Forestry: Tree planting projects restore areas facing deforestation. Trees absorb and hold carbon. Without them, that carbon would be in the atmosphere, making global warming worse.
Agriculture: Farmers grow crops using technology and techniques to maximize resources and reduce waste when growing crops.
Renewable energy: These projects replace fossil fuel use with clean, renewable energy, such as that generated from a wind farm.
Water management: Projects get clean water to areas with polluted or otherwise contaminated water so that they can reduce the need to chemically treat or boil water.
Waste management: Projects capture the methane generated in landfills from waste disposal.
Carbon sequestration: Projects use carbon capture and storage to put carbon in places where it's unlikely to be released back into the atmosphere. They take carbon out of the air and store it in soil, in swamps, in trees and even in rock.
Energy efficiency: Projects aim to improve the efficiency of existing infrastructure by upgrading building insulation, for instance.
