The System for Greenhouse Gas Emissions and Removals Estimates (SEEG) is an initiative of the Climate Observatory that includes the production of annual estimates of greenhouse gas (GHG) emissions in Brazil, analytical documents on the evolution of emissions and a web portal to provide data and methodologies in a clear and simple form.
Estimates of Greenhouse Gas Emissions and Removals are generated according to the guidelines of the Intergovernmental Panel on Climate Change (IPCC), based on data from the Brazilian Inventories of Anthropogenic Greenhouse Gas Emissions and Removals prepared by the Ministry of Science, Technology and Innovation (MCTI), and in data obtained from government reports, institutes, research centers, sector entities and non-governmental organizations.
All five sectors that are sources of emissions – Agriculture, Energy, Land Use Change, Industrial Processes and Waste are evaluated with the same degree of detail contained in the emissions inventories. The data provided in SEEG’s Collection 5 is a series covering the period from 1970 to 2016, except for the Land Use Change sector that runs the series from 1990 to 2016. The period prior to 1990 is not covered by inventories of emissions. SEEG data are also presented in a form allocated by the 26 States and the Federal District. In 2016 the data allocation reached 96% (only 4% of the emissions could not be allocated in any state).
SEEG considers all GHG contained in the national inventory as CO2, CH4, N2O and HFCs and data are also presented in carbon equivalent (CO2e), both in the metric GWP (global warming potential) and GTP (global temperature potential), according to conversion factors set out in the 2nd, 4th and 5th IPCC Assessment Reports (AR2, AR4 and AR5). From Collection 5 the platform will present data using the IPCC AR5 conversion factors by standard, for these are the most recent and updated metrics (and also the factor used in the Brazilian NDC, but all other modalities are still available for consultation on the platform (e.g.: CO2e GWP AR2).
Data includes GHG emissions and removals and, available for consultation, Bunker data (emissions by international maritime and air transport).
Additionally, from SEEG Collection 4, an estimation of emissions and removals of carbon in the soil due to agricultural practices was included experimentally. These emissions and removals are not included in the national inventories of Brazil (NCI), but are an important part of achieving the goal of Brazil in the Paris Agreement (INDC).
All SEEG data are available on a digital platform, where you can query the data directly, as well download the complete database with more than 3.3 million records, already prepared for queries with dynamic tables. The main activity data used in the calculations are also available through the platform, where it is also possible to access infographics about the emissions by sector, methodological notes that explain in detail how the survey and production of are performed and an evaluation of data quality.
From 2014 SEEG began to be adopted in other countries. The first SEEG implemented outside Brazil was Peru, followed by India. The Global SEEG can be accessed through the following address http://seeg.world.
