This chapter aligns with Goal 14: Life Below Water and Goal 13: Climate Action by exploring the potential of marine renewables, including wind, wave, and solar, for providing long-term sustainable energy sources.

This chapter aligns with Goal 14: Life Below Water and Goal 13: Climate Action by exploring the role of viruses in the marine carbon cycle and describing how advances in marine virus research can improve marine ecosystem models and predictions of the future of marine carbon cycling.

Mobility as a Service (MaaS) is a recent concept that is gaining momentum in both the scientific world and the private sector.

Background: Climate change and air pollution are two major societal problems. Their complex interplay calls for an advanced evaluation framework that can support decision making.

Mitigating and adapting to climate change requires decarbonizing electricity while ensuring resilience of supply, since a warming planet will lead to greater extremes in weather and, plausibly, in

The role of science in influencing climate policy.

Mutual understanding is important when trying to make beneficial climate changes.

This chapter advances the UN SDG goals 7, 11, and 12 by reviewing the current state of hydrogen production and markets to determine the most economically viable routes towards introducing clean hydrogen fuel

This chapter advances the UN SDG goals 7, 11, and 12 by envisioning the biodiesel-from-microalgae plant of the future through the exploitation of genetically modified algal strains, renewable (mainly solar) power sources, and wastewater/effluent treatment facilities for nutrient and water supply with a one-step harvesting/lipid process.

This chapter advances the UN SDG goals 7, 11, and 12 by examining the current state-of-the art technologies applied for the extraction of compounds from microalgae/pretreatment and downstream processing for biofuels and chemicals from microalgae.
