天大教授发表研究成果：源头减碳与后期除碳需双管齐下

Core Viewpoint - The research emphasizes that achieving carbon neutrality should involve distinct targets for source reduction and subsequent carbon removal, combining both approaches to mitigate negative perceptions of carbon removal technologies and provide new solutions for carbon reduction challenges [1][2] Group 1: Carbon Neutrality Strategy - The study advocates for a dual approach to carbon neutrality, focusing on both source reduction through renewable energy technologies and post-emission carbon removal methods like afforestation and direct air capture [1] - Current global climate policies primarily set net-zero emission targets without clearly defining the balance between source reduction and carbon removal, which may lead to reliance on future carbon removal technologies while continuing fossil fuel use [2] Group 2: Challenges and Solutions - The development of carbon removal technologies faces uncertainties regarding future investment scale, technical feasibility, and economic viability, which contribute to skepticism about their effectiveness [2] - The research team proposes setting independent targets for source reduction and carbon removal, which can lead to better outcomes in terms of short-term carbon reduction effectiveness, timeline for achieving carbon neutrality, and controlling maximum temperature rise [2]
