Anyone know of tools/methodologies for estimating embodied carbon and carbon sequestration potential of individual green infrastructure projects (e.g. bioswale along bikeway)? I've seen tools for the larger scale (e.g. land use change) as well as specific to trees (e.g. i-Tree), but these don't fully meet my needs.

Thanks!

Does anyone know of any Rebate Program for either induction cooking equipment or kitchen electrification (new or existing)?

In theory, the transmission losses in going from DC power from panels to AC for the building to DC for the lights would be eliminated. But does anyone actually have experience using this...

After reviewing BP language today with internal staff, we realized we'll need to add a glossary to explain industry jargon and technical terms that might not be widely used. I'd like to consolidate those terms onto one web page, a glossary. This probably should be on the list with the best practices, and it will need its own page. Thanks!
