美国环境保护局和拜登政府宣布了四项针对发电厂的主要法规，旨在减少多种形式的有毒和全球变暖污染。这些规定于2024年4月25日宣布，是对燃煤发电厂吸热污染的首次法律限制，将加速美国电力部门的减排。
近期，经合组织（OECD）发布了一份关于韩国农村地区实现净零温室气体排放的政策报告。该报告深入分析了韩国农村地区在该国2050年实现碳中和目标中的重要作用，并依托OECD与韩国土地、基础设施和交通部（MOLIT）联合举办的会议成果。 报告首先概述了韩国农村地区的排放概况，并与其他经合组织国家进行了比较。特别关注了三个排放最多的行业：发电、制造业和交通。韩国农村地区在电力产生和交通方面的排放特别引人关注，这些地区对于国家整体碳排放贡献显著。 韩国的行动计划旨在通过多项措施达到碳中和目标。这包括对农村地区的可再生能源项目、可持续交通和生态友好型制造业的投资。报告强调，实现这一目标并不易，农村地区在公正转型过程中面临着就业风险和机遇。 报告还讨论了农村地区在实现气候中和过程中的挑战，特别是在确保转型过程中的公平性方面。例如，减少对化石燃料依赖可能会影响到依赖这些行业的地方社区的就业。因此，政策制定者需要考虑到这些社区的经济转型，同时也要考虑到环境保护的长远目标。 韩国的这一努力反映了全球范围内许多国家面临的一个共同挑战：如何在实现气候目标的同时，确保经济的可持续发展和社会的公平过渡。报告指出，这需要一个全面的方法，既考虑环境影响，也要考虑到经济和社会的多维度需求。 总体而言，这份报告为理解和应对农村地区在全球气候行动中的角色提供了宝贵的见解，同时也为韩国乃至其他国家提供了实现碳中和目标的宝贵经验。随着全球变暖的威胁日益加剧，每个国家的每个角落都需要积极参与到这场气候行动中。
本政策文件利用经合组织与韩国土地、基础设施和运输部(MOLIT)合作举办的一次会议，分析了韩国农村地区在2050年前向碳中立过渡过程中的作用。该报告概述了韩国农村地区的排放状况，并将其与其他经合组织国家进行了比较，并深入探讨了三个排放最严重的部门：发电、制造业和交通。论文接着描述了韩国实现碳中和的行动计划。它讨论了农村地区公正过渡的挑战，突出了就业风险和机会。
The Intergovernmental Panel on Climate Changes’ (IPCC) Sixth Assessment Report (AR6) has delivered another wakeup call about the need for drastic cuts to greenhouse emissions by 2035 to avoid the most devastating impacts of climate change to human well-being and ecosystems. Carbon dioxide (CO2) may be the most well-known greenhouse gas (GHG), but others, known as non-CO2 or short-lived climate pollutants, also have a critical role to play in keeping the Paris Agreement’s 1.5 degrees C (2.7 degrees F) temperature goal within reach, while also improving air quality and protecting health. , Short-lived climate pollutants — methane, black carbon and hydrofluorocarbons (HFCs), which are also sometimes known as “super pollutants” — remain in the atmosphere for less time than carbon dioxide but have a potent impact on near-term global warming. For example, methane has more than 80 times the warming power of CO2 in its first 20 years in the atmosphere. And about 45% of today's net global warming is driven by methane emissions from human activities. Moreover, methane is also a precursor for another powerful driver of climate change: tropospheric (ground-level) ozone.
The ocean is rising on the international climate policy agenda and the dialogues around it – 51 national plans include at least one measure aimed at ocean-based mitigation, compared to just 31 in the first round of nationally determined contributions (NDCs) – but will this translate into commitments to act? One clear change is countries’ recognition that the ocean is not merely a victim of climate change, but an important part of the solution. , New analysis from World Resources Institute has found that 77 out of 106 new or updated Nationally Determined Contributions (NDCs) – national pledges to reduce greenhouse gas (GHG) emissions - from island and coastal states include at least one ocean-climate action.
The science is clear about how to prevent increasingly dangerous and irreversible climate change impacts: Limit global temperature rise to 1.5 degrees C (2.7 degrees F), which means cutting GHG emissions in half by 2030 and reaching net-zero CO2 emissions by mid-century. , While countries, companies, cities and investors have announced some encouraging commitments to help achieve this global goal, they’re far short of what’s needed. Worse still, new research shows the world’s highest-emitting sectors — power, buildings, industry, transport, forests and land, and food and agriculture — aren’t acting anywhere near fast enough.
