The Civil Aviation Authority of Singapore (CAAS) has launched the Singapore Sustainable Air Hub Blueprint (Blueprint) as part of its efforts to decarbonise Singapore’s aviation sector while enabling sustainable growth.

Background

The Blueprint aims to reduce domestic aviation emissions[i] from airport operations by 20% from 2019 levels (404ktCO2) in 2030 and achieve net zero domestic and international aviation emissions by 2050. This net zero goal aligns with both Singapore’s national climate target and the International Civil Aviation Organisation’s target for the global aviation industry. Alongside the Blueprint, CAAS will introduce 12 initiatives to decarbonise Singapore’s aviation sector and five enablers for the effective implementation of these decarbonisation initiatives. The initiatives will be implemented across three domains: airport, airline, and air traffic management.

The winter of 2022-23 brought historic levels of precipitation to California after years of deep drought, dwindling reservoirs, and groundwater depletion. In the first quarter of 2023, most of the state received rainfall exceeding historic averages, with some areas experiencing 200%, or even 300% of average levels. According to the US Drought Monitor, the state is currently drought-free, although some regions are still considered abnormally dry. Despite heavy precipitation over the past year, California’s drought resilience remains in question, as critical infrastructure projects face staunch opposition and climate change increases the likelihood of extreme and prolonged droughts. Regulators and water managers had a busy 2023 as they grappled with persistently low groundwater levels, planned for additional water storage and conveyance, and continued to advance water conservation initiatives.

This blog post summarizes key actions taken by state and federal officials in 2023 with respect to California’s water supply and provides an outlook for 2024.
