California, Texas high-speed rail: Better late than not at all

It has been reported that if high-speed rail were placed on the California ballot today the electorate would vote it down. While that may be true, it would not be a landslide defeat.

Development-oriented transit – Now there’s an idea!

In the past on the Air Quality Matters blog and elsewhere I have talked quite a bit about transit-oriented development or TOD.

Much painstaking work has been initiated to limit fossil-fuel burning so as to reduce the concentration of atmospheric greenhouse gases and therefore prevent any further related fallout. A complete moratorium on the burning of fossil fuels is the ideal. Being that this is not likely to happen anytime soon, it is, however, important to keep … Read more

At long last, a curbing-air-pollutant-emissions-and-greenhouse-gases focus

Where climate’s concerned, it’s simple math: 2 + 2 = 400

Carbon capture, fossil fuel, greenhouse gas, these are some of the latest and more common catch-phrases used when it comes to the conversation of climate change. Mention any one or all of these alliterative word-groupings and nowadays that’s guaranteed to move or stir the emotions which brings me to my next point. Two and two … Read more

Hitting 2030 GHG-mark harder with California driving-miles rising – 2

Greenhouse gas emissions in California must be at a level of 250 million metric tons of carbon dioxide equivalent (MMTCO2e) units. That’s the target for year 20301 as prescribed by Executive Order B-30-15 and California Senate Bill 322 and which amounts to a 181 MMTCO2e-reduction below the 431 MMTCO2e-figure, the goal established for 2020 or … Read more
