Take urgent action to combat climate change and its impacts

There is no country that is not experiencing the drastic effects of climate change. Greenhouse gas emissions are more than 50 percent higher than in 1990. Global warming is causing long-lasting changes to our climate system, which threatens irreversible consequences if we do not act.

The annual average economic losses from climate-related disasters are in the hundreds of billions of dollars. This is not to mention the human impact of geo-physical disasters, which are 91 percent climate-related, and which between 1998 and 2017 killed 1.3 million people, and left 4.4 billion injured. The goal aims to mobilize US$100 billion annually by 2020 to address the needs of developing countries to both adapt to climate change and invest in low-carbon development.

Supporting vulnerable regions will directly contribute not only to Goal 13 but also to the other SDGs. These actions must also go hand in hand with efforts to integrate disaster risk measures, sustainable natural resource management, and human security into national development strategies. It is still possible, with strong political will, increased investment, and using existing technology, to limit the increase in global mean temperature to two degrees Celsius above pre-industrial levels, aiming at 1.5°C, but this requires urgent and ambitious collective action.

Forests cover 30 percent of the Earth’s surface, are an important source for clean air and water, and are crucial for combating climate change.​

Sensors and analytics can assess the impact of temperature, humidity, and soil moisture on tree growth and their ability to absorb and store carbon from the atmosphere.​

The use of an IoT-enabled energy supply network comprised of smart meters and a smart grid can cut carbon emissions by almost 4% by detecting and adjusting to local changes in energy use.​

Sensors can monitor methane levels along oil and natural gas pipelines to resolve leakages of this greenhouse gas.​
