climate-resilient drinking water systems contributes directly to progress on the UN Sustainable Development Goals, including SDG 6 on clean water and sanitation, SDG 3 on health, and SDG 13 on climate action. Engagement through the GWWI situates drinking water infrastructure within integrated water and sanitation systems that support Paris Agreement implementation.

“Climate adaptation begins with resilient drinking water systems,” said Anthony Ross, Founder of Environmental & Public Health International. “Through the Global Wastewater Initiative, EPHI is advancing practical, data-driven infrastructure planning that supports the Paris Agreement and the Sustainable Development Goals.”
