The primary means for reducing building GHG emissions are the following: Efficiency measures and building electrification Operations and maintenance Refrigerants: Low-GWP, minimizing volume, and improving management Renewable energy sources (on and off site) and energy storage Building-grid integration and real-time carbon signals Embodied carbon
Embodied carbon in buildings refers to the greenhouse gas (GHG) emissions associated with the manufacturing, transportation, installation, maintenance, and disposal of building materials and products over the entire life cycle of a building, not including the operations or use phase [8].
A carbon footprint reduction tied to specific maintenance actions is easier to defend in budget conversations than a vague commitment to sustainable practices. Keeping those numbers current is what separates a working sustainability program from one that exists only on paper.

Since buildings generate nearly 40 percent of global greenhouse gas emissions primarily the carbon dioxide emissions that contribute to climate change the building industry has a major impact on the environment. At the same time, we are dealing with resource scarcity.
Climate, Culture, Carbon Reduction. Robert Bevan assesses the threats to nature and humanity, and addresses how to heal the wounds already sustained.

Natural Building Materials Overview. Hempcrete offers you breathable, low-embodied-carbon walls that store CO as they age; you can pair it with other natural components to cut operational energy and create a carbon-negative thermal envelope when sourced and cured correctly.
