上述目标主要通过到2050年将世界主要能耗来源从碳基化石燃料（煤炭、石油和天然气）转移到可再生的零碳能源（风能、太阳能、水电、地热、海洋能及生物质能）以及核能来实现。
This can be accomplished mainly by shifting the world’s primary energy sources from carbon-based fossil fuels (coal, oil, and natural gas) to zero-carbon, renewable (wind, solar, hydro, geothermal, ocean, biomass), and nuclear energy by the year 2050.
