Ladies and gentleman, boys and girls, step right up… it’s time once again for the greatest show in the green business blogosphere: the Green Business Blog Carnival! Each week, green bloggers from around the Internets bring you some of the best green business content from the past seven days. Last week, our co-founder Triplepundit played host; next week, you can head over to the Eco-Libris blog for the Carnival’s next stop.

So, let’s get this show on the road… grab your refreshments, find a seat, and get in the mood with some appropriate background music…

This week’s Green Business Blog Carnival…

• Are you a Climate Hawk? Let’s face… green or not, business people often like to associate themselves with a sense of ruggedness… so executives and entrepreneurs promoting sustainability may not warm up to labels like “treehugger.” Chris Oestereich at Dystopian Present discusses a new label chosen by the folks at Grist: “climate hawks.”
• Editor’s choice — new regs for more efficient trucks: Tim Hurst at Earth & Industry discusses the the technological requirements that will allow trucks of all sizes to meet new fuel economy standards just announced by the Obama administration.
• The case for green publishing: Raz at Eco-Libris is getting warmed up for the Green Books Campaign (in which we’ll be participating) with a profile of publisher FIELL Publishing and their efforts to green up their books and business.
• Editor’s choice — Get your green copy found on Google: I’ve become a real SEO junkie over the past year and a half, so I really enjoyed Sara Radjenovic’s post on 10 great tools to help with optimizing your content for the search engines at Green Marketing TV (and I’m also a huge Market Samurai fan!).
• Buy a solar system online? Might sound a little scary, but Kriss Bergethon of Solar Sphere gave us some great insight into how they work with customers around the world in another sustainablog Approved profile.
• New business model for small nuclear reactor companies: Nuclear energy’s still pretty controversial in the green space, but certainly has its proponents. Tamar Cerafici of ANS Nuclear Cafe reports on a gathering of small modular reactor (SMR) vendors and suppliers to discuss business prospects… and how old models may not provide the most profitable paths forward.
• Editor’s choice: A greener supply chain through systems thinking: How do you green your company’s supply chain when you don’t control every aspect of it? Julie Urlaub of Taiga Company thinks systems thinking could help… and discusses her ideas at The Inspired Economist.
• HP as global citizen: Andrea Newell at Triplepundit discusses the evolution of Hewlett-Packard’s corporate social responsibility efforts… including a few rough spots.
