The credit crisis is casting a black cloud over the economy right now, but media companies continue to invest in green. TechWeb’s Financial Technology Network on Tuesday rolled out EcoTech, a new online resource covering green initiatives for business and IT decision makers at financial institutions. The site is designed to address the growing concern in the financial services sector about climate change, environmental issues and natural resource constraints. EcoTech’s tagline: “Reduce. Reuse. Return on Investment.”
