Keeping climate change in perspective * 6 comments

Below is a text that I expect to deliver in rough form this afternoon at a rally in Concord for action on climate change sponsored by 350.org.

Climate/Energy Policy Updates * 6 comments

In this legislative session in Massachusets, we are not expecting much new legislative progress on energy issues, but at the federal level legislation is front and center. Congressman Ed Markey and Energy Secretary Chu seem to be leading us in a good direction.

Smart growth * 3 comments

Smaller housing units in high density areas are more efficient from both the building carbon use perspective and the vehicle miles travelled perspective.

Highlights of 2007-2008 session * 1 comment

Over the 2007-2008 session, I have spoken out and taken positions on many larger issues, but some of my most satisfying accomplishments have come from lower profile legislative work.

What should our carbon emissions reduction goal be? * 1 comment

Our goal should be to create an economy susbstantially independent of the burning of fossil fuels.

Recent Jim Hansen testimony — higher risks?

NASA scientest Jim Hansen argues that the concensus estimates of the rate and risks of global warming are understated.

Massachusetts strategies to reduce fossil fuel consumption. * 1 comment

Greenhouse gases in Massachusetts come in roughly equal parts from power generation, homes and buildings (mostly from heat, but also industrial processes), and transportation. Currently Massachusetts is moving forward very strongly on the first two sectors.

How will China’s growth affect carbon strategy? * 1 comment

China is a gigantic wild card with the potential to substantially extend the growth of carbon emissions world wide, even if developed nations get their emissions under control.  China is unlikely to control its emissions without dramatic assistance or heavy economic pressure from developed nations.

What is the carbon level we need to stabilize at?

To stop making the problem worse, we need to stabilize CO2 levels in the atmosphere – we need to stop putting out more CO2 than can be absorbed naturally.  Global warming is driven by the cumulative total amount of CO2 we have put into the atmosphere less cumulative natural absorption. 

What risk levels are associated with different levels of global warming?

2.0 degrees from pre-industrial levels — 1 to 1.5 from todays level — is a ceiling that some world organizations have viewed as troubling, but livable.    

How do emissions breakdown by country?

On a straight carbon dioxide emission basis, the United States accounted for 24.0% of emissions, highest in the world, and was 5th highest per capita in 2000 (only exceeded by Qatar, the United Arab Emirates, Kuwait and Bahrain).

How well are the European nations doing at reducing carbon?

European nations have suceeded in achieving a slight reduction in carbon emissions by switching from coal to gas for power generation. Overall, their energy use is actually increasing.

How do emissions break down by activity?

Available statistics allow an analysis of carbon emissions by broad type of economic activity.

How much renewable energy are we actually using?

Currently, the only renewable energy source which contributes a meaningful portion of the nation’s and Massachusetts energy supply is hydropower. 

How much energy does the United States import?

About 1/3 of the United States total energy consumption of approximately 100 quadrillion BTUs (“quads”) is imported, up from less than 1/5 in 1973.  Most of our net imports were petroleum.  We import roughly 2/3 of our petroleum consumption.

How much difference can individuals make by changing their daily direct energy consumption decisions — travel, electricity, home heating? * 1 comment

Roughly 40% of carbon emissions are under direct individual control – half from transportation and half from electricity and heating in the home (as a nationwide average).   An additional few points can be controlled by diet changes.

Massachusetts carbon emissions

Pursuant to the Global Warming Solutions Act, the Massachusetts Department of Environmental Protection has begun to produce Massachusetts Greenhouse Gas estimates which appear to be authoritative.

Calculating personal footprint

Links to online calculators and key numbers for personal carbon budget analysis.

Choosing personal carbon reduction goals

For a personal Kyoto compliance amount, figure a little over 5 metric tons — 11,000 pounds — of Co2 per year per person.

Livestock’s long shadow

55 – 65% of GHG’s from United States agriculture are attributable to domestic livestock (feed exports are not attributed to livestock in this computation).
