The greenest code is the code you delete. Old code does not sit still. Unused functions and abandoned feature flags still get built and tested. Libraries nobody calls still get scanned, shipped and loaded. A heavy library pulled in for one helper adds weight to every build. And to every deploy, again and again. Here is the fix you can use today. First, remove code paths and flags that nothing reaches. GreenCode's Constitution skill can help an AI coding agent find waste like this. Next, list every dependency in a software bill of materials. SPDX is the open standard format for that list. Remove the ones nothing imports. Then replace a heavy library used for one small feature. GreenCode researchers list dead code and unused libraries as an energy waste to fix. Less code shipped means less to store, send and load. GreenCode helps tackle this by mapping a codebase into a searchable index. Its full bill of materials shows which dependencies to drop or replace. That was GreenCode Tech Tip number forty-four.
