Tracing Global Emissions - Climate TRACE
The States and Regions Remote Sensing Project (STARRS) illustrates the value of collaboration in generating independent greenhouse gas emissions data.
Did You Know?
Research by Climate Group, as Secretariat to the Under2 Coalition, shows that states and regions with a recent inventory of emissions data are more likely to set emissions reduction targets.
What’s more, having access to a detailed breakdown of region-wide greenhouse gas emissions allows states and regions to identify their highest-emitting sectors and design and implement targeted mitigation strategies.
STARRS brings together Climate TRACE, Climate Group, and six states around the world to develop detailed, up-to-date, regional emissions data.
All of the states participating in this project previously had access to varying levels of emissions data, but many reported that it was difficult to source and generate their own inventories. As a result, their data were incomplete and often only updated every few years.
Climate TRACE is able to fill in these gaps and generate independent emissions estimates that don’t primarily rely on self-reported data. Climate TRACE pairs satellite and remote sensing data with artificial intelligence to identify emitting activities and calculate greenhouse gas emissions.
Through the STARRS collaboration, six regional governments shared data and provided feedback to improve the accuracy and relevance of Climate TRACE data.
ABOUT THE DATA
Climate TRACE’s technologically-advanced approach offers an independent look at emissions, providing states and regions with both complementary and new information to support their monitoring efforts.
Climate TRACE also aims to provide emissions data updates on an annual basis going forward.
To help our partners act decisively, we go beyond emissions estimates by sector or industry and break down aggregated data to detect emissions from individual sources such as power plants and oil fields. With this information, regional governments can take data-informed actions such as incentivizing efficiency improvements by major emitters, or introducing measures to help farmers switch to regenerative farming practices.
Review our methodology to learn more about how Climate TRACE estimates emissions and how it's different from the states' methodologies.
Located in central Italy, the Abruzzo region’s main economic activities are manufacturing and agriculture. Abruzzo’s last emissions inventory dates back to 2012. Climate TRACE provided updated data covering emissions from 2015 to 2021 for major sectors.
The pandemic effect on emissions: In Abruzzo, cement production decreased in 2020 due to the COVID-19 pandemic, but it rebounded significantly in 2021. Emissions reduction gains due to the pandemic were found to be only temporary.
Big companies’ emissions data for Basque Country is provided by the European Union’s Emission Trading Scheme (ETS). Climate TRACE methods incorporate satellite data and estimate emissions per road segment. This allows for comparison across different spatial scales.
A more granular view of urban road transport: The GHG emissions inventory measures emissions based on fuel sales and does not provide emissions estimates at the city level, but municipalities can take meaningful action with this level of granularity.
One benefit of collaborating with states and regions is that we can establish an emissions baseline and improve on it together. Using Jalisco’s baseline data from 2019, Climate TRACE created comparisons using AI and machine learning to see how emissions are changing in the region.
This project strengthened all the work we had been doing.
The impact of fertilizer: Modeling emissions from synthetic fertilizer, Climate TRACE found that our regional and crop-specific approach provides novel insight into how economic conditions affect emissions derived from agricultural staples like corn. As changes in the corn market shifted global production away from the USA and toward Latin America between 2016-2020, fertilizer emissions per unit of corn production declined in these regions. Climate TRACE data from Iowa and Jalisco shows how this global trend affected local GHG emissions.
Regional and state trends often differ from national trends across various sectors. That’s one of many reasons why states need their own data inventories and, in some cases, their own policies separate from national policies.
Big oil: In Pernambuco, oil and gas refining is a large local industry, and as a result, contributes to a large percentage of the state’s emissions, unlike the national inventory of Brazil where oil refining accounts for a small percentage of the total. The state can use Climate TRACE data to mitigate emissions from this sector.
The state of Querétaro’s most recent emissions inventory dated back to 2015. Climate TRACE data enabled the state to measure progress and begin taking action to create and update policies.
This project complemented our methods. It allowed us to have more precise data.
How deforestation affects GHG emissions: Between 2015 and 2021, forest, mangrove, and shrub-grassland areas have lost biomass, resulting in increased emissions. A potential driver of biomass loss is drought conditions in the region and throughout Mexico, which are considered the worst in 30 years.
Western Cape has the third largest economy out of South Africa’s nine provinces. TRACE data on large, intensive emissions sources such as livestock feedlots unlock opportunities to target policies aimed at the biggest emitters in the state.
This adds to our understanding of emissions. It allows us to check our emissions, compare to other regions, and fight emissions on a national scale.
Beef and dairy feedlots: We located 42 beef and dairy feedlots concentrated in the western part of the province, near Cape Town. Of the 42, 5 are beef, 34 are dairy, and 3 may be a mix of beef and dairy, all of which accounted for around 80,000 heads of cattle. Identifying the location and the type of feedlots is important for designing mitigation interventions, as beef and dairy methane and nitrous oxide emissions can differ in total emissions.
WORK WITH US
Use timely and granular emissions data and insights to inform your work to create emissions reduction plans and policies.
While our ultimate goal is to create emissions inventories for every state around the world, we prioritize projects based on opportunities for direct collaboration. If you’re interested in partnering, please contact us.
Climate Group through its role as Secretariat of the Under2 Coalition, brings together states, regions, provinces and other subnational governments committed to achieving net zero emissions by 2050 at the latest.
