See for yourself, starting with photojournalist Gideon Leek’s article explaining the Documerica Project. For more detail, you can view the photos by category or searchable. pghrev.com/the-epas-70s...

Conceived by Bill Ruckelshaus during his first stint as EPA Administrator, Documerica was inspired by the famous photographs of depression-era farmworkers commissioned in the 1930s by the Farm Security Administration. legal-planet.org/2025/11/13/d...

How important are these sources of emissions? Consider that over a year, a landfill emitting 4 tons of methane per hour (in the middle of the pack of our “Top 25” list) would contribute about as much to global warming as one million SUVs or one large (500 megawatt) coal-fired power plant.

We just released our first list: The Top 25 in ‘25, an initial list of waste sites and landfills with the largest observed methane emissions rates globally for 2025. Click to see the most extreme methane emissions rates from landfills, from the US to Saudi Arabia. ucla.in/4pc7MWL

The UCLA Emmett Institute’s STOP Methane Project aims to make the plethora of data more visible, understandable, and usable in guiding and motivating efforts to cut methane emissions. We use public data from Carbon Mapper, a leading source of remote-sensed methane emissions data. carbonmapper.org
