Climate and Resilience Solutions

ERG’s climate and resilience experts, including ERG’s Blue Earth Team, works at the forefront of public and private efforts to reduce greenhouse gas emissions and adapt for the future. We provide the full spectrum of climate services—from quantifying emissions to state-of-the-art mitigation and adaptation support designed to build community, environmental, and economic resilience at local, state, and federal levels. We work as practical visionaries in partnership with our public and private clients to develop and implement strategic solutions, including adaptation and mitigation strategies, as well as regulations and policies rooted in climate science. Our solutions include strategic decision-making approaches based on client priorities, conditions, and issues, as well as metrics and evaluation criteria to establish accountability and build trust and transparency. We ensure these solutions are informed by engaging stakeholders and local communities in well-designed processes each step of the way and by communicating clearly and compellingly to all audiences throughout the process.

GHG Emissions Quantification and Mitigation

ERG provides a full suite of services to support both voluntary and regulatory approaches to quantify and reduce GHG emissions. For example, we have helped the U.S. Environmental Protection Agency design, implement, and grow programs such as the Methane Challenge, AgSTAR, the Landfill Methane Outreach Program, and the Greenhouse Gas Reporting Program for more than 20 years. Our project teams include the full range of expertise needed to support mitigation projects through every stage, from assessment to action. ERG air quality specialists inventory, characterize, and quantify emissions at facility, sector, national, and global scales. Our engineers, economists, and policy analysts assess the cost and performance of mitigation technologies to recommend emissions reduction opportunities across a wide variety of sectors. ERG communication specialists work with clients to design outreach and partnership strategies to support effective implementation of reduction opportunities.

Climate Science

A solid understanding of the science—including causal mechanisms and impacts on earth systems, ecosystems, and public health and well-being—underlies all of ERG’s climate and resilience work. As a key contractor supporting several high-profile climate data and indicator initiatives over many years, ERG has acquired a deep familiarity with the best available observational data sources, which provide multiple lines of evidence to inform our technical analyses. Our experts and partners collaborate to analyze the best available global climate model projections. They also develop novel analyses that quantify and monetize climate change impacts and qualitatively assess benefits to communities and their local environment. Building on this information, they assemble comprehensive climate assessments at local, state, and federal scales. These assessments support ERG colleagues and clients in their climate adaptation, mitigation, justice, and resilience work.

Lindy Lowe

My favorite problems are the difficult ones—those sticky, multi-jurisdictional, multi-sector problems that require us to find new partners, develop new frameworks for working together, and be brave, humble, and kind. I love building frameworks that enable the person with the least amount of power and the person with the most amount of power to share their perspectives and contribute to solutions. Whatever the issue, my goals are to develop transparent, equitable, and effective solutions and to have fun along the way!
