The Climate Service: Emissions Modeling and Policy Analysis

Rhodium’s Climate Service provides clients with greenhouse gas emissions inventory data, energy market and emissions forecasts, and consistent and timely research analyzing major energy and climate policy developments at the international, national, and US state levels.

For the last several years, Rhodium has been the go-to source for independent, rigorous analysis of the economic, energy market, and emissions implications of a range of US federal and sub-national energy and climate policies. Our annual Taking Stock report has become the gold standard for objective, up-to-date analysis of how legislative and regulatory action at the US federal and state level is bending the emissions curve, in a framework consistent with accounting methodologies of the US government and United Nations Framework Convention on Climate Change.

The Climate Service expands this toolset to include an emissions inventory and projection system for all 50 US states and, as of the start of 2020, global inventory data and projections for the world’s major economies. The datasets cover all sectors of the economy and the full range of atmospheric greenhouse gases (GHG), including methane, nitrous oxide, and hydrofluorocarbons (HFCs). Clients receive direct access to this proprietary emissions data, as well as our energy and emissions forecasts and analysis of major policies and developments, at the international, national, and US state levels.

Greenhouse Gas Inventories

Clients are granted online access to Rhodium’s economy-wide emissions inventories for all 50 US states and nearly every country in the world. Emissions for the years 1990-2017 are reported by sector and gas (for each of the six Kyoto Protocol greenhouse gases), based on IPCC GHG inventory methodologies.

Energy and Emissions Projections

Clients have access to detailed model output from regularly updated US economy-wide energy and emissions projections from RHG-NEMS, a modified version of the Energy Information Administration’s National Energy Modeling System, which is used to produce the Annual Energy Outlook. RHG-NEMS includes updated renewable energy, battery and other technology costs, macroeconomic and behavioral dynamics. It produces emissions projections for all 50 states, by year, through 2030 with projections updated on an annual basis to account for all major policy changes at the federal and state level. We also project changes in major energy market variables, including power generation capacity, electric vehicle sales, transportation fuel demand, and building energy consumption.

Starting in 2020, Rhodium’s Climate Service now delivers the same robust assessment of the GHG implications of current policy for the world’s major economies. We provide annually updated projections by gas and by sector through 2030 for China and India, and will be rolling out data for the top major economies in the months to come. Against this baseline, our interactive decision-support tools allow stakeholders to assess the GHG impacts of a wider array of options for major economies to ratchet their ambition through 2030.

Research Notes

Clients receive regular and timely Rhodium research notes analyzing major clean energy and climate policy developments at the international, federal, and state levels. Research topics range from state-level renewable energy policy to federal regulations to international developments. Our analysis helps clients understand the impact of legislative and regulatory action on economic output, energy markets, and emissions.


Clients access Rhodium GHG inventory data and energy and emissions projections through our ClimateDeck, a secure web portal tailored to each client’s workflow and needs. Clients can request the addition of any third-party data they would like to track and visualize regularly, including that from the Energy Information Administration, International Energy Agency, and Environmental Protection Agency.
