What color is the ocean? 🌊🤔 It depends! Earth’s ocean can be green from phytoplankton, red with an algae bloom, swirling with brown and tan sediment, and many more colors. The color of the ocean can tell scientists a lot about ocean health and Earth’s climate. And, with the PACE satellite now in orbit, we’ll be able to see the ocean in more colors than ever before! 🛰️🌈 Video description: :00 Aerial view of ocean waves. A blue question mark covers the screen. A large red X replaces it. Quick succession of shots of the blue open ocean, blue-green water, red water with an algal bloom, turquoise swirls, green water and more. :12 Satellite images of green algal blooms in the water, followed by a poster about closing the area due to an algal bloom. :15 Animation of ocean chlorophyll data on a global map. The PACE satellite appears at the bottom of the screen. :22 Panning over more ocean color data on a global map. :28 Animation of the PACE satellite over Earth. The words “Plankton Aerosol Cloud ocean Ecosystem.” :33 Animation of the PACE satellite orbiting Earth, leaving data in its wake. Three circles appear. One has fish, one shows ocean and atmosphere exchange, and one shows global temperatures. #Earth #Ocean #NASA #PACE #KeepingPACE #Science

A tightening regulatory and technical landscape is redefining sustainable construction across the UK and beyond. The Building Safety Act is reshaping project governance by requiring transparent reporting and accountability that link safety with environmental sustainability in construction. Compliance processes are driving a shift toward whole life carbon assessment, embedding sustainable building design principles at the earliest design stage and quantifying both operational and embodied carbon.

Digital systems such as the government’s waste‑tracking initiative are enabling circular economy in construction practices, mandating traceable material flows and revealing the carbon footprint of construction through verified lifecycle assessment. These data‑driven mechanisms enhance resource efficiency in construction and reinforce the wider transition to low embodied carbon materials and eco‑friendly construction.

Investment is converging on decarbonisation at scale. A new £120 million waste‑to‑hydrogen facility is designed to transform residual waste into clean fuel, supporting low carbon design and resilient net zero carbon buildings. Growth in grid‑balancing storage improves the stability of renewable‑powered operations, a prerequisite for energy‑efficient buildings and low carbon building performance across portfolios.

Governance frameworks are also advancing. The creation of a dedicated leadership structure for the Greenhouse Gas Protocol elevates global consistency in measuring whole life carbon and encourages transparent benchmarking using environmental product declarations (EPDs). This maturity strengthens sustainable building practices, fosters green construction aligned with BREEAM v7 standards, and supports decarbonising the built environment through life cycle cost and performance management.

The cumulative effect signals a transition to net zero whole life carbon imperatives governed by robust data, certified materials, and measurable outcomes. The progress may appear administrative, yet it represents the essential infrastructure of sustainable material specification, circular construction strategies, and long‑term green infrastructure supporting a truly carbon neutral construction sector.
