What do greenhouse gasses have to do with energy systems? What even is a greenhouse gas, and if they’re such a problem why can’t we just ban them as we have with other harmful pollutants? Do cow farts cause climate change? Laura and Graham are joined by guest Dr. Theo Christiaanse who explains how we can track how fast we’re currently “spending” greenhouse gas emissions and how we can compare it to our global, national, or personal greenhouse gas “budgets”. Theo also explains some different types of technology we can use to make sure that our greenhouse gas balance sheet is properly balanced to meet goals set out by climate scientists.
