The Colorado River

The Environmental and Energy Study Institute (EESI) held a briefing highlighting strategies for improving the resilience and restoring the health of the Colorado River and its tributaries. The Colorado River basin serves as an essential source of agricultural, residential, and commercial water for communities and tribes in Wyoming, Colorado, Utah, Arizona, New Mexico, Nevada, and California as well as our neighbors across the border in Mexico. However, the river faces severe water stress, resulting in dwindling reservoirs. This water stress, exacerbated by climate change, threatens to degrade the river and jeopardize the ecosystems dependent on it.
This briefing focused on the role of federal policy in supporting stakeholders across the West as they addressed the impacts of drought and water stress through effective water conservation, measurement, and allocation. Panelists discussed the importance of collaboration between tribes, industry, communities, and local and federal government to restore river vitality and ensure equitable water availability for generations to come.

Clean Manufacturing in America

This briefing highlighted the ways in which onshoring the manufacturing of clean energy, energy efficiency, and electric vehicle components increases American competitiveness, secures U.S. supply chains, and creates jobs. According to the 2024 Sustainable Energy in America Factbook, in less than two years, companies announced more than $123 billion in investments in over 100 U.S. manufacturing facilities as a result of the Inflation Reduction Act. These new domestic manufacturing operations are making a diverse set of products—from solar panels and batteries to computer chips and wind turbines—in locations across the country. Research from E2 finds that these manufacturing plants are expected to create 67,000 jobs in rural areas. 
Panelists discussed how this growth in domestic manufacturing supports the clean energy transition and helps meet increasing demand, all while reinvesting in the communities in which these factories operate. The briefing also explored recent Congressional actions that spurred this manufacturing boom, as well as possible policy opportunities to leverage the momentum.

Understanding the Budget, Reconciliation, and Appropriations

This briefing explained the processes, rules, and norms that underpin the budget, reconciliation, and appropriations debates happening right now on Capitol Hill. It explored the relationship between the presidential budget, annual appropriations, and budget reconciliation. Panelists described the different stages of the appropriations cycle and how the process interfaces with other legislative activity on the Hill. The briefing highlighted ways Congressional staff—working both on and off the budget and appropriations committees—can engage with the conversations on fiscal year (FY) 2025 appropriations, FY2026 appropriations, and budget reconciliation.

Navigating Climate Information for Effective Policy-Making

Ready to make a difference in climate policy, but not sure where to start? We have you covered. The Environmental and Energy Study Institute (EESI) invites you to view our start-of-the-new-Congress briefing series, Climate Camp. We review climate science, cutting-edge innovations, and the role of the legislative process in climate mitigation and adaptation.
EESI’s first Climate Camp briefing served as an interactive refresher on the drivers of climate change and the latest deployable solutions to address the challenge. This Congress, topics such as agriculture, infrastructure, and national security will be front and center. The briefing covered climate concepts and terminology—from types of greenhouse gases to renewable energy technologies—to help you identify policy solutions at the intersection of these issue areas.
At this briefing, panelists showcased tools—like the EN-ROADS simulator, co-developed by MIT Sloan and Climate Interactive—that staff can use to easily digest climate data and generate policy ideas. They also highlighted federal agency resources essential to understanding the climate challenge and innovative solutions to address it.

The Columbia River

The Environmental and Energy Study Institute (EESI) held a briefing about climate adaptation, resilience, and mitigation strategies in the Columbia River basin. The Columbia, which winds through British Columbia, Oregon, and Washington state, is an important source of food, drinking water, irrigation, recreation, and clean energy for the Pacific Northwest. However, the effects of climate change have created and exacerbated problems like estuarine habitat loss, toxic algal blooms, low water levels, and diminished fish populations, highlighting the importance of finding science-based solutions to these issues.
This briefing also discussed the outcomes of the Uncommon Dialogue, which brought together tribes, national and local government, the hydropower industry, and river conservation stakeholders to identify shared approaches to steward river health and safety while ensuring hydropower operations provide clean, affordable energy. Panelists discussed the role of federal investments in the Columbia River’s resilience and health, including Inflation Reduction Act and Infrastructure Investment and Jobs Act funding.

The Tennessee River | Resilient and Healthy River Communities Series

The Environmental and Energy Study Institute (EESI) held a briefing about strategies to improve biodiversity and river health along the Tennessee River, which winds through Tennessee, Alabama, Mississippi, and Kentucky. The Tennessee River, one of the most biodiverse rivers in North America, experiences damaging issues ranging from PFAS and plastics to chemical pollution from landfills and manufacturing. These issues threaten both water quality and the health and well-being of the many communities in the river’s watershed.
This briefing highlighted the importance of effective enforcement of local, state, and federal clean water laws and regulations. Panelists discussed the role of federal policy-making in boosting river health, as well as opportunities to support biodiversity.

U.S.-China Engagement and International Climate Diplomacy

The Environmental and Energy Study Institute (EESI) held a briefing about the role of United States-China climate engagement in shaping the progress and outcomes of international climate governance.
