Switching to light-coloured roofs and roadways would have the equivalent effect on greenhouse gas emissions to taking one billion cars off the road for eleven years. — © Steven Chu

I did a lot of work on energy efficiency at the White House. By the time I left we had taken the equivalent of six hundred cars a year off the road in reduced greenhouse gas emissions just in the White House complex.
When ships reduce their speed they use less fuel, resulting in fewer greenhouse gas emissions and other pollutants; the global shipping industry accounts for nearly 3 percent of global greenhouse gas emissions.
CO2 is a minor player in the total system, and human CO2 emissions are insignificant compared to total natural greenhouse gas emissions. Therefore, lowering human CO2 emissions will have no measurable effect on climate, and continued CO2 emissions will have little or no effect on future temperature....While controlling CO2 emissions from burning fossil fuels may have some beneficial effects on air quality, it will have no measurable effect on climate, but great detrimental effects on the economy and our standard of living.
I am troubled by the lack of common sense regarding carbon dioxide emissions. Our greatest greenhouse gas is water. Atmospheric spectroscopy reveals why water has a 95 percent and CO2 a 3.6 percent contribution to the 'greenhouse effect.' Carbon dioxide emissions worldwide each year total 3.2 billion tons. That equals about 0.0168 percent of the atmosphere's CO2 concentration of about 19 trillion tons. This results in a 0.00064 percent increase in the absorption of the sun's radiation. This is an insignificantly small number.
EPA will set a national standard for greenhouse gas emissions that allows auto manufacturers to make cars that people both want and can afford - while still expanding environmental and safety benefits of newer cars.
We have climate change caused by greenhouse gas emissions, mostly from human power and transportation infrastructure. At the same time, we have 2 billion people who live in energy poverty.
The best way to deal with climate change has been obvious for years: cut greenhouse-gas emissions severely. We haven't done that. In 2010, for example, carbon emissions rose by six per cent - the largest such increase on record.
Health care in the United States is responsible for a tremendous amount of waste and a significant amount of greenhouse gas emissions. For every hospital bed, the American health care system produces about 30 pounds of waste every day; over all, it accounts for about 10 percent of national greenhouse gas emissions.
For every $1 billion we invest in public transportation, we create 30,000 jobs, save thousands of dollars a year for each commuter, and dramatically cut greenhouse gas emissions.
The black line is carbon emissions to date. The red line is the status quo - a projection of where emissions will go if no new substantial policy is passed to restrain greenhouse gas emissions.
Factory farming is one of the biggest contributors to the most serious environmental problems. The meat industry causes more greenhouse gas emissions than all the cars, trucks, planes and ships in the world.
When you factor in population growth, it's clear that the mobility model that we have today simply will not work tomorrow. Four billion clean cars on the road are still four billion cars, and a traffic jam with no emissions is still a traffic jam.
Greenhouse gas emissions: Ultimately, stabilisation - at whatever level - requires that annual emissions be brought down to more than 80% below current levels
Although they [light and medium trucks] have only 5% of the transportation market..., they account for fully 35% of greenhouse gas emissions from freight transportation.
'Scientific' computer simulations predict global warming based on increased greenhouse gas emissions over time. However, without water's contribution taken into account they omit the largest greenhouse gas from their equations. How can such egregious calculation errors be so blatantly ignored? This is why man-made global warming is 'junk' science.
...if we all turned down the thermostat in our house by just one degree, we would save over £650 million worth of energy and nearly nine million tonnes of carbon emissions every year. That would be the equivalent of taking three million cars off our roads...we can bring about a Green Consumer Revolution in this country to improve our lives, enrich our economy and protect our environment.
