Greenhouse Gas Emissions Mexico 2015

Here is a great Sankey diagram visualizing the greenhouse gas emissions of Mexico in 2015. This graphic comes from the ‘Sexta Comunicación Nacional y Segundo Informe Bienal de Actualización ante la Convención Marco de las Naciones Unidas sobre el Cambio Climático’ published by Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT) and Instituto Nacional de Ecología y Cambio Climático (INECC).

The Mexican national inventory of emissions of gases and composites withe greenhouse effect (Inventario Nacional de Emisiones de Gases y Compuestos de Efecto Invernadero) is compiled by INECC on a regular basis as part of its reporting as a signatory to the United Nations Framework Convention on Climate Change (UNFCCC). The report is here, you can find the graphic on pages 110/111.

On the left side we see the different sectors of the country and their contribution to the emission of the 665 Mt (megatonnes) of GHG gases in 2015. The unit of measure is Mt CO2 equivalents. For each of the sectors this is further broken down to the activities causing the emissions. Further to the right these emissions are split to the individual underlying gases,. We see a large share (75%) caused by carbon dioxide (bióxido de carbono), methane and nitrous oxides. 492 Mt CO2eq were released to the atmosphere, while 173 Mt CO2eq were sequestered (absorbed by plants and soil).

Landscape of Climate Finance

The ‘Landscape of Climate Finance’ is a project by the Climate Policy Initiative. CPI “works to improve the most important energy and land use policies around the world, with a particular focus on finance. (This) helps nations grow while addressing increasingly scarce resources and climate risk.”

At http://www.climatefinancelandscape.org/ the have put up graphically appealing and beautifully crafted slideshow with facts on climate finance. How much is spent? Where does the money go to? Who are the receiving countries. Please browse the slideshow here.

Below are two Sankey diagrams from the 2013 report on climate finance.

The first is a rather coarse overview showing the international funding of climate projects by OECD countries and Non-OECD countries. On the right side the recipients breakdown: within their own borders, OECD countries, Non-OECD countries. Details on the countries are available in the report. Flows are in billion US$.

The other Sankey diagram is more complex. Here we can see the sources of climate finance and intermediate agents, the instruments, the recipients and the uses (adaptation and mitigation).

The incoming flows from the left are mostly “not estimated” (NE) and therefore are not to scale with the outgoing arrows. There are many annotations on assumptions and constraints, so please don’t make conclusions directly from the image. In the online version one can hover over the nodes to receive more information.

Congratulations to CPI for this work. They are tackling a complex issue graphically, and make good use of Sankey diagrams for visualization.
