              Space technologies have led to a number of inventions that benefit the environment and save energy. Satellite-based systems are reducing vehicles’ carbon dioxide emissions, remote-sensing technology is making wind turbines more efficient, and information from weather satellites is helping solar cells to produce more energy.

Over the years, ESA’s Technology Transfer Programme and its Business Incubation Centres have fostered and supported many innovative technologies and business ideas that contribute to new services and products to mitigate climate change

These are just some examples of how spin-offs from space technology and satellite services can make a difference. 

  •   Space tech for renewable energy    
  • Space sensors reduce emissions from heating systems
  • Satellite data reduces car emissions
  • Changing lifestyles

Space technology provide important and essential information. As per worlds economic forum there are more than 160 satellites  which have been used to measure essential climate variables such as contribute monitoring of greenhouse gases, deforestation and industrial processes, change in  ice  polar caps, glaciers, sea-level rise, temperature.  Space technology are being used  as an early warning system, which would help in the early decision making. Space technology also help in tracking any weather change, wildlife crime. It also aids in climate change modelling, ozone layer observation.

Climate change is long-term shifts in temperatures and weather patterns due to variations in solar cycle and human activities such as burning of fossil fuels. It has emerged as one of the greatest challenges for the society caused by greenhouse gases making the earth warmer. The devastations and damages caused by climate change are visible across the globe.

Vegetative modifications have driven the snow leopard of central and South Asia to shrink or adapt to migratory patterns. Accumulation of greenhouse gases, resulting in climate change, is primarily due to increase of energy consumption and greater dependency on fossil fuels for human activities all over the world. The increase in temperature has ultimately led to modification in rainfall patterns, availability of fresh water and in sea levels. Since there is an interplay between climate change, human activity and state of natural resources, space technology has provided means to tackle some of the major problems posed by climate change.

A wide variety of satellite systems measures and monitors climate changes. Satellites and other space technologies can be used to mitigate the effects of climate change by which animals and communities can be protected.

  • Space sensors reduce emissions from heating systems. It can reduce gases that are harmful to the environment and fuel consumption.
  • Satellites provide accurate weather reports and warning signals for storms as it circles the globe. Everyday climate is also monitored.
  • Satellites cover the entire globe including impregnable mountains and deserts and more than half of the essential climate variables can only be monitored from space.
  • Space technology supports climate research and creates awareness of changes while stimulating implementation of mitigation and adaptation action.
  • Space technology has widened its horizon by monitoring climate change, weather forecasting, disaster management and rescue operations

While traditional means of data exploration and analysis are time consuming, costly and at times not accurate emergence of space technologies like earth observation (EO) such as remote sensing satellites and unmanned aerial vehicles (UAV) and internet of Things (IoT) provides new advances in data collection for monitoring climate change.

Terrestrial ecosystems are highly sensitive to temperature change and increasing greenhouse gas emission are a threat to disruption of ecosystem and its impact on biodiversity.

Space technology proves to be the foundation for understanding and analyzing climate change, enabling mitigation of its impact.

Earth-orbiting satellites, remote meteorological stations, and ocean buoys are used to monitor present-day weather and climate.

Humans—more specifically, the greenhouse gas emissions that human activity generates—are the leading cause of the earth’s rapidly changing climate today. The burning of fossil fuels like coal, oil, and gas for electricity, heat, and transportation along with deforestation constitute the primary source of human-generated emissions.

Satellites and other space technologies could be used to help mitigate the effects of climate change and to predict the weather, with meteorological forecasts able to act as early warning systems for extreme weather events.

• Satellite-based systems are reducing vehicles’ carbon dioxide emissions, remote-sensing technology is making wind turbines more efficient, and information from weather satellites is helping solar cells to produce more energy.

• Space sensors reduce emissions from heating systems.

• MethaneSAT, a compact new satellite is specifically designed to locate measure, and track reductions in methane emissions virtually anywhere on Earth.

• Green hydrogen, i.e., produced from renewable resources, is attracting attention as an alternative fuel for the future of heavy road transport and long-distance driving. It would reduce the global pressure on climate change, helping the transport sector to stay within a safe operating space.

• Satellites can now be used to track weather patterns and frontier technologies to tackle climate change.

• Space technology can also be used to improve agriculture – and for tackling wildlife crime.

Space technologies are an integral part of our evolution as a society. While we still have a long journey to evolve these technologies, we can utilize them to help mitigate climate change and ultimately safeguard our planet, too.
