Understanding Net- Zero Emissions
Net- zero does not eliminating all emissions; it means balancing resisions with an equivalent compact of removal. This involves two parallel tracks: deep decarbonization of energy production and end- use sectors, and scaling up carbon dioxide removal methods such as reforestation, direct air capture, and enhancanced weathering.

Thee Core Role of Energy Economics
Energy economics studies howe energy is produced, transformed, difficed, and consumed, and how economic forces shape these activities. Three critical dimensions intersect with net- zero precises:
Market Incentives andCarbon Pricing
Putting a price on carbon is the mect direct way tu internalize thee socies cost of emissions. Carbon taxes and emissions trading systems (cap- and -trade) create a clear price signal that consumptes consumesses and houseds to reduce their carbon footprint.
