Tetra Tech is Leading with Science® to support communities and nations around the world to adapt to and mitigate the challenges and impacts of climate change.
Tetra Tech’s multidisciplinary climate change experts bring more than 40 years of experience supporting government donors and private-sector clients to implement adaptation and mitigation programs in developing countries worldwide. We work at the regional, national, municipal, and community levels to integrate practical and locally led climate solutions across our sectors.
We integrate data and science-based solutions to design smart programs that result in lasting impact across our climate services. Tetra Tech’s team has deep expertise in monitoring and evaluation as well as data analytics and delivers advanced and accessible climate risk data for decision-making, both for our clients and for the communities we serve. We leverage our Tetra Tech Delta suite of digital technologies, including artificial intelligence and machine learning, to enhance our solutions.
Our experts are committed to a people-first focus, from conducting scientific and policy assessments to reducing greenhouse gas emissions and implementing effective adaptation and mitigation solutions. While the work is complex, the goal is simple—Tetra Tech works on behalf of our clients to build resilient and sustainable communities and nations in response to a changing climate.
We use integrated climate risk analysis to support evidence-based decision-making on adaptation solutions in key sectors, including agricultural production, governance, water resources, and infrastructure development. We work with our partners to conduct climate vulnerability assessments, develop scientific models to understand different climate scenarios, determine adaptation pathways, and support implementation and financing of actions that strengthen climate resilience at all levels.
Tetra Tech integrates climate finance tools into agriculture and food security, natural resource management, energy, infrastructure, and biodiversity conservation projects. We support national governments to design technically rigorous projects; build their capacities to become accredited implementers; and access formal climate finance sources such as equity, loans, guarantees, and grants. We assist communities and businesses to develop and benefit from carbon finance and credits. We also help businesses access more financial resources to diversify, manage climate risk, and adapt to the changing climate. Our expertise in climate and disaster risk finance enables international institutions and governments to deploy finance more rapidly in response to climate disasters.
Tetra Tech implements programs to accelerate the technologies and policies the world needs to achieve net zero and a just energy transition. We decarbonize utilities and modernize power grids. We promote equality and inclusivity in the global energy sector as well as at the intersection of energy and gender and energy-water-food. Our expertise includes scaling up renewable energy, increasing energy efficiency, and implementing market-based mechanisms such as emissions trading. Our clients are governments, policy planners, investors and lenders, power project developers, and development agencies. We work together to increase energy access, strengthen energy security, and power economies.
Tetra Tech’s industry-leading approaches and solutions mitigate the main sources of land-based greenhouse gas emissions, including deforestation, unsustainable land management, and land degradation. We work closely with governments, the private sector, and communities to develop improved management practices; stronger institutions; and incentives to better protect, manage, and restore critical forest and land resources. Our work also covers the full spectrum of REDD+ and climate finance delivery, including social and environmental safeguards; carbon financing and payment for environmental services; multisector and low emission strategy development; and carbon monitoring, reporting, and verification.
Tetra Tech offers world-class expertise in climate-smart agricultural technologies and practices. We use these technologies to identify and promote locally adapted, drought-resistant crop varieties, support sustainable intensification and water management practices, and help diversify and foster climate-resilient farming systems. We combine the technologies with climate vulnerability assessments to forecast future changing conditions in agriculture-dependent areas of the world, and use Earth Observation technologies, advanced artificial intelligence, and machine learning analytics, complemented with rigorous monitoring, evaluation, and learning for information-based decision-making and adaptive management.
Our scientists and engineers serve coastal communities through the entire project life cycle—from initial assessments and data collection efforts to the design and construction of critical infrastructure and restoration of coastal habitat. In addition to our work with our government and commercial clients in coastal sectors such as ports and harbors and sustainable tourism, we support ocean health through our work to reduce marine plastic pollution. Working alongside communities and our public and private sector partners, we leverage a science-based approach to advance marine biodiversity conservation and sustainable fisheries management.
Tetra Tech’s expertise spans the continuum of climate resiliency—helping urban areas prepare for, withstand, and respond and adapt to climate change. We focus on helping clients ensure the security of vulnerable and critical infrastructure and services, such as water supply, by using a comprehensive framework that recognizes system interdependencies. Our capabilities include climate vulnerability assessments, flood management and protection, and emergency preparedness and response. In addition, we support our clients to develop green infrastructure including building retrofits and LEED certification.
