carbonreduction

Carbon reduction refers to actions intended to lower net greenhouse gas emissions, particularly carbon dioxide. It covers strategies across sectors (power, transport, industry, buildings) and includes improving energy efficiency, adopting low-carbon energy, and changing consumption patterns to reduce demand for fossil fuels. The goal is to reduce net emissions and limit climate change.

Methods include: improving energy efficiency; electrifying end-use energy services; switching from fossil fuels to low-carbon alternatives (renewables, nuclear, hydrogen); fuel switching; and process changes in industry (e.g., in cement, steel). Demand-side measures such as energy conservation and behavioral changes can also contribute. Policy instruments like carbon pricing, standards, subsidies for clean technologies, and regulatory bans on high-emission activities support these efforts.

Key technologies associated with carbon reduction include renewable energy generation (solar, wind, hydro), energy storage, grid modernization, heat pumps, electrification of transport (electric vehicles and charging infrastructure), and carbon capture, utilization and storage (CCUS). Some strategies also rely on nature-based solutions, such as afforestation and soil carbon sequestration, to increase carbon uptake.

Measuring progress uses metrics such as annual CO2-equivalent emissions, emission intensity per unit of output, and sectoral targets, often aligned with national climate plans and the Paris Agreement. Challenges include upfront costs, technology readiness, intermittency of renewables, and ensuring equitable transitions. Achieving deep reductions typically requires coordinated policy, investment, and international cooperation.
