Environmental advocates, their business allies and other non-profits are trying to resuscitate comprehensive clean energy and climate legislation in the Senate.

Today, after a forum sponsored by business, farm, environmental, labor and veterans groups-- featuring Sen. John Kerry, D-Mass, and other Senate and Obama Administration allies-- nearly 100 attendees from around the country dropped by Congress to petition their home state Senators. In early February, some 200 executives from the business coalition "We Can Lead" will fly into Washington to do likewise, followed a week later by a dozen business leaders from the joint environmental-business coalition, US Climate Action Partnership.

Both of these coalitions are also running advertisements--mainly in Washington.

We Can Lead, has a $1 million television advertising campaign, including an ad running this week, playing up the job creation potential of the legislation. USCCAP is also running print ads in Washington highlighting business support for the measure. Meanwhile, a veterans group called Operation Free has begun a two-month 17 state bus tour called the National Tour for Clean Energy, Security, focusing on threats to American security from climate change and dependence on foreign oil.
