Environmental issue in the context of "Energy technology"

Sustainable transport is transportation sustainable in terms of their social and environmental impacts. Components for evaluating sustainability include the particular vehicles used; the source of energy; and the infrastructure used to accommodate the transport (streets and roads, railways, airways, waterways and canals). Transportation sustainability is largely being measured by transportation system effectiveness and efficiency as well as the environmental and climate impacts of the system. Transport systems have significant impacts on the environment. In 2018, it contributed to around 20% of global CO₂ emissions. Greenhouse gas emissions from transport are increasing at a faster rate than any other energy using sector. A 2023 study published in Journal of Transport Geography found that shared electric bicycle systems reduce urban transport-related carbon emissions by about 108–120 grams per kilometre, particularly in non-central urban areas and when powered by low-carbon electricity sources.Road transport is also a major contributor to local air pollution and smog.

Sustainable transport systems make a positive contribution to the environmental, social and economic sustainability of the communities they serve. Transport systems exist to provide social and economic connections, and people quickly take up the opportunities offered by increased mobility, with poor households benefiting greatly from low carbon transport options. The advantages of increased mobility need to be weighed against the environmental, social and economic costs that transport systems pose. Short-term activity often promotes incremental improvement in fuel efficiency and vehicle emissions controls while long-term goals include migrating transportation from fossil-based energy to other alternatives such as renewable energy and use of other renewable resources. The entire life cycle of transport systems is subject to sustainability measurement and optimization.

Evangelical environmentalism is an environmental movement in which some Evangelical Christian organizations have emphasized biblical mandates concerning humanity's role as steward and subsequent responsibility for the care taking of Creation. While the movement has focused on different environmental issues, it is best known for its focus of addressing climate action from a biblically-grounded theological perspective.

Some Evangelical groups have allied with environmentalists in teaching knowledge and developing awareness of global warming.

An environmental organization is an organization coming out of the conservation or environmental movementsthat seeks to protect, analyse or monitor the environment against misuse or degradation from human forces.

In this sense the environment may refer to the biophysical environment or the natural environment. The organization may be a charity, a trust, a non-governmental organization, a governmental organization or an intergovernmental organization. Environmental organizations can be global, national, regional or local. Some environmental issues that environmental organizations focus on include pollution, plastic pollution, waste, resource depletion, human overpopulation and climate change.
