REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION

Description

Y02E covers technologies and methods specifically designed to reduce greenhouse gas emissions across the energy sector, including electricity generation, power transmission, and distribution systems. This classification encompasses renewable energy sources (solar, wind, hydro, geothermal, biomass), energy efficiency improvements in conventional power plants, grid modernization, and carbon capture or storage technologies integrated into energy infrastructure. Y02E applies to innovations that lower the carbon footprint of energy supply chains, from generation through end-user delivery. Adjacent classifications address GHG reductions in other sectors (buildings, transport, industry) or broader climate adaptation measures outside the energy domain.
