European rules forcing all airlines to pay for carbon emissions are within the law, an adviser to Europe’s highest court said on Thursday (October 6), in the latest stage of a bitter battle (more…)

We can’t do it alone. And we don’t really want to.

We partner with the pros all of the time. We ask energy experts to help us with our energy assessments. We ask heating and cooling experts to help us with our Home Energy Audits. And this week, we’re partnering with a pro football team to get the word out about (more…)

Europeans believe climate change is an even greater threat than the current economic crisis, and second worldwide only to poverty, a new poll says.
